I did find it funny people were calling New World "unoptimized" to me it seemed like the exact opposite, they don't leave many transistors unused.

[@cacheman]

Using all transistors just mean a lot of resources are used, not that they're put to good use. Something being "optimized" carries some implication of resources used well. Especially in a GPU where a LOT of parallel work may simply be thrown away if a shader is poorly written.

[@defeqel6537]

@@cacheman I've noted the same with a lot of Battlefield games maxing out the CPU utilization. That doesn't necessarily mean it is well optimized for multi-core, just that it uses a lot of multi-core resources.

[@FrantisekPicifuk]

Not to mention that there is only so much you can do when it comes to optimalization for Nvidia cards. Developers have noted, that Nvidia drivers and their integration is like a blackbox, so any optimalization is much harder than integrating drivers for Radeon cards, that tend to be more open. So this migh actually be on Nvidia and some internal fuckery thats done on deep level inside their drivers

[@Dhaydon75]

The game kinda feels unoptimised but not how good it uses addresses hardware, it just scales really bad with man player models/cities and some other effects.

[@jabroni6199]

I’m gonna tell my power company they shouldn’t charge me so much once I start using every available amp coming into my home because My power usage is optimized.

[@10ghznetburst]

IIRC AMD was working on a per WGP clock management system, exactly to deal with stuff like this. The reason you get big fluctuations of power is because you get different utilisation factors on the SIMD units. E.g we have a GPU that issues SIMD32 instructions, one instruction operates on up to 32 points of data, but it's unlikely that in an actual scene you will always have 32 points of data you want to execute one instruction on. You may, for the sake of example only use around 20 of the 32 execution units on average, but then if you have small portions of your workload where most of the GPU suddenly has close to 32/32 utilisation of the execution units, you end up drawing a lot more power than before. Per WGP or SM clock management would require you to detect at a pretty low level what the utilisation factor is, and then preemptively choose to not issue instructions every clock cycle where you have many high utilisation instructions back to back, or alternatively change the clock speed before the transient gets out of hand.

[@JethroRose]

it's probably in both AMD's and Nvidia's interest to pursue this as being able to selectively turn off parts of the card (like Ryzen does inside the CPU) will mean it can run cooler, draw less power and thus opportunistically boost higher when required as it is cooler.

[@lrmcatspaw1]

[@andrewmcewan9145]

My friends 1070 would sometimes trip ocp on the power supply whenever you where loading something. Getting s bigger powersupply solved the issue but as you said proves that nv ignores short bursts. Turing was the first NVIDIA GPU: processing a 32-bit integer operation simultaneously with a 32-bit Floating point operation. Ampere increases the superscalar width to 2x FP32 operations per clock or 1xFP32 + 1x INT32 operation per clock. These additional FP32 operations per clock may lead to the more gross violations of the power limit compared to previous generations. Especially as fp32 probably has more transistors than int. A pascal vs turing vs ampure power spec violations in new world would be intresting to see but not nessarialy feasable. Although as you said this does make me conserned for using big ampure longterm.

[@Azerkeux]

I wonder why the 16 series cards were so locked down- I have both an EVGA 1660 and 1060 and the 1660 does not let you increase power consumption at all in OC software and have never seen it go over 125w where as the 1060 you can

[@benjaminchung991]

For consumers in the future - and ideally to try and drive manufacturer behavior - how hard would it be to include a look at the protections implemented in the VRM when you do board analyses on GPUs? What additional information would you need to conduct the analysis, beyond what's available from the PCB shots?

[@10ghznetburst]

You'd need to actually test the cards to see where they hit the limits or have board schematics to fully understand how they are configured. And anyway, I expect GPUs will start to implement more granular power management systems at a low level, to not issue instructions in a way that generates such transients, so it's likely not something that you'd be able to analyse at a board level.

posting here since alder lake is the new hype: can we get some rambling about the power delivery for DDR5 being on-stick now? maybe talk about the impact on PSUs and Motherboards now that from what I've heard, memory will run off of 5V, not 12V? I am not sure how much average PSUs are specced to handle of 5V, but I know in some cases that's not a huge number, and it could go up notably if DDR5 power consumption is higher, more so if boards/CPUs allow for higher density on consumer platforms (servers that support LRDIMMS, etc are already going to be specced for insane memory power draw)

You keep mentioning that know one will use all "transistors" on an RTX3090.. and you keep going to games, but actually 3d rendering hammers a GPU just as much as Furmark... Take this for what it is worth, but I imagine most people who buy the rtx3090 are not gaming... the return on investment over the rtx3080 is minimal.

[@michaelpascual2731]

What about using higher quality components for the power delivery system to be able to handle the problem of the spikes, and is this even possible, does better quality components even exist?

[@D3humaniz3d]

If you have more VRM phases that can share and distribute the load - the are going to last longer, since the load will be distributed. If you have higher quality components rated for higher voltages / power draw, of course they are going to last longer, by definition. That's why, if you intend to use a GPU for longer, you should basically pick whatever card has better power delivery components / better design. A good example of this is the POSCAP/MLCC fiasco at the launch of these [3090, 3080] cards. Cards that only had MLCC's (like the Strix and TUF) did not have any stability issues whatsoever. Meanwhile, everyone else who went with 5 or more POSCAP, had stability issues - at least from what I remember. Why did they use POSCAP's? Cause it's cheaper, nerd.

[@mmbr20]

Appreciate your analysis, thank you. I actually run mine at .850v 1800mhz. Would you say the longevity of the card will be increased?

[@Cinnabuns2009]

Xonotic (free simple shooter) at least on Linux benchmarks could cause quite high power draw so maybe also usable for showcasing things.

[@billgaudette5524]

If I run my EVGA 3080 FTW3 Ultra on the second vbios (105% power limit), and then set voltage and power to 100 and 105 each, the card will report over 400 watts drawn regularly in New World. I set it to 90/90 when I run the game just in case.

[@Cinnabuns2009]

I was messing around with my EVGA 3080ti ftw3 with pwr limit and voltage limiting and it will boost like all the time to 1950mhz @.9 volts and it will run happily there for what seems like indefinitely and @67deg C where as if I run the card at STOCK it boosts to over 2Ghz very very briefly, then gets to just over 80C temperature and down clocks itself to 1800-1850mhz and then runs there pretty much full time at higher power usage and temperature. In other words, my benchmarks are higher by quite a bit if I set the power limit at 85% or even higher with power limit at 100% but voltage curve max at .9v Boost was taking the card up to over 1.1v and that is on the default bios. So, if you're NOT undervolting, you're leaving performance on the table and also using excess power and then have to run your fans faster to cool down all the power usage. Seems like Nvidia really where just pushing everything to the max with this gen to lose less ground to AMD and there will be (I'd bet also like Buildzoid states) a spate of dead cards come a year or two which Nvidia happily loves... oh you need a new GPU? We have just the thing! Failure mode built in.

I dont know why they set it so aggresive, dont want to be in a sauna. Thanks for your input.

[@lllllllllllillllllll]

So running the VRM on high load and close to its limits is reducing the lifespan or killing the VRM? How does EVGA shipping out new cards resolve this then (apart from them blaming the soldering or w/e it was)? Seems untenable to just keep replacing them because high loads keep killing the VRM. Is it maybe also a combination with the high temps the VRM and memory modules are running at? I would guess if that's the case, then running a single or even double sided GPU waterblock would probably help. Or, do you think we'll see aftermarket cards running beefier VRM in future designs to avoid issues like these?

[@guycxz]

There probably aren't enough cards dying yet to make a more permanent solution more economically viable. Still, New World is unlikely to be the only game that can push the cards hard enough, and the VRM will probably be short lived regardless; hopefully enough cards die within warranty to actually make it more economically viable to make a proper card rather than hope it can last just until the warranty ends.

so getting to the point here, what you are basically saying is that maybe nvidia should introduce a more general type of auto downclocking feature in their future gpus. you cited AVX intel downclock as an example. however maybe that is not so easy for nvidia because they don't have something simple like AVX instructions to look ahead for. but i get your meaning: you mean do not go into such a restricted mode just only when detecting furmark program. but instead to the downclocking based on the general load being requested. and not to totally gimp it, but just to reduce the clocks down a bit further than usual to ensure a wide margin of safety so that it keeps it well enough away from any chance of blowing up catastrophically... but after repeating that i skrikes me maybe should that not be already something that should be incorporated within the existing firmware / software as a part of the inputs to the nvidia GPU boost algorithm? which is what dynamically controls the clocks.... this then goes back to the rumor that either a) NVIDIA was to blame in their driver for not setting the GPU boost correctly. or b) that NVIDIA thought their original / pre-existing GPU boost algorithm settings were already safe. however then with these new 3090s come along. then maybe the actual hardware design and power delivery was different than expected. or alternatively also possible (just like you mention) maybe there are some bad questionable components in the supply chain. which nobody was aware of. the thing is in retrospect it seems that the companies involved did internally investigate (using the new world as a test benchmark). and did eventually find out what is the culprit cause was. but this information was never shared with the public. and perhaps due to not wanting to make public and then forced into some very expensive product recalls. it's cheaper to fix in software and push out a new driver update. and also get the developer to patch their games. this would explain pretty adequately why we never really got the truth about it. because who wants to recall all those 3090s under current market conditions? it would be pretty awful situation to have to do that. still: you have a great point about them dying eventually further down the line. none of these companies would give 1 cent to care to protect the product adequately into old age. they would rather they al blew up after 3-5 years. so that it is clear out of warranty and then everybody has to buy new cards all over again. what annoys me about this is that: well people want to do that anyhow, regardless if they still work because the future cards will be so much faster. there is always a high enough demand for the latest product. so it seems kindda mean in that respect. since anybody who can realistically afford to buy a brand new cards (next time)... they will certainly buy them! and for those who cannot - that is simple because they cannot afford to keep buying cards all the time. so it's a policy that penalizes only the poor. and not the wealthy ones. so that is really where i take issue. it is also pretty bad for the environment too, for so many expensive products to end up as e-waste. sadface 😿

Hi there I live in Glasgow Scotland UK I preordered a 3xs sytem from Scan UK on 18/09/21 they start build stage 3 on 8/11/2 I've up until build stage 3 the day before to cancel.

[@transparentblue]

5:44 Two different definitions, optimization level could be defined as "how much of the silicon is that program actually using" or "how much render time does the prgram need for any rendered frame", in New World's case it's optimized if you go by the first definition whereas I've seen a few claims by devs that it does a needlessly complicated things on the rendering side meaning it would be unoptimized by that second definition. tl;dr: utilization vs efficiency

I can confirm that both my 980ti's have died whilst my gf's 970 is humming along just fine till this day. It is one of the lesser considered aspects of GPU shopping that the higher power usage will inevitably result in the high end options dying sooner most of the time.

Only an Nvidia problem.. Their approach to power management really spells "We hate users who don't upgrade every generation anyway..."

[@TrueThanny]

04:48 No it doesn't. It has 5248 CUDA cores. Prior to Turing, a CUDA core was a single ALU capable of executing either one FP32 instruction or one INT32 instructions. With Turing, that changed to a pair of ALU's, where one could execute FP32, and the other INT32, at the same time. The INT32 fact is important, because CUDA is a software library that includes integer math. If an execution unit cannot do integer math, it is not a CUDA core, by logical necessity. So when Ampere came out, and nVidia changed the "CUDA core" count at the very last minute to double the actual figure, it was a marketing lie. With Ampere, a CUDA core is a pair of ALU's, where one can do one FP32, and the other can do either FP32 or INT32 - the same as the sole ALU with pre-Turing cards. In practice, anywhere from 20-40% of that extra FP32 capacity ends up being used in games, with the average being about 25% at 4K. That makes the _effective_ CUDA core count, for games at 4K, ~6500. That's a far cry from the marketed figure of over 10K.

[@TrueThanny]

@Claus Bohm I'm talking about games. In a single-function app like Blender, the extra FP32 capacity is much easier to take fuller advantage of. Ampere is much better for compute than for gaming.

[@kotekzot]

I have a Zotac Trinity 3090, which was the only card I could get last year, and I even got it at close to MSRP. I flashed it with a VBIOS that has the power target set to 370W (it's a 350W card, as you know) and I have the card limit set to 105% TDP, so it's close to the max allowed limit of 390W. It runs at, or near, the 105% TDP in many workloads and has been like this for most of the time I've had it. I have a custom water loop, covering all the power stages, the VRMs, and a passive backplate. Is cooling something that is allowing the card to survive?

[@augustusbeard4528]

Could it be that the 8k results are just easier to monitor because the frames are longer so the transient response is might alse be longer? So the software update is fast enough to see the peaks compared to a faster framerate/shorter frame time? Also do you have any idea what information gpu-z uses to monitor power consumption? Because if its nvidia own shunt resister power monitor circuitry wouldnt that imply that the actual peak power is even higher than reported in software. Lastly if this is true, I understand that most electrical components are made to withstand pulses on a somewhat regular basis, though would the long term effects of these extreme pulse not degrade the vrm components itself or arent pulses that destructive for these components because of the relative little sustained temperature increase and short nature of these pulses.

[@arthurberggren5618]

Hey Buildzoid, completely off topic for this video but I was wondering if you happen to know which BIOS is best on a Gigabyte Z390 Aorus Pro WiFi, F12k or F11? I actually didn't even want the Aorus Pro. I wanted to buy the ultra or the master but they did not have any in stock anywhere at the time and if they did it was completely outrageous price. This brings me to a suggestion I have for a video for you. You could potentially make one for the differences in BIOS revisions on whatever motherboard seems appropriate. I know you have an oscilloscope so maybe measuring the differences in transient response, etc. I would also like to thank you for putting out such in-depth videos. I really wish more people would get a little more advanced when it comes to well everything really. I really appreciate your work and the time you put in. Thank you. Side note. I know a lot of people have trouble overclocking RAM on the Z390 Aorus Pro. I got mine to actually post at 4266 and boot into Windows at 4133 of course it was not stable. I was able to get 3800 15-15-15-30. 3866 however was not. This was all on F12K. I switched to f11 and 3900 and 3866 are stable at 15-15-15-30 all with really tight secondaries and tertiaries. Ram is G-Skill non-RGB 3200 14-14-14-34. Anything above 3900 I just cannot get stable. If you have any suggestions on how to get 4000 plus stable please pass on the information and thank you.

[@VargVikernes1488]

So does that mean that the fact, that New World is badly optimized on AMD gpus, actually saves them from going up in flames? Because I am pretty sure RDNA2 has the same transient power spikes, especially on always power-hungry 6900XT. Or does AMD manage power-delivery more conservatively? Also, do you think it's safe to unlock power limit through MorePowerTool to something like 360-370W on an adequately cooled 6900XT?

[@SolarianStrike]

The AMD reference 6900XT is actually using a 13-phase 70A vcore with TDA21472. The VRM is almost powerful enough to power a 3080 ti / 3090. Cards like the Nitro+ is just a reference spec PCB with extra fuses and RGB added. As long as you can keep the VRM cool you should be fine. Also the thing about the Navi 21, it is just a much leaner GPU compare to the 3090.

[@thorstenschroder7929]

I wonder if twice the capacity on the GPU-Side of the VRM could take away a little bit of the peak load on the VRMs. Or are the peaks so long that you'd need crazy amounts of Capacity to handle these situations. Also: Are there power-stages with higher ratings, or are we getting back into discrete MOSFET-Territory at over 60 Amps continuous ratings? So far my SMPS-Designs peaked at 15 Amps with MOSFETs that have continuous current ratings at about the value of the calculated peak-values. Another thing that just popped into my head: How close are they running the Inductors to their Saturation-Limits? As soon as the Inductor is saturated, it's resistive component (less than 1 mOhm) becomes dominant, which will effectively look like you short the GPU Power-Rail to the 12V Input-Rail for a few microseconds, before the Controller can turn off the Powerstage due to Overvoltage (Overcurrent should have tripped here, but doesn't due to mentioned design-flaws) or the maximum On-Time being reached.

[@camelCased]

So, when / if I get my 3060, should I underclock it just to be sure? I'm gonna use it for experiments with neural networks and Unreal Engine. So, I'm pretty confident I will accidentally write some clumsy code that uses 100% GPU. And also Blender rendering.

Realistically, the 3060 shouldn't be able to slam the limits that hard, as it's overall capabilities are much lower. The issue going on here is that the VRMs are getting slammed with rapidly cycling transients that are outside it's capabilities, based on the evidence available. The 3060 shouldn't be running quite so hard up against it's own hardware limits as the 3090 does with regards to voltages and power. Someone can correct me if I'm wrong on that, but I doubt the 3060 is likely to see such issues from violating power limits, just by it having a more conservative power limit and resulting headroom to begin with. If you are truly concerned, I'd start with underVOLTING, not underclocking. Undervolting provides lower power consumption, assuming the card doesn't ignore the limits put on it as part of the undervolting. Which would head off the issue of violating power limits. Undervolting also doesn't inherently hurt performance as much as underclocking does.

Hi Buildzoid, I have 2 question: 1. From the GPU-Z monitoring ; I can see that the 8-pin #1 voltage sometimes goes as low as 11.3V . From what I know, ATX specs calls for +-5% voltage tolerance on the 12V rail , which is 11.4V~12.6V. So is your power supply becoming faulty or GPU-Z reading is actually wrong ? 2. The memory temps hovering at 94 Celsius, looks like it might still increase. Is it dangerous to run at these temps if I'm expecting the GPU to last at least 5 years ?

A shunt mod is only for powerdelivery from the connector. The amount of amps drawn is determined by the GPU how much it needs to activate all its transistors. With a shunt mod you do not force double power going in to the core, but you basically tell the core that there's more power available if it needs it. The amount of power the core draws is basically based on voltage and frequency, which a shunt mod does not influence.

So with all of this being said, why dont these cards blow up left and right with the 500 and 1000w bios's? Using the 1000w bios my ftw3 would pull down 600+ w in port royal on water cooling.

[@guycxz]

The card's power monitoring measures an average power draw over a period of time. If a spike occurs that is shorter than that period of time, the power monitoring will only catch it after the fact, and it will be averaged with the power draw over the rest of the period of time being measures. So when the GPU gets hit with a workload that uses all of it it will try to draw as much power as it needs, and be limited by the power limit of the card. If the load occurs for a short enough period of time the card's power monitoring will not catch it until after the fact and will not limit it. Additionally, the power spikes in this video may actually be higher than presented, and New World should theoretically induce ones that are higher still. Edit: While it could be that a higher clocked GPU may spike even higher, though considering all the power modded cards probably have better cooling, the VRM may still suffer as much from it, perhaps less.

[@jdoggsgarage4494]

@@guycxz I fully understand that, but with a reported power draw of 300w do you really think there are transients when playing a game that are higher than what we see when benchmarking with a 1000w bios and seeing reported power draw in the 600w range?

[@guycxz]

@@jdoggsgarage4494 There may be. If the card doesn't down clock and gets nearly fully utilized, the power draw could potentially be huge. So much so that some cards actually tripped OCP before dying. If those cards had an OCP with similar values to those outlines in the previous video, you could potentailly see a current spike of 1000A. Depending on the voltage across the core, we could theoretically see a 1000W power surge that would be presented as much lower by the power monitoring. If we measure 200 times per second, or every 5 ms, and draw 1000w for 1 ms then 350W for 4 ms the average will be 480W, and that is what will be presented.

Well that is my understanding.

[@martinnyolt173]

From an engineering POV, I can understand why Nvidia takes advantage of power stages that have a rated "burst current". It allows for more boosting for short periods of time, without making a 24+ power stage VRM (which would cost a fortune, and much more PCB space). It just requires NVidia/the board partner to accurately monitor the current through all the stages and ensure that the "power stage boosting" is within spec (e.g. burst of 80A for 10µs, than stay below 50A for > 1ms, or something like that). Of course, this also depends on the spec for the power stage on the PCB, so adopting the GPU boosting to the power stages. I think that would be the right thing to do.

[@guycxz]

Honestly, considering the price of GPUs in general and 3090s in particular a 24 power stage VRM wouldn't be too unreasonable. I reckon they configured the power delivery as they did in an attempt the get more performance for the same price, but they flew too close to the sun and now some of their cards are on fire.

[@martinnyolt173]

@@guycxz As I said, I somehow can understand that approach. Generally, you don’t want to be too wasteful. Too many power stages can crowd the PCB, making it more difficult to route other signals, and eventually you would have to sacrifice the placement of other components, e.g. move the VDD/cache power stages further from the core (which worsens their performance), etc. At some point, a graphics card only has so much space.

@@martinnyolt173 Of course, however looking at how things are configured on the card, it appears the power spikes are left as they are by intention.

[@martinnyolt173]

@@guycxz Of course the power spikes are by intention. Let's say your GPU/cooler can handle a heat load of 300W. If 98% of the time, the GPU draws 280W for the load, then there is enough thermal headroom for 400W 2% of the time. This can be used to alleviate bottlenecks and increase FPS eventually. That's the whole point of boosting. However, it is not ok if Nvidia does not accurately monitor the current draw during boosting, and hence drives the power stages outside their spec. As far as I'm concerned, they could still use the same power stages, they just need to adapt their boosting to not overload them. Or, if they rely on their boosting to draw more current for their claimed performance, they need to select power stages which can handle the current spikes. But again, they need to be aware of the current draw at any time to know the required power stage spec.

[@arthurmoore9488]

Unfortunately, the answer is probably no. Now, the reporting tools won't show you the transients, and they may be happening at a lower frame rate, but they are still happening. Remember, the power monitoring circuitry is before the power smoothing circuitry, which is before the VRM. So, a sharp transient will be handled by the smoothing, but the VRM will still see it. Now, the good news. Those power stages are rated for high transient load, so a lower frame rate means they might have time to recover.

So, assuming current draw increases linearly with frequency, if the GPU attempts to run all cores at 1800MHZ we would get a current of about (1800/1200)*500 or 750A(!!!!!!!!) No wonder OCP is set to 800-1200A. EDIT: Assuming the current would increase linearly with both frequency and voltage, we are looking at a potential 750*(9/7) = 954.28A. Fuck. Hopefully CCL at least tames that a bit.

The voltage will go up with higher frequencies, and therefore current will go down, not up, at the same power draw.

​@@TrueThanny The power draw doesn't remain the same at different frequencies. If it had, the 3090 here wouldn't be down-clocking itself so hard when running Furmark. Generally, current scales with switching frequency in a roughly linear fashion for the expected operation range of frequencies, as transistors being toggled more times in reach time frame. this is a very rough approximation, since other parameters, such as the amount of time for which current is required, may change the average charge/transistor-activation ratio. As the frequency goes up, more voltage is required to maintain stability, which would mean the current flow per activation would be higher, this increases roughly linearly, but it is a bit more complicated than that and I don't know whether there even is a general equation you could use to approximate the behavior of a particular piece of silicon.

How applicable is this to the 3080 Ti? Since it's mostly the same as the 3090 but with half as much VRAM, does all of this still apply? It's crazy to me how most third-party 3080 Tis have a 400W board limit by default, when you're concerned about a 3090 with double the GDDR6X drawing over 350W. Makes me scared to see what's going to happen to my 3080 Ti if I happen to encounter these conditions.
