[@Squiggly667]

It still baffles me that neither AMD nor Intel sell 'naked' CPU's with no heatspreader for enthusiasts. Remember when AMD's Athlon XP series were just exposed CPU's on the die? I'd love to not worry about killing a CPU from de-lidding. They could even upcharge for the 'enthusiast' CPU's while saving money on solder and a heatspreader and enthusiasts would flock to buy them. The companies could even bin the CPU's to ensure max performance and clock speeds. Much like Silicon Lottery used to do as a third party.

[@ThomasWinders]

I was thinking the same exact thing lately. I remember the good old days where Amd and Intel cpus were barenaked.

[@matgaw123]

It all because of warranty

[@es-br8ck]

Exactly because of people bending and breaking the CPU PCB like our guy did here. And RMAing it. The IHS has several functions, including structural integrity of the chiplets.

[@wayland7150]

There's no point in de-lidding and then putting the lid back on with liquid metal because it was soldered to begin with.

[@snowpuddle9622]

there's no point in doing any overclocking or tinkering, gains are abbyssmal

[@dawudmc]

Less waittimes in rendering, more frames in Games is not the same as replacing solder with liquid Metal g​@@snowpuddle9622

[@shadowarez1337]

If they'd maybe reduce the IHS by 50% thickness that'd be great.

[@yosixxx]

the solder is almost always not evenly spread out and even if it is, liquid metal is better at conducting heat

Hey FC, thanks for doing the video, I actually delidded two 7950x & 7950x3d already with no issues. Maybe that 7800x3d with only 1 ccd has problem with pressure dispersion and that is why it cracked.

Imagine if they made a Ryzen 11 7990X3D, but instead of 3D stacked cache on top of the die, they put 512MB of L4 cache on top of the IO die

[@denvera1g1]

@@zihechen3111 you cant reduce latency, by moving farther away from the core

[@denvera1g1]

@@zihechen3111 The cost of the cache is wildly over-stated This is the same silicon used in the RX 6500XT which was selling for $100 The cache is rougly 30mm² doesnt include memory, doesnt include fans, doesnt include power delivery or licencing fees for the HDMI and DP ports. The 6500XT on the other hand does include all of those things, is 107mm² instead of ~30, and often comes with 2 free games, for $100, this cache is dirt cheap, and so are the CPUs, that 5950X was is cheaper to manufacture than the RX 6500XT, yet it was selling for what, 5-8x the price? On the subject of cache, You can get at least 256MB of L4 on the 5800X3D and 7800X3D in addition to the cache on the CCD, if you take the same cache thats used on the 5800X3D, and instead of cutting it to this tiny little thing a few mm wide and long and slapping it on top of the reletively small CPU cache, you instead cover the entire IO die. This can do 2 things. If you no longer place cache on top of the CCD, the CCD can now run at higher frequencies, and 2, by placing the cache on top of the much cooler IO die, the cache should be able to be more dense due to the lower thermals I mathed it out, taking the same cache density found on the 3D chip of the 5800X3D(64MB at roughly 30mm²) then instead of chopping the wafer up and using inactive silicon to cover the rest of the die like on the current X3d chips, they could just make a cache chip the same size as the entire 122mm² IO die for at least 256MB Ideally for efficiency you should still keep the 64MB of cache on top of the CPU cache, but by having this 256MB of cache on the IO die you're reducing the needs to go to system memory, reducing latency, and reducing power consumption. Just look at how efficient the 5800X3D and 7800X3D are, better performance than their non3D counterparts, while using significantly less power. Sorry if i'm a bit rambly, its late and i have been up late for the past 4 days

[@denvera1g1]

@@zihechen3111 The Apple M1 does use its cache smartly, but one of the reasons the M1 is so efficient is not because it has a huge cache, but because it has the power of a small dGPU, and instead of a seperate package+RAM for the CPU, and GPU, they both share the same pool of RAM and are on the same die. this means they dont have to pass through the motherboard to talk to each other, they technically dont even need to pass through the package if designed right, it could all go through silicon. The AMD 2400G, 3400G, 4750G, 5700G, 6800U and upcoming 7840U/Z1Extreme are also designed in this way(apple was not first at this, AMD has been doing APUs for years as most consoles are built on AMD APUs) The 5700G is crazy efficient, with the right RAM, you can get similar performance to a 5800X plus a GTX 1050, with the whole system using less power than the 5800X by itself, what really held the 5700G back was the vega architecture used in the GPU, which was basically 4 years old at the time the 5700G launched, yes you could close those 8 vega cores fast puwshing the 5700G to around 80w, but just cant make up for the old architecture. For reference, the steamdeck APU uses just 20w PPT, has the same number of GPU compute units as the 5700G, but offers better GPU performance than the 5700G (at 60w) thanks to the use of RDNA2 They're even both on the same process node, so it cant be argued that its only faster because one is on 7nm, and the other is 4nm

Many years ago, the difference between modding and stock - depending on X,Y,Z was often large. That remains the case today, but in some cases, and this is one - its interesting to see that the vendor has what is a hard to mod piece of engineering, and yet, its good out of the gate, and close to its maximum in a general sense.

Thank you for your honesty the 7800x3d is a really good gaming cpu and not for overclocking. Its already running on limit and i wouldnt recommend anyone to touch the settings. But slight undervolting could help for better thermals and powersavings.

7800x3d is overclocked to 5.4Ghz already two weeks ago and its boost up to 5.6GHz, all without delid. kzbin.info/www/bejne/b2G4c4inZtJ_fbs

You could use PBO and negative CO offset to gain performance if their is thermal headroom with undervolting and jsut let the chip keep boosting til it hits the limit

[@walterrankin200]

I'm 68 yo, been away from computers for thirty years just came back in January and have delidded a 7950x3d and a 7900x successfully using Der Bauer's tool and have the mycro water blocks on both. I did not find it difficult to do and used Liquid Metal for the first time also. They were both thermal throttling on Cine bench 23 before, now they top out at 78c and 81c respectively. My scores increased by about 10%-15% by delidding.

If my 12700K has a constant 8-10°C delta using an AIO, would it benefit from lapping the IHS in this area? Diff paste, repaste, contact frame, and still there consistently from idle to heavy load. Not causing any issues, just bothers my OCD 😅

[@diomedus]

Try undervolt the curve optimizer on all cores to negative 20(mV), i found out my cpu can handle negative 30 and more but it is not as good and have lower skore on cinebench, by benchmarking i found out negative 25 is a sweet spot for me, gained about 100Mhz on all cores under stress, lower voltages and with the same temperature on AIO water cooler, approximately i gained about 1000 skore on Cinebench R23. But ! i have SK-Hynix 6000Mhz Ram from Gskill 2 sticks, BCLK/ inifinty fabrik set to 2033Mhz, UCLK/MCLK to 1:1 gear ratio and custom safe timing from Buildzoid for those RAMs. My system is working really well i dont do any stuff like deliding or grinding the IHS and because X3D CPUs were not build for OC you have few options to gain better performace. PS. this video is 4 months old so dont know if you do this but update your BIOS.

[@quintrapnell3605]

I wonder is Msi Kombo strike is a thing for this cpu like it is for the 5800X3D. It doesn’t really add much performance but it does lower temperatures and power consumption.

[@juno1597]

Seems like X3D Cpu's are constrained by their voltage and design, X Cpu's on the other hand seem to scale very well with anything you throw at it.

it's a gaming cpu for a reason, sadly amd don't have universal cpus for gaming and production

All in all, If you ask you me, anything less than 10% is margin of error and I wouldn't even worry about it. The best thing to do is leave it stock or undervolt and power limit or use eco mode (If you can). All this work for 2% is definitely not worth it all.

[@thefinalroman]

how did u overlock it?

[@harshhell4185]

The temps are high, especially in SOTTR. The effective clocks were dropping quite a bit also. With custom water cooling I’d be shocked. I’d be interested to see how much Curve Optimiser brought those down. My 13900ks stock was crazy high, but with a simple undervolt it’s very rarely hitting 60c in gaming, and that’s with an AIO without delid etc.

Yeah the Intel chips come crazy overvolted from the factory but they can be power limited and tuned to a great level where you can get great performance and reduce the heat and power consumption Exponentially.

this CPU does not need 2 connectors, it never pulls above 90W. One connector is good for 300W. Why would you need 2 connectors for 600W when you only consume 90W? Do you know numbers? 90 is much smaller than 300.

Imagine a 7740G3D Sure, only 48MB of cache instead of 96MB But its monolithic 4nm, instead of chiplet 5+6nm, meaning there is far less latency to RAM and the RAM can run at much faster speeds thanks to the 4nm IMC Would i like them to make 32MB non3D versions of their APUs?
