I had to check, if "Moore's Law" is the name of the theory stating that the number of transistors in ICCs doubles in a certain interval. Then I had to check again, if this channel's name is "Moore's Law is dead". And I must admit I found myself confounded by this complaint video, demanding nothing less than a relaunch of an entire processor family, predicated on the assessment that doing more with much less power isn't good enough. I had to unsubscribe, because there are a dozen YT-channels where I can listen to the same narrow point of view without the confusion about where we are with this technology. The name "Moore's Law is dead" at least suggests that the premise of the channel is that assessments are based on the realization that the semi-conductor technology is inevitably approaching a plateau and thus "generational uplifts" will become smaller and smaller as time goes on. P.S.: Windows 11 is rubbish.

My tinfoil hat theory is that they either intentionally neutered the standard SKUs to make their upcoming X3D look better, or they don't care because they assume anyone waiting for X3D was never going to buy the nonX3D parts anyway. Whatever gaming performance uplift they offer with these new 9000 series would need to be significantly outperformed by the 9000X3D chips in order for AMD to charge a meaningful premium for said X3D parts. Put differently, if any of the non-X3D parts outperformed the 7800X3D, that just makes "life" harder for the 9000X3D chips.

Welcome to Big Company 101. I've worked at many big (10,000+ employee) companies. This is, sadly, very common. Someone gets the CEO/VP/Board seat, demands 'kiss the ring' from underlings, and all the good people nope out or get laid off for refusing to tongue-punch fartboxes. Also, in such large companies, getting teams to work together is discouraged because silos drive efficiency (in the addled minds of leadership that can't lead, and managers that can't manage), so tribalism isn't just unfortunate, it's a direct result of...just...garbage tier leadership.

What am I missing from the Level1Tech’s CS2 data, at 1080p it’s more CPU limited, at 4K you’re more GPU limited. That said it’s really odd that all CPUs can throughput well over 300 fps at 1080p, but at 4K the 7950X is 5% slower than the 9950X, I can’t say I’ve ever seen results like that.

The person behind y-cruncher did a long blog with observations on the zen5 core, relevant to programmers. While most things are good, sse/avx/avx2/avx512 latency has doubled due to a 'core hazard'. I occasionally write this kind of code - 2c latency is far harder to optimize for, and existing code will hit penalties. Opinion: The design team can't have wanted this. Something either interacted badly, or they had to chicken-bit something important.

Things are different when looking at the Linux side of things. Expectations were generally met there with a ~15% IPC increase. The question is whose responsibility it is to fix things inside the windows kernel and scheduler. Part of it certainly is AMD but all of it? There are couple of other oddities creeping up. Anand tech’s testing shows something interesting in how multiple CCD’s communicate with each other. Half the cores in the remote CCD have an extra 20 be of latency which doesn’t exist going core to core on the local CCD. Gamers Nexus efficiency testing has some voltage anomalies which make me think things are ~50 mV higher than they should be. It doesn’t make sense that Zen 5 at the same clocks and a slightly better node is at that much higher voltage. This is also all in the context of a delay to their original launch date. AMD needed to push it back a bit but still with some extra time this so the mess at launch? And officially AMD hasn’t given a specific reason for the launch delay. Ultimately I think Zen 5 will be fine in the end as the issues are software based. The key components of the hardware appear to be OK if underwhelming right now. AMD has an event next week so hopefully things will be addressed then.

[@woobilicious.]

It's 100% Windows responsibility, It's their code, and they're the only people with access to it, and scheduler code is extremely complicated code that takes lots of planning and consideration. On the other side AMD directly writes code for Linux and submits it to Linus and Co for review, this is one of the reasons why Linux is so attractive to big corps, there's no bureaucracy and being put on the wait-list, you just write the patches, justify your code, have engineers tell you ways to fix it, and they accept it. There's no middle managers and finance department getting in the way saying "this has no monetary value, so we won't assign engineers to it". Linux also has market advantage of being used in Routers and IBM super computers, and ARM Android phones, They've had spent a long time writing flexible code that works in most situations. The new EEVDF CPU scheduler is probably why Linux is doing so well in these benchmarks.

Dual V-cache is significantly better than nothing at all. The Infinity Fabric is fundamentally flawed, part of the massive IPC increases AMD did is by changing the cache structure.

Sounds like they sure need something like this at AMD.

[@samuelrodgers2742]

Jim Keller only worked on the first generation of Zen. The Zen 2, 3, and 4 architectures have all been decent uplifts without Keller being involved. Zen 5 doesn’t look like a big uplift in gaming but its expanded AVX-512 instructions support and wider front end will very much benefit the datacenter.

[@woobilicious.]

Keller designs the team, not the chips, Apples chips are still good and that's because he got a blank slate to create a top team of engineers. You don't bring in an Engineer like Keller to build a chip and then leave you hanging after he leaves, he comes in, restructures the Engineering team, so they can keep churning out products, Keller isn't a magic silicon wizard who can magically manifest a uarch that's better than the previous generation. Zen 1 wasn't designed by Keller, When you make a CPU design you have to predict the future of software design and how people write code and also run simulations on existing code and see where the bottlenecks are, this isn't a person problem, it's a "how do we structure the team so it's really good at finding bottlenecks and building around them" problem, Zen 1 was already in the mind of someone at AMD, the Issue was trashing the dogshit philosophy they had when producing Bulldozer, AMD actually produced a Bulldozer chip with 40% IPC uplift near the end of it's life, but no one noticed. Zen 5 being a clean sheet, also means it's a longer projection, higher risk gamble, Zen 1 was pretty bad compared to Intel at the time as well, but getting lead times down from 5 years to 2 means they can be more align and flexible and adapt to new bottlenecks, and silicon issues, this is why Zen 4 is so good, because they had a good foundation to work off, Zen 4 was designed by the team, on top of the foundations of Zen 1, you can either stagnate like Intel did with Skylake, or AMD with Bulldozer, or take a slight risk by doing a clean sheet design that lay out the foundation for the next 4 generations, over 2-3 node shrinkages.

I bet AMD wants to sell Zen 5 X3D far more than regular Zen 5, even if AMD won't admit it. This is because the 7800X3D and 7950X3D outperform half the lineup except for the 9950X, but only outside of gaming where the 9950X gets trounced by the 7800X3D. And the 9950X is gimped of its true potential straight out of the box, because AMD decided to enable Core Parking on a non X3D CPU for zero reason. AMD, the employees who thought Core Parking was a good idea on the 9950X, please replace them.

The cross CCD latency is a very suspicious regression. I’ve seen HWINFO screenshots where the second CCD is clocked much lower. The whole things is really sketchy

[@riba2233]

Also inter core, that is a bigger issue

[@lharsay]

The clockspeed difference is probably intentional, AMD is pairing a higher silicon quality CCD with a lower quality one.

[@erkinalp]

Second core complex is purposely chosen from lower clocking dies.

[@Wasmachineman]

@@lharsay And they have been doing that since Zen 2.

[@Pacho18]

​@@lharsayOMG, they should be the same quality at least

[@JeffGraw]

Unless the huge latency between CCDs can be fixed, having v-cache on both CCDs sounds like it would provide very limited utility. You're going to want games to stick to one CCX anyway, so why put v-cache on both CCDs when it probably has to come with at least some sacrifice to clocks?

[@aperson7624]

The only reason that core parking is needed is because of the huge latencies. Using zen2 code base instead of zen 4 is probably why the latencies are so huge; they're doing things the dumb old way. So, once you tune the code to properly shuttle data between CCDs having Vcache on both CCDs would make a 9950X3D the undisputed king of code compiles and (some) games.

Thats what i am saying since forever. V Cache on both CCDs will not change anything. It might even get worse (because you also would have less Frequency and you will cut that away too if your Game would need that). Its totally fine to have only one if it works. Issue is it doesnt. AT ALL. Its like a Chance if it works or not. Like… Well. As long as we talk about Games that is obviously. I dont know about other Apps that need more V Cache. I understand thats a Thing too and i am not against AMD making Chips for them with 2 CCDs V Cache. But for Gaming it would be fine if it would work correctly.

[@JeffGraw]

@@flimermithrandir For me, if the penalty is

[@flimermithrandir]

@@JeffGraw And that’s an Ok Idea but you will still loose (a little bit) Performance with that Approach. And it will be more Expensive. It will show better Results in Charts but the single CCD CPU will still be better imo. I don’t want to sound like an Asshole. Really, I don’t. I just don’t see the improvement. I also don’t see how it would help with Energie. If both are activ, there is a Chance it will be worse. Even if not and Coreparking is still a Thing (which it should) it won’t do anything either. I would love to see it so we can test it. But I just think most ppl are thinking V Cache on both is a silver Bullet for Gaming and it will outperform the 7800X3D by another 15% and that’s just not true at all. It may still be worse than the 7800X3D. Hope you understand. It’s not against you personally.

[@Wolverine607]

I want more than 8 homogenous cores on one CCX within a single CCD.. Shame no such CPU exists. Intel maybe in Bartlett Lake has one. But Intel come on make 12 Lion Cove cores on Arrow Lake please. That way 12 cores on same tile and good latency. Not the stupid Big.Little crap.

[@SitWithAnkit]

All eyes on Arrow Lake now. Hope intel won't die before Arrow Lake.

[@Lady-Bug_]

you feed us those fake rumor for last 2 years

[@sangrevili3328]

Wait, wouldn’t the Zen5 micro code be basically the same between 9000 series & AI 300 series? Why is the mobile Zen5 preform so much better vs Zen4 compared to what we are seeing from the desktop skus? And wouldn’t the same “windows” issues be effecting AMD’s AI 300 series? Yet we haven’t heard anything about issues with the APU’s.

[@MooresLawIsDead]

It isn't. Listen to the podcast that came out next to Strix - we said we think it's not done.

[@05DonnieB]

I have to wonder what Lisa is actually doing daily at AMD. There is such a clear disconnect between engineering and marketing. I don't know if engineering is handing marketing legit numbers and marketing then makes up new numbers or vice versa. We saw the terrible marketing with the pointless 5900XT launch, which proved to be 1% faster than a 5950X. Lisa needs to get both parties in the same room and have a very uncomfortable conversation. Is she respected?

[@AbeDillon]

Why would management OK the Zen2 team using the Zen2 codebase for Zen5?! That sounds bananas.

[@brah_ddah]

It feels to me that if this was always going to be the case for launch, they should have changed the core counts meaningfully.
