Finally, we will once again be joined by the Anonymous Server Engineer in the next Broken Silicon! He has been on many times before, and it's always a joy because he is such a veteran of the industry. Anything having to do with CPU architectures, AI, or datacenter GPU is fair game - but at a minimum we plan to discuss:

Recent AMD Security Issues

Recent Intel Raptor Lake & Sapphire Rapids Failure

AMD Ryzen 9000 & Zen 5

EPYC Turin

Xeon Granite Rapids

Future Intel Architectures like Lion Cove, Diamond Rapids, and Zen 6

The status of Nvidia & AMD GPU in Datacenter & AI

You have ~48 hours to write-in below! Just be concise, use good grammar, and be respectful to be considered.

Hey Tom and Guest I know this isn't on topic but how do you feel about Black Myth: Wukong being the new Crysis? Even the 4090 with DLSS Quality (75%) can barely play the game at 4k 60fps medium Ray tracing? I feel like this maybe the first true next Gen experience outside of Demon Soul Remake.

PCDog

Zen 5 seems to be polished and performing well under Linux. From a server perspective will this encourage more customers to buy Zen 5 based servers?

Resident Mexican

Hello Tom and guest, so with Intel's recent failures annihilating any trust gamers had for them, is the server market having the same reaction to these failures as the gaming market has? Are server clients scrambling to get off Intel or is it more subdued?

AnotherChris

Did you ever have a scenario where you saw a significant decrease in performance from one generation to another running the same software and OS on an updated server?

CompressedAIBlocks

Do you think it's time for AMD to move past any Zen based architecture with a fresh start similar to Bulldozer to Zen?

CompressedAIBlocks

How bad are the security issues arising in Zen compared to Skylake? Will we see similar performance regressions if they get patched?

CompressedAIBlocks

Zen 5 for client has been a mixed bag, with desktop being the weakest so far. How do you think this effects server customers? Will they just ignore these issues as their environments are radically different or will they stick with Zen 3 or 4 server based products?

CompressedAIBlocks

Do you think we'll be seeing RISC V or ARM based server products from Intel or AMD in the near future (5-7 years)?

10GHz Netburst

What would you say are the most interesting similarities and differences between the Rocket Lake situation and the Spectre/MDS situation?

10GHz Netburst

How would you estimate the scale of Raptor Lake deployments in servers aside from game hosting? What about in professional workstations?

SaltyInternetPirate

Do you see a push for AI from management at your job, and how do you respond to it? Do they even have a plan for what to do with it that they can sell?

Hello Tom and guest! As a consumer, it's starting to seem like a lot of the hype and buzz around AI and machine learning is starting to die down a bit. Is the wave of investment towards AI in data centers slowing down at all? Are data centers still buying up workstation GPUs by the pallet, or has ML hardware purchasing leveled off?

HaveAGoodDay

Do you think that Microsoft knew of how bad the Intel failures are, and how badly Zen 5 was performing and that was why they are so hyped about ARM? Do all X86 processor launches require a lot of tweaks in Windows?

Adept Soul

From what I can see, companies are still rushing headlong with AI. It's the new buzzword, and I don't see anything simple like reality stopping the rush, especially when upper management is telling them it is the future and what they must prioritize, no ifs, and or buts. Businesses are pouring tons of money into AI, but are they getting anywhere near as much out of it? I would be surprised if they were. How are businesses responding to the financial imbalance? Some companies may be responding with layoffs.

Adept Soul

The last I heard, a lot of the data center server GPU hardware is still on back order for a year or more. From what I can see, the marketing hype and buzz outside of the companies may have died down a bit, but the push for AI inside of companies hasn't. The upper management of many companies see AI as their future.

Adept Soul

Actually Zen 5 desktop for Windows 11 is weak, particularly with games. However Zen 5 still strong with Linux, and most of my computers run Linux, so I'm still very interested in it. Have we forgotten already that when Windows 11 came out, AMD Zen processors had performance issues that took a while for Microsoft to fix (after more than one update)? Most servers run Linux, not Windows, so I think Zen 5 server is going to be a big success, and cloud providers, and people running traditional data centers, both remote and on-premises, are going to be attracted by both the increased performance under Linux and the cost savings from reduced power consumption. That might not mean much on the desktop, but it means a lot to cloud providers.

Adept Soul

Not yet, but I think AMD was probably planning to do it over the next several years anyway. This is not a bulldozer moment.

Cleansweep

Has it surprised you that interfaces like U.2 haven't made the transition from enterprise to consumer for storage? It seems like consumers are stuck with M.2 or SATA, with no other options.

AI Generated Fish

Generally, product evolutions for enterprise have trickled down into consume markets however recently we're starting to see enterprise /data center products (even the "lower end") stuff be so far ahead of what consumers would even need. Do you think the AI bubble bursting night reverse this trend or will the gap continue to widen?

CompressedAIBlocks

Haven't forgotten anything ;) Just asking them a question.

Prior is the theme 999

To me, the only mistake AMD did was give these new products the moniker of “Zen 5” instead of “Zen 4 + (plus)”. Give it the marketing that its the same performance but lower tdp, with increased avx512 performance. I think it would have been received well that way.

Kiln God

Given AMD added proper support for AVX512 in Zen 5 do you believe this will improve AMD position in the datacenter? Also does AMD verses Intel verse ARM matter with the likes of Amazon making their own CPUs? Lastly any word on Apple servers?

Schattenjäger

Do you have any concerns for Zen 5 Server/Workstation performance given the terrible launch state of Zen 5 on Desktop?

Nicolas Terroir

Hello, with the rise of NPU in APU, do you see those NPU coming to server?

MinG3825

Hi Tom and guest. This time I wanna ask: 1. opinions on the VMware exodus and the replacements. 2. non NV GPU/ NPU adoption in the server market. Is the CUDA/ NV moat unbeatable? 3. thoughts on cloud vs on-premise 2024 Thanks

Chris Rijk

Welcome back Server Engineer - the previous time you were on you talked about a 37% market share as being an important tipping point for AMD. If current trends continue they should hit that in a year when measured by revenue and about 3 years when measured by unit volume. How do you feel about AMD’s position in servers, has there been any change in your perception about them since you were last on and do you expect their growth to accelerate or slow down?

Chris Rijk

Taking a basic high level look at server processors, AMD has their standard cores and their denser "c" cores derived from them, Intel has distinct p-cores and e-cores and a number of companies have ARM server processors which generally have a lot of dense cores. Do you prefer a few strong cores or a lot of denser cores? Do you prefer AMD or Intel’s approach here or are they about the same (performance, efficiency, features, support, etc)?

Chris Rijk

Looking ahead to the next 5 years in general servers, do you see any major developments that aren’t just “more of the same”? AI is currently driving a lot of R&D and could some of this spill over into general servers - for example, high speed memory or high end interconnects and networking.

Chris Rijk

There’s been a lot of discussion regarding gaming on Linux lately on the Moore’s Law is Dead Discord channel and I would say that this is mostly due to frustrations with Windows. Since Valve already has significant mindshare with PC gamers, could they realistically persuade a lot of Windows users to jump over to Steam OS and how would you suggest they go about achieving that? What about other Linux distributions?

Valko Milev

With the new lithography technologies(2nm ,3nm etc) for how long the cpus/gpus will run. Will they have huge longevity (20/30 or even more years) or a short one (5/6 years)? What is the current longevity of the current server grade cpus and gpus?What about mixed products like threadripper?
