Thanks for including some single thread benches, far to many people tend to ignore those since the total system throughput have become such a vital stat these days, but for some work loads the latency is also important.

Have some of these workloads hit a limit on their scheduling capabilities? Some of those Bergamo 9754 results seem anomalous. in how bad they are. The 9784X is a beast by all accounts.

Maybe a 16-core that is limited to 4 cores?

LV1Tech never disappoints with checking out these enterprise chips! Thanks for the awesome coverage!

If someone from the future had told me in 2016 that amd would have a 128 core monster of a cpu just 6 years later I wouldn't have belived it. The most impressive to me is how the embrace of chiplets allowed them to maximize yield and their wafer capacity; and paired to that the way they managed to alleviate the chiplet's inherent drawbacks. (remember the first epyc, it was great in some workloads but poor in many others). This embrace of chiplets also allowed them to iterate faster and tricle down the advancements to the consumer chips too. Finally the last strokes of genius are the avx implementation (from poor to better and more consistent than intel across the product stack) and the c cores with full functionality. Trully trully impressive for a company on the brink of bankrupcy. I hope they can do the same in the gpu front.

I'm just happy AMD's datacenter success is paving the way for Zen 5 R&D.

The Genoa and GenoaX graphs are labeled as 2P. Did you limit the test to 96 cores on those systems, or are those running with 2x 96 cores vs 128 on Bergamo? Will there be dual Bergamo boards too, since they are basically drop in compatible with Genoa?

Asus rack is my favourite though with no license cost for the IPMI unlike supermicro. Machine learning right now is kinda hard to get into fully, I run a Xilinx Alveo u250 FPGA accelerator for NN's but they're not super convenient to accelerate all types of models, or even port to. I hope that AMD is working on bridging the gap though with their new cards, I am a little disappointed that the Xilinx/AMD FPGA side of things has paywalls for some of their accelerators, as a dev I need to use these cards to actually learn to go into production environments, and don't want to buy the potato dev boards they have, I'd rather have what the company is going to deploy. For AMD to have a full edge on NV cards I think we need: - FPGA portion (which can be locked and changed in groups of cell's) - A plug and play solution to just using these accelerators with PyTorch/Llama models without converting to proprietary Xilinx stuff. AMD/GPU creators: - please, make GPU/accelerator cards memory up-gradable again, with AI we need to be able to put more than 256GB of vram, without having to buy another card when our model gets too large...

It's nice that they're increasing the number of cores per CCD. On no-so-old 24-core 74F3 (zen3) it was limited to 3 cores per CCD (the techno would allow up to 4 max for a 32-core), and the inter-CCD latency was absolutely horrible, making you regret not passing the data via a floppy disk instead, making it impractical to use for applications using more than 8 threads. On zen4 they increased the limit to 8 cores, which is significantly better for many workloads by allowing applications to run up to 16 threads with great performance. So if they raised that to 16c/32t with zen4c, that's even better and an awesome news, it will unleash all that power that was not usable before outside of clouds where you sell CPUs one at a time.

Well, unfortunately there are several reasons for that, number one being the fact that the T.A.M. on enterprise x86 is much larger than that of Consumer dGPUs. Also, enterprise customers ACTUALLY buy items on empirical data, whereas consumers, like consumer psychology has shown us for a long time, buy items for a host of irrational reasons, and this is what makes Nvidia's monopoly so hard to break. AMD could objectively release better GPUs that offer more performance for the dollar and people would STILL keep buying Nvidia just do to perception and the parasocial relationship Nvidia fans have formed with the brand. That and Nvidia spends an amount on GPU R&D that AMD spends on both x86 and GPU R&D and then AMD still have to compete with Intel at the same exact time and Intel is spending over 3x as much as AMD on R&D....in other words, AMD is competing against two rivals at the same time and both of them have access to significantly more financial resources, which makes it all that more impressive that AMD's able to do as well as it does, but also explains the limitations of the resources AMD has to compete against Nvidia.

3D vcache perfect random high load shifts

Sweet wooden floor!

i want one oh these monsters, just to plat wow vanilla and watch KZread videos, ad of course to admire the windows task manager

@Level1Techs Can you answer me these questions. With such an enormous amount of L3 Cache, can these be used (for fun and testing) with no "system/main memory".? If not (most likely not), can you show some kind of test that hits the CPU hard, but doesn't need a lot of RAM, and then test it with the full compliment of RAM vs a single 8GB stick.! That would be a fascinating test to see, although I cannot suggest any tests for you, but have noted that you saw some impressive increases in "DwarfFortress" with massive L3.

Epyc and Threadripper Pro are unfortunately out of my budget range. Prices in Canada are nuts. I built an Intel Xeon W7-2495X 24C 48T, ASUS ACE, 512GB DDR5 ECC system.

how about RAS?

100% AMD will pretty much remove the l3$ from the ccd and only have l3$ added to the ccd with the v-cache. instead of the cache being sandwiched between the cores it seems to me be logically to have the cache above/below the cores.

Would be great. But for now connections were removed to save space. Maybe when they axe "whole" L3 cache, they will use some space from this to have connections and have a L3 die on top.... or bottom of the package?

the problem with having cache above the cores is, the cores create heat, and that heat would go into the cache, which is very sensitive to high temperatures. Hence, currently 3D cache is only on top of L3 cache already on-die. Zen 5 will be the same, but I expect Zen 6 to fully utilise V cache from scratch (since Zen 6 design started after V cache was already functioning

@@VideogamesAsArt Yes. That is why they are also experimenting with cache being below and some other tricks with core topology. Details are unknown to me, but I'm certain that they are thinking about it really hard and have some of the smartest people on Earth working on it.

Whoever at AMD hook up level 1 thank you!!!!

I'm sure it will make a fine upgrade to my plex server

PLEASE! Test LLMs response time compared to A100, H100, 4090
