The best videos are the ones where you excited about the subject. AMD has put themselves in such a good spot with chiplet design.

[@chrisbullock6477]

Intel has done well but only in the past 4 years due to AMD's continuous innovation. Thanks to Dr. Lisa Su they have made very strategic short and long term technological and business decisions that will reap their full benefits probably within the next 4years across the board. Basically completing 10 years since ZEN/EPYC/NAVI have come on the scene.

You must be young. My first PC had 1MB (that's megabyte) of RAM. Many CPUs these days have that much or more L2 cache *for just one core* than that! Now, I'm sure there are people who started out with IBM XT or something. More older to you, then (LOL).

Cities:Skylines 2 is promising to fully take advantage of all cores, stating the only limit on the simulation size will be your computer.

[@Aleblanco1987]

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.

[@renerebe]

[@denvera1g1]

Remember those HFT focused Xeons from 2009, those "2 core" monsters that ran at 4.4Ghz, but was really a 6 core with 4 cores dissabled, and then all of the cache available to the 2 enabled cores, man the X5698 was an amazing beast, especially if you could firmware unlock those cores and water cool it. Imagine they do that here, 24 cores, 1.1GB of cache, up to 92MB of cache per core if you only use one core per CCD

[@tcnymex]

I can still see where some of my workload might benefit from such a chip. (More cache per processor the better for large matrix inversions, f'rinstance) Are there more recent xeons than 2009 that use such a "disable some cores to reallocate cache" strategy? Maybe a 16-core that is limited to 4 cores?

Now AMD has "building blocks", as in packages, for heterogenous multi-socket solutions, with 4c+4x3d for mem/cache intensive and/or core intensive NUMA nodes ;) On the other hand, working in corporate big data processing I can see benefits to 4c... where previously devs had to pull double duty by rebuilding for up to 128 cores and by replatforming for ARM ISA, now they can focus only on core usage... or they can focus on better large cache optimisation options for x3d.

[@matilija]

1.1GB of cache...holy crap, my first PC had 1 MB of memory, 4x256k chips, the cache for the chip was external on the board, and I think it was 32kb for that particular board...though it could have been 16 or 64, I don't really remember 100%, and a 40 mb HDD...and honestly, I never thought I would need more, it was so overkill for that old 20 mhz 386 at the time, oh how far we've come in such a short period of time.

[@not-another-dev]

NGL, you should be part of AMD Wendell, you do a good job of marketing their server side of things. I keep looking at Genoa I currently have a 7551 Epyc for my workstation, but definitely my next rig will be Epyc again. I think my only gripe is the lack of normal IO on server mobo's a lot of people prefer Threadripper but I honestly love having IPMI which. 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... I want to run more than one network at once...

[@tcnymex]

About Genoa 16-core three-quarter gig cache chip, is that hard wire 48MB per core? Or if I'm not using all the cores does it dynamically allocate more cache per core? (i.e. if I specifically write my code so that I'm only using 4 of the 16 cores, do i get 192 MB per core?)-

[@dllsmartphone3214]

i wish AMD on CPUs would do the same great job with their GPUs

[@post-leftluddite]

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.

[@SomeUserNameBlahBlah]

The money is in data center CPUs and laptop CPUs. AMD almost went bankrupt prior to Zen. Add that general consumers will buy Nvidia even if AMD produces a superior GPU, and you start to see why AMD focuses on CPUs.

[@PineyJustice]

Last gen AMD gpus were superior, the radeon 6000 gpus were more power efficient and had often superior performance to nvidia, yet people still bought nvidia. This generation AMD is faster and has more vram for less price at every pricepoint yet people are talking like you "I wish they did the same great job with gpus"

[@SomeUserNameBlahBlah]

@@PineyJustice AMD needs several generations of superior GPUs to cut into Nvidia. Otherwise people won't shift.

[@PineyJustice]

@@SomeUserNameBlahBlah AMD is superior for GPUs at every price point this generation aside from the 4090, and power efficiency isn't a real argument considering how widely ignored it was last gen when nvidia was losing badly at it.

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.

[@I4get42]

I am really hoping that second gen AM5 gets 12 or even 16 core chiplets. It would be awesome to have all those cores on one chiplet, asuming they can keep decent enough cache per core it will make things even better for VM's at home 😀.

[@wryd4sound]

AM5 would either need to run more ddr5 channels or improve their memory controller to sustain higher frequencies, bc otherwise with 24/32 cores you would run into a bandwidth bottleneck so fast

[@kevinj24535]

the leaks tell core count in Ryzen 8000 is the same like Ryzen 7000 but the IPC improvement is the biggest jump in Zen history. APUs (Phoenix) for AM5 has 12 and 16 Zen cores but its an different die with bigger graphic part and as monolithic die.

[@Enilyks_]

AMD have already come out and said that unless there is significant bandwidth improvement to memory like DDR6 they just don't see the need or value in having 16core chiplets mainstream as yet on desktop CPU since there is not enough lanes.

[@Psi-Storm]

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?

[@TorazChryx]

I find myself wondering if Zen4C or it's successors might find a home in an asymmetrical setup like the 7900X3D and 7950X3D, eg. one 8 core chiplet with 3D vcache and one 16 core Zen4C chiplet with less cache but either the same or higher clocks? (I'm aware that we don't have data on how Zen4C would clock in that situation) Making the Performance and Efficiency cores be the same fundamental core design with different cache structures intrigues as a notion?

[@sparkyenergia]

I've said this for a while about AMD's io die stategy. If they really wanted to, there is nothing stopping them from putting a zen 3 compute die onto an AM5 package perhaps for a low cost am5 cpu or going the opposite direction and putting a Zen 4 compute die onto an AM4 package.

[@AliceC993]

I would have to wonder how Zen 4 would be impacted by the relative lack of memory bandwidth on DDR4, if a theoretical Zen 4-AM4 CPU were to exist. Not to mention how exactly it would interface with, say, a B550/X570 chipset.

[@VideogamesAsArt]

while it would work, each core is designed for the IO die it's supposed to be paired with. AMD themselves said they can't increase the core counts (more than 16 cores in consumer desktop) unless the memory bandwidth increases too, since the cores would be data starved. They could do that but the performance would suffer

[@sparkyenergia]

@@VideogamesAsArt Years ago Intel said it would not do more than 2 cores per memory channel. So dual channel, 4 core is what we got. We now have the 13900k with 24 cores total. So I'm not really inclined to believe whatever either company says.

In the next gen desktop 3d chips it would make sense to have a 3d v-cache die and a zen4c die. Specially if they improve the infinity fabrick so the 16 core chiplet can derive some benefit from the other die cache. Won't help in games but it could be both a gaming and productivity beast.

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.

[@jannegrey593]

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?

[@VideogamesAsArt]

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

Any chance you can run a COMSOL benchmark of some kind? I do a lot of COMSOL simulations and they all run on a per core basis and not per thread. I currently have a dual socket 9554 EPYC system with 1.8TB of RAM.

[@Level1Techs]

We have some threads on the forum with comsol it's an odd duck under windows but more consistent on linux .. videovappn I hope

Can you test the 1gb 3dvcache cpu in simulation heavy games vs 7800x3d, like lategame stellaris or factorio. And other cpu heavy titles like 1080p cyberpunk with rt on 4090

So there is theoretically room to move to a 12 x 16 configuration for 196 cores?

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.

I'm sorry if this is a dumb question but what does he mean with "The chiplets are behind the I/O Die" at 04:45? In the official slide from AMD shown at shown at 05:05 they're very clearly not behind the I/O Die..as the corresponding 8x16 chiplets constituting 128 cores are located on top of the substrate at the sides of the I/O Die where they've always placed them. I understand that it's me that's missing something but I'm curious to find out what exactly. So please, pretty please 🥺🙏 I'd really appreciate if anyone can help clarify what kind of chiplets are they employ besides the cores on the Bergamo CPUs, that Wendell is talking about that's placed under the I/O Die?🙏 ✌🖖

[@steffennilsen2132]

Its not about the physical location, its about interface. The IO die is responsible for communicating between the CPU and the rest of the computer, in that sense the chiplets are behind the IO die, think of them as standing behind a door, that is the IO die, and the rest of the computer is on the other side.

@@steffennilsen2132 😆OH!…that..🥴..that just makes A LOT more sense 😁. I for some reason just got stuck parsing it way too literally. Thx 🙏 appreciate it! ✌️🖖

[@justacomment1657]

Hey Wendell, I am following you for a while now.. I do have a interesting workload for you, maybe. We have deployed a vsan cluster with 100GiG wires speed, however our Intel cpus struggle verry hard to go anywhere close to wire. They top out at about 40gig/s. This is already running multiple iperf instances and jumbo frames. I wonder if those amd cpus can handle network IO any better?

would be interesting to see the difference between Ryzen 7950x3d vs these servers.

[@ADB-zf5zr]

@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.

Thinkmate has a configurator for the Supermicro Hyper Server 1115HS-TNR and 1125HS-TNR. Systems (considering cpu/memory only) range from a single-core 9754 w/192GB at $17k to dual 9684X w/3TB at $81k. Drives can easily add $25k or more in larger servers.
