One correction I would mention is. The latest version of PyTorch. PyTorch 2.0 is moving away from CUDA. For ever increasing AI models CUDA on its own can't optimize for the scale. The frameworks themselves have to be optimization aware. This is why ML frameworks are shifting from the eager mode to the graph mode, which sidesteps CUDA (cuDNN) and provides better performance. Instead of using CUDA, they will use tools like Triton (this is what Open AI's ChatGPT uses) which interfaces directly with Nvidia's NVPTX and AMD's LLVM AMDGPU backends. So CUDA is on its way out and with it Nvidia's software moat. MI 300 will be a monster.

@@peterconnell2496 the bottom line was the APU wasn't that feasible, but now we see Intel & AMD strengthening gfx, while Nvidia are launching ARM CPUs for the data centre. So this memory unification is the direction for high performance. The old APUs were too compromised by cost limits, restricted memory bus, cache; despite AMD having a transparent NUMA in their server CPUs, they didn't have the investment funds to realize the possibilities. A sceptical observer suspects the justifications were rationalisation for a panic reaction to CUDA. IIRC ATI were in trouble, AMD wanted a slice of GPUGP, so the Fusion concept of another VLSI step was born. The problem was Intel had successfully responded to AMD64 and the x2 chips with Core Duo, had bribed the key OEMs and had a voucher system of rebates with Intel Inside that small dealers relied on. So AMD were squeezed from both sides, not able to realise the profit from their real innovations and NOT having the financial muscle to buy an OpenCL counter to CUDA of sufficient quality & application support. AMD were following and trying to catch up; Intel had gone awry with P4/Itannic but commercial power kept them strong. Nvidia meanwhile reaped the rewards of the collapse of competition with their new main competitor having to divert funds away from future GPU designs.

Awesome job covering the mi300 it’s so impressive and beyond anything ever made no one knows how to cover it or even talk about it. The technology is going to make it into gaming consoles. I predict next gen is going to be so integrated the thought of adding ram and separate cards to a pc will feel ancient

AMD is way ahead of the curve vs the competition. They just need someone to market the tech better. They are a true heterogenious system and get better and better every year. Now AMD is sharing GDDR with CPU / GPU and other AI accelerators.

Something I wanted to add: since we don't know the packaging method yet, when I talk about the "interposer" it doesn't have to be a large silicon interposer, it might l be a small "organic interposer" like on Navi31, using TSMCs "Fan-Out" technology.

It's 100% confirmed to be a standard, absolutely freaking MASSIVE (as in it pushes TSMC's max reticle size limits right up to their absolute freaking er.... limit lol 🤣) silicon interposer. 🤷 AMD were originally planning on doing what MI250X did to connect its HBM, which is use a hybrid of a standard interposer ala MI300 & fan-out wiring ala Navi 31, w/ TSMC's "CoWoS-R" packaging, which uses a small silicon bridge + fan-out technology. (Think Intel's EMIB, but instead of the tiny silicon mini-interposer bridges being directly connected on both ends w/ physically die-to-die attached TSV's [which TSMC can now do too, called "CoWos-L"], they're connected w/ less dense fan-out wiring [although still plenty dense enough for HBM3].) But then at the absolute very last minute possible, AMD had to switch to a traditional absolutely gargantuan silicon interposer (aka using TSMC's "CoWoS-S" packaging) pretty much as late as they possibly could due to reliability concerns, thanks to the massive package flexing/warping when kept at its full-fat 750W load for seriously extended periods. Basically, with MI300 having a MUCH larger overall package than even MI250X, the tiny silicon bridges connecting the HBM stacks were simply much more prone to failure than a single massive contiguous silicon interposer across the entire package under the kinds of "100% load, 24/7/365" conditions that are inherently endemically common in HPC/data center land. 🤷

For an example, CoWoS-S/a traditional large silicon interposer is an ENTIRELY DIFFERENT packaging tech than what's in MI300's also CoWoS but rather "CoWoS-R" using MI250X predecessor! ("CoWoS-R" is a hybrid between Intel's EMIB tiny silicon interposer bridges [which TSMC also now has a proper version of, called "CoWoS-L"] & the ultra dense fan-out wiring tech used by Navi 31/2 & Apple's M# Ultra SKU's. Basically think EMIB style silicon bridges but connected on both sides w/ less dense but still plenty fast for HBM3 fan-out wiring vs EMIB's/CoWoS-L's direct chip-to-chip TSV's. They didn't end up using CoWoS-R again on MI300 like they'd originally planned to because of reliability issues w/ the tiny silicon bridges at its full 750W load for truly extended periods, as is the standard HPC/data center usage environment.)

1. Excellent video. I don't follow the data center innovations that closely, I'm more of a desktop gaming guy, so this video was absolutely fascinating to me. Well explained, well segmented. And it's exciting to think about what this will mean for the desktop for the upcoming decade. 2. Before you introduced the 5 new technologies, I paused the video and gave it a quick think of myself. I basically came up with the same categories. Except I came up with "heterogeneous design". In my head that was something that takes the SoC and disaggregates it into chiplets but also includes mixing process nodes and possibly chiplets made by different vendors / foundries. We're not quite there yet. But in my head mixing 5 with 6 nanometers is a part of it. So I basically mushed your "SoC" and "Packaging" category together and added a bit of my own flavor. 3. The classic 'von Neumann' architecture on PC can't keep up anymore. We see this with the consoles, how a smaller, much cheaper design can yield incredible performance. Mid to high-end PCs that cost 3 times more struggle to play the latest console game ports. This is ridiculous, somethings got to change. I'm curious how a next gen PC architecture will look like. Will we still have a modular design, how will cooling look like and will manufacturers be able to agree on a standard in time before consoles make the PC look even more boomer than it already looks to some people? 4. Exciting times ahead.

It's kinda ironic that now that they achieved this complete "fusion", it's not their slogan anymore. But the technology has been a long time coming. Long before their Ryzen comeback, AMD was forced to innovate to stay alive. The design lead AMD currently has is a result of this. Fully agree, exciting times ahead!

Great video, cheers!

Fugaku with the Fujitsu A64FX walked so El Capitan and Mi300 could run. Seriously.

MI300 is something I've been waiting for since I saw the initial HPC chiplet APU patent... The interesting thing is that older CPUs used to remove functions from the CPU die because of limited transistors at 180nm etc... But the biggest thing about it is that I heard some autonomous driving folks say that 2000 TOPs are needed for an FSD experience and since MI250X has 383 TOPS, 8X that is almost 3500 TOPS... AMD can now theoretically provide all the chips for automobiles out of nowhere it seems (NOT!!!)... They can use an edge like appliance with a Pensando front end for network relays for traffic and weather, etc. for a LARGE MAP area, while an upcoming Ryzen APU can do the entire system, including 4K video and gaming... Companies are selling mini PCs with Ryzen and Radeon 6000 that can do 4K30+... Zen4 telco servers can do edge processing while EPYC can stream games and all types of data including AI for predictive routing...

I think you are spot on. Though I would say that another tech to look out for is in-chip fluid cooling. Heat is a huge problem, especially with 3D stacking. Efficient extraction of heat allows for higher frequencies and lower energy use (as heat increases resistance).

The Zettascale strategy is interesting because it pulls you into real world limitations, that is physics, that will inevitable halt performance if we don't invest in new techniques. Like with 3D V-Cache, although is a great solution for more L3$, there are still thermal limits. AMD investing in RnD is a long term goal. And investing and brute forcing into todays technologies like monolithic designs, we'll see in the near future to be unreasonable.

To me, the most memorable part of the keynote in the entire Zettascale race was logic on memory. I can't really imagine just how much you could realistically put on RAM, probably only basic math operations as anything too complex would probably be too costly. But if you can even just do basic math, even just add/substract/jump, it'd be a true revolution. So many basic operations would be loaded off the CPU and live in the RAM. The CPU would just have to send the request and that would seriously take down transfers. You could go from 20 transfers and operations down to something like one CPU -> RAM transfer, operations by the ram, and then RAM -> CPU transfer when done to send back the updated data the CPU wanted. It's truly revolutionary in speed and efficiency. How costly/plausible...don't know. But I find it to be the most impressive thing.

The eight extra "dies" are probably what I could call fillers, not spacers. I don't think they are there to provide any structural purpose, but simply to take up space that would otherwise have to be taken up by the resin used to make the whole package flat. As for the stacking method, I can only make a wild guess. The bottom dies are apparently mostly for I/O, so they could be quite large, given the lack of scaling with I/O. They would then also have a lot of dead space, making TSV's an easy option on that side of the equation. If I had to guess, I'd say they connect to the upper chiplets using the normal connection points those chiplets would have if they sat directly on a package. Meaning the bottom dies replace the substrate as far as the stacked dies are concerned, and use TSV's as needed to connect to the actual substrate for reaching the socket pins. That would make the overall design chiplets on top of active interposers, on top of a passive interposer with HBM at the sides.

Wrong. They are officially & explicitly according to both AMD & TSMC there to maintain structural integrity across the massive chip package, just like OP claimed. If it was just a massive valley of pure in-fill material placed over those areas in-between the HBM3 stacks instead of hard silicon, it would have allowed SIGNIFICANTLY more flex and warping under the package's full 750W power/thermal load, which could EASILY break the RIDICULOUSLY FUCKING FRAGILE like 1100mm² active silicon interposer everything sits on top of. 🤷 (Not break as in "crack it" or anything, but rather cause some of the countless MICROSCOPIC TSV's ["Through-Silicon Vias"] connecting the massive interposer to all of the various chips on top of it to become disconnected.)

Intel's Meteor Lake will also be chiplet based (Intel calls them "tiles") and I'm sure sooner than later Apple & Nvidia will join the club.

There will even be a PCIe accelerator version that's basically 1/2 of a MI300X on a half size interposer & thus package! (2x base tiles + 4x GCD's & HBM3 stacks vs MI300X's 4x/8x, so 152 CDNA 3 CU's w/ 96GB HBM3 vs MI300X's 304 CU's/192GB). Think the new MI210 equivalent to MI300X's direct MI250X replacement.

Imagine a (professional) consumer grade APU with 24+ Compute Units of RDNA 3-4, with 128MB 3DvCache or, on die HBM. Filling a PCIE slot with other expensive silicon could become optional in some cases.

I want to have this monster in my desktop computer...

I say APUs will be the next wave as they are able to perform equal to/better than a console for less money. Small form factor mid range Gaming PCs will be their replacement. I would like to see mobos using dual APUs and shared VRAM style RAM for system and graphics. I really like where they are going. It's what I was hoping for, so I think it will close about the console prediction. Maybe one more "next gen" system from MS and Sony then done....unless they start making pre-built under the name, but they prob won't wa t to deal with that if there is no licensing revenue. Nintendo will probably keep making consoles though, I hope. Anyway my same old ramblings. Thanks for the update!

GPUs are accelerators only used to perform a specific set of operations. CPUs are still needed to feed the GPUs and run the actual programs. For instance if you're doing AI training. You still need the CPU to parse and provide the data to the GPU, and then compile those results into a model. CPUs are really good at executing serial code, while GPUs are good at executing highly parallel code. You need both. And AMD is the only company that can provide best of breed CPU and GPU.

They're not mutually exclusive. A base amount of on package memory could be provided for performance/efficiency reasons and additional memory added-on via either DDR sockets or CXL. I think the main thing preventing it is profit margins; AMD can't sell integrated memory unless they add the large margin that their shareholders expect. System integrators/OEMs don't want to have their costs inflated.

I think AMD wants either take over or participate all main computer components (CPU. RAM, GPU) profits, it would be logical from business point of view, simple basic reason. 3D stacking technology is beyond my imagination, but explanation by expert of how it works can be easy. As amateur I can think if single layer of chip adds some mass over substrate, then making dead electricity conducting areas on ground transistor layer towards vertical space would enable ability to stacked another layer of transistors fuctioning either 2 5D or fully connected. Or rather some kind of placing another layer of substrate at single transistor accuracy in X and Y axis. The real way it is made needs explanation, if I haven't missed its concept in this already scientific publication of upcoming product.

@HighYield

Жыл бұрын

For me, the easiest way to imagine 3D stacking is with the use of TSVs, which are literally tiny copper wires drilled into the silicon that connect both chips. It's like a network of pipes.

It is not only that AMD has a better product than Nvidia but they are also going to use open source software which will be better and cheaper than Nvidia software. It is a win win for AMD. 🎉

Will Nvidia produce CPU?

I think PHOTONICS are THE FUTURE........ why continue pushing electrons around a board and chips where every bit of distance requires more power to get it there... its inefficiency, like you said, will require a Nuclear Power Plant just to run z Zettascale Supercomputer and the building it's housed in.... photons (light) are so much better to do the work with (IMO) although, we do not have a processor that can compute using photons instead of electrons (I think) .... but there has been some progress made in this field. BUT not very much. Not enough to make a difference right now. We still still use the traditional electronic methods with some photonic pieces in the system currently... we NEED to make a 100% photonic computer for it blow people's minds enough to fully pursue it instead of using a mix of both systems.... I'm hoping you've done a video on this already (I JUST came across your channel when this video was suggested to me, but this vid got me to sub... I really like the cut of your jib, sir! lol) if nopt then I hope you can do one in the near future...there is just too much potential with photonics for it to continue being ignored :)

Unless you mean to return to analog, application-specific optical Fourier transforms, I don't see why photons would be better to work with than electrons. Photons still have to interact with electrons to change their phase and direction, and the structures have to be much larger than a wavelength to overcome diffraction. Current wavelengths are in the tens or hundreds of nanometers, so the density would be lower.

Are Nvidia and Apple the last big bastions of huge monolithic chips? Both of those companies seem to have the same attitude to throw money on the problem and let the consumer pay for it. Nvidia and their maxing out chip size for each node. Apple M3 with 3 different design chips reported to cost 1 billion dollars to make. Why did Apple not release a 4-chip M ultra-ultra chip as was rumored for the Mac Pro replacement? Pro machines with 192gig memory are a no-go for many IT pros. (and 256 does not solve it either. 4 chips would at least bump it up to 512 compared to Intels MacPro with 1.5 terra)

Cerebras is banking on wafer-scale chips (entire wafer is one chip) so it can work to have big chips with the right design. You have to be able to fuse off all the bad silicon and/or have enough binning and market margin/demand to make it work. I read on the average nvidia gpu die 10-20% of the silicon is defective. The chiplet strategy is more economical, especially with a simple 2D interposer as on ryzen/epyc. The advanced packaging is much less economical, it would seem easier to do than EUV but if there is any flaw, you are throwing out a lot of chips (no fusing option at this stage). So it really depends on the packaging cost, capacity and reliability as far as how it shakes out in the end.

The stacking of chips was started by Tesla and is used in there cars. This one technique increases processing power and reduces power consumption just by doing that alone. Distance matters.

AMD should no longer acknowledge Intel...as a kick in the face.. Intel deserves it..
