Samsung Purchases $20 Million Worth of AMD MI300X Data Center GPUs for AI Development
Samsung Electronics has gone with Team Red and purchased $20 Million worth of AMD Instinct MI300X GPUs for its AI requirements.
wccftech.com
And DDR5-6400, along with a few other features. I think it was necessary since they went +50% cores. While desktop Zen 5 didn't increase the core count, it is disappointing that AMD made no change to the desktop IOD at all to enable higher Infinity Fabric and memory speeds.
MI325X should do well with it's memory capacity. And with the roadmap they're targeting, AMD is clearly putting a lot of resources towards AI GPUs now. From what I've read, that department has the highest resources and engineers allocated to it at the moment (Not a surprise).
While the IO-die is the same, they did upgrade the official memory support from DDR5-5200 to DDR5-5600

Is MI325X primarily used for training? I might have missed it but did not see any inference benchmarks in the presentation.
No, all AMD Instincts are Inference first but now they're starting to claim it's good for training too
edit: was inference before training on presentation too

Why did they only show training numbers vs competition?
The post you quoted literally has inference numbers
ediit: might have been after you quoted but regardless they were there almost immediately)

AMD trimmed down some CoWoS capacity due to uncertainty around MI325X demand, NVIDIA immediately picked up the spared capacity.
Here's Your First Look at a Delidded AMD Ryzen 7 9800X3D CPU With Next-Gen 3D V-Cache Tech
AMD's Ryzen 7 9800X3D CPU has been delidded, revealing the next-generation of 3D V-Cache technology innovations for gamers.

If this is true, it's really interesting. The CCD with the cores is stacked on top of the 3d v-cache. I guess that might be why they've enabled overclocking. Basically the heatsink is closer to the CCD, and in theory less likely to cook the 3d v-cache. Could be a really interesting cpu launch, just from a tech perspective.
It also could have impacted all those changes seen by High Yield on the Zen5 die shot, the tighter packed cache saving die space and the smaller TSVs.Here's Your First Look at a Delidded AMD Ryzen 7 9800X3D CPU With Next-Gen 3D V-Cache Tech

It seems so simple and obvious... now, when you think about all the advantages it provides.
I wonder if there is additional complexity to the packaging/assembly process because that is the only obvious potential downside I can think of.
It looks to me that this arrangement is going to be quite a bit more complex because generally the CCD has more pads, so by reversing the stacking it either the CCD will have to go through the 3D V cache chip or directly through the TSVs.
As for its advantage I can imagine that CCD requires more power so it's better to be closer to the heat spreader. Currently some of the power limits on the X3D chips are there because they don't want to fry the cache chip.

AMD is now working on their Neural AI denoising solution.

Neural Supersampling and Denoising for Real-time Path Tracing
Read our research for a neural denoising and supersampling technique, with the aim of achieving real-time path tracing.

It very much is simple and obvious as people have talked about it before, and they're still not even fully taking advantage of things yet, or at least taking things to their logical conclusion(of what is currently possible, at least). If you make putting a cache chip underneath standard, you can remove all the L3 from the CCD, which makes up a significant portion of the die. This gives a lot of playroom in terms of what to do with the CCD. You could shrink it heavily, you could widen the architecture massively, you could add more cores, you could reduce transistor density to improve thermals and clockspeeds, or obviously any combination of these things.
You could even add more cache or perhaps use an even lower density process for the cache chip(though I think TSMC has limits on compatibility currently?), since you're not having to worry about it being too big and covering up logic or anything.
Honestly, this being third generation of chips since Vcache was introduced, I'm a little disappointed they haven't gone this route yet.

AMD Q3 2024 is up, revenue: $6.82B, up +18% YoY, data center is massively up, client is up, embedded is down, and gaming is massively down. Q4 guidance is a bit cautious.
- Data Center: $3.55B, up +122% YoY, and up 25% sequentially.
- Client: $1.88B, up +29% YoY, and up 26% sequentially.
- Gaming: $462M, down -69% YoY and down 29% sequentially.
- Embedded: $927M, down 25% YoY but up 8% sequentially.
