Olympic Ridge wasn't the name I heard for Z6 Desktop. Interesting

8CU RDNA 4 on the iOD for Desktop would be very, very impressive. Basically would turn any Z6 DT CPU into also a G series. With the extra of FSR4 support.
Doesn't make any sense though for Medusa Point to be using the older 3.5 µArch if the desktop package uses RDNA4.

I guess there's also the possibility of that iGPU being used for Zen7 DT too, giving it multi generational ROI.

I think I know why it's that big. The MS requirement for the copilot+ sticker is 40 tops of sparse fp16, right? 8 CU of RDNA4 hits that at ~2.5GHz.

They are probably using the GPU as the AI accelerator. This way they are at least not wasting any silicon on an accelerator that's never used.

As nice as 8 CUs sounds AMD isn't just giving us that on desktop from the goodness of their hearts. Aside from the AI theory, it could make sense if the same IOD is being reused for something else where some GPU grunt makes more sense.

More than likely, AMD is getting more Xtors per $ with Samsung 4LPP than with TSMC N4C. We heard about AMD booking S4nm capacity about a year ago, many speculating that it was for a "Mendocino" like processor. As badly as Samsung is floundering, they are likely desperate for customers.

Looking at the competition from Intel, they will have notably better iGPUs on desktop going forwards. AMD needed to improve there from the paltry CUs they have now. 8CUs of RDNA4 will do nicely for them and finish rendering very low end video cards from NVIDIA and Intel irrelevant, a market that AMD no longer competes in. It should keep them competitive with -H processors on mobile as well.

Here's an idea: How about releasing early RDNA5 silicon with Zen 6 so that it gets into the wild as early as possible and then they can keep fixing the bugs encountered in real world usage and by the time RDNA5 dGPU is ready to ship, the drivers are already fine-wined and ready to go!

@adroc_thurston , please do forward this idea to Lisa. Thank you

Why would rdna 5 be ready for igpus that far ahead of DGPUs do you think?

the opposite.
That makes no sense. Once the CU is done, you just add them up. Fewer CUs should mean less time required for validation and performance scaling optimizations. And people won't come out with pitchforks if the iGPU underperforms a bit at launch. They can always improve the drivers later. Not as catastrophic as a dGPU underperforming.

Integrating the thingy takes a lot of time.
Also there's a lot more to the GPU than just the shader core.

That's really not the limiting factor for GPU validation lmao.

Drivers are easy (well, for AMD and NV. They have the know-how and the established codebase). Hweng is hard.
See RDNA3. Or Blackwell.

Can you please stop making up excuses and just pass my message to Lisa?

She is a lioness. She will get it DONE!

And it's the weekend. She needs a bomb to drop on her team

She's not a hardware overclocker but a fleshware overclocker. Always pushing squishy brains to their limits

That might be very reasonable, yes. A few additional CU do not cost that much area. On Desktop you have more benefits from a bigger iGPU and power draw in case of ML/AI Workloads is not limiting here (not with only 8 CU and >=88W PPT). With 8 CU, also the "DT APU" could get obsolete, which would streamline the portfolio (so no Medusa Point for DT). The gaming performance should match or even exceed mobile Strix Point also in raster (890M with 16CU is barely faster than a 880M with 12CU), which would be a huge uplfit compared to Zen 4/5 DT. Another critical point here is SW support and a bigger iGPU would have an edge here as well over an NPU (not only ML/AI workloads but application acceleration in general).

It will be interesting, if we see any salvage parts and still exceed the 40 TOPS Windows Copilot requirement. RDNA4 is capable of hitting very high clock speeds and it seems N48 gets mainly held back by power limits. So it depends, what the process node (N4C or SF4) and further clock rate optimizations can deliver.
- 8 CU @ 2.5 GHz = 40 TOPS (INT8 dense)
- 6 CU @ 3.3 GHz = 40 TOPS
- 8 CU @ 3.3 GHz = 54 TOPS

A bigger RDNA 4 IGP being standard for Zen 5 Ryzen DT not only would be able to meet Copilot+ standards but would also help AMD Radeon marketshare on PC and weaken Nvidia market and mindshare among casuals I'd think.

Imagine you buy a Ryzen 10700X and out of the box you get a iGP capable of 1080pFSR4 gaming. Would basically render useless a purchase of a entry-level Nvidia dGPU for many users.

Sorry for being a party-pooper, but iirc MS explicitly requires these TOPS in the form of a dedicated NPU, otherwise I'm sure at least AMD would've preferred to go with some hybrid solution in Strix instead of adding that fat NPU.

I think that requirement is a bit silly, but we're talking about MS here.
