A better CPU helps when it's the CPU holding back performance. GPU's are usually the limiting factor at 4k with current high-end CPU's so I wouldn't expect much uplift from an improved CPU at 4k. (At least not with current gen GPU's)

Well this is ideal. will jump on the 5900 with v cache equivalent to replace my 3700x sometime next year. Will give me a good few years with my am4 whilst I wait for am5 to mature.
The game being shown is Gears of War 5. It should really go without saying that you'll only see an uplift in CPU-bound scenarios though. A CPU upgrade doesn't magically make your GPU faster. More faster is always more betterer though. There are plenty of (often) CPU-bound games out there. Far Cry 6 just released and is one. Far Cry 5 was actually one of AMD's examples shown as having one of the biggest gains from the extra cache.When she did this presentation for the 3D V-Cache what game was that being shown in the video and what resolution and gpu was she using for it ? Same for the slides later they don't state GPU or resolution used..
Because if that is 1080p or worse 720p only and on a 6900xt, I'm a bit worried at higher resolutions the real uplift is a lot less than her 15% average better performance. Where going from 3000 zen2 to 5000 zen3 was a real 19% uplift due to IPC. Anyone have any info on the examples she used and what resolution and GPU was used ?
Thinking of something similar, need a GPU first, that might be more difficult!
All these game CPU IPC measurements only make sense in non-GPU limited situations. There is almost nothing a CPU can improve to add FPS when GPU is holding everything backzen2 to 5000 zen3 was a real 19% uplift due to IPC
Yeah the 6800 I bought in Feb for £799 is now looking like a bargain all things considered (vega 56 sold for just under £400), This VCache CPU should allow me one more GPU on the AM4 platform assuming prices get reasonable come the end of 2022.
AM5 is also next year, around Q3So this news seems to have largely gone unnoticed, so far.
AMD has new AM4 based CPUs with extra L3 Cache (which makes use of 3D chiplet technology) planned. According to AMD, the additional cache amounts to an extra 15% performance boost, vs current Zen 3 CPUs.
"There will a Ryzen product in 2022 that goes into socket AM4 with 3D V-Cache" - AMD spokesman.

If it can keep up with Alder Lake's single core performance, and presumably has upto 16 CPU (large) cores, I think this could give Intel a run for their money. Since Alder Lake CPUs won't be cheap, I expect neither will these 3D V-Cache CPUs.
Later on in 2022, we will likely see Rembrandt APUs, which I suspect will be similar to current Zen 3 APUs, but with RDNA 2 graphics, and maybe improved L3 cache.
EDIT - Ok, seen it now...Unnoticed? There's a 15 page thread on it.
Nah, it's pretty clear that Alder Lake will beat current Zen 3 CPUs, if the IPC rumours are correct. I don't think Intel will be 2 generations behind...The most relevant question is how close can Alderlake get to current Ryzen 5000 and under what scenario.
Intel are playing catch up.

Isn't AMD is planning a big little design with Zen 5 though so it can't be that bad?.It’s really not. Alderlake is somewhat of a series of half fixes, pulling together parts that have previously struggled and failed as stand alone products.
The Gracemont Atom cores will have poor IPC but better power efficiency than Rocket lake.
The Golden Cove cores will be fast in 4 thread workload but very power hungry in multithread. Orchestrating the Gracemont and Golden Cove clusters will be a huge challenge. Leveraging the full processing power of the whole chip will be impossible.
