I think that the AVX capabilities with Gracemont have been greatly improved.
Here are some sources, but we should know for sure in a few months:
That doesn't mean AVX is significantly better than Skylake. It's identical to Skylake.
L1I cache is bigger because likely it better feeds the dual cluster decode. Skylake has the uop cache, in addition to the 4-wide decode.
L2 cache is bigger on Gracemont sure, but the reason middle-sized L2 caches exist in CPUs like Skylake is because it fills the gap between the super-fast but tiny L1 caches and slow but large L3 caches.
The Load/Store units are enlarged every time Intel increases vector capabilities, and Skylake's L/S capabilities are 4x Tremont. Even if Gracemont has 4x Tremont, that just makes it equal to Skylake not better.
In nowhere in that chart shows that Gracemont is better than Skylake, nevermind for AVX!
EDIT: specifically, the 11900k scored 69% of what the 5950X according to Anandtech. Golden cover is said to be 20% faster, but let’s say it is only 10% faster…
You are looking at the wrong data. It's 69% of
5900X. To compare to 5950X you have to search for 5950X. It looks like it's 58% of 5950X. That's a long ways to go.
You are also saying that Gracemont and Golden Cove hybrid will work perfectly with
no overhead.
I am not saying it can't happen but extremely skeptical considering having two way different cores work together is happening for the first time on Alderlake. In Lakefield it set ST for Sunny Cove and MT for Tremont. And it still had minor issues.
You are saying in the Windows world, being complicated as it is Intel will get it perfectly right in the first time implementation? That with tens of millions of applications, and settings, and Windows being notorious for crappy implementations and bugs will get all working no problems whatsoever.
