Massive AMD Zen 5 IPC gain of 25%+ reported as leak alleges increased L1 cache and revamped L3 cache for Ryzen 8000 CPUs

[Lakados]

On newegg best selling cpu first page, none of the AMD has more than 8 cores, despite some being quite expensive (like the 7800x3d) and I suspect a lot of higher than 13900k sales are more because of the bigger cache, better bin than wanting 8 more E-core, not many people would sacrifice the first 12 core being any slower to have more of them in that price range-segment, 16 cores model appear on page 3.

They would know the demand, I would imagine that for 24 core cpu to be worth it, in many case you would want more than 2 memory channel to not starve those extra core and you go into threadripper pro-epyc segmentation territory issues even more than the high core count started to do.

Starving core of memory bandwith is such an issues that they add CXL memory to system with 12 channels

I really do dislike that AMD and Intel have left us starved at 2 memory channels. It is becoming a very noticeable bottleneck, but they have to protect their 4+ channel workstation market. Because any of the i9 or Ryzen 9 CPU’s with 4 memory channels would cut their workstation sales in half.

I'd certainly buy a 24 core Ryzen with 4 memory channels.

What workstations? Those have 8 channel memory and AMD pretty much abandoned Thread ripper.

Random side question, do you think Skylake-W is still relevant then to get an all p-core system with 4 RAM channels?

You're getting older. Im going through same thing.

I am. Other then playing around with the new Zelda on PC emulator for an hour I haven't played a game on it all year. PS5 is collecting dust also. I never even finished GoW Ragnarok. I just can't find myself to care anymore.

I feel that way about new titles. I still find myself enjoying old games I'm replaying or hadn't tried yet. For hardware I can't be bothered to upgrade without a reason, which I have few without games which require it.

I already did - It was Zen2 threadripper. Still happy with it too - both of those systems are running great for what they do.

I'm hoping Storm Peak is good.

Oddly enough I got back ~into~ gaming hardcore this year.

No, it has the memory channels but the rest of the platform is too slow by modern standards so you just move your bottleneck.

There may be some edge use cases Im not thinking of though.

Agreed with both of these. It's... better than x299, but not good enough to be super competitive yet.

I can't because I have too many other projects going on. Plus there is no Titan Fall 3 still yawn... Diablo IV might be fun. Waiting till June 6th to grab it and start playing. Might give me a few hundred hours of fun. Don't laugh but I'm thinking about fencing in an acre and getting a pair of pet donkeys. Yeah I'm getting older.
