Even though this is mostly simulations, raytracing, "AI" stuff etc., it gives a taste of what we might have in store when more common productive applications will start to offer support. I'm thinking of things like Photoshop, Premiere, DaVinci Resolve, various CADs and modellers, etc.
Especially worth mentioning here is the difference of AVX2 vs. AVX-512 on Zen 4 vs. AVX-512 on Zen 5. Overall, there is still a lot of gain for the "double-pumped" 256-bit on Zen 4, and most of the difference over AVX2 here showcases how much instruction overhead (directly and indirectly) there is.
IPC wouldn't change from software improvements.AMDs new ZEN5 CPUs weren't ready for prime time. They should have waited till the software and new motherboards were "Officially" ready. So now AMD needs to play catch-up because these CPUs should be at a min 10-12% IPC over the previous gen.
ZEN5 suffers from Windows Scheduling issues. The same happened with ZEN4 when they first came out.
Developing a scheduler is Microsoft's responsibility, not AMD's.
But specify what do you mean here; do you expect an optimized scheduler for generic CPU capabilities (like SMT, hybrid cores, etc.?), or one per microarchitecture?
I'm not aware of significant changes which should cause Zen 5 to behave significantly different from Zen 4, are you?
And in case you are expecting specialized schedulers then that's not going to be very sustainable in the long run. A couple of generations down the line, and Zen 5 owners will be "screwed" again, as sooner or later they will either have to drop something or make a hard choice which benefits the newer hardware at the cost of the old.
If hardware really needs this much specializing in the OS kernel, then something is heading down the wrong track. We need more robust hardware designs than this.
Major design issues?AMD did have an opportunity to really give it to Intel and all their major design issues. But nope lol, not yet I suppose.
Are you talking about the issue of voltage causing prematurely worn CPUs? That's not a design/architectural issue at all.
It's not like any of them can observe the other and 6 months later release a product based on those decisions. The major design of Zen 5 was done years ago. They have two or three generations in development at any time.
I think many are just having unrealistic expectations. As I said months ago, it would take a lot to catch up with and even beat Raptor Lake in performance per core. This is not helped by clickbait YouTube channels and rumor sites trying to make up the most exciting and controversial news.
Overall, I'm not so disappointed in Zen 5 as most of the people in here seem to be. There are certainly use cases where it shines, and others where Intel shines. If AMD would get their act together and create Threadripper variants for these very quickly, at least down to 12 cores (8 cores too, preferably), I'd be very tempted to buy one.
