What it is interesting is that no test used for the IPC increase over Zen4 is 1t. They are all multiple threads, of course there are lower threaded tests (like FC6 - which has a strange behaviour with AMD) and higher threaded tests.
What is "strange" in all that is, multi-threaded performance increase is exactly where I'd put it (and I wrote it earlier in this thread that I expected around 10-15% in that) because nowadays it is mostly limited by thermals and power, which are also consequences of the production process. n-thread is exactly where the N4 to N5 process jump allows it to be. Single thread, I think we have to see the specific benchmarking. But all in all, the performance increase is not stellar, so in the desktop arena competition will continue as today. Server is another matter.
It is not a joke, but it most certainly is a poor substitute for real world performance. Try to run actual code on a real macbook to see.real world performance is always better than synthetic and potentially manipulated benchmarks
open bench is a joke because its real? man, we have user submitted benchmark threads here on the forums, those would easily be as legit... Are you thinking of userbenchmark? the site that is very not legit?
Zen 5 was a jump on the next curve of progress. It could have gone better, it could have gone worse. I think It's normal that they got 16%. The next question is - can they iterate effectively upon that? If Zen 6 can deliver good PPC increase, it means they did something right with Zen 5.
They aren't?Remember that clocks are going down slightly despite the better node.
Base clock is a meme on AMD parts and we're talking 1t stuff anyway.200MHz lower base @ 16c @ same tdp.

at nt fmax
That may be due to architectural differences, not node. They doubled AVX512 throuput, which probably causes 200MHz drop under such workloads.200MHz lower base @ 16c @ same tdp.

Back to the the slide rule or abacus I suppose.
It was also the only Zen to be on time so that was nice.
That can still be made up in later generations?
The problem with OpenBenchmarking is that people misuse it: wrong compiler flags, obsolete versions of SW (for instance some of the benchmarks used to be only optimized for x86 intrinsics/assembly and only got Arm support recently), etc. I basically don't trust the database of results. But I agree the width of applications is great and much more pertinent than other benchmarks such as Geekbench and SPEC.
How so? according to these barcharts, it should be a bit faster than the current x3d. If anything, it looks like in gaming zen5 is around 25-30% faster than vanilla z4 (if we take the same-ish tests of HWU (xmp 6000, stock limits and good cooling solutions) -It seems like the 9950X will still be quite a bit slower than the X3D zen 4s for gaming.
Eh, It's better to just wait for independent results, but I agree that Zen5 seems to be better than Zen4x3d, but I only looked at the games that AMD showed on their keynote.How so? according to these barcharts, it should be a bit faster than the current x3d.

Windows 10 still supported btw, probably the last AMD series that does this.By the way, confirmed that they're using chipset lanes for USB4, not CPU (which was already known but now confirmed)
edit: hmm, maybe I got the wrong conclusion from this info. not sure

Professor! You game too???But at that level of performance, unless there's a strong efficiency improvement or very strong AVX-512 performance, I'll wait for X3D.

I agree, it remains to be seen how the newer wide arch would behave itself in games and light int-heavy workloads. I just noted that it's not all doom and gloom, but I guess the N3x hype flop did not teach some people anythingh, It's better to just wait for independent results, but I agree that Zen5 seems to be better than Zen4x3d, but I only looked at the games that AMD showed on their keynote.
Just a bit. I'm more interested in not having a CPU consume too much while having 16 cores et great ST/MT performance. This eases CPU cooling and reduce the electricity billProfessor! You game too???
Yes. You had access to the same, seemingly official slides which predicted a 10-15% IPC increase, and instead not only propagated unsubstantiated rumors of 30-40% IPC increase, but suppressed the release of said slides by other leakers so you could push your claims, probably for clout.Are you suggesting that I intentionally overhyped Zen5? Are you brain damaged?
Hopefully this means that Zen6 will also be on the AM5 platform. To me there is no reason to upgrade from Zen4 to Zen5.
