This was predictable when Yee showed that there is a regression in 128 bit op latency and RPCS3 uses pretty much only 128 bit encodings of AVX512 ops.ouch, you guys seen that the 7950X performs better in the PS3 emulation than the 9950X? In the TPU review.
Well, I don't think it is copium to say Windows sucks. But new CPUs should be able to run even garbage software faster. That's the whole point of new CPUs.So the copium and hopium that we currently have is that its three things:
Not enough memory bandwidth for those CPUs, not redesigned IOD results in higher latency, and Windows being Windows, as usual?
Right? I may consider a 9600 as an upgrade for a ZFS file / Plex server but… I don’t think I’ll be replacing my 5950x with anything Zen5. Although it will be interesting how things improve over the year with AGESA and Windows Scheduler improvementsLet me help those still suffering from copium/hopium. Let it go. Todays reviews have completely killed my desire to upgrade from my Zen 3 riggy. I have made peace with that.

JayTwoCents of all the outlets did an analysis of this and provides a fix.stupid core parking feature
Nitpick: Geometric Mean and Average and Median are not the same.When 16% is the average, there should be just as many results over 16% as there is under 16%.
This is close to the penalty of accessing the other CPU ram in an 2S system, very weird, since io die is the same it shouldn't have changed.Core-to-Core latencies more than doubled!?
Core-to-Core latencies across CCD boundaries more than doubled!?

WTF is going on here?
But even in Linux, it's concerning that the 9900X is beating the 9950X in some benchmarks. That should NOT happen. Either the extra cores are getting membw starved or hitting power/temp limits.Across a very large test suite, an 18% performance improvement while using 3.5% less power is a very solid generational improvement. No category of benches saw less than like 12% improvement (gaming not tested). Linux users rejoice, I guess, you got a good upgrade, lol.
What does the cache optimizer driver have to do with a non-X3D CPU???JayTwoCents of all the outlets did an analysis of this and provides a fix.

Screenshot from Bilibili in 360p, sorry for the bad clarity.
It seems like performance uplift is there, so why is the avg application performance showing single digit uplift according to Techpowerup?

Not sure about driver, but I remembered that AT tests the CPUs with JEDEC memory, so the IO die might be in some deep sleep mode that disables the GMI links to secondary CCD, at least I hope so. This is like first gen 32 core Threadripper-grade latency chasm, it'd be absolutely pointless to buy 9950x3d if this thing is not fixedI'm guessing it's related to the new core parking driver which is turning off the cores on 1 CCD.
they should call it just Zen4+, like Zen1 and Zen1+y AMD insists on crapping their hardware launches

No, in many cases it's Zen 4 minus minus.they should call it just Zen4+, like Zen1 and Zen1+
