Zen 5 in Strix has same L2 size and same L3 per core as desktop.Because of what you wrote before using L2 size as a reason to differentiate cores. 🤷
They're both 2c effective.and the FADD latency is higher.
If we are to believe measurements done by Alex Yee and David Huang only Granite Ridge is able to do 2c under specific circumstances http://www.numberworld.org/blogs/2024_8_7_zen5_avx512_teardown/#fadd_latencyThey're both 2c effective.
I know what mysticial said.If we are to believe measurements done by Alex Yee
Yes. Why wouldnt it be?
Yes with cutdown AVX-512 to save die space
Zen 5 in Strix is far more different than RPC compared to GLC if anything.
It's not only the lack of 512-bit wide datapath, the vector PRF for 128- and 256-bit operations is smaller and the FADD latency is higher.
I am getting lost in the hazards, do you mean the scheduler hazard that adds 1 cycle latency to ops that are supposed to be 1 cycle only or is there some otherwise undocumented FADD specific scheduler hazard that prevents 2 cycle FADDs to be used every time? As according to all official info on the former, it shouldn't apply to FADD as FADD is anyway is at least 2 cycle op.I know what mysticial said.
Strix is also 2c effective and has the same scheduler hazard.
Was just trying to explain what I think Tup3x had in mind.Zen 5 in Strix is far more different than RPC compared to GLC if anything.

Another YT review, very interesting results with tuned 9700X with windows 11 updates and Core Isolation disabled (vs tuned 7800X3D)|

Isn't the latency issue just for CPUs with multiple CCXs? The 9700X is only has one CCD, so it wouldn't be affected.AMD did say they will fix the core latency issue so hopefully more performance yet to be unlocked
10 October, (If my leaks are correct) I will fire up my Turin and give you some info !The lack of Zen5 turin server stuff sucks... All you keep enjoying these toys
I want 64 core or more leaks, cause this is boring... HAHA
When did they say this? Link??AMD did say they will fix the core latency issue so hopefully more performance yet to be unlocked
If true, that's great for the people getting 1 CCX cpu's. But it doesn't make the 9950X with core parking mechanisms and thread prioritization schemes more attractive than a 7950X.AMD did say they will fix the core latency issue so hopefully more performance yet to be unlocked
And did anyone check if core parking helps?If true, that's great for the people getting 1 CCX cpu's. But it doesn't make the 9950X with core parking mechanisms and thread prioritization schemes more attractive than a 7950X.

But why tho? There were plenty PBO Benches at Release Day, which showed the same 10% Uplift too.I'm surprised the extra power gives it so little. It's 50% more power for about 10% more perf. Absolutely not what I expected.
Well I was suspecting that the 8 core was seriously starved and would show more than 10% after the boost.But why tho? There were plenty PBO Benches at Release Day, which showed the same 10% Uplift too.
It's more than in the last generation. The 9700X gets +6.56% with the higher power limits, compared to just +4.14% between 7700 and 7700X.I'm surprised the extra power gives it so little.
