Amddddddddd

ya'll saw the video ?? it's sooooooooo fast. ONTOP of power efficiency, and won't burn down your house/motherboard.. 

Keep things short,   13% ipc increase, + 800mhz to 5.7ghz from 5950x (last gen)

net +29% performance, across all core, 

NO glued on E cores to cheat benchmarks like Intel.



Mobile ryzen 4 is going to be interesting, because at lower clocks they can get +76% power efficiency.    That's gonna make for some Really REALLY fast thin and light laptops. 

At the highest clock, they're still pulling about +35% power efficiency on the 5nm node.


These numbers are currently NOT using the 3dVcache which will be a separate release later. We can probably expect a healthy 5-10% in workloads once that comes

I'll will be waiting until real units are shipped out - I never trust the charts.  Also personally more excited about Raptor lake from Intel - should be impressive.

They had other slides showing the actual benchmarks they used,  AMD's pretty legit.

Not long after the initial Ryzen release I said this (AMD with DDR5) would be my next upgrade - possibly the furthest in to the future I've "planned" anything.  Still no dates or details on the APU the plan solidified into but with these kind of performance/power improvements I could probably just get the cheapest one and make my first completely silent computer with my trusty fanless 1050ti.  Assuming DDR5 actually exists to buy that is (it didn't when I last looked months ago)

Apparently, these Ryzen CPUs support some AVX-512 instructions. I wonder if the benchmarks took advantage of them.
Intel tends to not have AVX-512 support in non-server processors, and the 12900K is no exception.

the reason they pulled avx512, is because it's not really a consumer workload.

I also have a feeling, avx512 probably causes alot of instability for intel at the insane power envelop they're pushing to compete with amd. 

Dolphin benchmark maybe.  the nintendo emulator, other than that, you just don't see it.
