#AMD #EPYC9845 Makes For A Persuasive Upgrade With Performance & Energy Efficiency Review
EPYC 9845 is AMDs top-end SKU for 400 Watts or less that allows for 160 dense cores per socket compared to the 128 core EPYC 9754 Bergamo. Effectively the same power level and 25% more -- and better (#Zen5C) cores.
Simply upgrading BIOS and swapping CPU withouta memory upgrade and any increased power/cooling requirements while achieving 1.36x performance is a very persuasive upgrade.

Went down a rabbit hole on AMD's new Epyx server processors Interesting engineering on the small scale to get that many cores in the package Zen6 looks like it will double the cores
Still wondering about the latency between all those CCDs and task scheduling

An interview with #AMD's #MikeClark, Father of Zen — 'Zen Daddy' says 3nm #Zen5 is coming fast; also talks compact cores for desktop
AMD expands its Zen 5 architecture. Unlike Intel, which has to reduce clock speeds when its processors run #AVX512 workloads, AMD says these powerful instructions will run at the same clock speeds as standard integer operations. Clark also expanded on how the company achieved that feat and said that its #Zen5c cores can also run full AVX512.

#AMD unwraps #Ryzen #AI 300 series ‘#StrixPoint’ processors — 50 TOPS of AI performance, #Zen5c density cores come to #Ryzen9 for the first time
Flagship Ryzen AI 9 HX 370 has 12 cores and 24 threads that operate at a base of 2.0 GHz and a peak of 5.1 GHz. However, as you can see in the block diagram and listed in a branding slide, the chip has four standard #Zen5 cores and eight density-optimized Zen 5c cores on a single monolithic die with #RDNA 3.5 #GPU and #NPU cores.

#AMD Previews “#Turin” #Epyc #CPU, Expands Instinct GPU Roadmap
The 5th Gen AMD EPYC processors are built atop #Zen5 and will come in designs up to 192 cores / 384 threads per socket! Presumably the 192 core processors will be leveraging #Zen5C cores.
The top-end #Ryzen9000 has 16 cores and 32 threads and runs at 5.67 GHz turboed up, and the Zen 5 cores are averaging 16% more instructions per core than #Zen4.

#AMD Submits #EPYC #9005 "#Turin" #CPU Family: Up To 192 Cores & 500W TDP
5th Gen EPYC family were revealed a while back and included at least 20 SKUs based on the #Zen5 & #Zen5C core architecture.
Top SKU is #EPYC9845 (160C/320Th)
And #TurinDense EPYC Zen 5C: 192 Cores, 384 MB L3 Cache (+50% More Cores / L3 Cache Versus Zen 4C)
AMD EPYC Turin servers is expected to debut later this year after the formal launch of Zen 5 & Zen 5C architectures for the desktop and client PC
