#microarchitecture — Public Fediverse posts

The consumer GPU market isn't in crisis; it's in an undeclared "End of Life" phase. NVIDIA is deliberately starving the AIB supply chain (partners like MSI and Asus) to divert all of TSMC's silicon to AI chips for data centers, where margins are obscene.

MSI just declared 2026 will be a supply nightmare and is cutting production. They're closing the ecosystem. PC gaming and independent builders have become a nuisance for Jensen Huang's balance sheets.

I'm compiling logs and market data for a complete autopsy of this commercial architecture. I'll post the full video on my channel. The era of x86 and affordable consumer hardware is coming to an end under the blows of the CUDA monopoly.

"AMD publishes first Zen 6 document detailing ground-up redesign on 2nm process node — brand-new 8-wide CPU core with strong vector capabilities"

Sounds like they're leaning heavily into 'datacenter' with this one.

Also TIL that CPUs have special hint instructions (called PAUSE on x86) to make spin loops more efficient, which tell the CPU to let other hyperthreads progress instead, and again also improves CPU cache behavior.

AMD Zen 5 Execution Engine Leaked, Features True 512-bit FPU

Giving "Zen 5" a 512-bit FPU meant that AMD also had to scale up the ancillaries [..]. The L1 Data cache has been doubled in bandwidth, and increased in size by 50%. The L1D is now 48 KB in size [..]. FPU MADD latency has been reduced by 1 cycle. Besides the FPU, AMD also increased the number of Integer execution pipes to 10, from 8 on "Zen 4."

#Zen4c: #AMD’s Response to #Hyperscale ARM & Intel Atom
#Bergamo, AMD’s upcoming 128-core server part sets new heights in #x86 #CPU performance. At the heart of Bergamo is #Zen 4c, a brand-new CPU core variant of their successful #5nm #Zen4 #microarchitecture that enables the push toward more cores per socket. Zen 4c enables Bergamo to fit 1.33x the number of cores in the same #SP5 socket and 360W TDP, with identical L1 and 1MB L2 private caches to Zen 4.
