#AMD #EPYC #Bergamo Launched 128 Cores Per Socket
Given the popularity of 2U 4 node chassis on the market, this will make a 2U4N platform a 2048 thread machine or one with 1024 threads per U. AMD’s approach is straightforward. It is trading cache size for core density in this generation. The #Zen4c core is 35% smaller than the #Zen4 core, largely from reducing cache sizes and optimizing the footprint around that.

#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.
