AMD's Flagship EPYC 9664 Zen 4 Genoa CPU is reportedly a 400W Monster!

AMD's flagship Genoa CPU could be a 400W 96-core monster

It looks like AMD's flagship EPYC Genoa processor is going to be called the EPYC 9664, at least according to the hardware leaker @yukki_ans. If today's leaks are correct, AMD's flagship EPYC processor is going to offer AMD's customers 96 Zen 4 cores, 192 threads, and boost clock speeds that can reach 3.8 GHz. 

AMD's Genoa EPYC 9664 processor reportedly has a base clock speed of 2.25 GHz, and the CPU is likely to have 384MB of L3 Cache and 96 MB of L2 cache. This is 480 MB of combined cache, with each of AMD's EPYC's twelve Zen 4 CCDs having 32MB of L3 cache and eight cores that feature 1MB of L2 cache per core.

The EPYC 9664 features a 50% increase in CPU core count over today's flagship Zen 3 EPYC 7XX3 series offerings. AMD's Zen 4 EPYC processors will also support up to 12-channel DDR5 memory, and PCIe 5.0 connectivity, giving AMD's newest CPUs more memory bandwidth, and more connectivity potential. With 50% more DRAM channels and support for faster DDR5 memory modules, Genoa's going to offer AMD's customers a huge boost in memory performance. Beyond that, this change will also allow EPYC platforms to support larger total DRAM capacities.

With a 400W TDP, AMD's EPYC 9664 flagship will be more power hungry than AMD's existing EPYC processors. That said, the processor's larger core count and other architectural improvements should allow AMD to deliver large enough performance gains to make these increased power requirements worthwhile for their customers. 

AMD has confirmed that they have plans to add their innovative V-Cache technology to their EPYC Genoa series processors, creating Genoa-X processors. These processors will launch after Genoa and give AMD's customers access to CPU models with additional L3 cache. These large caches can be used to accelerate specific workloads significantly, making Genoa-X the best processors available for certain tasks.
