AMD has announced the release of its 4th Gen Epyc Genoa-X processors, packing up to 1,152MB of L3 cache per chip. Like the Ryzen 7 7800X3D, you have a standard Zen 4 CCD with an additional 64MB of L3 V-Cache stacked atop each CCD. For the 96-core variant with 12 CCDs, this adds up to a whopping 1.1GB of L3 cache with a price tag of $14,756.

All Genoa-X CPUs have 128 PCIe Gen 5 lanes and 12-channel DDR5-4800 memory. The 16-core Epyc 9184X has a base clock of 3.55GHz and a boost of 4.2GHz. It features 768MB of L3 cache and a TDP of 320W, with a price tag of $4,928.
The 32-core Epyc 9384X has a base clock of 3.1GHz and a single-core boost of 3.9GHz. It packs 768MB of L3 cache and a TDP of 320W. It has a sticker price of $5,529. At the top, you’ve got the 9684X with 96 cores and 102 threads. It runs at a base clock of 2.55GHz and a boost of 3.7GHz. It comes with 1,152MB of L3 cache and a TDP of 400W. The MSRP is $14,756, 2.6x more than the 9384X for three times the cores and 50% more L3 cache.
The Epyc Genoa-X family slides into the same SP5 socket as Genoa and Bergamo. Like their V-Cache Ryzen cousins, they require improved cooling solutions due to the denser packaging. These cache-rich CPUs are best suited for scientific and engineering workloads, which are more memory bandwidth bound. Workstations specializing in fluid dynamics, CAD, modeling, and simulation can also benefit immensely from the extra cache on these chips.
