AMD's Zen 4 EPYC CPUs will be massive

Thanks to the Serve The Home forum users 111alan, we have gotten our first look at AMD's SP5 CPU socket, the socket which will be the home of AMD's 4th Generation EPYC processors. These CPUs will be powered by AMD's new Zen 4 CPU cores, which will be available in Genoa (Zen 4) and Bergamo (Zen 4c) flavours with maximum core counts of 96 cores and 128 cores respectively.

AMD's SP5 CPU socket and 4th generation EPYC CPU platform will feature several major upgrades over today's EPYC platforms, supporting 12-channel DDR5 memory (an upgrade from 8-channel DDR4 memory), PCIe 5.0 (from PCIe 4.0), and processor TDPs that reportedly extend as high as 400 watts. 

With their Zen 4 series of EPYC processors, AMD will be delivering customers higher CPU core counts, new Zen 4 cores, faster PCIe connectivity, a 50% increase in memory channels, and a significant uplift in memory bandwidth through the use of DDR5 memory. AMD's EPYC Genoa and Bergamo CPUs/platforms will represent a huge generational performance uplift over Milan series products.

AMD has also confirmed that their Zen 4 Genoa and Bergamo processors will use 5nm lithography, promising higher levels of power efficiency, performance, and transistor density than AMD's current-generation Zen 3 CPU designs. AMD has also promised that their Zen 4 EPYC processors will be CXL complaint.

AMD expects to launch their Zen 4 EPYC processors later this year, delivering to the enterprise CPU market several major upgrades. With more memory channels and faster DDR5 memory modules, AMD's next-generation processors will have access to insane levels of memory bandwidth and larger per-CPU memory capacities. Add on higher core counts and more performant Zen 4 CPU cores, and it looks like AMD's Genoa series processors will be impressive.

If AMD follows the same productization path as Zen 2 and Zen 3, AMD is also likely to launch Zen 4 based Ryzen Threadripper Pro series processors in time. That said, these processors will likely launch long after the company's Zen 4 Ryzen and EPYC CPU product lines.
