According to fresh rumors, AMD is planning two different stacks of Epyc processors for launch (sometime in late 2022/early 2023). The first one, codenamed “Genoa” as we’ve heard will feature up to 96 Zen 4 cores (5nm EUV) while the second one will push the count up to 128 cores (twice as much as Rome and Milan). While the former is going to compete in the server and data center segments against Intel’s Xeons, the latter is primarily aimed at the Cloud market where Arm-based chips most notably Amazon’s Graviton, Nuvia, and Ampere have started to gain traction.
According to Moore’s Law is Dead, Genoa will settle for a maximum core count of 96 and instead focus on single-core performance with support for AVX-512 and higher boost clocks as that’s what the competing Intel chips are good at. Genoa should launch in late 2022, and target Intel’s Sapphire Rapids-SP which are going to feature a ton of new features, including PCIe 5.0, DDR5, and on-die HBM memory.
The other platform, codenamed “Bergamo” will also use the SP5 socket but feature an increased core count of up to 128. The plan is to offer compute densities on par with newer Arm-based competitors looking to integrate as many as 200+ cores in future designs.
Meanwhile, there are rumors going on about a new Zen 3 APU based on Global Foundries’s 12nm LP+ node, codenamed Monet. This SKU will feature four Zen 3 cores and up to 256 RDNA 2 stream processors (four Compute Units). These parts won’t come to the mainstream consumer market, and will likely be reserved for embedded devices.
