Why it matters: The AMD’s Zen series has already made the appearance, especially the Zen-2 based Epyc CPUs that are the most recent ones, the server landscape is much different than before. AMD has also announced that they are going to provide better IPC by swinging the server segment, to provide lower latency and improved performance per watt with their upcoming Epyc Milan and Genoa CPUs.
AMD revealed details about the design of their upcoming project Zen 3 and Zen 4 architectures and also showed the timeline of its upcoming next-gen Epyc Milan and Genoa processors at the HPC-Al Advisory Council UK Conference.
Two years ago, in the server space, Intel captured 99% of the market but now AMD’s Zen architecture and Epyc have proved a turning point for AMD. It has been found that AMD could make progress as much as 10% of the lucrative market throughout 2020 as well as looks to maintain the progress by its Zen 2 Epyc Rome CPUs
The company updates its Zen arch on a yearly basis, according to the latest roadmap they did the same. Milan is in the final stage which suggests that the samples of these will be sent to some close customers.
Milan is likely to boast the Zen 3 arch cores on refreshed 7nm+ node, and till quarter 3 of 2010, it must be entered in the production. Same likely the current generation Rome, Milan will scale upto 64 cores and to be dropped in the same SP3 socket, as well as it seems that the Milan will take advantage of 2 threads per core.
As Rome did, Milan will also use nine-dire configuration with the one I/O die and eight compute dies, but the company might make some changes under the hood by equipping each Core Complex Die (CCD) with 32MB of unified L3 cache.
Further, the roadmap states that Genoa will use the Zen 4 cores and looks to introduce new SP5 platform dropping the SP3 socket. Moreover, Genoa will support the DDR5 Ram memory, these are in the design phase right now and will arrive near 2021.
