AMD Reportedly Planning Zen 4 EPYC Genoa CPUs With HBM…

Intel could not be the only chip maker to present HBM powered server CPUs as AMD is reportedly setting up its very own EPYC Genoa variants dependent on the Zen 4 architecture for bandwidth-certain workloads.

AMD To Respond to Intel’s Sapphire Rapids Xeon CPUs With Its Own HBM Powered Zen four EPYC Genoa CPUs, Alleges Rumor

The rumor arrives from Inpact-Hardware who have reportedly gained info from their sources that AMD is planning an HBM variant of its approaching EPYC Genoa CPUs powered by the Zen 4 main architecture. While we have uncovered a great deal about the standard Genoa CPUs, this is the very first time we are hearing of an HBM variant.

There is certainly a recurring dilemma of an HBM model of Zen four between partners, but for the second nothing at all seems definitively made the decision on this issue. The company could indeed reserve these a resolution for selected consumers or eventually want a variation with 3D V-Cache .

According to the report, an EPYC CPU with HBM memory is a recurring dilemma amongst AMD’s companions. Intel has by now declared its HBM variant of Sapphire Rapids though individuals chips aren’t expected all-around 2023 (in volume). AMD is reportedly getting ready its Milan-X lineup as an intermediate concerning Zen three and Zen 4 which would dwelling 3D chip stacking technology even though almost nothing is obvious whether the die stacking is dependent about CCD’s or V-Cache (equivalent to future-gen Ryzen Zen three Desktop CPUs).

It is probably that AMD could give Milan-X with 3D V-Cache as a showcase of how the low-level cache can help raise general performance in bandwidth-certain workloads and ultimately scale it up with extra high quality HBM selections when EPYC Genoa launches. The difference in between Milan and Milan-X in phrases of start is around two-three quarters and the identical timeframe can be envisioned for an AMD EPYC Genoa lineup with HBM.

What is absolutely heading to be exciting is AMD’s HBM implementation as they can go with either traditional off-die strategies or a a lot more next-gen 3D Chip stacking tech. Intel hasn’t confirmed what alternative it will use for its HBM integration but they are most most likely going to make the most of their EMIB and Forveros interconnect/packaging technologies to built-in HBM memory on Xeon CPUs. It will be terrific to see both equally businesses give HBM server variants to increase their workload portfolio in the HPC segment.
