Intel may not be the only chip maker to offer HBM powered server CPUs as AMD is reportedly planning its own EPYC Genoa variants based on the Zen 4 architecture for bandwidth-bound workloads.

The rumor comes from Inpact-Hardware who have reportedly received information from their sources that AMD is planning an HBM variant of its upcoming EPYC Genoa CPUs powered by the Zen 4 core architecture. While we have learned much about the standard Genoa CPUs, this is the first time we are hearing of an HBM variant.
