AMD confirms 12-controller DDR5 Zen 4 CPUs with new Linux patches

AMD’s next-generation EPYC processors aim to deliver insane levels of bandwidth to their users, assuming that AMD’s latest Linux patches are accurate.

According to Phoronix, AMD’s next-generation Zen 4 EPYC processors will feature support for DDR5 memory and up to twelve memory controllers. This is a 50% increase in memory controllers over AMD’s 3rd Generation EPYC processors, which when combined with the benefits of DDR5 memory could enable a greater than 2x boost in memory bandwidth.

AMD’s already taking EPYC in a bold new direction with Zen 4, with AMD offering customers up to 96 Zen 4 cores with Genoa and up to 128 Zen 4c cores with Bergamo. Both Zen 4 and Zen 4c utilise the same basic core design and feature set, but Zen 4c is a density-optimised design that features a reworked cache hierarchy. Zen 4 will be better for some workloads, while Zen 4c will be better suited for others.

Phoronix has stated that AMD’s latest EPYC Linux patches add support for RDDR5 and LRDDR5 memory modules.

AMD’s Zen 4 processors will not just offer customers enhanced Zen 4 cores, but they will offer customers access to higher core counts and a huge boost in memory bandwidth. This will make AMD’s 4th generation EPYC a huge upgrade for many enterprise customers when it launches in 2022.
