AMD Previews EPYC ‘Rome’ Processor: Up to 64 Zen 2 Cores

[harlan4096]

AMD on Tuesday formally announced its next-generation EPYC processor code-named Rome. The new server CPU will feature up to 64 cores featuring the Zen 2 microarchitecture, thus providing at least two times higher performance per socket than existing EPYC chips.

As discussed in a separate story covering AMD’s new ‘chiplet’ design approach, AMD EPYC ‘Rome’ processor will carry multiple CPU chiplets manufactured using TSMC’s 7 nm fabrication process as well as an I/O die produced at a 14 nm node. As it appears, high-performance ‘Rome’ processors will use eight CPU chiplets offering 64 x86 cores in total, as well as an eight-channel DDR4 memory controller supporting up to 4 TB of DRAM per socket. Besides, the new processor supports 128 PCIe 4.0 lanes to connect next-generation accelerators, such as the Radeon Instinct MI60 based on the Vega 7nm GPU.
