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.
Considering the fact that Zen 2 microarchitecture is expected to generally increase performance of CPU cores (especially when it comes to floating point performance), the Rome processors will likely boost performance of servers quite dramatically when compared to existing machines.
This is a breaking news. We are updating the news story with more details.
