AMD’s Zen 2 EPYC Processors will offer up to 64 Physical Cores

During their “Next Horizon” event in San Francisco, AMD has officially confirmed that their 7nm Zen 2 EPYC processors will offer up to 64 cores and 128 threads per CPU socket, delivering a 2x increase in server density over their 1st Generation EPYC processors. 

AMD has previously confirmed that Zen 2 will be socket compatible with their existing EPYC CPU platform, making it no surprise that their 2nd Generation EPYC processors will offer the same 8-channel DDR4 memory setup as their 1st Generation counterparts. 

In SPECfp, AMD has claimed that their 2nd Generation EPYC processors will offer a performance increase of around 2x when compared to their first generation offerings, a staggering increase today’s EPYC processors, setting up AMD to capture market share from Intel in the high-end datacenter market. 

This performance increase will come through AMD’s use of TSMC’s 7nm manufacturing process and the company’s Zen 2 core architecture, which is discussed in more detail here. AMD has also confirmed that their Zen 2 EPYC processors will achieve their high 64x core count by using eight 8-core CPU dies.    

With their 2nd Generation of EPYC processors, AMD plans to deliver a 2x improvement in performance per socket and up to a 4x increase in floating point performance per socket.
