Charlie Demerjian of SemiAccurate has written an in-depth analysis of the 7nm 64-core 9-die AMD EPYC "Rome" server processor. He hypothesizes over the real world performance potential for the processor versus benchmarks by analyzing the chip's design features. He explains why the 14nm IOX chip didn't need a shrink, and how the design choice will speed up production of the processor. He articulates how doubling the instruction widths internally for the new Zen 2 cores leads to a 2X FP performance increase per core and a 4X FP increase per socket. Many other revelations about the new "Intel killers" can be found in the article. AMD has full transparent memory encryption, can secure VMs from the host, and many other useful things that protect users in the real world. Better yet they are enabled with a BIOS switch and have a tiny overhead. Officially there is now more space for keys so you can support more encrypted memory VMs per box. The other big box to check is Spectre mitigations are now rolled in to the core but Meltdown and L1TF/Foreshadow are not. Why? Because AMD wasn't affected by either one and never will be. Patching can work but to be immune from the start is always a better choice.
