As did I, but a little digging shows a STREAM benchmark (on AMD's page)
showing +25% performance of a single-socket Epyc vs. a dual-socket E5-2690
v4 Broadwell system, and roughly 60% better specfp_rate2006 numbers when
comparing socket-to-socket. When I read stuff like this, I feel a
little bit like Charlie Brown going to kick the football, and *hoping* it's
not going to get whisked away by Lucy... but right now, this looks pretty
impressive, especially given the memory bandwidth issues on Xeons on some
Since those are both AMD links, and not independent, take a grain of salt
with them, but I harbor some optimism, and would love to get my hands on
one. We'll see.
