I am looking at a dual socket server based on the Intel(R) Xeon(R) CPU E5-2640 v3 @ 2.60GHz
The configuration looks like this.
4 memory channels per socket
DIMMs are 8x32 GB DDR4 2133/1866 modules per socket.
JEDEC says DDR4/1866 peak transfer rate is 14.93333 GB/s. Given that there are 4 memory channels, can I assume a (theoretical) memory bandwidth of 4x15 = 60 GB/s?
None of the benchmarks (single-threaded reads) I have gets close to that, they max out around 9 GB/s.
