I have posted several links on the subject previously [1]; here's one [2].
Basically several projects and the codes got pulled into 
GCC-5, where the GPU (processor and memory) resources
are utilized along with the systems CPU and ram for gcc-5.x
compiling and executing of codes.  DDR-5 for many algorithms
will make certain codes very fast to run.

As always more processors and more ram is better. Intel is already
moving higher end systems to DDR-4 on the mobo. Using the GPU
(SIMD) and the DDR-5 ram only adds to the capability of the machines.

If you can afford it, get a mobo that supports DDR-4.
Right now the AMD-HBM Fury-X is the video card with the 
highest bandwidth for a memory buss on a video card, if
you can find one for sale:: limited production right now.

RDMA Remote Dynamic Memory Access is the principal finally available
in gcc....

Game_changer imho.
