I have posted several links on the subject previously [1]; here's one [2]. |

Basically several projects and the codes got pulled into |
| 9 |
GCC-5, where the GPU (processor and memory) resources |
| 10 |
are utilized along with the systems CPU and ram for gcc-5.x |
| 11 |
compiling and executing of codes. DDR-5 for many algorithms |
| 12 |
will make certain codes very fast to run. |

As always more processors and more ram is better. Intel is already |
| 17 |
moving higher end systems to DDR-4 on the mobo. Using the GPU |
| 18 |
(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. |
| 26 |
Right now the AMD-HBM Fury-X is the video card with the |
| 27 |
highest bandwidth for a memory buss on a video card, if |
| 28 |
you can find one for sale:: limited production right now. |

RDMA Remote Dynamic Memory Access is the principal finally available |
| 31 |
in gcc.... |

Game_changer imho. |
