Vega 7nm early benches

Seems Nvidia isn't the only one beefing up GPU to GPU communication speeds :

Seems AMD will be unveiling a new high speed communication bus on Vega 20, similar to what Nvidia has done with their new bus protocol, and this one is based on infinity fabric which is the same as what their thread ripper CPU's use to communicate between the active CPU dies, so it's a bus with a 50 GB/sec transfer speed between 2 active dies at least...… Both AMD's and Nvidia's are much faster than using the PCI-e bus, which tops out at 16 GB/sec for 3.0 and doubles for PCI-e 4.0 to 32 GB/sec so that put to rest the need to have a faster PCI-e bus in future motherboards......The heaviest thing one can run given the amount of data involved is a video card by far, and the rest is easy by comparison.

more and more m.2 ssd's will drive that

They'd need to make an interface 4x faster than the current X4 PCI-e used on all M2 drives to max out PCI-e 3.0 and there are cards that support 4 M2's in raid 0 but that isn't exactly cheap by any means, never mind 4.0 PCI-e being twice as fast as 3.0 so the main question is if flash memory can read and write that fast since that isn't much below the speeds of regular powered ram, as my DDR4 3200 ram using 4 channels hits a little over 80GB/sec read and writes but as you know when the power is off, all data on the sticks gets wiped out.


Making Data remain when powered off and do so at speeds 4+ times faster than today's M2 drives can read and write will take some time.
