Radeon Vega 20 Will Have XGMI Interconnect
It's expected that VEGA20, when released, will get a new interface called XGMI, this is a high speed interconnect and can be seen along the ones of NVLINK, a much faster connector. Thanks to a new set of AMDGPU Linux driver patches this was discussed.
XGMI would be a peer-to-peer high-speed interconnect and is based on Infinity Fabric, the unified way to communicate with everything or AMD, even the processors use this. XGMI is basically AMD's alternative to NVIDIA's NVLink for inter-connecting GPUs. The finding was spotted by Phoronix who spotted the new entry in a new AMDGPU Linux driver. They, for now, can be found on the amd-gfx list but will likely be queued via -next for introduction in the Linux 4.20~5.0 kernel as part of their latest Vega 20 enablement work.

if has 4096-bit HBM2 higher clocks on VRAM/GPU and lower power draw, is that really matters now, Nvidia is over 50% higher performance per watt
greetings
Comparing 2 unreleased chips/architectures. Should we laugh or cry?

If that's what AMD has got lets hope it make a huge difference as the GPU market really needs AMD maybe there not interested in high end and hope to dominate the mid range

It can be... gigitty
Looks like SLI/Crossfire is back in a new form
Can it overcome the bad support of CF for games? or only Game Dev can?
Does it Really matter? I am a Huge SLI/CF supporter but the games are just nos supporting SLI anymore, is declining more and more, the only recent title I can think supports sli is FC5 nothing else
my last two rigs were sli but when I moved to the 1080ti I said no more due to poor game support
This feature is mainly for enterprises running deep learning software, and Vega20 itself is also an enterprise focused product which I don't think will be released for the gaming market.
