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.

Not surprising, AMD slides shown infinity fabric between CPU, APU and GPU.

Will be nice if this connection can finally show multiple gpu's as if they where one at a hardware level eliminating the need for software implementation in multi GPU.

Not enough to make 2 cards into one. Same issue as with nVLink. But likely good enough to do massive linking of 2 GPUs on one PCB... similar to connection between 2 CPU sockets.
But I would rather seen MCM solution, there you do not need to pretend or overrides.

...and I can bet the connector won't cost 80 euro either.

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

For gaming, probably not.. but Vega is also used in datacenter products and in those applications it matters big time.

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

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

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.
