AMD Giving Up on CrossFire with RX Vega

THU31 · Aug 1, 2017

Multi-GPU tech should have died a long time ago. One of the dumbest ideas in the industry, causes nothing but problems for consumers and developers. Just awful.

From what I have seen, IF in the new CPUs can use the PCIe lanes, i.e. they are "repurposed" when for example you put in a second socket, IF also seems to run around 20-25% faster over the same interconnects.

So what would happen if, hypothetically, Vega has IF capable end points to its PCIe? Can for example the Vega and an AMD CPU a) enable IF over the PCIe connect immediately giving the aforementioned bandwidth increase and then possible b) becuse the GPU is now hooked into the IF "switch" of the CPU, all the cores and RAM now have direct access to the GPU and vice versa? No imagine c) more GPUs are connected the same way and all of them can see each other's HBCC over the IF the same way the CCXes of the CPU communicate ... or something like that.

I can see the new APUs doing this but they can be hard set to IF as no PCIe is needed.

I've had dual cards for years now. Notably had 4 GPU's in the form of the 295X2's that I had in crossfire.

When I first got them they are an absolute nightmare, there's no other way to describe it. But after complaining directly to one of the guys high up in AMD I was given an unreleased driver that fixed the issues I had and was shortly released to the public.

Since then they had released driver after driver that improved no end of things.

I'm now running 2 x 1080Ti's after I expected Vega to be released in January. Depending on what we get in future I will always run the best GPU system that is available, and if it's not crossfire or SLI then it can only mean that we are going to be looking at some majorly powerful GPU's coming out!

MCM and Navi, its all going to be one package with a bunch of superglue.

Boooooo on you AMD, taking the fun away from us multi card users.

It was a driver solution (like SLI). AMD wants a hardware solution (through Infinity Fabric).

It needs to be a hardware solution if it's going to scale.
