Is AMD the better choice if someone is interested in VR?

[Profoundsoup]

This is what Ive heard from most people, is this basically true? Its because of Liquid VR

[,,,,,,,,,,,,,,,,,,,,,,,,,,]

lol no? How would it be better? The core count won't make a difference because it's not legitimately 8 full cores. Oh yeah... CPU or GPU?

[comicsansms]

What do you mean AMD?
Do you mean CPUs? or 

Do you mean GPUs? or

Do you mean both?

What topic am I posting under? Liquid VR is what im talking about

Well, this has been posted in the graphics card section, so...

If you don't know anything about the competition, the ones you do know about will sound the best obviously....

 

 

Wait for more competitors products to arrive before you jump on a product like that.

Im asking because its what ive heard. Just want to learn more.

I'd say google Nvidia's VR, Google Oculus's Next VR headset, Google Valves VR

Compare and rejoice that its getting closer and closer

I'd say yes right now as Crossfire continue to scale far better than SLI due to it working over the PCIe slot instead of the low bandwidth bridge. That may change however if single GPU with far more power than the current ones come out on Nvidia's side-lets be honest, SLI may work but it outright sucks.

Is crossfire really that much better than SLI?

Yep. So far the scaling can go right up to 99%-pretty much 4 way Crossfire with a card such as the FuryX, Nano or Fury is actually worth it. With Nvidia each additional card gives greatly diminished returns.

Async compute is one of the reason why AMD GPUs get good rep from VR developers which Nvidia GPUs is currently lacking.

...the results are quite similar.  Bioschock infinite is a 100% increase on both, and the 980 gets a better benefit from SLI compared to crossfire in BF4.

All I know is based on comments from the likes of David Kanter who has spoken DIRECTLY with oculus devs regarding performance in vr.

amd cards have significantly faster context switching and can better handle concurrent graphics/compute workloads.  Basically, the rendering for vr sounds like it's relying MORE on asynch compute and preemption than standard dx11 games, and that is where amd excels and nvidia currently fails hard.  Also, according to him one of the ways nvidia got power consumption down so much in maxwell was by removing "almost all of" the scheduling hardware that allows better context switching on the fly rather than having some master command and control in the driver based on more predictable gameplay.  That predictability is less in vr, you shift you head quickly and you need to recalculate a lot of graphics/compute effects and again, nvidia is reportedly a LOT weaker here.

 

GCN is aging well, even that increased power consumption due to not stripping out the additional hardware schedulers was actually NOT in vain, that power savings on maxwell came at the cost of gimping future performance.

 

Not a problem from an nvidia point of view, better to force the fans to keep buying new cards at a faster rate since they turn rotten and stale faster due to the short term design of the architecture.

I actually found a concise summation of nvidia VR performance from a man named Joe on the internet.

Assuming AMD actually has four Fury X's to sell. I'm not sure where you even buy one Fury X today.

[Bloodyvalley]

Honestly, you should just look at some benchmarks. Benchmarks never lie.

390 or above should work for liquid VR!
