videocardzAMD shows off Radeon RX 480 running Doom at 1440p/144Hz

[VirtualLarry]

One possible reason I would buy an RX 480 GPU, is if it's basically a 390X, but with a 280X's DP Compute capability. Because somewhere between the 280X / 7950 / 7970, AMD nerfed GCN's FP64 capability. And some BOINC projects really need FP64. So... I'm still rocking a pair of 7950 cards, and not Hawaii-level cards.

So, anyone know how RX 480's DP compute compares to Hawaii / 290X / 390X?

I can understand hoping for something like that, but expecting something like that for less than 1/3 the price is just hilarious to me.

Remember you can buy 3 rx480s for the price of a GTX 1080 and also have a lunch with the left over money.

Yep, the 90% of 1080 performance (dx12 or otherwise) sounds more like build it up / tear it down NVidia propaganda.

People who can only afford a $200 GPU can't afford to shell out $600-$800 for a VR unit. Bringing VR to the masses is a myth, when the masses can't afford it and software companies aren't in a hurry to write games for it.

What about people who get a VR set as a gift or impulse-buy one and only notice during first play that their PC (example: core i5 3570 with gtx 670) is a little bit older than they thought? Should they be forced to spend another 350$ just because?

An increase in TAM also means that VR manufacturers have a broader audience, something that is needed to bring prices on their end down.

Have you guys actually played in it yet? I'm just writing this between breaks in holopoint and let me tell you VR is absolutely going to revolutionize gaming as well as (mark my words) exercise.

most of us who follows new techs knows. I personally just don't want to be an early adopter 😀

I bought a 3D Vision setup a few years ago. It looks absolutely amazing when games are built for it, or at least not built against it. Now, it's hard to find any game that supports it well enough, and at no time did the masses think it was good.

The masses do not have to use a properly running VR game/app to go on and on about how bad it is. Sad but true.

AMD says they designed Polaris for efficiency - that's 99% chance it will have lowest possible FP64 compute

It lowers the cost of the total package. Besides, we're only on gen1 early adopter hardware and if gen1 is successful enough, we should see some updated models next year at lower price points.

You're looking at it incorrectly. You're thinking that the primary purchase is the gpu and the secondary purchase is the VR.

It's the other way around. I *had* to have VR because it's goddamn amazing. I honestly don't want to spend more than I have to on gpu unless it dramatically adds to my VR experience, and, as of now, it doesn't: a 200 USD card will serve me just as well as a 600-700 USD card. I really don't care about gaming in 2d/monitor much because frankly I honestly don't think a single good game has been made since Quake 3/QuakeLive.

When I upgrade to 2k or 4k VR, I'll upgrade my gpu.

Give it 4-5 years and we will see but right now it's a joke and not worth the time and money and expecting the masses to be excited about it right now isn't there.

If you're thinking about buying hardware, you're right, and it's a totally personal and subjective decision.

If you're talking about stocks, you're wrong. The stock market will discount VR growth before it reaches saturation. If VR is a ten year growth story it will probably be fully discounted in 5 years or less because, as you say, in 5 years the writing on the wall will be clear enough for anyone to see.

I think so too. You may think I am joking but once the Porn industry delivers a VR experience, it's on. Internet broadband was very much accelerated early on by the help from the porn demand.

Education, learning, porn, traveling, etc....VR have a wide interest rate.
its not mainstream but when it starts to get there anyone here will one day think, never saw that coming, oh wait I did 🙂

The Nerfing started at Hawaii.

Tahiti is 1/4 DP

Hawaii is 1/8 DP

Fury is 1/16 DP

I believe NV's gaming cards are 1/32 DP and Polaris may end up 1/32 DP also.

AMD's SP don't have separate FP32 and FP64 units like NV's designs. AMD's FP64 implementation is via a robust hardware scheduler that enables the FP32 units to double up and process FP64 workloads.

Hawaii Firepros for example, is capable of 1/2 FP64 ratio, same as GP100.

For efficiency SKUs like Polaris, I would guess the scheduler and supporting registers to be nerfed (not on-die) for efficiency so it cannot do that at a high ratio.

Games don't use FP64 so it's not useful to have it for gaming SKUs. With SM6 in DX12, games may even use FP16 for a massive performance gain for hardware capable of fast FP16 throughput (GCN and GP100).
