ATi Vs Nvidia (2020)

So a new generation looms and ATi branding is no more so we can't ask ourselves ATi or nVidia again but yet the question remains the same.
Red or Green?
Where do we stand, nVidia GeForce or AMD Radeon?
Or is there a third contender for the crown?

You guys know where I usually stand but I have to admit the Radeon HD7000 series is looking pretty nifty.
Both are shaping up to be absolute power houses so whichever way one goes power seems assured at least this time around.

FIGHT!

I'm really liking the latest development with AMD drivers. 15.7 is gorgeous, and they just released a new one through W10 update.
970 - 390 are two great cards for anyone upgrading, good things for both sides.

nvidias drivers are unstable and inferior to AMD.
I get a slight ghosting on the screen above blocks of colour, had to use paint to verify my screen wasn't ghosting.

Screen flickering is mental on windows 10 also
nvidia doesn't have a problem of unstable drivers, it has a problem of out of spec hardware reacting badly to timing optimisations.

So much drama around the Ashes of the Singularity benchmark, but something particularly nasty came out of it.
Maxwell doesn't support Async Compute, at least not natively. We disabled it at the request of Nvidia, as it was much slower to try to use it then to not.
Ouch.

Short version:
Developers release a benchmark for their game. DX12 performance is much higher for AMD than Nvidia. In fact, Nvidia somehow has lower performance in DX12, which doesn't make sense.
Nvidia blames the developers. The developers say they followed Nvidia's requirements. Developers point to an issue with Nvidia, and offer their help. Nvidia still claims a bug is the issue. Claims AMD favoritism.
Meanwhile, the developers claim they spent more time working on Nvidia's implementation than Amd's, since it had lower performance.

And that's when this comes in:
Curiously, their driver reported this feature was functional but attempting to use it was an unmitigated disaster in terms of performance and conformance so we shut it down on their hardware. As far as I know, Maxwell doesn't really have Async Compute so I don't know why their driver was trying to expose that.
I suspect that one thing that is helping AMD on GPU performance is D3D12 exposes Async Compute, which D3D11 did not. Ashes uses a modest amount of it, which gave us a noticeable perf improvement. It was mostly opportunistic where we just took a few compute tasks we were already doing and made them asynchronous, Ashes really isn't a poster-child for advanced GCN features.
Nvidia PR people also asked the developers to disable some settings in the benchmark.

And to make Ruantec happy:
Our use of Async Compute, however, pales with comparisons to some of the things which the console guys are starting to do. Most of those haven't made their way to the PC yet, but I've heard of developers getting 30% GPU performance by using Async Compute.

Well, oxide do have a page dedicated to explain what mantle is, and the Ashes of the Singularity page has a big AMD logo in the bottom. :p

But it would be nice to see AMD shaking up NVIDIA, competition is always a good thing. Let's see what the future benchmarks will reveal.

Also, nvidia 700 series also gets a huge boost on DX12:

Next year we will have GPU's with >15 billion transistors with more efficient lithography and second gen HBM on Vulkan and DX12 that can leverage the chips better.
We are about to enter the actual age where raytracing is completely doable and it will be glorious, PC!

Am I right in thinking there will be a crossover where Raytracing will require less GPU ability than raster with all the lighting workarounds like voxel GI, SSAO and shadow calculations?
Oh god, I'm running the Dawn demo in 4k and I can smell the golden age of PC.

what I still hate about nvidia, when the hdmi audio is gone and the only way to get it back is to clean out the driver with DDU and reinstall
That's strange, I've been using HDMI for video and audio over five years now and never had that problem. You sure there isn't something wrong with your motherboard or sound card?

I usually deactivated the audio output of the motherboard in win 7, but win 10 figured it out automatically and so far nothing like that ever happened.

no its a very common problem if you google it, but it has only happened once on win7 and a reboot always fixes it until I did a complete reinstall of geforce drivers. I have no idea why it happened to me again on win10, but after several reboots hdmi audio just wouldn't come back so I had to do a complete reinstall of geforce drivers.

All I can remember was I updated geforce drivers and the next day hdmi audio disappeared

Mantle was reworked and integrated into vulkan, the successor of opengl.
TressFX is still being developed and version 3 will come out with the new deus x game, it's also being worked on for unreal 4 and the source code is publicly available.

AMD has the most stable drivers right now for windows 10. Used windows 10 beta and release without a single issue. My 980ti has at least one crash to desktop a day, a window bug, a cursor bug and a drop shadow bug.

Arctic islands will be 2x the performance per watt.
Pascal will have a greater increase than this and maxwell is already the best in efficiency.

If you take fury x, there's over 50 watts saved alone by hbm. Nvidia will gain this advantage as well with pascal and even more savings from mixed precision. I am guessing nvidia will hold back on what they can do to be in line with AMD again. It's going to be exciting to se 28nm die, 28nm is the enemy
