Discussion [HWUB] Nvidia has a driver overhead problem. . .

I'd think that if AMD was sitting on the patent for a significant amount of time before the development of DXR, Inline Ray Tracing would have been a part of DXR 1.0 instead of joining over a year later as a part of DXR 1.1.

Discussion [HWUB] Nvidia has a driver overhead problem. . .

RT hardware didn't go into consoles because of the Turing launch but they might have gone into them because of the Turing RTRT plans. Given how long it likely takes for a API like DXR to be cooked up, the other involved parties would have been in on Nvidia's RTRT plans for Turing a good deal of...

Discussion [HWUB] Nvidia has a driver overhead problem. . .

I don't know if RTRT was always the plan for the new consoles. The patent for AMD's RT hardware solution was filed in December 2017, that's just months before DXR was launched and well after Turing was designed. Honestly, a the relatively late addition of RTRT hardware as a feature requirement...

Question 'Ampere'/Next-gen gaming uarch speculation thread

Are you sure? I could be mistaken but I lurk Beyond3D and RealWorldTech forums a lot and I've seen "tape outs" explained numerous times, tape out leaks are commonly discussed and the discussions always to refer to tape outs and getting silicon back as very separate things.

Question 'Ampere'/Next-gen gaming uarch speculation thread

Has Kopite clarified that as their meaning? I mean those are two very different things. I know of other "tape out" leaks that were clearly leaks of the actual tape out, the original Ampere/GA100 tape out leak for instance. That seems so fast though, I've always heard it's like six months from...

The "Ampere" A100 Whitepaper: https://www.nvidia.com/content/dam/en-zz/Solutions/Data-Center/nvidia-ampere-architecture-whitepaper.pdf That's a rather dramatic improvement in TC performance, it will be interesting to see what they end up looking like in the consumer GPUs down the line.

Question DLSS 2.0

The DLSS 2.0 presentation from GTC 2020. https://developer.nvidia.com/gtc/2020/video/s22698 There are some examples in there of how DLSS can at times produce a closer to "ground truth" image quality than even native resolution.

Question DLSS 2.0

Right, but as a concept and regarding the developmental work, it seems MLSS/DLSS was very much "invented" by Nvidia. Also, looking over the DirectML papers and presentations I can find, Nvidia's collaborations and contributions during it's development dwarf any other hardware vendor. DXR is...

[ Digital Trends ] Radeon Image Sharpening competes with DLSS

It's going to depend on the engine. Most game engines aren't really set up properly for ideal NN training yet. This is probably why the quality of DLSS is varying so much between games so far. This along with the lack of DirectML support seems to have signifigantly gimped DLSS on the quality...

Windows NT supported a host of RISC ISA's and Intel was pursuing Itanium for the long term. AMD kept x86 alive, kept it relevant and their cross license with Intel made x86 effectively a duopoly. Then Intel and AMD's deals with Microsoft and OEMs killed IBM, Dell and HP's early 2000s efforts to...
