Compute

Unfortunately, as I mentioned earlier in my testing observations, the state of AMD's OpenCL driver stack at launch is quite poor. Most of our compute benchmarks either failed to have their OpenCL kernels compile, triggered a Windows Timeout Detection and Recovery (TDR), or would just crash. As a result, only three of our regular benchmarks were executable here, with Folding@Home, parts of CompuBench, and Blender all getting whammied.

And "executable" is the choice word here, because even though benchmarks like LuxMark would run, the scores the RX 5700 cards generated were nary better than the Radeon RX 580. This a part that they can easily beat on raw FLOPs, let alone efficiency. So even when it runs, the state of AMD's OpenCL drivers is at a point where these drivers are likely not indicative of anything about Navi or the RDNA architecture; only that AMD has a lot of work left to go with their compiler.

That said, it also serves to highlight the current state of OpenCL overall. In short, OpenCL doesn't have any good champions right now. Creator Apple is now well entrenched in its own proprietary Metal ecosystem, NVIDIA favors CUDA for obvious reasons, and even AMD's GPU compute efforts are more focused on the Linux-exclusive ROCm platform, since this is what drives their Radeon Instinct sales. As a result, the overall state of GPU computing on the Windows desktop is in a precarious place, and at this rate I wouldn't be entirely surprised if future development is centered around compute shaders instead.

    I've got some benchmarks for you.

    The legend is in Russian, but It's gonna be easy to figure out everything else. The first three is for decode, fourth and fifth for encode (ffmpeg fast/speed preset).

    Just to let you know that AMD's Windows property drivers actually ain't in that good shape. I noticed based on Michael's Linux tests (OGL only for now) that RadeonSI open source how new AMD GPU's actually achieve better results compared to Nv cards with mature property drivers.

    Naturally RadeonSI is also far from optimized for NAVI. Point is there's more to expect from driver optimisations in the future.
    . Best regards.

    Well, AMD is failing - the have no competitive mobile parts - CPU & GPU. How much is the market share of mobile vs desktop these days? In the company I work for, every new hire gets an Intel based Dell laptop and the towers are disappearing all the time. Reply

    If I had a nickel for every time I've heard "AMD is doomed" since 1999 I'd be worth considerably more than I am...;) Reply

    If your count is on par with mine.. likely you'd be able to pay all your house bills for a couple of months! Reply

    I didn't mean to say that AMD is doomed. I meant that way that AMD failed to deliver anything compelling for me - good, competitive, high performance mobile products. Reply

    not yet you mean :-)

    It also needs noting here that OEMs are getting ready to release some pretty impressive AMD mobile setups.. It was mentioned during trade shows over the past month. Their basically going to be hitting practically every sector pretty hard over the coming months... The Ryzen 2700U and 3750H look fairly solid to me.. Reply

    Zingam.. " the have no competitive mobile parts - CPU & GPU " um is amd even launching mobile parts to day ?? nope.. maybe later in the year.. but not yet... Reply

    TF does this have to do with this review? Reply
