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 ahve the XFX 5700 non XT model. Refence cooler. It was less so noise that was the issue but more the revving of the fan. It was never sure on a speed to settle at. So I went into Wattman and locked the fanspeed to 30% (~1700 RPM) for anything above 50C across the board. Clocks hover between 1650 - 1700 MHz during long gaming sessions. Temp wise it settles in at about 85C and is a bit quieter than my old RX580 ASUS Rog Strix OC model. I wish they just shipped it like than rather than leave me to tweak it myself. Reply

    Nice review and very good video cards from AMD, finally!

    If you want to compare RX5700 and RX5700XT please check this link:

    There are results from 22 games in 3 resolutions from few computer services (anandtech too). To translate just use google translate on the right sie of site.

    @Ryan , please flesh this out; it's been months since the review. Reply
