For the question about the Intel iGPU: My example is CPU only. You can check what GPU is being used via Activity Monitor > CMD + 4 while ffmpeg is doing it's thing.ĭon't worry about that, I reconstructed some parts by myself. I would expect the Intel UHD to do really well while working with H264/265. I checked wayback machine in case there was an archive, but it wasn't saved. Posted by: Not sure if I can do anything about that myself. The GTX1050 performs very simular ot GTX1080Ti (but having just one core) The GTX1080Ti has two cores for video encoding and so it's possible to encode two videos at once at full FPS. When using AMD hardware the additional option "-gops_per_idr 1" should be used. CPU encoding (hevc and h264) performs better in MacOSX than in Windows usage of AMD or nVidia hardware seems not possible via ffmpeg in MacOSX hevc_videotoolbox is clearly inferior in quality at low bitrates, NVidia GTX980Ti: 146 FPS (x2) (hevc_nvenc) Intel Graphics UHD 630: 143 FPS (hevc_videotoolbox) Please test your gpus, too and post your results here! Thank you.Įspecially I would like to know the benchmarks of Radeon Vega 64 (or at least Vega 56). The tool ffmpeg (used by a lot of GUI applications like Avidemex or Handbrake) is very useful for this purpose:īenchmarks for transcoding into HEVC (h265) Codec on a 15-inch MBP 2018 with i7 2,6GHz:įfmpeg.exe -i file_example_MP4_1920_18MG.mp4 -c:v hevc_nvenc -c:a copy -quality quality -b:v 3M -bufsize 16M -maxrate 6M outhevcNvidia.mp4 nVidia, AMD and Intel provide frameworks and own codecs for this. Now you know how to check that your graphics card is stable and fully functioning, how to validate performance numbers to make sure your GPU is up to spec, and how to gauge the baseline performance of your hardware for future upgrade comparisons.An important feature of GPUs is the encoding/transcoding of videos. There you have it! You’ve graduated to GPU benchmarking pro. More advanced gamers can use software such as Fraps or OCAT to manually benchmark performance of games that don’t have a built-in benchmark, but this will require more time, testing, and figuring out a repeatable testing scenario to avoid potential scene-to-scene variance. As a bonus, if you upgrade your graphics card or other PC hardware, you can re-run the benchmark and you’ll know exactly what gains you’ve netted. Shadow of the Tomb Raider is a favorite of mine because you can easily see the frames per second performance that you’re getting in each scene, giving you a good indication of how the game will run overall. The results overview from Shadow of the Tomb Raider‘s built-in benchmark. (Check out our GeForce RTX 3080 Ti review to see some common ones, or the list of games with built-in benchmarks at the always fantastic PC Gaming Wiki.) Thiago Trevisan/IDG The first order of business here is to make sure your graphics card can run without shutting down or displaying any weird graphical glitches, so you should allow it to run Heaven for at least 30 minutes, to allow the GPU to get up to temperature.Īnother very fun way to benchmark your GPU is to use the automated benchmarks built into many games. It’s free for personal use and runs a loop of a graphical environment that really utilizes your GPU. The first program we’re going to use is Unigine Heaven 4.0. That can mean a dead card, but in many cases you’ll get what are called “artifacts”-basically imperfections on the image, flickering, or even pulsating colors. It’s rare, but sometimes a graphics card can be defective from the factory. Now that you know why you should benchmark, it’s time to get into the how.
