Opencl benchmark windows4/30/2023 ![]() ![]() These numbers have a different unit and thus the decimal in a different place but same general rule, if they are 4,500 or above, you have PCIE 2.0. This time they are labeled "Host to Device" and "Device to Host". If you have the correct CUDA driver installed it will launch and again you are looking at the bandwidth transfer numbers. This will only work with Nvidia cards, if you have an AMD card you have to use the other 2 methods, or just look in System Profiler, as it is typically correct about AMD cards. The 2nd way to see your actual PCIE speed is to install the correct CUDA driver and then download CUDA-Z. The final number is overall memory bandwidth on your GPU, it is not always accurate. If you are stuck in PCIE 1.0 speed, these numbers will be in the 2 or 3 region. If your card is running at PCIE 2.0, these numbers will both be 4 or higher. Under "Bandwidth Transfer Speeds" there are 3 numbers, the top one is CPU>PCIE>GPU and the second one is the reverse. But all you really need to see are the numbers on the right when you first open it. Note that the actual benchmark won't run correctly, it will be capped by your screen refresh rate, typically 60 Hz so you will get 60 fps. ![]() One way is to use the "Oceanwaves" OpenCl benchmark. In OS X it is a little more difficult to see the actual speed. When you run the little "system stress" tool you will see the card jump into 2.0 speeds. In Windows it is easy to confirm this using GPU-Z. This also applies in Windows when you use Bootcamp. In fact, the 5.0 speed on both Kepler and Maxwell cards (GTX970/980 Titan-X) functions perfectly on both 3,1 and the newer 4,1/5,1 systems. We spent a little more time trying to find the cosmetic part but eventually gave up as it wasn't worth spending additional time on. When we went to find the 5.0 speed for Kepler cards (GTX680/780/Titan, etc) we discovered how to turn on the 5.0 speed, but also discovered that the functional part and the cosmetic part were 2 separate things. With the Fermi cards, (GTX470/480/570/580) the bytes that turned on the 5.0 speed also changed the number in the System Profiler. And they don't typically share that info. No server restart is required.When we write the roms for our cards, we have to reverse engineer things that only Apple and Nvidia know. The hardware acceleration is available immediately for media playback. Select a valid hardware acceleration option from the drop-down menu, indicate a device if applicable, and check Enable hardware encoding to enable encoding as well as decoding, if your hardware supports this. Hardware acceleration options can be found in the Admin Dashboard under the Transcoding section of the Playback tab. QSV uses a modified (forked) version of VA-API and interfaces it with libmfx and their proprietary drivers (list of supported processors for QSV).VA-API is a Video Acceleration API that uses libva to interface with local drivers to provide HWA.Jellyfin supports hardware acceleration (HWA) of video encoding/decoding using FFMpeg.įFMpeg and Jellyfin can support multiple hardware acceleration implementations such as Intel Quicksync (QSV), AMD AMF and NVIDIA NVENC/NVDEC through Video Acceleration APIs. ![]()
