CUDA is so much better that many open-source developers use it despite the fact it requires closed-source binaries to work. CUDA is also significantly easier to implement. They wrote most of the libraries themselves. Nvidia really optimized CUDA for their platform. The reason why they're never chosen is because they lack CUDA, which not only limits what they can do but CUDA is also just so much better. AMD has actually been very competitive in OpenCL pretty much since TeraScale2 and they've done practically nothing to optimize until maybe a year ago. No new developments are done, but bugs get fixed and any changes required to make them work on current OSses are still performed.Ĭlick to expand.Not necessarily.
#Opencl benchmark drivers#
That is why I stated that these companies have put OpenCL drivers in maintenance mode. So there is no interest at AMD to further develop OpenCL.
#Opencl benchmark code#
HIP is structured almost identically to CUDA and there is even a cross-compilation tool that allows HIP code to be compiled on NVIDIA cards (by compiling it to a form that can be fed to NVCC, NVIDIA's CUDA compiler). AMD GPU's are supported for OpenCL 2.x (and thus also 3.x), but internally AMD has switched to ROCm and HIP, which is sort of their version of NVIDIA's CUDA. AMD on the other hand has dropped support for OpenCL on their CPU's completely, which was sort of the point of OpenCL (write compute once and run it on CPU, GPU and any other OpenCL compatible device). So basically NVIDIA still only supports the 1.x feature set, but can call its drivers 3.x because of this. Then the Khronos group (the people who sort of manage the standard and a lot of others too) released OpenCL 3.x, which is not much different from version 2.x, except that all the 2.x features are optional now. No new developments are done, but bugs get fixed and any changes required to make them work on current OSses are still performed.Click to expand.Yes, but what you have to know is that when OpenCL 2.x was released NVIDIA didn't support any of the new features in that version.
Yes, but what you have to know is that when OpenCL 2.x was released NVIDIA didn't support any of the new features in that version. Overall it seems that Intel's best and mot fast GPU A770 seems to switch places with the RTX 3060 in both tests at best (table courtesy videocardz).įunny, nvidia and amd both have opencl 3.0 drivers.
#Opencl benchmark full#
In the OpenCL test, the difference between the A770 and the A750 is again around 12%, which is in favor of the full ACM-G10 model. This is a difference of 10.4% between the two cards. The A76 points on the Vulkan test, while the A750 only got 66609 points. Both cards have been seen on the Geekbench website in an ASUS ROG Z690 Apex & Core i9-12900KS system with both cards installed. It was tested with the A750, which has 448 Vector Engines and 8 GB of VRAM (3584 FP32 cores). The A770 tested is the Limited Edition with all 512 Xe Vector Engines and 16GB of VRAM (or 4096 FP32 cores). Only the first GPU could hint at its actual performance, which may or may not translate to raw gaming power, videocardz noticed. Two graphics APIs, Vulkan and OpenCL, were used to test both cards.
The first benchmark results for desktop cards with Intel's Limited Edition of Arc have been spotted.
