BackHi, I'm using OpenCL on Windows 10 and a Radeon RX580 card (8GB VRAM). I tried to allocate two buffers with 4GB to use in a kernel, but at this size, all I get is 0.0. I double checked address bits and it is 64 and th... Why I can't use buffers with 4GB?
BackHello. I see many messages regarding wrong results that AMD RX 5700 cards producing. Those results are consistent (being WRONG) enough to pass statistical validation. Why AMD being long-term and knowable corp... Broken OpenCL drivers for RX5700
