Didn't AMD promise to solve both with HSA, which should allow (integrated) GPGPU cores to share all system resources with the rest of the CPU?
- misja111 11y agoYes, HSA was designed as a solution for these problems. It looks like a good solution, however as far as I know there is not any hardware platform implementing the HSA standards yet. Also Intel is unfortunately not part of the HSA Alliance.
- markus2012 11y agoIt seems AMD's Kaveri CPU implements HSA. Some HSA benchmarks from AnandTech: http://www.tomshardware.com/reviews/amd-a10-7800-kaveri-apu-efficiency,3899-5.html http://www.tomshardware.com/reviews/amd-a10-7800-kaveri-apu-... Note: the tests seem to use OpenCL and while they mention, "Looking at the HSA-based results..." I find it strange they are comparing the numbers against an Intel Core i3. It might be more interesting to compare OpenCL HSA vs OpenCL non-HSA.
