A list of Desktop GPU architectures
UPDATED in February 2017 Some optimisation tricks work really well on one architecture, and are useless on others. And even with better drivers, the older architectures need some help. In other words, it helps to know what architecture the GPU has….
Google blocked OpenCL on Nexus with Android 4.3
Important: this is only for Google-branded Nexus phones – other brands are free to do what they want, and they most-probably will. Also important: this doesn’t mean that OpenCL on Android devices will be over, but that there is a bump…
