WebTomi Aarnio 2236. score:2. OpenCL kernels are almost always memory-speed or pci-speed bound. If you are converting a decent chunk of your data for half floats, this will enable faster transfers of your values. Almost certainly faster on any platform/device. As far as performance, half is rarely worse than float.
