...and Alain said the Intel graphics
driver for Windows includes this too.
Yes, and this GPU is particularly good at bcrypt. In my tests using global memory a HD 4600 performs at 561 keys/sec. Given that HD 7970 is 35x faster than this GPU, this is 19.6k for a comparable high end Intel GPU. It is a pity a high end Intel GPU don't exist yet.

Alain
