I mostly get SSE2 work units on my Sandy Bridge Intel Core i7-2600 CPU (which has SSE3 and AVX1 but not AVX2). I sometimes get SSE3 units too and I have seen AVX units once or twice as well, but the server seems to prefer sending me SSE2 work.

Why I get SSE2 work on my SSE3/AVX CPU? How can I force SSE3 or AVX work? Is the AVX app happy with AVX1 CPUs or does it require AVX2? (Haswell New Instructions)

Are the SSE3/AVX work units equivalent in terms of science output to the SSE2 units? Or do the SSE2 units implement different scientific computations that cannot be done by the SSE3/AVX apps?
