Default LLR performance on Core1 / Pentium M

I have just noticed that running LLR on Core1 / Pentium M hardware is more efficient with CpuSupportsSSE2=0 than with default SSE2 enabled. In my particular example for k*2^n-1, where k<300 and n~600000 time to complete every candidate is 1730s (SSE2) vs. 1580s (no SSE2) - 8,7% improvement.
I wonder if the same rule applies to A64 architecture?
