If Sandra uses AVX in the MM Benchmark, that's not strange. Thuban doesn't have AVX and all benchmarks using it are 10 times slower.

Why do you think that AVX is so much powerful than SSE? Thuban Core and BD module can execute same number of raw FLOPS. AVX and SSE are vectorised packed FP instructions. BD module can execute one 256-bit AVX which contain 4DP FP operations, same as two 128-bit AVX or SSE. In some cases 256 AVX can be faster, but how much? Two times...

So going from 3.1Ghz to 3.6Ghz do these 2 CB scores seem to be inline with reality?

CB scales perfectly with frequency. 3.6/3.1*5.24 = 6.08. Something is wrong here with this results or frequency of CPU's isn't accurate. Actually I think that is much lower than CPUz's readings.
