Xeon E5645 vs Celeron 3855U

Both Xeon E5645 and Celeron 3855U monothread performance are pretty similar although their multithread performances are very very different. These two models were released in very different times which doesn't explain their performance similarity in monothread performance so we should check if they belong to the same range.
