Synthetic: SiSoft Sandra, AIDA32 and Cachemem
In the SiSoft CPU test we see the 660 just edging out the 560 results, as we would expect for similarly clocked processors. On the memory test, the added L2 on the 660 does improve memory access somewhat over the 560, but the real star here is the 3.73XE running past the entire line of processors when running at the 3:4 memory ratio.
We see similar results here on AIDA32 as the 3.73XE is really showing some impressive synthetic memory results.
Again the 3.73XE is impressive, but the 660 processor comes in well ahead of the results the 560 showed and out runs the Athlon 64 setups as well.
