Synthetic Performance
When testing with SPECviewperf v10 the Phenom II X6 1075T performed slightly slower than the 1090T and just a fraction faster than the 1055T in the Maya test, no surprises there.
The Phenom II X4 970 was roughly 2fps faster than the 965 which was enough to match the performance of the Core i5 750 processor. The Phenom II X2 560 provided almost no performance gain when compared to the 100MHz slower 555.
The Athlon II X2 265 was also roughly a single frame per second faster than its predecessor while the Athlon II X4 645 was almost 2fps faster than the 640 while the Athlon II X3 445 slotted in-between the two Athlon II X4 processors.
Testing with CINEBENCH R11.5 we recorded the CPU results and found that the dual-core processors including the new Athlon II X2 265 and Phenom II X2 560 all produced very similar scores. The dual-core processors with Hyper-Threading support such as the Core i3 540 and Core i5 650 produced similar scores to the AMD triple-core processors such as the Athlon II X3 445.
The Athlon II X4 645 did well and although it was only a fraction faster than its predecessor it closed in on the Core i5 750. The Phenom II X4 970 on the other hand was faster than the Core i5 750 despite only being a fraction faster than the 965. Again as expected the Phenom II X6 1075T was found sitting halfway between the 1090T and 1055T processors.
Using the WinRAR built-in benchmark we saw almost no difference in performance between these new AMD processors and their older counterparts. In fact, the performance increase was so small that in some of the runs they showed as slower though the average doesn't show this. These slim margins are nothing to get excited about.
