AMD Phenom II X4 955, Phenom II X4 960T, Phenom II X6 1075T, and Intel Pentium G2120, Core i3-3220, Core i5-3330 Processors
Our test method is briefly described here. The scores on diagrams are relative to that of our reference testbed that always scores 100 points. As of 2011, it's based on the AMD Athlon II X4 620 CPU, 8GB of RAM and Palit's NVIDIA GeForce GTX 570 1280MB. Detailed (absolute) results are traditionally provided in this summary.
Phenom II X4 960T is a little faster than Phenom II X4 955 and slower than Phenom II X6 1075T. But all of them yield greatly to Intel processors in this poorly-threaded group of tests. The Ivy Bridge CPUs show similar results, because these benchmarks do not require extra threads or, especially, cores.
Final 3D Rendering
On the contrary, in this thread-hungry test group the middle-range hexacore AMD Phenom II X6 1075T is almost on a par with the low-range quad-core Intel Core i5-3330—not a surprise, really. AMD's lower-range quad-core CPUs can only compete with dual-core HT-enabled Intel processors. Phenom II X4 955 is a bit faster than Phenom II X4 960T, because AMD's Turbo Core is disabled under full load.
Only one benchmark in this group supports multiple threads, so Phenom II X4 960T is a bit faster than X4 955. And 1075T can compete with Core i3-3220. Funny, huh? Considering that it's six cores versus just two.
These benchmarks are similar to those in the final 3D rendering group. Phenom II X4 can outperform only Intel's budget dual-cores, and when Hyper-Threading kicks in, they show quite similar results. AMD's older hexacore processor yields noticeably to the Intel's modern quad-core one, though the latter is the most basic desktop quad-core CPU from Intel.
Compiling tests have always been the strong point of Phenom processors. Two years ago, 1075T easily beat the fastest Core i5, and Phenom II quad-cores were on a par with it. Today things have changed, as you can see.
Mathematical and Engineering Computations
This group of benchmarks is not a lucky break for the Intel CPUs which perform quite poorly. For AMD processors it's just hopeless.
