Benchmarks - CineBench 10, VirtualDub and TMPGenc 4.0

CineBench 10.0 is probably the first benchmark that incorporates the SSE4 instructions. As we can see from the score chart below.

At default speeds, the QX9770 scored 3519 vs 3328, a 5% increase when rendering with 1 CPU, with quad cpus, it scored 12492, over 11723 with a QX9650, a 6% increase in performance. When overclocked to 4.2GHz, it gives a 30% improvement over rendering 1 cpu and 27% improvement in rendering X CPU.

Intel QX9650 7 min 20 secs

The two other applications that are said to be SSE4 capable are DIVX 6.7 encoder

In VirtualDub 1.7.2, we used the DiVX 6.7 encoder for 1080HD and encode the Kitesurfing.avi file (provided by Intel). The timings are based on the 2nd run (the first run usually gives a longer time). It seems that the CPU, whether it is overclocked or not did not give  a substantial boost in comparison to the QX9650 processor in this test.

In another test with Windows Media Encoder 9, the difference is more substantial, it shaved the timing to encode the same kitesurfing.avi by almost 25 secs. When the CPU is overclocked at 4.2GHz, the time needed to encode the video drops to 5 min 42s, that is almost 1 min 48 secs faster than the QX9650 (default clk).
