SuperPI 1.5

Most users were impressed by the Super PI results when the first Core 2 Duo processor was announced. With the QX9770, the Super PI 1M score is what users use as a guide for comparing system performance.

With the QX9650, we ran the processor at default and it scored 15secs to finish the 1M SuperPI Test. When we overclock it to 4GHz (445 x 9), it slashed down to 11 seconds. This is all done in air cool environment. Using the QX9770 (3.2GHz), it completes it within 14.7secs. When overclocked to 4.2GHz, it completes within 11 secs.

Conclusion

In terms of raw performance, the QX9770 is faster than the QX9650 in most of the tests done. This is especially the case in Cinebench 10 and windows media encoder 9 test. As for GPU performance, it didn't seem to boost that much as the applications are GPU bound in nature. At lower resolution, we can see a performance improvement.

With a TDP of 136W, it is important to have adequate cooling for this processor. Using Easytune 5, we monitor the CPU temperature at idle. It registers 32 deg Celsius. After running Cinebench 10, the temperature rises to around  46 deg Celsius. You can see from the task manager the cpu utilisation of each core during the rendering of the image using all 4 cores are at 100%.

The QX9770 extreme processor iis the 2nd processor that uses the industry 45nm and new SSE4 instruction set capability. We have seen the performance improvement in SSE4 enabled applications like Cinebench 10. Thus, if you are the person who goes for video encoding, editing, this processor will definitely slice down the amount of time taken to complete the job. With utmost performance levels that can't be matched by it's competitors, I am sure the QX9770 is able to do better when more applications are SSE4 enabled.
