Microsoft Excel 2007
Excel can be a very powerful mathematical tool. In this benchmark we're running a Monte Carlo simulation on a very large spreadsheet of stock pricing data.
The Excel test is peculiar in its results. It must be one of the few situations where Bloomfield's memory bandwidth advantage is seen as even the Core i7 870 can't outperform the i7 920. The Core 2 Quad Q9650 does well thanks to its large 12MB L2 cache, as does the Q6600 with a beefy 8MB cache.
Sony Vegas Pro 8: Blu-ray Disc Creation
Although technically a test simulating the creation of a Blu-ray disc, the majority of the time in our Sony Vegas Pro benchmark is spend encoding the 25Mbps MPEG-2 video stream and not actually creating the Blu-ray disc itself.
Hyper Threading is good for about 4% here, giving the 920 the slight edge over the Core i5 750.
Sorenson Squeeze: FLV Creation
Another video related benchmark, we're using Sorenson Squeeze to convert regular videos into Flash videos for use on websites.
The i5 750 pays the HT penalty, taking another 20 seconds to render our test video than the i7 920. It is still faster than the Phenom II X4 965 BE at a much lower cost. The Core i7 870 comes close but can't beat the i7 975.

biased? they where comparing stock vs stock how can u call that biased, and people is not stupid lol whats that mean?BlueBlazer - Sunday, September 13, 2009 - link
Clock to clock comparison with turbo off..http://www.pcper.com/article.php?aid=776&type=...">http://www.pcper.com/article.php?aid=776&type=...
Phenom II 965 comes in last place, due to IPC differences which is why AMD had to release higher clocked (should I say "overclocked") Phenom II to compete against Core 2 and Core i5/i7 series.

Why compare to a Phenom OCd by 600mhz? The Phenom doesn't do it automatically like the i7ssj4Gogeta - Thursday, September 10, 2009 - link
It's biased because Intel is giving you more features?? The whole point of comparison is to determine which is better. Next you'll say it's biased because it's comparing a Nehalem to a Phenom II.ClownPuncher - Wednesday, September 9, 2009 - link

I'm posting this to an older review, but just wanted to make a comment. I noticed all the reviews that have the Q9650 included, compare it to the Phenom 965... which isn't a fair comparison at all, because the Phenom 965 is running at a considerably faster mhz than the Q9650 is. Plus the Q9650 can overclock much faster with no voltage increase. I would bet the Q9650 is faster than the Phenom 965 at the same clock speeds.
