Office XP and Photoshop
PC World Magazine's Worldbench 5.0 is a Business and Professional application benchmark. The tests consist of a number of performance modules that each utilize one, or a group of popular desktop applications to gauge performance.
Below we have the results from WB 5.0's Office XP SP2 and Photoshop 7 performance modules, recorded in seconds. Lower times indicate better performance here, so the shorter the bar the better.
Though this is the fastest score we've ever recorded in the Office XP test module for World Bench, the QX6850 is afforded less than a 2% gain over the QX6800 with a 6 second overall advantage. To be honest, Office applications really don't stress any of the processors we tested here.
The WB5 Photoshop 7 test shows a similar scale but the scores ended up even tighter. In short, when it comes to Photoshop 7, a 3GHz dual-core Core 2 chip is nearly as fast as a 3GHz Core 2 Quad. And the 1,333MHz FSB of the new QX6850 didn't offer any tangible performance increase. In the future, we hope to migrate to World Bench 6, though it is still in the beta stage. Newer versions of Photoshop with better multi-threading capability are incorporated into that release, so we hope to be able to exercise these new high-end processors more then, once the benchmark suite is finalized.
