For this benchmark we ran all the above applications and measured the time it took Sony Vegas 7 to complete. All four cores on the Quad FX system were at 100% load during this testing.
On our custom mega-tasking benchmark we found that the Intel quad-core processor was faster with and without a full load. The Quad FX system didn’t do badly, but under load it was half a minute slower. When it comes to a benchmark that takes five minutes to complete 30+ seconds is significant.
