Megatasking: pushing it to the limit

Here's the graph you've seen before, detailing the DivX-encoding results. Nothing new here.

You may well want to do more than run a single application at one time if there are four cores on tap.

We've now we've added a 1080p QuickTime clip into the fray, being rendered at the same time. What we're seeing here is how much the DivX encoding time is being compromised by the additional computational load presented by running the high-resolution clip on a looping basis.

Sitting somewhere in-between the Intel Core 2 Quad Q9550 and Q9650, the X4 955 BE does well enough not to be embarrassed even by Core i7.

Here's the same test but with the high-resolution Enemy Territory: Quake Wars running, looped, in the foreground. The observation, above, is reinforced in this benchmark.

And the ET:QW benchmark results with the DivX in the background. All quad-core chips do exceedingly well here, and it would be difficult to visually pick a winner, no matter which chip was in the socket.
