STARS Euler3d computational fluid dynamics
Few folks run fluid dynamics simulations on their desktops, but we've found this multi-threaded test to be particularly demanding of memory subsystems, making it a good link between our memory and application performance tests.

Despite scoring poorly in our memory subsystem tests, the G45 Express turns in the highest score in our Euler 3D fluid dynamics test.

WorldBench
WorldBench uses scripting to step through a series of tasks in common Windows applications. It then produces an overall score. WorldBench also spits out individual results for its component application tests, allowing us to compare performance in each. We'll look at the overall score, and then we'll show individual application results alongside the results from some of our own application tests.

The Pentium E2180 looks to be a perfect match for the Athlon X2 4850e, as all our test configurations produce the same overall WorldBench score. But does the G45 Express differentiate itself at all when we break down the suite's individual test results?

It does in the Photoshop test, where the G45 is more than a minute quicker than the competition. Intel comes out on top in the Movie Creator test, too, although by a much smaller margin. Only 10 seconds separates the field in the Media Encoder 9 test.

Although WorldBench's Office test doesn't mix things up, the standalone and multitasking Firefox tests show Intel lagging behind its rivals. That's not surprising given that WorldBench's Firefox tests tend to favor systems with lower memory access latencies.

We're not surprised to see the G45 Express behind the 780G and GeForce 8300 here, and all things considered, it's really not that far off the pace. The 780G wasn't entirely stable in the DirectX modeling test, which it failed to complete about half of the time. We haven't encountered this issue with older Catalyst revisions, so we can only assume that it's related to AMD's latest driver release.

WorldBench's Nero and WinZip tests tend to favor faster storage subsystems, and the G45 Express takes top honors in both.
