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.

The 790FX's slight advantage in memory subsystem performance extends to Euler3d, where the nForce 590 SLI falls a little off the pace.

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.

That's what you call a dead heat, folks. Let's see if any of WorldBench's individual application tests can tease out a meaningful performance difference between these two chipsets.

WorldBench's multimedia editing and encoding tests show slim, but consistent advantages for the 590 SLI. The biggest disparity comes in the Media Encoder test, where the 790FX falls 16 seconds behind.

Results are considerably closer through WorldBench's office and multitasking tests. The 790FX steals four seconds in the Firefox test, which has traditionally favored faster memory subsystems.

3dsmax rendering also favors the 790FX by four seconds, but the nForce 590 SLI is a hair faster with the DirectX test.

The performance delta between the 790FX and 590 SLI nearly grows to double-digit-seconds in WinZip, with the 790FX again finding itself trailing.
