Battlefield: Bad Company 2

The best thing we can say for the A8-3800 is that it wull run this game competently. We're less pleased with the Athlon II X3 455, whose 45 FPS average and 37 FPS minimum doesn't inspire confidence.

Source engine particle simulation
Next up is a test we picked up during a visit to Valve Software, the developers of the Half-Life games. They had been working to incorporate support for multi-core processors into their Source game engine, and they cooked up some benchmarks to demonstrate the benefits of multithreading.

This test runs a particle simulation inside of the Source engine. Most games today use particle systems to create effects like smoke, steam, and fire, but the realism and interactivity of those effects are limited by the available computing horsepower. Valve's particle system distributes the load across multiple CPU cores.

Although the Core i3-2100 has only dual cores, each of those cores can track and execute two threads via a feature Intel calls Hyper-Threading. This test is highly multithreaded, and the Core i3-2100 handles it very well, outperforming even the fastest current AMD quad-core processor, the Phenom II X4 980. The A8-3800 trails substantially.
