Battlefield 3 is the latest installment in the Battlefield franchise released in 2011, and is based on the Frostbite 2 engine, which is DirectX 11. In order to measure performance using this game, we walked our way through the first half of the “Operation Swordbreaker” mission, measuring the number of frames per second using FRAPS. We ran this game at 1440×900, minimizing all image quality settings, disabling both anti-aliasing and anisotropic filtering.

A8-3870K vs. Core i3-2105

You can’t run Battlefield 3 on the included Intel CPUs because it is a DirectX 11 game, and these CPUs are DirectX 10.1.

However, even though the CPUs from AMD are DirectX 11, they can’t run this game at a playable frame rate, even with all image quality settings minimized.

When we added a Radeon HD 6570, the video performance of the A8-3870K increased 62 percent. With this video card installed, this CPU was 29% faster than the Core i3-2105 and 36% faster than the Core i3-2100, also with the Radeon HD 6570 installed. Please note that even with this video card installed, you won’t be able to play this game due to the low performance achieved.
