While both AMD and EA released their own benchmarks using the Mantle API, we have been waiting for an independent test and now we have one. The test configurations used by both EA and AMD were a little odd so the guys over at Computerbase.de conducted their own test and the results do not disappoint.
The test configuration that they used featured an Intel Core i7-4770K overclocked to 4.5 GHz and a Radeon R9 290X running in Uber mode. Battlefield 4 was running at a 1920 x 1080 resolution with 4x MSAA, FXAA and 16x AF. You can see that there is an improvement over DirectX, keep in mind this will only be possible with AMD’s R9 2XX cards and currently only Battlefield 4.
AMD has released the Catalyst 14.1 beta 1.6 driver that enables Mantle.
