AMD A8-7600 Kaveri APU and R7 250 Dual Graphics Testing - Pacing is Fixed!
Battlefield 3 (DirectX 11)
Battlefield 3™ leaps ahead of its time with the power of Frostbite 2, DICE's new cutting-edge game engine. This state-of-the-art technology is the foundation on which Battlefield 3 is built, delivering enhanced visual quality, a grand sense of scale, massive destruction, dynamic audio and character animation utilizing ANT technology as seen in the latest EA SPORTS™ games.
Frostbite 2 now enables deferred shading, dynamic global illumination and new streaming architecture. Sounds like tech talk? Play the game and experience the difference!
Here is our testing run through the game, for your reference.
Battlefield 3 was running at 1920x1080 at the Medium quality preset in these tests.
Very interesting first set of results! Clearly, the difference in the orange line from the FRAPS results to the Observed results show the dramatic problems AMD has had with CrossFire, Hybrid CrossFire and Dual Graphics up until this point. In fact, perceived performance was actually LOWER than the performance of the APU alone.
A quick look at performance compared between the R7 250 and the A8-7600 (each on its own) confirms what we expected - a solid, but not huge, performance advantage for the R7 250 discrete card. Moving from 25 FPS on average to about 30 FPS, the R7 250 is 17% faster.
The mass of orange color represents the performance of Dual Graphics with Frame Pacing disabled, or any driver prior to this 13.35 beta was released. Clearly, that's...pretty damn bad. The black line is the "fixed" version of Dual Graphics with frame pacing enabled in the driver. Not only are the frame times much more consistent, but performance scales very well with the combination of both pieces of hardware.
Based on the average frame rate, the Dual Graphics combination sees 46 FPS or so while the R7 250 alone hits just over 30 FPS, a gain of 34%
