Yesterday at the AMD APU13 developer conference, the company showed off the upcoming Kaveri APU running Battlefield 4 completely on the integrated graphics. I was able to push the AMD guys along and get a little more personal demo to share with our readers. The Kaveri APU had some of its details revealed this week:
- Quad-core Steamroller x86
- 512 Stream Processor GPU
- 856 GFLOPS of theoretical performance
- 3.7 GHz CPU clock speed, 720 MHz GPU clock speed
AMD wanted to be sure we pointed out in this video that the estimate clock speeds for FLOP performance may not be what the demo system was run at (likely a bit lower). Also, the version of Battlefield 4 here is the standard retail version and with further improvements from the driver team as the upcoming Mantle API implementation will likely introduce even more performance for the APU.
The game was running at 1920x1080 with MOSTLY medium quality settings (lighting set to low) but the results still looked damn impressive and the frame rates were silky and smooth. Considering this is running on a desktop with integrated processor graphics, the game play experience is simply unmatched.
Memory in the system was running at 2133 MHz.
The second demo looks at the image decoding acceleration that AMD is going to enable with Kaveri APUs upon release with a driver. Essentially, as the demonstration shows in the video, AMD is overwriting the integrated Windows JPG decompression algorithm with a new one that utilizes HSA to accelerate on both the x86 and SIMD (GPU) portions of the silicon. For the most strenuous demo that used 22 MP images saw a 100% increase in performance compared to the Kaveri CPU cores alone.
