AMD Fusion: Brazos Gets Previewed: Part 2, Performance

Benchmark Results: Graphics

Overall, the new integrated Radeon HD 6310 matches our performance expectations. For the most part, think of it as a slimmed-down version of AMD's discrete Radeon HD 5450.

We see that the Radeon HD 6310 scales similarly to the discrete Radeon HD 5450, though the lack of dedicated frame buffer memory hurts performance relative to the add-in card as you step up to Ultra quality.

The drop in performance using 8xAA is much more pronounced on the 6310 than the desktop 5450, again as a result of no dedicated frame buffer and slower access to system memory.

CyberLink was gracious enough to give us early access to a version of MediaEspresso optimized for AMD's Fusion initiative. We should point out that optimized doesn't mean that CyberLink is shifting more weight to GPGPU processing. Instead, the company is taking advantage of new software hooks. Because of time restrictions, we were unable to get a software-based (no hardware acceleration) benchmark of the E-350. However, given what we saw with other processors, it doesn't look like we are seeing any sort of gain in shifting encoding to the GPU, even when we force the option in the software. Instead, we do see large gains in when the hardware accelerated decoding is enabled by virtue of AMD's fixed-function UVD 3.

Based on the numbers, it seems that AMD's third-generation UVD is almost as fast as Intel's decode hardware. We are told that further improvements should come by way of new drivers.
