AMD is keen to emphasize that its APUs feature powerful integrated graphics capable of doing serious GPU computing work. We didn't have a chance to test any apps that harness Kaveri's HSA capability, but we did run LuxMark and Musemage, which use the GPU to speed up 3D ray tracing and image editing, respectively.
For LuxMark, we ran the LuxBall HDR test. For Musemage, we simply fired up the built-in benchmark.
The Core i5-4570T comes out ahead in LuxMark's CPU-only benchmark, but Kaveri has the upper hand in all of the other tests. Again, keep in mind that Intel's 35W mobile chips have higher graphics clock speeds than the i5-4570T. Based on our desktop results, however, it seems doubtful that even a higher-clocked Haswell IGP would match Kaveri's built-in Radeon in Musemage and LuxMark.
Graphics and gaming
Well, those 3DMark scores are awfully close. Might we see a similar equivalency in actual games?
To answer that question, we ran three titles from our Steam library: BioShock Infinite, Dirt Showdown, and Tomb Raider. We ran these at 1920x1080 with antialiasing disabled. "Medium" detail presets were used for BioShock and Dirt, and the "Low" preset was selected for Tomb Raider. Since testing time was limited, we used each game's built-in benchmark.
The answer seems to be "nope." Kaveri is the clear winner in these titles. Heck, even the two-year-old Trinity chip comes out ahead of the Core i5.
This is probably a good time to point out that the FX-7600P seems to have enough muscle to maintain playable frame rates in DiRT Showdown and Tomb Raider at 1080p—which, you know, ain't bad for a mobile processor with integrated graphics. Performance in BioShock Infinite wasn't quite as impressive, but that's my fault. I should have tested at the "Low" detail preset rather than "Medium." Unfortunately, by the time I'd realized my mistake, I was already on the plane home. Such are the dangers of out-of-town benchmarking sessions...
