AMD Athlon 5350 / 5150 & Sempron 3850 / 2650

Here's some Xonotic test results, but you can get an idea for now between the graphics performance of these AM1 APUs.

With Xonotic there's certainly a noticeable difference between the Athlon 5150 and 5350 with this more demanding open-source OpenGL game enjoying the higher CPU frequency for handling the DarkPlaces-derived engine.

For tests not able to effectively leverage four CPU cores over two, the Sempron 2650 is competitive with -- or can actually outperform -- the Sempron 3850 due to its slightly higher clock speed (two cores at 1.45GHz vs. four cores at 1.30GHz).

With only a $20~25 difference between the Sempron 2650 and Athlon 5350, if your budget allows, you can get more than twice the performance out of the highest-end socketed Kabini APU.
