13-Way Low-End GPU Comparison With AMD's AM1 Athlon

When running Counter-Strike: Source, at a resolution of 1600 x 900 is where the R3 Graphics were coming in just shy of 60 FPS. The Radeon "HD 8400" graphics were coming in just behind the discrete Radeon HD 6450 and about the same speed as a GeForce GT 220, which is faster than a GeForce GT 520 and GT 610. For the higher-end GPUs, they appeared to be CPU bottlenecked with CS: Source on this Athlon 5350 setup.

With Half-Life 2: Lost Coast, the performance was rather odd with the Radeon HD 8400 running at about the same speed as all of the NVIDIA GeForce graphics cards and the HD 6450, but it didn't appear to be CPU bottlenecked so greatly with the HD 6570/6770 and R7 260X all running much faster... It's not entirely clear what's happening but there wasn't much deviation in the results as reported by the standard error with each of these GPUs running every test a minimum of three times for accuracy via the Phoronix Test Suite.

The Athlon 5350 graphics were running about the speed of a Radeon HD 6450 and then on the NVIDIA side was behind the GT 220 but ahead of the GT 520 and GT 610.
