For spicing things up, an AMD A8-3870K "LLano" Fusion APU was benchmarked in a similar setup with its Radeon HD 6550D graphics. The AMD Fusion APU was tested with both of its Linux graphics drivers: the open-source Radeon Gallium3D (R600g) driver and the proprietary Catalyst Linux driver. All drivers were tested in their stock configurations under Linux except for disabling swap buffers wait.
Following the raw performance results are also some performance-per-Watt numbers for each of the configurations. The system power consumption was being monitored from the Phoronix Test Suite via an USB-based WattsUp AC power meter. All benchmarking was facilitated by the Phoronix Test Suite.
