The Anandtech review wasn't entirely balanced however.

They compared an US$378 Intel APU with a much cheaper AMD APU with a lot less CPU grunt. The AMD notebook they used also has a lower memory frequency (1333mhz vs. 1600mhz) and an odd memory configuration (2GB + 4GB, although modern memory controllers shouldn't have any issues with that).
