For the graphics results, the numbers from the Intel Sandy Bridge system are unavailable since the Intel SNB graphics driver stack as found in Ubuntu 11.04 is rather broken for this latest generation of Intel hardware. Sandy Bridge graphics are since fixed up in the most latest upstream Mesa / DDX / Kernel components, but not in Ubuntu 11.04. The Intel graphics results for the Intel Core i3 330M are also not available as there was a mode-setting issue to 1366 x 768 (the resolution of the Compal notebook with the Llano hardware) with the Arrandale graphics. That issue too is corrected upstream but is not available by default in Ubuntu 11.04. In terms of the OpenArena results, while not too demanding of a game by today's standards, the Intel Core i3 370M with the NVIDIA GeForce GT 425M "Fermi" graphics were nearly twice as fast as the AMD A8-3500M with its Radeon HD 6620G core.
The NVIDIA Fermi discrete graphics found with the Intel Core i3 370M, as expected, perform much better.
Surprisingly, Llano has an advantage when it comes to Nexuiz where the Radeon HD 6620G with the proprietary Catalyst driver is able to outperform the GeForce GT 425M also on its binary driver.
