Mac Rumors reports that Apple has quietly updated the MacBook to the Santa Rosa architecture with mild speed bumps and the GMA X3100 integrated video. Price is the same.
Despite comparable clock speeds (2.0 -> 2.0GHz, 2.16 -> 2.2GHz) to the old models, the new MacBooks use the Santa Rosa chipset which boasts a faster 800MHz front side bus over the previous MacBook models. The introduction of the GMA X3100 video card also provides significant benefits over the previous models.
