Apple has just released, quietly and without much fanfare, new MacBook models featuring the faster frontside bus chipset Santa Rosa. The new models also feature better video with the GMA X3100, and a slight speed bump for two models to 2.2GHz.

In summary:

White 13.3-inch MacBooks w/ GMA X3100:
2.0 GHz, 1GB RAM, Combo Drive and 80GB Drive - US$1099
2.2 GHz, 1GB RAM, Dual Layer SD and 120GB Drive - US$1299

Black 13.3-inch MacBook w/ GMA X3100:
2.2GHz, 1GB RAM, Dual-Layer SD and 160GB Drive - US$1499

MacBook Pros can now also be upgraded to a 2.6GHz processor for an additional US$250, or to a larger 250GB hard drive.
