Xbench score for the 1.8GHz 128 SSD model: 137.12
For comparison:
MacBook 2008 (2.0GHz Intel Core 2 Duo) 126.23
MacBook Air (1.6GHz Intel Core 2 Duo) 50.76
Mac Mini (1.83GHz Intel Core 2 Duo)
94.58
MacBook (2.0GHz Intel Core 2 Duo) 95.89
MacBook Pro (2.2GHz Intel Core 2 Duo) 106.05
PowerBook G3 Pismo (500MHz G3) 18.47
Beats the 2.0 Macbook, and completely smokes the Gen 1 MBA. The GeForce 9400M and SATA SSD apparently make a huge difference. Yes you could buy 2 base MacBooks for the same price, but nobody can call the MBA underpowered any more!
Quite astounding that the old 1.6 only scores 3 times as much as a Pismo.
Oh and whoever said the Macbook Air would not be faster than a Macbook, read it and weep.
