The CPUs are about 70% faster. The 6490M is slower than the 330M GT but the 6750M is a fair bit faster between 50-100% faster. The 2.2GHz i7 quad with 6750M is a fairly impressive jump for a single generation. Usually you only get 30-50%.
The Ivy Bridge die shrink in Jan 2012 will either make another leap in performance or just give a smaller jump with half the power consumption and 50-100% better battery life, while staying much cooler.
