ExpReview’s got some images from Chinese site it168′s look at the Core i5 3.06GHz.  They run it through a bunch of benchmarks, comparing it to its Core2 Duo equivalent, the E8400.  Looks like there are some sizable differences in the synthetic benchmarks, but the gaming runs don’t show much improvement.

If that CPU-Z screen is legit, the Clarkdale looks to be one heck of an overclocker.  4GHz at 0.832 volts?  Yowza.
