Fudzilla is reporting that Intel will release Arrandale-based processors on January 3rd, 2010. Three in fact, branded as "Core i5" and "Core i7," ranging in speed from 2.4GHz to 2.66GHz.
There are two Core i5 models. One features 3MB of cache, a 2.4GHz frequency, two cores and four threads plus Turbo Mode, while the other features two cores, four threads, Turbo Mode, 3MB of L2 cache and a 2.53GHz frequency. Fudzilla prices them at $225US and $257, respectively.
Finally, the 2.66GHz Core i7 model features 4MB of cache and Turbo Mode and can run faster. Fudzilla expects them to sell for $332. You'll remember that desktop Macs received Nehalem architecture processors earlier this year, which these Arrandale processors are based on. If built into Apple's MacBook Pros, they'd represent a significant performance boost over the Core 2 Duo processors currently in use.
