Intel plans to launch at least three Arrandale-based Core i5 and Core i7 processors on January 3rd and none of them will be what we call cheap.

Core i5 520M, the cheapest of the lot, has two cores and four threads at a base frequency of 2.4GHz and as expected, it supports Turbo Mode and can run even faster. It features 3MB of cache and will sell for $225.

The next runner up is Core i5 540M with two cores, four threads, Turbo Mode, 3MB of L2 cache, a 2.53GHz frequency and as of January 3rd, it will sell for $257.

The last one is called Core i7 620M and it also has two cores and four thread. However, it features 4MB of cache and is clocked at a base frequency of 2.66GHz. It supports Turbo Mode and can run faster. On January 3rd, it will sell for $332 in quantities of 1,000,

In perspective, all three mobile Arrandale-based chips are power hogs and their TDP ratings (including the graphics core) will end up at not so attractive 35W.
