A leak today reveals that at least three of Intel's mobile Core i5 and i7 parts should be available come the start of next year at moderate prices. The company plans to head up the line with the 2.66GHz Core i7-620M, which will support Hyperthreading to perform the work of four cores. It should carry 4MB of Level 2 cache, support Turbo Boost up to 3.33GHz on one core, and cost $332 in batches of $1,000.

The Core i5 versions are now known by Fudzilla to make relatively few sacrifices and still have the same Hyperthreading and Turbo Boost features, dropping only in cache and clock speed. The 2.53GHz i5-540M will run at 2.53GHz (3.06GHz boosted) and carry 3MB of L2 cache while carrying a lower $257 bulk price. The base i5-520M will run at 2.4GHz (2.93GHz maximum) and cost $225 in similar volumes.

All three models will be based on Intel's 32 nanometer Westmere process are expected to consume about 35W at their thermal peak. They're thought to be shipping January 3rd, just ahead of CES and likely in sync with several new notebook introductions.
