Intel to Introduce Native 2MB L2 Cache Conroe
 

The 2MB L2 Cache Conroe included Core 2 Duo E6300 (1.86GHz/1066MHz FSB), E6400 (2.13GHz/1066MHz FSB) and Xeon 3040 (1.86GHz/1066MHz FSB)及3040(2.13GHz/1066MHz FSB), where its stepping would improved from B2 to L2. They have new SSPEC and MM, and CPUID would changed from 6F6 to 6F2. However, the change would not affect those manufacturers as well as end users.

it does affect intels profits, in a good way =)
