So Intel's next big thing, and possibly the way to get the performance crown back - the Conroe CPU has been given a price tag: The E6700, which is a 2.67GHz chip with 4MB of cache and a 1066 front side bus, will cost $529 while the E6600, a 2.40GHz version, will cost $315. The other two members of the Intel Cointreau family have 2MB of cache apiece, with the E6400 (2.13GHz) costing $240, while the E6300 (1.86GHz) will cost $210.
