Intel readies Core 2 Duo revamp?
... these CPUs (E6650, E6750, E6800 and E6850) will now arrive in Q3. Joining them will be the E6390, a lower cost version of today's E6400 but likewise equipped with just 2MB of L2 cache and clocked at 2.13GHz.
... It (E4300) will apparently be joined in Q2 2007 by the E4200 - which once appeared in Q1 2007 but later disappeared - and the E4400, clocked at 1.6GHz and 2GHz, respectively. Again, they run on an 800MHz FSB and contain 2MB of L2. Viiv-certfied, the E4x00 series will not target Intel's business-oriented VPro platform, however.
