モバイル向けIvyBridgeについて
4コアのmobileCore i7が2012 Q2に先行して発売するようです。
Core i5 Core i3のモバイル向けIvyBridgeは、少し遅れて発売するようです。
The Ivy Bridge launch list includes extreme mobile Core i7 Ivy Bridge and two Core i7 based quad-cores that fit Intel's performance market P2 and performance market P1.
To paint a better picture high end quad core extreme Ivy Bridge replaces Core i7 2920XM, faster quad core non-extreme Ivy Bridge replaces Core i7 2820QM, while the slower version of quad core from P1 market replaces the Core i7 2720QM CPU.
Dual cores, including Core i7 and Core i5 parts based on Ivy Bridge 22nm are scheduled to launch in Q2 2012 while the current guideline indicate that Intel plans to introduce its
quad core mobile Ivy Bridge parts and Chief River platform before the end of Q1 2012. One can expect to see Chief River launch before the end of March, but if things get pushed, it might slip to April or early Q2 2012.
