Intel Core Solo The Core Solo is the single-core version of the Core Duo and the successor to the Intel Pentium M. The series is manufactured in a 65 nm process and thus consumes less power than a typical 27 Watt Pentium M. Overall performance is similar to an equivalently clocked Pentium M, if not slightly faster due to slight architectural improvements. Example Models: T1200 at 1.50 GHz, FSB 667 MHz, 2 MB L2 cache T1300 at 1.66 GHz, 2 MB L2 cache T1350 at 1.86 GHz, FSB 533 MHz, 2 MB L2 cache (Similar to Pentium M 750) T1400 at 1.83 GHz, FSB 667 MHz, 2 MB L2 cache Ultra low voltage models (maximum 5.5 Watt): U1300 at 1.06 GHz, FSB 667 MHz, 2 MB L2 cache U1400 at 1.20 GHz, FSB 667 MHz, 2 MB L2 cache U1500 at 1.33 GHz, FSB 667 MHz, 2 MB L2 cache
