The Intel Core Duo Processor T2500 runs at a maximum of 2 GHz (HFM)
The clock speed for Lowest Frequency Mode (LFM) for Yonah CPUs is 1,000 MHz, whereas it was 800 MHz for Dothan processors. This implies no technical change, simply reflecting the fixed multiplier that applies to the front side bus. For all Banias, Dothan, and Yonah processors, this takes a value of 6. The Highest Frequency Mode (HFM) varies by Core Duo Processor model, ranging from 1.5 GHz (Core Duo Processor LV L2300) to 2.16 GHz (Core Duo Processor T2600).
The minimum CPU clock rate for Intel Core Duo processors in the Yonah series is 1 GHz (LFM).
The following table briefly summarizes the differences among the various Centrino CPUs.
| Intel Banias | Intel Dothan | Intel Yohna | AMD Turion 64 | |
|---|---|---|---|---|
| Clock | 1.00 - 1.70 GHz | 1.20 - 2.26 GHz | 1.50 - 2.16 GHz | 1.60 - 2.20 GHz |
| L2-Cache | 1 MB | 2 MB | 2 MB | 512 kB / 1 MB |
| Process | 130 nm | 90 nm | 65 nm | 90 nm |
| FSB | 400 | 400/533 | 667 | 400 |
| 64 Bit | no | no | no | yes |
