Notes on Intel Core 2 Duo T5450

§ Bus frequency is 166 MHz. Because the processor uses Quad Data Rate bus the effective bus speed is 667 MHz

Core 2 Duo Mobile line of microprocessors was introduced shortly after the Core 2 Duo desktop processors. Based on the Core micro-architecture, these mobile microprocessors have many features that are present in their desktop counterparts - dual CPU cores with shared 2 MB or 4 MB level 2 cache, 32 KB instruction and 32 KB data level 1 caches per core, ability to execute up to 4 instructions per cycle, support for SSE3 and supplemental SSE3 instructions, and so on. The mobile Core 2 Duo CPUs have lower Front-Side Bus frequency, lower core voltage and lower power consumption than desktop processors. The mobile Core 2 Duo CPUs not only include all low-power modes of desktop processors, they also have additional modes and features:

Deeper Sleep mode offers better power savings than Deep Sleep mode by further reducing core voltage. From this mode the CPU can transition to enhanced Deeper Sleep mode. In enhanced mode mode the contents of L2 cache is flushed to main memory, the cache is turned off and the core voltage is reduced further, which results in even lower power consumption.
Dynamic FSB frequency switching: this feature allows the CPU to reduce its FSB in half thus reducing CPU frequency in half. Combining this feature with SpeedStep technology greatly reduces power consumption.
Some mobile core 2 Duo processors include Dynamic Acceleration technology. This technology is used to temporary increase maximum frequency of one processor core while the other core is inactive. Performance increase in this mode is not very big - essentially in this mode the clock multiplier is increased by 1.

Mobile Core 2 Duo processors have different model numbers depending on their power consumption and performance. All mobile processors manufactured in Small Form Factor (956-ball micro FCBGA) package have model numbers staring from 'S'. Remaining letters and digits in the model number designate:

T7xxx, T9xxx - high-performance mobile microprocessors.
T5xxx, T8xxx - low-cost mobile processors
P8xxx, P9xxx - high-performance processors with lower power consumption.
L7xxx - low-power CPUs
U7xxx, U9xxx - ultra low-power CPUs.
