About CPU

P is the peryon core, and t is the meron core.

1, core: Intel processors began to use T as prefix, and the latest Centrino 2 began to use P as prefix. P series is the core of 45nm technology, with 1066MHz front-end bus, 3/6M secondary cache (p9 XXX 6M, P8/7xxxx3m), TDP25W, and the main frequency is related to the number after P, where P is peryon core and T is meron core. P series is the latest CPU series of the fourth generation of Centrino (also known as the post-Centrino fourth generation), while T series is aimed at the old Centrino fourth generation.

2. Process: P adopts 45 nm process, and T is 65 nm.

3. Heat dissipation: P series heat dissipation is better than T series.

4. Power: P series is 25W, which saves electricity compared with T's 35W, and increases battery life in disguise. Compared with T series, P series has stronger performance, more advanced technology and lower power consumption.

5. Multimedia: P series adopts a multimedia processing technology called SSE4, which is faster than T series in processing high-definition movies.

6. Front-end bus: 1066MHZ for P series and 800MHZ for T series. (T series also has a 45nm processor and a 1066MHz front-end bus processor. The specific parameters can only be known by the model. ) This is mainly reflected in the memory frequency. The higher the memory frequency, the higher the demand for the front-end bus. If it is DDR3 memory, it is best to match P-series CPU.

7. The difference between 7.T6600 and 6500: the front-end bus, process and secondary cache are all the same, and 6600 is only higher than the main frequency of 6500 100M Hz.
