What is the difference between "P" and "T" in processors

[cobra2008]

Some processors are portable, some with T and a number and others with P and a number. They mean exactly what? Is it normal or does that mean something else?

[Marthaz]

Lately that if enough processors are appearing in the series except P7XXX T, P8400 and P8600, there's this table to give you an idea on speed, consumption, etc ... http://www.intel.com/products/proces...ifications.htm

I guess that means that the P are optimized for maximum performance and T for minimum consumption.

P dissipate 25W and T dissipated 35W, that is the only difference. It costs more energy and the battery will last less than with the other

[Alexisus]

P = paid more and consume more
T = yield less and consume less

For the common citizen, it means the biggest advantage since T is a good note temperatures, a bit more performance that is not perceptible by human beings for a single benchmark.

[Fryderyk]

P has a TDP up to 25W.
T has a TDP up to 35W.

T usually tend to somewhat better performance at the expense of consumption and heat, but goes with the model.

P max is the P9600, at 2.66 GHz and 6MB of cache.
T max is the new T9900 with 3.06 GHz and 6MB of cache.

The P8x00, who are more, the cache is trimmed to the same FSB and 3MB of 1066.
