Mobile Laptop CPU's?

[calumn]

Hello.

I am looking into buying a new laptop, but Intel's processor range is confusing me, which of these is better:

Core 2 Duo T5200 1.6GHz
Core 2 Duo T5250 1.50GHz
Core 2 Duo T5300 1.73GHz
Core 2 Duo T7100 1.80GHz

The second one has a bigger number than the first, but it has a lower frequency so which will be faster?

I assume that the T7100 is the fastest there, but will there be much difference between them all and if so how much?

Which one would you recommend?

Also, out of these laptops, which would you buy?

Clock speed isn't the only measurement. Look at the FSB and Cache size of those CPU's you listed. You'll see some differences.

go for the advent 8212 if you can, it will have the best performance out of the four
