is there much difference between a T4400 and a T3100 ?
Anything marked Celeron, as the T3100 is considered low end. It runs at 1.9Ghz, is dual core
with 1M cache and 800Mhz front side bus. The T4400 is 2.2Ghz with the same cache and
fsb. They are however, different processors with other different specs. To give you some kind
of performance idea, the T3100 gets a Passmark score of 1314, while the T4400 gets 1549.
(Passmark is a cpu benchmark).
In the real world, things like the hard disk, graphics and memory speed will make more difference
to your actual experience.
