Which would you guys go for, if they are available for the same price? I'm
thinking I'd go for the T8300 of course, but I'm wondering if anyone thinks
it having 1MB less of L2 cache matters.
Core 2 Duo T7500 (2.20GHz, 4M L2 Cache, 800MHz)
Core 2 Duo T8300 (2.40GHz, 3M L2 Cache, 800Mhz)

Since the machines are laptops, then the power reduction on the T8300 seems
good as well when traveling.
The environment these machines will be in is mostly day to day officework
with Office 2003, IE7, document managment software, etc.
Any wisdom you guys can offer?
Other hardware details:
- using centrino's graphics
- 2gb ram
thanks
 
Actually youre pc is as fast as youre hds read & write data,the CPU
isnt the only factor.
 
Yeah I know what parts influence specific tasks, my job covers all that...
but since the price of these two items is the same via my work's vendor, I
wanted opinions for which I should go for, as I have no direct experience
with these two CPUs...

Benchmark in SuperPI mit 4M :

T8300 = 1min 55sec = 115 sec

T7500 = 2min 6sec = 126 sec

2.4/2.2=1.09 126/115=1.096

While SuperPI is not going to show a cache dependency,
it goes to show at least, that "clock rate is king".
The T8300 looks like the right choice.

If the remaining hardware is the same, processor will make a difference.
Speed vs high cache is the issue. I've gone from 2.8GHz to 2.2GHz dual core.
I can't remember their cache but I do know the bus speed is higher for the
2.2 motherboard and I doubled the RAM from 1Gb to 2Gb using faster RAM and
the computer is heaps faster. I know it's not a good comparison - it could
depend on whether you are dealing a lot with calculations vs a lot of data.
I would tend to go with the 2.2GHz if you run on battery a lot.
