Which has higher processing speed ?

I'm comparing two Dell notebook specifications :

 

@1) Inspiron 510m @ 2.0 GHz 400 FSB

 

@2) Inspiron 6000 @ 1.86 GHz 533 FSB

 

Both have the same 512Mb RAM

 

What is FSB ? Would option (1) have an effectively higher processing power ?

 

TIA !

CPU processing power has nothing to do with the FBS (Front bus speed).

2 GHz is faster than 1.86 Ghz.

The frontside bus does have a lot to do with the overall CPU throughput. I would guess a 2.0/400 and a 1.86/533 would be very similar overall.

Thanks guys but is there a simple way to compare quantitatively ?

FBS had alot to do with bandwith, overall system performace like memory speed etc.

It does NOT have anything at all to do with CPU performace as the CPU speed is what it is no matter what the FBS is.

So with that in mind.

It is always better to have a higher FBS with equal CPU speed to get the best overall system performace.

 

I know this math doesn't work precisely, but this is just something to think about:

from a 1.86 to a 2.0 = 7.5% increase in clock speed.
from a 400 to a 533 bus = 33% increase in clock speed.

All that, plus the 533 bus means it's an Intel Sonoma chipset (2nd generation Centrino), which has a bunch of other improvements BEYOND the increase in bus speed over the original Centrino chipset, which is in the 400 Mhz bus model you're looking at.

In other words, don't fall victim to the Intel marketing line that CPU speed is everything. Go with the inspiron 6000.

Thanks guys. 6000 it is !

I would suggest the 6000 also. It is newer and will have more advanced technology. I was wondering, does the 510m have the Pentium M or the Pentium 4?
