Is there much difference between P4 2.4/400 fsb and 2.4/533 fsb?

I searched the archives but didn't come up with anything. Assuming you have a basic P4 setup, say 512mb pc2100, WinXP home, 40G HDD, and no oc'ing, will there be much difference in performance in gaming and DC programs between P4's with the same Ghz rating but with different FSB speeds? I'm assuming everyday tasks like web surfing would run about the same with both CPU's.

well teh 533mhz bus would have a slight edge over 400mhz via the faster front side bus

but for everyday tasks probably wouldnt show....

Thanks for the heads-up🙂

for o/c the multipliers are different

400 fsb=multiplier 24x= higher o/c 24x 100=2400 if you raise the fsb up to 133=3192 at 150=3600
533 fsb=multiplier 18x= lower o/c 18x133=2396 at 150 fsb= 2700

If you use DDR memory you will get higher memory overclocks with the ratios allowed by the newer 533Mhz Mobos

easier to OC the 400 FSB one.

Actually, I wasn't going to overclock. I just wondered if the CPU's were kept stock, would I be able to tell the difference between the 2 CPU's in gaming and DC?
