What's better?

[charloscarlies]

I'm having a debate with a friend of mine about this. Between these two setups...which should theoretically be faster?

P4 2.4C @ ~ 3.5 ghz
P4 2.8C @ same

Since the multipliers are locked obviously the fsb on the 2.4 would be much higher...which in theory should increase performance. But there's a kicker. What if you have PC3200 that can't run 1:1 on either setup? Let's say both are required to use dividers to get ~200 mhz mem speed. Now what would be faster?

the 2.4C would still be running @ a higher FSB

2.4C @ 3.5Ghz is = 292mhz x 12 using 5:4 divider = 233.33
2.8C @ 3.5Ghz is = 250mhz x 14 using 5:4 ~~~~ = 200

2.4C is faster

------------------------------------------------------
AMD Athlon XP T-Bred B DLT3C 1700+ @ 2.3GHZ (1.775v) 400FSB = 3200+
Abit NF7-S V.2 (nForce2-U400)
Corsair TwinX XMS 3200LL 512MB @ 2-3-2-6 (2.6v)
Sapphire Radeon 9500 Pro 128MB
Antec TrueBlue 480W
Thermalright SLK-947U with 92mm Vantec Tornado @2800RPM
Antec PlusView 1000AMG
Cambridge SoundWorks MegaWorks THX 550 5.1

I would say the 2.4 would still be faster bc of the higher FSB. However unless you actually had some benches to compare, at this point it's like debating who would win in a fight, Mighty Mouse or Superman.

2.4C is faster

Well since most PC3200 won't run 233 mhz without lax timings....it would require a different divider, no? So a high fsb should still be faster even if the memory is running approximately the same speed huh?

Looks like i just won $20! 😉

just get the 2.4c and stop arguing about it

yeah, the 2.4c would be faster at the same clock, unless the only divider you have on your board is 2:1 or something (lol!)

of course, the 2.8c would probably clock a bit higher overall...but that's a separate argument.

the cpu speed doesnt really matter for this comparison.
the FSB also DOES NOT MATTER.

what does matter ~ is the memory speed and cas settings.
in the end thats what will make or break your overall system speed.

>>> a 2.4c running 5:4 cas3447 is going to be trampled by a 2.8c running 5:4 cas2227.

Thank you Thugs. 🙂
