whats better a 3.4 ghz cpu or a 3.8?

[Phaihn]

a 3.8 ghz pentium 4 cpu with 1m / 800 mhz fsb or a 3.4 with 2m / 800 mhz fsb

Re: whats better a 3.4 ghz cpu or a 3.8?

the 3.4 will give better performance - the cache size makes a lot of difference.

Re: whats better a 3.4 ghz cpu or a 3.8?

for sure the 3.4 with 2mb cache. but why p4s? and is it pentium d-core, northwood, or prescott? actually i'm sure its probably prescott, so why prescott? you can probably get an athlon64 or something similar for really cheap and it will be faster.

Re: whats better a 3.4 ghz cpu or a 3.8?

3.4 with 2mb cache. And this can't be a 478.. The only 478s with 2mb cache that I'm aware of were the Extreme Editions. What he probably has is an LGA775 Pentium D.

Re: whats better a 3.4 ghz cpu or a 3.8?

I'll always go with more cache.
The $$ kind too.

i dont like amd besides its for a system i got for 50 bucks its a socket 775 mainboard with case no hard drive a dvd rom burner windows xp coa on the case has a celron d in it i want a better cpu thats why besides i like Pentium 4 its gonna be a great upgrade to my main system.

your right but its a 775 celeron d in the case but i want to put in a P4

yeah thats what i was thinking.

Not to be an ass but what is there to like about the P4?
I give you a challenge; find a reputable review where a Core 2 Duo with any stock clockspeed is beaten by a stock Pentium 4

Sure it can be done but A Pentium 3 1Ghz is faster than a Pentium 4 in many tests
Pentium 3 Tualatin 1.4Ghz can beat the P4 in tests where the P4 approaches 2Ghz

The AMD Athlon64 processors eats the P4's for lunch
And the Core 2 Duo processors eat the Athlon64's for lunch
And you say you have a S775 mobo?

Re: whats better a 3.4 ghz cpu or a 3.8?

They are both socket 775 I am sure. You cant get anything faster than a 3.4 in socket 478 and the 2 meg lvl 3 cache of that chip is a Gallation core which is kinda rare now.

As to which is faster it depends on what you are using it for.

If its cpu clock speed intensive software (like say EverQuest II) the 3.8 will smoke the 3.4.

Are they single core? are they Hyper Threading? are they 32 or 64 bit? are they dual core? are you going to overclock?

Model or S-spec #'s of the 2 chips you are comparing along with the intended use would help to provide you with the answer you seek. :P

i dont like AMD simple as that and i am looking at a pentium d too it looks nice but i am not sure waht will be better the pentium do 3.4 or the pentium 4 3.4. pentium d has a 4 mb cache

Like I said it depends on what its used for. Standard benchmarking yes any newer cpu multi core will beat a faster clocked older chip. But if its used in a app that is based on cpu clock speed (and there are alot out there) the older fast clocked chip will be faster.

I have a 3.6 64 bit hyperthreading socket 775 P4 with 1 meg cache in one machine and a 3.4 64 dual core Pentium D 2x2 meg cache in another, other than that they are exactlly the same in all hardware and the 3.6 beats the 3.4 in some apps and the 3.4 beats the 3.6 in others.

yes its a socket 775 well the pentium 4 should be a HT core.. ill probley use it for WOW and a few other multimedia things like music and videos

Re: whats better a 3.4 ghz cpu or a 3.8?

i dont over clock the p4 is a single core the pentium d is duel

Re: whats better a 3.4 ghz cpu or a 3.8?

and i dont have a 64 bit os just windows XP home so the duel core wont do me any good.

Re: whats better a 3.4 ghz cpu or a 3.8?

see if your new found board can take a c2d or even the cheap pentium dual core.anything should stomp a presscott.

this is waht i got. http://www.intel.com/support/motherb.../cs-026950.htm

D915PCY

the CPU it came with Intel® Celeron® D 331 SL7TV only 2.66 GHz 533 MHz 256 KB

and from the looks of it it wont take a duel core or a pentium d so pentium 4 it is.

Re: whats better a 3.4 ghz cpu or a 3.8?

LGA775 Pentium D is not Pentium 4 at all IIRC but Dothan. Oddly enough, the 865 chipset can take both Pentium 4 (Netburst) chips and Dothan-based chips (Core Duo, etc...). I've seen a motherboard with an 865 that had a socket 775.

i knew that. :>

[pegdizzler]

Re: whats better a 3.4 ghz cpu or a 3.8?

Unfortunately, Pentium D isn't Dothan at all. =P

Dothan came after Banias (both Pentium M, mainly mobile but some desktop use) which actually was derived from--you guessed it--the P3. Namely, the cool running Tualatins.

The spec sheet for Pentium D is here:


It's Netburst! As Per Hansson and others have stated, P4/Netburst stuff isn't really economical anymore. Sure, one core may be fast, but almost any competing CPU architecture a generation newer OR older than it will be far more efficient. If you don't pay the electric bill, it might not matter to you as much...
