How much faster is a Core2 Duo than a P4 2.4ghz cpu?

[JEDI]

Just seeing if it's worth the upgrade for a gamer as a xmas present.

edit:
upgrade a whole new rig (ie: video card+mem) vs just upgrading the video card

2x!!

Ouch, if it's a P4 2.4, chances are the video card, memory, and hard drive are all circa 2004. Which means gaming on it would take a lot of upgrades.

Basic gaming minimum, for 1024x768 and most common games with medium detail :

P4 2.4 / Athlon XP 2500 / Sempron 3000 / Celeron 3Ghz

512MB DDR Memory

7200RPM Hard Drive of 80GB or larger

128MB Geforce 6600 / 7300GS/GT or 128MB Ati Radeon 9800 / X700 / X1300

On that P4 2.4, it is most likely that an upgraded video card would go much farther than upgrading the cpu. Upgrading the cpu will require a new video card anyway, as *almost* all C2D boards are PCI-Express.

Are talking CPU only or a whole new rig? If CPU only, the first thing to do is to see if the mobo will support C2D.

definitely better than what im running on (p4 2.4C @ 2.9Ghz).

Most definately...if for no other reason than you'll be able to get a MUCH better video card with a PCIe board.

Depending on what memory you have you could do this New system for really few $$. If the 2.4B system was installed with RDRAM Aka Rambus 1066, their is still a high resale value for your used Ram.

That should help in your purchase of new components

anyway, back to my orginal question:

It depends on the clock speed, obviously. The 1.86GHz Core 2 Duo is probably about as fast as having two 3.4GHz P4s (side by side, since this CPU is dual-core). A 2.96GHz Core 2 Extreme would probably be the equivalent of two 5.6-6GHz P4s. No links 'cause this is all guesstimation, but you can be sure that you'll certainly feel the performance benefit.

hi,

I have 2 x p4s [2.66, 2.8ghz] w/ 2 gb ddr pc3200 each and one is 9600 ati pro 128 mb, other is 9800 pro 128 mb ati

there is no comparison of their performance to a core 2. I bought a whole new rig, most mobo now for core 2 duo run ddr2 ram and p4 mobos wont support this.

p4s aren't incredibly slow for common tasks I run them as slave boxes now to do random work I don't want on my main rig.

in short, from someone who came off a non-hyperthreaded p4 seetupf or the past few years and is new to both core 2 duo, ddr2, pci express, and even liquid cooling it's not night and day, its life and death.

It will cost more but if you game, multi task, do a lot of video stuff (encode, etc) then you'll crap your pants at the performance.

people are saying that the quad cores are this and that now that they came out but tomshardware review said only a few things can support them (and their price is absurd) so don't worry about that. core 2 duos will work for years. hell, I've run p4s sine 2002 just fine.

the core 2 could be 10000 times faster, depending on what you consider. you can't compare high ddr2 (1000+mhz) to ddr, dual core to single, (most likely) 7200 rpmp ide 2-8mb cache drives to 7200-10k rpm sata drives w/ 16 mbs cache. as an entire pc, the core 2 duo IMO is well over 3.5-4 x faster purely based on CPU. I'd easily bet a 1.83 ghz core 2 (entry) smokes a 3.6~ ghz p4 by 1.5x+

hope this maybe helps

Which P4 ? 2.4B, 2.4C, Prescott something elsoe

They didn't make 2.4 Ghz Prescotts. Prescott started at 2.8 Ghz I think.

Yes they did, some are still floating around at various online vendors.

Intel's website lists 3 P4s at 2.4Ghz, with 1MB cache and 90nm.

2.4 - original Northwood 400MHz FSB
2.4A - Prescott 533MHz FSB withOUT Hyperthreading
2.4B - Northwood 533MHz FSB
2.4C - Northwood 800MHz FSB with Hyperthreading

I've owned all the above.

 

[sbuckler]

I recon my E6600 is approx twice the speed per core clock for clock then my northwood P4. I.e. at 3.2 it's about the same as having 2*P4 at 6.4Ghz.

 

[The-Noid]

1.62 jillahertz faster. an E6600 @ 2.4 ghz gets approximately 2.7 drystone marks higher (each core), and 3.2 whetstone marks.

Yes they made a canabalized Prescott 2.4, I forget now but it may have had a slower memory buss 533mhz

New Video Card > New CPU for a gamer.

 

[ShadowOfMyself]

Seeing how core 2 duo spanks athlon x2's and they were already much faster than p4s... holy crap.. I have a 2.4 ghz p4 myself and I would assume 3x in single core performance, and 5x+? in multi threaded app

How much faster is a Core2 Duo than a P4 2.4ghz cpu?

Justifiably faster.

Ok, I don?t think there?s a head to head comparison that you can find, so how about this sequence (which focuses on games since that?s the intended audience):

C2D E6300>A64 3800+ (dual core @ 2.0Ghz)

The advantage runs between 5% and 33% depending on which game you look, at with the average @ about 15 %.
Link 1 Link 2 Link 3

Next, let?s remember that dual core doesn?t do much for most games, even the very newest games, so comparing to older single core processors is reasonably fair. And since we are talking about fairly old hardware, the only comparisons are old games.

With this review of Doom3 from 8/4/04 you can see that the A64 3000+ (754) @ 2.0 Ghz is between 26-40% faster than a P4C @ 2.4Ghz, for an average gain of 33%.)

(Now granted, the two A64 chips are not prefect substitutes for one another, but for the sake of getting in the ballpark let?s just pretend that they are.)

So on a very rough level here?s what I come up with working from bottom to top
Your P4 @ 2.4 Ghz =1
1 x 33%= 1.33 (diff b/n a P4 2.4Ghz and a A64 2.0Ghz)
1.33 x 15% = 1.53 (diff b/n a A64 2.0Ghz and C2D E6300)

Soooo . . . I?d say, at very conservative minimum, a C2D 6300 @ stock is 50% faster than the old P4 2.4Ghz. This doesn?t sound very exciting until you put it into to context where it has meaning. If you thought about it in terms of speed limits, a 50% increase of a 65mph speed limit means you can now go 97.5 mph! Here in the context of games, if you match the new CPU with a reasonably capable GPU, it will mean games will run that simply would not run before with details and resolutions that previously would have been impossible.

If I were a gamer with a P4 2.4 Ghz rig, I?d be ecstatic if I got any C2D rig with a PCIe slot to fill for Christmas.

Disclaimer for flamers: I know I made some logical leaps, left out the differences between the 754, 939, & AM2 sockets, dual channel memory, chipsets and that vid cards are a better bang for the $ than CPU?s for gamers. I was just trying to get to some kind of remotely justifiable percentage difference. Don?t flame, show better work.

Huh. That must be why I didn't notice it. Whoops.
