I currently have a pc with Pentium 4 @ 2.8 GHz w/ 256KB L2 Cache.
My question is why Intel Core 2 Duo that runs on 2.6 or 2.4 GHz is better than Pentium 4. Is it because it's a Dual Core ?
I didn't see Intel Core 2 Duo @ more than
2.6 GHz, But, P4 has 3.2 GHz and may be 4 GHz.
The P4's netburst technology was highly inefficient. The only way to get any performance out of it was to run it at high clock speeds. AMD's technology was much more efficient, that's why an A64 running at a lower clock speed could beat higher clocked P4's.
Intel went back to the drawing board & came up with the Core technology which is loosely based on the P3 design. It is much more efficient & get's more work done at lower clock speeds.
Have a look at this CPU chart. You'll see the Core 2 Duo Allendate at just 1.8GHz beats P4's at 2.8GHz & 3.2GHz, & it's just slightly behind the 3.7GHz P4.

Thanks for explaining to me, I'm convinced, but, Is it worthy to replace my old P4 with Intel Core 2 Duo ? and If it's OK, Which clock speed should I get with Core 2 Duo, my computer is used as gaming / work computer.
I also know that a MBoard change is required too.

My system specs are :-
P4 HT @ 2.8 GHz w/ 256 L2 Cache
1 GB of RAM
100 GB Hard drive
nVidia GeForce 7600GS 512 AGP 4x/8x
Intel D845PESV (MBoard)
480W PSUAnd.. I don't know what can I write else..
Thanks again.

Looking at your specs, there's very little you'll be able to reuse. Are you prepared to invest in a complete rebuild? AGP is dead & so is DDR1 RAM. And the majority of new boards only have one IDE channel...that means only two IDE devices can be installed. So if you keep the 100GB HDD, you can only install one optical drive. If you want more, you'd either have to switch over to SATA or buy an IDE controller card. Last thing is the PSU...480W doesn't mean much, but if the main ATX plug only has 20-pin, a new PSU will be required as well - new boards have a 24-pin ATX connector.
Here's a rough price breakdown:
Core 2 Duo E7200 Wolfdale - $120
P35 based motherboard - $80
2GB (2 x 1GB) DDR2-800 - $25
PCI-e x16 512MB video card - $100
ATX12V PSU w/single +12v rail - $60
320GB SATA HDD w/16MB cache - $65That puts the cost at approx $450. Are you willing to spend that much? or possibly even more? The E7200 is the cheapest of the Core 2 Duo's...unless you're willing to settle for a cheaper Pentium dual-core (which is actually a stripped down version of the C2D).

Thanks for Info, I'll keep that till I get a chance to change. Getting Core 2 Duo is Double-Edged matter, getting higher speed but, much less IDE , Only two Drives, it's not fair. Ok, no prob about that, I prefer to stay using my system till it dies.
Thanks for answering me.

The IDE dilemma is not so much an obstacle. On average, SATA storage devices are not pricier than their IDE counterparts. I have a SATA HDD & DVD burner in this machine & it didn't cost me any more than it would have had I gone with IDE.
It's good to see that you are willing to stick with what you have until you really have a need for a new system. You are not loosing out on anything by not upgrading to something significantly faster than your true needs.
Good luck.

Thank you fot this reply, my system is currently running on good condition so, there is no need to upgrade but, upgrading from Pentium 3 to Pentium 4 looks more essential because, P3 don't have performance that runs a pc.
In the other hand I'm about to get a new laptop device so, Can I find one with the new Core 2 Duo Processor, please tell me the best clock speed that I should get it or, any other specifications.
Much thanks.

"upgrading from Pentium 3 to Pentium 4 looks more essential because, P3 don't have performance that runs a pc"
Unfortunately, Intel dropped the P3 in favor of the P4. Architecturely, the P3 is a much better CPU. Eventually they came to their senses & dropped the P4 in favor of the Core 2 Duo, which as actually a redesign of the P3.
"In the other hand I'm about to get a new laptop device"
What's wrong with the Dell Inspiron laptop that you have? What is it that it can't do?

That wasn't the case with the first generation Pentuims 4's, the last generation Pentuims 3's outperformed the first generation Pentuim 4's.

Actually, my current laptop is excellent as you say, the problem is that I'm going to give it to someone so, I'm buying another one that's why I'm asking.
And about P3, it has the design but, as you see it can't be used anymore not like P4 it still use-able I think.
And Thanks for your response.

"And about P3, it has the design but, as you see it can't be used anymore not like P4 it still use-able I think"
It depends on what you use the system for. Some people are still plodding along with P1's & P2's, not to mention AMD K6-2's & early Athlons/Durons, so you definitely can't write off the P3 as being unuseable.

Take a look at my sig. I'm playing Blu-Ray discs and watching HDTV with my P3 (with the help of a Radeon HD card). Surfing Flash-heavy sites with ease. Ripping a boatload of CDs to WMA.
It's a very useable family room PC. Performance? Right up there with the P4-2.53/533 according to 3DMark 03's CPU tests. While that isn't much compared to today's chips, it sure speaks volumes about the P3's efficiency.
This ain't ur momma's P3 system:
PIII-S @ 1.66GHz
2GB PC2700
AGP HD3650
Blu-Ray drive
Homebuilt 1920x1200 projector, Pixelworks HDMI controller
JBL receiver & speakers

You're right, I think I overstaded the matter, I forgot that it dpends on how the users use their PC's.
I think this topic is getting longer, so I'll ask about the laptop's performance in another thread.
Thanks for all who answered me.

The last generation p3's when overclocked to 1.6ghz can perform as well as a Pentuim 4 2.2ghz. Like Jackbomb stated, the p3 may not be much now in terms of high performance computing, but it's still very capable of normal computer use.
Heck, I'm still running a AMD K6-2 550mhz running XP SP3 on my old pc with 1gb of SDRAM, an ATI Radeon 1300 pro PCI, and a 60gb hard drive and it still does everything i need it to do on that old pc just fine.

In this case, the clock speed is not the main measure to compare between processors so, what should a simple pc user do when he wants to buy a new pc with the best processor ?
In another words what's the basic measure that I should depend on when I'm buying new processor ?
Is That clear ??
Thanks for replying me.

It all depends upon what you want to do with your pc. A lot of avg pc users are fine with a budget dual core system Pentuim D E-series or a lower class Athlon 64 X2 series. Moderate pc users will go for a Core 2 Duo series or a higher class Athlon 64 X2 series. Power users will go for a Core 2 Quad or Phenom X4 series.

You didn't answer my question actually, If I'm a normal pc user who doesn't know about technecal points about the processors so, how can I really compare between processors ?
What's the mose simple measure that should I know when I'm getting a new CPU ?
