Help Please! Pentium D 3.4Ghz or C2D E6300/6400?

I hope someone can spare a couple of minutes to give me some advice. I `m about to get a new rig from Ebay. At the moment I `ve gone for the Pentium D Dual Core 6.4Ghz CPU, but the more I read this forum the more it strikes me that the C2D 6300 or 6400 might be better. Which is the fastest chip, and what would be easiest to overclock using stock cooling?
Thanks in advance guys!
 
C2D will conquer, and a '6.4Ghz' is a 3.2 dual core i suppose, remember dual core does not mean 2x speed lol. Btw in your logic a 3.4 is a 6.8 not 6.4 :p

There is no such thing as a Pentium D 6.4GHz. It's a dual core 3.2GHz but that does NOT mean the same as 6.4GHz.

The Core 2 Duo E6300 would indeed wipe the floor with the Pentium D at 3.2GHz. The E6400 obviously has a slight clock speed advantage but they'll both overclock to a fairly similar level as far as I'm aware.

In short, steer clear of Pentium Ds now - there is no reason to be buying them unless a). it's dirt cheap or b). you have an older system with a motherboard that doesn't support Core 2.

Sorry, my mistake. Should have said Pentium D `Dual Core` 6.8Ghz (2 x 3.4).

Still wrong though, its not 6.8Ghz its 3.4Ghz. There may be two processor cores, but both are running at 3.4Ghz.

You might as well say a Core 2 Duo E6300 is 3.74Ghz, The only people who call P4D's 6.8Ghz etc are sellers on a certain popular auction website, who are simply trying to con people who dont know better.

Regardless a 1.86Ghz E6300 will beat a 3.4Ghz P4D in every gaming benchmark, virtually all application, and multimedia benchmarks, and 'some' synthetic benchmars.

The E6300/6400 are both easy to overclock, but I would avoid the stock coolers, an aftermarket cooler is cheap, and will keep the cpu running much cooler, even if you only run at stock. And once you clock it, the aftermarket coolers win hands down.
 
Get a Core 2 Duo based system. Do not be fooled by some of the rather stupid labelling of pentium D systems (the worst offenders appear to be on that auction site).

Core 2 Duo is way better!

Thanks guys! Yes, of course, I should have just described the Pentium D as a 3.4Ghz chip. I `ve now changed my order and am getting a C2D E6400.
I `m also getting 2Gb of DDR2 533Mhz/PC4200 RAM. The motherboard is based on the VIA P4M800 PRO Chipset. I `m told, however, that this board is not very good for overclocking. That`s not a disaster by any means but - does anyone have any experience with this mobo?
Thanks for any advice!

One thing, i know that GHZ mean nothing these days could someone correct me on the statement below please:

The new Core 2 Duos are faster than say the Pentium Ds becuase they run more cycles per clock or is it more clocks per cycle lol?

So Intel have copied AMD in a sense?

Also are the Pentium D like two Pentium 4 stuck together like the new quads, 2 core 2 duos stuck together?

Could someone clear that up for me thanks.

Neither - they're more efficient which means they can carry out more instructions per clock cycle.

You could say they copied AMD but that's not really the right way to look at it. Intel realised their mistakes with the P4's NetBurst architecture so they decided to go back to the drawing board and design a new architecture (sort of - Core is loosely based on Pentium 3) which is designed with efficiency in mind.

The Pentium Ds are pretty much just two Pentium 4 cores glued together, yes. Each core has its own dedicated cache and it isn't unified like it is on Core 2 Duo.
 
No, intel didnt 'copy' AMD.

When P4 was made, the 'mobile' group who develop the laptop processors had a different goal, they wanted power efficient processors. So instead of following the desktop teams drive to Mhz, they kept working on the P3, developing it gradually.

And the did a good job, so good infact that people started to notice that a 1.6Ghz Pentium 'M' processor was doing almost as much work as a 3Ghz P4.

But still work carried on enhancing P4, adding extra cores, increasing the clock speed up to 3.73. But the desktop processor team hit a wall, no matter what they did, the P4 core wanted more power and generated far too much heat.

Mean while Pentium M was evolving yet again, into Yohan, otherwise known as Core Duo. Finally someone at intel realised that Netburst just wasnt delivering, and so they took the mobile 32bit Yohan core, allowed it to evolve into the 64bit desktop chip Conroe.

Its possible to trace out Conroes linage, and yes its a direct decendant of Pentium 3, but a lot of development lies between those chips.

Maybe we'll see netburst again one day, we'll certainly see certain aspects of it again, like Hyperthreading.

The E6400 has a higher clock speed, but I have an E6300 so I can let you know what it's like overclocking it.
I got it to 2.8Ghz with stock cooling on my Gigabyte DS3 board, but it was overheating, however I was able to get it stable @ 2.4Ghz with stock cooling in an Antec P180 case and it didn't rise above 55degrees during a 12 hour Orthos.

Hope this helps,

oc.
