I was just looking around at some CPUs and I am curious about something. My main question is: Is their any sort of difference in performance between a socket 478 P4 3.2 GHz CPU with 800MHz FSB and 1mb cache and a Socket 775 P4 with the exact same stats?

I know that Socket 775 is the newest connection type and so Im curious if 2 P4s with the exact same stats but different socket numbers have any sort of noticeable performance difference between them.

One can be used in a motherboard that will most definalty inculded new and faster verisons, one is already phased out meaning next upgrade cycle its an extra $200 for a new motherboard

Ok I understand that, but between the 2 chips themselves theirs no actual performance difference?

Of course there will be some difference but probably not noticable enhough to worry about.

Actully, benchmarks show that the Northwood in most cases is faster, thanks to its shorter pipeline, also, it dosn't spread heat like a barbecue bar, so thats saving on a hi-power cooler.

However, the advantages of the Northwood CPU (socket 478), are equalled by the fact later on you will need to upgrade to a quality 755 motherboard(any recommendations here?).

It's been a while but if I remember correctly Prescott (with 1MB cache; scales better in overclocking and has the edge in some newer applications, like Doom 3, but in most current applications Northwood has a slight edge. But anyways since you're looking at too Prescotts I think that if you can afford it go Socket 775 Prescott because you can upgrade easily and if you are going for a mid range video card, the 6600-series is pretty dang good for the price (might even make up for the motherboard's cost)

I guess the ASUS 9x5 motherboards are pretty good.

That's not a Northwood he's talking about, it's a Prescott (Northwoods don't have a 1MB L2 cache).

Ah, my mistake.

If you go with socket 775 then you might be able to pick youself up a PCIe mobo tp use.

There is no difference between the two in performance, but you may be able to get goodies like PCI Express with the LGA socket design.

Since hes getting a high end CPU, and if he gets a PCI-E motherboard, he might wait a bit for the 6800GT to arrive to PCI-E...
