P4 vs Intel Core Duo

[cwebbs60]

I am building a PC for my friend, and the software he needs to run it for requires a P4 3.4Ghz, however I want to install an Intel Core Duo. Want is an equivilant Intel Core Duo to a P4 3.4Ghz?

Since the Core 2 Duo has newer and improved architechure it'll be better. I think a e5200 might out perform a P4?

Yes it will. And it will blow the socks off of the P4 after you OC it. Give us a budget and post in the Homebuilt Systems section adn we'll put something nice together for you.

Back to your origional question, any modern CPU will meet that performance requriement. I'd start by looking at the e5200, if you have a little more money, maybe the Athlon II 250, especially if you just need an IGP. We'd need to know what appliactions/games you're runing to give you good advice, though.

If it's purely a single threaded application then a Core 2 duo at 2.3GHz would preform about the same. Basically the Core 2 duos only need to run at 2/3 the speed of a P4 to get the same performance. Of course, the newer 45nm CPUs have a better IPC and thus a slightly lower speed would suffice. If the application takes advantage of multi-threading at all then even a Core 2 duo slightly below 2.0 GHz may do.

I say just go with an E5200. On the AMD side just about any dual core CPU still listed on new egg would do.

For a big increase, an E7200 will do nicely.

For equivalent performance to a P4 3.4GHz you need a C2D thats clocked at 1.2GHz

Basically, the slowest C2D is still as fast or faster than the fastest P4.
Did you have a budged you are working with?
If you post what you need and what you have to spend we can help you come up with some options.

Atoms won't beat a 3.4GHz P4 in single-threaded applications, though a dual-core might do if you're running four threads.

But yeah, any Core/Phenom chip should.
