Which CPU Will Perform Better?

In Multimedia Applications- Celeron D
In Mutiprogramms- P4 (512 Cache)

In gaming, I'd expect the P4 to pull ahead due to the extra cache. It still wouldn't be remotely close to a modern CPU though.

prescott was actually slower than northwood, they increased the cpu pipeline from 21 to 31. the only way prescott had better performance is with loads more cache.

SSE3 makes a huge difference in a lot of modern programs, if the Celeron is late enough to have SSE3 (edit: sorry, reading error) there's a chance it could perform better. But like cjl said, this is no speed demon, and even a single-core Celeron 430 would spank either one (and that's not saying a whole lot).

For reference:

At the same speed the Northwood is slightly faster than the Prescott. It was also initially better at the higher speeds which is why the top socket 478 CPU, the 3.4GHz Extreme Edition, was based on the Northwood core rather than the newer Prescott core. The extra cache will also allow the slower clocked P4 to make up the speed difference.

Anyway, your question is like asking a bunch of stock car racers if a Prius is Faster than an Insight. The first thought that comes to mind is "WTF!", just so you know .

Probably. The Celeron would feel a bit more responsive in Windows though, unless the Pentium was also a dual core.

The Celeron D isn't a dual core...

if you have access to both cpus, why not run a little benchmark?

I used Super PI and the P4 was definitely faster than the Celeron D, but I thought that it might be different if the Celeron was clocked higher. Right now the Celeron is in a Dell so it can't be overclocked yet.

Okay,

I took the Celery D out and overclocked it to 2.66GHz, its actually really fast. Thanks guys.
