560j vs 560

[kd2777]

I have noticed that the Intel 560 (3.6) comes in 560 and 560J, and the 3.8 is only available in the 580J. So what is the J. I never saw anything released about this, but then again I have almost exclusively been looking at AMD lately. However it has turned cold where I live and I am honestly thinking about getting a Prescott to keep my room a little warmer until spring.

Thanks

Prescott maybe?

I might be wrong but I think it hs to do with Intel's integrated virus protection. The "J" means it is included.

All LGA 775 procs are Prescott.

That should answer it.

the "J" suffix represents the new "EO" stepping of the CPU. They have that "XD bit" thing, an inhanced HALT state, and TM2 (and probably some other stuff that I can't remember...).

So in short it is better right? I'm assuming it also has a thermal problem? Sadly I want it to run a little warm. My brother has a 478 3.2 Prescott and it raised the temp in his room by 8 degrees Fahrenheit. I was hoping to achieve the same until spring. I know I should probable get an AMD s939 and a space heater, but those things are dangerous.

Yep, the Js are better. But why not get the Athlon 64 and run Folding@Home or another distributed computing app to heat it up if that's what you're after?
