Prescott Questions

oh alright, cool.

But if making more stages slows it down...why is intel making more stages??

im sure that theres some sort of advantage

got no clue as to what it is tho

I still would buy an AMD

The Prescotts allow for higher frequencies, hence better performance in the long run.

So will they have those things at like 4Ghz soon? And with that many stages will it be that much diff then a 3.2Ghz with 21 stages and shorter pipelines?

1. 21 Stage P4C with shorter pipelines at 3.2Ghz
2. 31 Stage P4E with longer pipelines at 4.0Ghz

Would number 2 win?

Easily. The Prescott only just loses to the Northwood anyway.


Read that stuff on Anandtech.

so at the same speeds more stages will be slower...but more stages allow for greater speeds in the longrun which will be faster...i think i got it lol

For one thing, Intel extended the pipeline from 21 stages to 31 stages.

HOLY FUCK&#33;&#33;&#33;

31 stages??? that could mean that an aXP would only need to run at 2400 to achieve 3400+

god damn...

what are you talking bout ati? dont understand that lol

Thanks adam that helped me understand it. But those people said it ran hotter, not cooler as more stages should. also arent the pipelines longer so it takes longer to get data from point a to point b? I guess its kinda like you said that the P4 was slower then the P3. I guess it will get alot faster as they develop it..but why release it if its not ready? And is this actually pentium 5? or just a diff core P4 like the barton of amd? [/b][/quote]
Good question big dawg. The chip "should" run cooler, but it does not.

Keep in mind that the engineers who helped develop the Prescott were under IMMENSE pressure from Intel to release the Prescott, largely due to the incredible success of AMD&#39;s Athlon 64 line of CPU&#39;s. In fact, the Prescott was orginally slated to be released on the second or third quarter of 2003. It was subsequently delayed until the forth quarter of 2003, and then again until February 2004. This implies that Intel was having trouble with Prescott; however, this can be expected because Intel, we must remember and realize, are the first to release a chip that is based on the 90 nanometer process.

You have to understand that developing a microprocessor is not something you and a couple of friends could do in your free time; the folks who are behind these technologies are not your average joes, okay...

There are several reasons why these chips may run hotter and have higher voltage requirements than we would expect at this juncture. However, I do not have a degree in tenser equations of the third degree; we are talking about the speed of light here, big dawg. There are all kinds of physics you need to know to understand what is happening with transistors at the molecular level. If this excites you, and you want to learn more about it, there are volumes of information available on the internet. However, you will not understand it without a few years of advanced physics and engineering.

Yeps, if you are REALLY interested, maybe you could find out about taking some MIT or Berkeley courses, or just some local tech college courses.
