I havent built a new PC in a few years so I am a bit out of date on the latest and greatest CPU's and such.

My current PC which is a couple years old or more is using a Intel Pentium D 3.2 GHz processor. When I look at the newer processor's most of them are lower then a 3.2 ghz. Why is this? It is somewhat confusing to me as it would appear as if they got slower but I know this can't be the case.

So what is the best and fastest Intel CPU's today? I need something that is FAST for hardcore multitasking and running a lot of CPU intensive programs, (photo, video editing, games, multiple programming IDE's, other large programs being ran at once, Dev webserver, more)

I think you should narrow your list of targeted apps to run at one time, otherwise it might sound as if you are looking for a server and not a personal computer... – Shaihi Feb 16 '10 at 6:39

Could you please rewrite your question? I feel like you have two questions in one: why don't frequencies keep going up and what's the best CPU at the moment? The first would be interesting for some people to know, but the second will be outdated as soon as it's posted and fairly limited in usefulness. – Ivo Flipse♦ Feb 16 '10 at 7:16

This question is unlikely to ever help any future visitors; it is only relevant to a small geographic area, a specific moment in time, or an extraordinarily narrow situation that is not generally applicable to the worldwide audience of the internet. See the FAQ for guidance on how to improve it.

Trying to talk about processor Mhz speeds and effective performance across different applications can become a long-ish article.

How about taking a peek at this Intel Desktop Performance summary page as an example.
It refers to the Intel Core i7-950 & i7-920 processors; i7 specs.

Some references for further reading,

i7 specs is definitely the fastest Intel processors . Especially Intel CPU is really good for photo editing, encoding ... Nice link for you to check CPU comparison in many aspects :) Tom's hardware Comparision

If you're willing to wait a few months until the middle of 2010 then hold on for the Core i9, they're 6 cores built with a 32nm wafer.

This atrticle shows a benchmark against an i7

But that will never end. A few months after that you'll have the next generation. – Nathan Fellman Feb 16 '10 at 12:28
