Cedar Mill is the same as the Pentium 4 Prescott core with the core being shrunk from 90nm to 65nm (basically the transistors got shoved closer together....this allows for more production of CPUs from a single wafer and allows for less heat generation and power consumption). Presler is two Cedar Mill cores placed together to make a double core Pentium 4 (not a dual core since Presler is simply two Cedar Mill cores placed side by side....not a very efficient way of doing things).
What is Prescott? Any Pentium 4 with 1MB of cache (like the one I have).
The prior one was called Northwood (512k of L2 cache) and the original was called the Willamette (256k of L2 cache).
Heat generated is directly proportional to power consumption.Originally Posted by surasak
Reduced line width primarily allows for higher frequency while keeping the power consumption unaffected.
So don't expect Cedar Mill to run cooler , it will just run faster.
Uh, Cedar Mill lowers power consumption...so lower heat dissipation as well:

...not to mention the fact that Prescott cores are next to impossible to overclock while there is good overclocking potential in Cedar Mill (with stock cooling fans no less).
The result of Cedar Mill compared to Prescott is lower power consumption, slower fan speeds, and less heat generation...the only difference between the two being the core size.
Compared at the same frequency, yes.
But Intel's major goal is not to reduce power consumption or heat, their goal it is to run the CPU faster.
And when they do that, they will be back at the same power consumption as before
Well I can't answer that with a technical explaination but I can say that it is one of the things that I like about my computer.Originally Posted by surasak
It is almost silent. The fan stays on the lowest speed 99.99% of the time.
^ Yes, as I said that is an effect of running it on the same speed as before.
But the race between AMD and Intel is not about who can reduce heat and power consumption in order to build the most silent PC.
The race is about who makes the fastest CPU's within standard working environment (cooling fins and fans) limitations.
Intels line width reduction allows them to increase speed (main goal) while maintaining the same power consumption and heat as before.
The article Surasak linked to mentions the race as the "performance per watt game", and that is what it's all about.
Just for fun here's large database of CPUs and their thermal properties:
techPowerUp! :: CPU Database
^ That is a huge list but no Celeron Cedar Mills listed
My fans on my pc would probably be quiet if I stuck the casing back on, but then it overheats
I'm glad you mentioned that. When are you going to do an AMD XP2600+ overclocking thread?Originally Posted by surasak
I've got an AMD 2600+
It isn't clocked but it needs 3 fans to keep it cool.
I would imagine that cooling will be your biggest problem
^ Mine seems to be ok. The case hasn't melted yet.
Disk keeper is a nice defrag program that can be set to defrag when you are asleep.
^How does it know you're asleep?
Does it stop when you wake up?
^Are you talking about my wife again?
It can if you want it to.

This is as close as it gets:
Watercool your Athlon PC
(Ie wrote ande pute forthe the aformentionede article ine 2000 IIRCe).
Many years ago it was required to get an extra 300-500MHz from the Athlons of the time.
Run CPU-Z and tell me the exact Athlon you have along with the motherboard.
i am still using my old computer (my newer computer should be attended by a nice man from Acer tommorrow).
now the old one is on the blink.
sometimes it wont start up at all and gives me a beep.
sometimes it starts and wont load windows because it tells me that ntfs.sys is missing.
but so far for the past 4 days i have been able get it to start properly by picking the whole casing up and shaking it violently and then switching it on again. Obviously i found this out by accident after getting a little bit stressed.
OK. Here is my home PC.
Ok, in a nutshell: if everything cooperates you should be able to get that up to 2.2GHz (11 x 200MHz) instead of 1.46GHz (11 x 133MHz). This would effectively give you an XP 3200+.
Have you ever attempted this before? Do you have a good power supply (not a cheap crappy one that weighs next to nothing)? Decent heatsink/fan for the CPU?
