prescotts run hot, eat power like mad

i think people use watts because it's turns out to be the same thing.

a 60 watt lightbulb generates an amount of heat based on the efficiency of the transfer of electricity -> light.

A cpu is using it's energy to order electons, but most of the energy just ends up as heat eventually on or near the CPU. So the conversion from the energy it uses to the heat it produces is roughly 1:1.

So people tend to just use watts to describe how much energy a CPU puts out because otherwise it'd be confusing for all the morons out there. (Yes, they should probably use joules).

Yes, but it's still what Intel uses to show how much heat their processors are going to throw out...

and the term reviewers are using as well.

"Gone are the days when PC CPUs could get away with just a little aluminium heat sink stuck on top of them, or no cooler at all. When any Intel or AMD CPU on the shelves today is going full blast, it's pumping out heat - less than 20 watts for current Celerons, less than 30 for current P-IIIs, something around the 40 watt mark for current Durons, and better than 70 watts for top-of-the-line Athlons..."

so just what was it you were trying to say with your equation ?!? ;)

Heat has little to do with the size of the heatsink. When used correctly, the term "heat" has little to do with processor cooling. The applicable quantities are power and temperature.

If you read the quote carefully, they are not talking about heat, but the flow of heat. The rate at which heat flows is correctly measured in Watts, and is a completely different quantity then heat by itself. IOW they are using the terms correctly, you just didn't understand them properly.

It's similar to current and charge, current is the rate at which charge moves and you would never consider talking about one processor "using more electrons" then another.

doesn't a p4 theorhetically put out more heat than an athlon xp yet it still runs cooler? Then whats the problem this may run as cool as a normal p4.

The amount of heat produced is also dependant on how long the lightbulb was on. (As a side note, in a lightbulb, most of the 60W would become heat, not light. The power is still 60W however, somthing like 2 W light, 58W heat)

This makes me wonder whaere are we going?
In a few years the cooling of cpus changed from nothing to enormous fans and heatsinks which still aren't enough.What's going to happen in the next few years?

Water cooling will become a standard, more efficiant fans and heatsinks will be designed, and thermo-electric cooling will become more common. Or CPU's will be designed to run cooler...somehow...looks pretty neato;)

With the coming 0.065 micron process they will try to lower the power leakage and the heat problem.

Since 0.065 micron will incorporate Fully Depleted Silicon On Insulator FDSOI and Tri Gate transistor technology which will dramatically reduce power leakage and reduce heat production.

Nobody offcourse knows if this will be enough, but there are interesting new technologies coming our way.

I can't see H2O cooling becoming anything near standard by the end of the decade. H2O cooling is bulky, expensive, and a bit risky. Most people would shudder at the thought of water running through their new systems.

What will happen. Smaller and more efficient processes will be required. As well as better cooling and venting sytems.

i agree. watercooling will never be standard. computers are all about getting smaller, not bigger and bulkier. i think in the next few years almost all home and small office computers will be laptops. prices keep coming down and the ability to upgrade laptops will improve( graphics chips can now be replaced in some new laptops)if this is going to be the trend, then that would rule out any kind of watercooling.

You're taking too much ingnorace juice bud.... Morons? I can find you majors in schools that do not require calculus or physics. My major comes to mind, which is probably why i'm voicing my opinion.

TO graduate from my school you need around 40 classes after all 4 yrs, and a mode of 17 credits per semester.

Ingnorace?
