From THW - Good numbers to know
 

Always good to know the target before we pull the triger.

Too bad no one yet has come up with a single table listing thermal loss from CPU+GPU+NB+SB+Mem+HDD+CDROM+MOSFET+Audio+LAN+PSU = Total thermal unit generated inside the case.

Let's not forget heat loss is from deficiency and it is not something that we encourage.

Improvement in this area is not to come up with more energy spent to cool something that has a bad thermal design. The better solution is to come up with CPU and other components with less heat loss; thereby requiring less energy source all together.

"Again, it's interesting to see what AMD is able to do at 90 nm: high load does not cause the new chips to run hot at all."

run the A64 at 2.8Ghz and you will see the same power loss.

Re: From THW - Good numbers to know
 

doesnt the "overclockulator" have that feature? (or at least they were planning to implement it, dont remember)

that's still theoretical ey:)

That is for input power; i.e. a 100 Watts light bulb will require a min of 100 Watts draw of electricity. Now, whether there is 100 Watts in equivalent of heat generated is another story.

On the other hand, a 75 Watts fluorecent light has much lower than 75 Watts of heat generated.

Input=output has no heat loss

Input>output = heat loss

100 Watts input - 75 Watts output = 25 Watts heat loss

Added:

The power loss listed by CPU from AMD and Intel is the max loss. Hence, some lucky guys may get a processor that has way below average loss of energy. In my case, it was the P4 2A which I could overclock 1.2 Ghz with only 1.6V and hardly any heat loss from the process.

The same applies to PSU where you will notice the efficiency factor representing energy loss. The higher the efficiency factor the lower the heat loss.

It all means the power input is spent totally for the purpose the device is designed for as such there is no waste. This is not possible unless it is nuclear fussion or fission when is output>input.
