Windows 7: Temperature values of Mobile CPUs vs Desktop CPUs.....

Temperature values of Mobile CPUs vs Desktop CPUs.....

Today I had a private discussion with our senior member, Britton30 about a comparision of maximum temperature values of mobile CPUs vs Desktop CPUs.

I mentioned that my CPU i5 2410M (mobile CPU) in my laptop has a power consumption of 35 W and a max Tjunction of 100C.

He said that his CPU AMD PhenomII X4 965 BE has a power consumption of 125W and a maximum temperature of 65C.

He said that mobile processors consuming less power operate at higher temperatures.

This does not make sense to me. As an electrical engineer, I know that heat produced by a CPU is directly proportional to the power dissipated by CPU. Because higher power dissipation causes this power to convert to higher heat energy raising temperature to higher values.

I tried to get a clarification on internet but Intel has used different terminology for different processors, like in some CPUs it used Tjunction and in other CPUs it used Tcase. So I can not get a comparision of mobile processors vs desktop processors with respect to temperature rise.

I am still confused about this issue... , and I hope some of our learned members give us an explanation to clear these clouds of doubts..... and let the sun shine....
