Question about TDP on multi-core processors

[kitty500cat]

How does thermal design power apply to multi-core processors?

Intel's QX6800 has a TDP of 130W, according to Intel's website. That processor is quad-core; so does that mean that the combined TDP of all the cores is 130W, or does each core have a TDP of 130W?

AMD's Athlon 64 FX-74 has a TDP of 125W, according to the AMD website. So do both cores combined have a TDP of 125W, or each core?

Also, is the TDP the same as the wattage used by the processor?

Thanks in advance.

TDP tells you how much heat the cooling system has to remove from the CPU, so yes, it means all the cores combined.

Yes, present-day electronics convert virtually all the electrical power to heat, so TDP would be roughly the same as the power consumption of the CPU.

Thanks, Nodsu.

That has to take some real cooling and a decent power supply to run an AMD Quad FX platform then. :unch:
