Hello,
Can anyone explain the energy efficiency of transistors in specific CPU. How much of the electricity consumed at a specific time is released as heat. Almost all energy consumed is converted into heat or not? I can't find the answer.
The specified TDP does not answer. It's only tell what cooler is required to dissipate generated heat. Also, AMD and Intel measured TDP by a different methods and are not fully comparable, also TDP is valid for the entire family, not for a specific CPU. TDP is not the same as power consumption. But I found posts in many forums in the internet that claims that TDP = power consumption. Is this correct?
Perhaps the question should be asked - where does power go in CMOS, how much is converted in to heat, how much is losses. If we use MOSFET transistror as a switch, I can find formulas for power dissipation, but for CPU? The Leakage current /power/ in transistors is converted into heat. But there are switching power, short-circuit power due to non-zero rise/fall times e.t.c. Can anyone help for find the answer?
Is it right the claim that power consumption of one CPU at specific moment = 99.99% heat dissipation or almost all electrical energy is converted to heat.
Thank you.
