Check CPU energy usage details.
In fact, the description matches the original statement exactly. Transistors function based on voltage and current. What isn't utilized is the energy converted into heat. Greater output with reduced heat loss indicates efficiency. The 77w conversion to BTU per hour is accurate, meaning 77 watts of heat are released each hour. Therefore, not all the input energy becomes heat. My apologies, it isn't that simple.
The main point of conservation of energy is that I can point to a box, and say, "any energy that went into this box, will come out of this box, or the amount of energy stored in the box will change." Now draw a box around your computer. Electrical energy has gone in, and no (appreciable) light, movement, or other forms of energy have come out. Therefore, either heat has come out, or the amount of energy stored in the computer has gone up. This could be because your computer is a laptop and the battery is being charged, or the case is getting warmer. Look at this chart from GN: If you look at the Intel stock entries, you'll notice that power at the 12V rail is conveniently exactly the same as the CPU's rated TDP.
What are you referring to? Your Cinebench result is what I’m hearing. The transistor uses power, and the rest is lost as heat. TDP is just an average figure. My Ryzen 2700X running at 3.7ghz under full load has a TDP of about 105 watts, though the actual usage is slightly higher—around 5%. Think of it like a space heater. The CPU doesn’t generate heat directly; it processes data, and some energy turns into warmth because it isn’t perfectly efficient. So yes, a bit of heat comes from both the energy input and its processing. Your idea would suggest it’s always around 77 watts, but that’s not accurate. The heat release happens gradually, measured in BTU per hour.
It's a broad figure since it represents the maximum output any processor can achieve regardless of actual heat generation or power draw. It doesn't reflect each processor's specific TDP, which is why some view it as oversimplified. When applied to heating and cooling calculations, Btu per hour (Btu/h) is the appropriate measurement, though it's commonly shortened to just "Btu". Btu/h and Watt both measure power, they convey the same concept. The energy a CPU uses turns into heat through transistor switching and electrical resistance, with none of that energy being saved elsewhere. A Cinebench score cannot store any amount of energy.
