At the same speed they likely use similar power, but as dissipating heat is easier in desktop it is more likely to use faster higher power processor.
Laptop processors are designed to use less power and create less heat than desktop processors.
Your question is not very clear but do you mean "what determines the speed of a laptop?" Well the speed of a laptop varies just like a desktop depending mostly on the processor and how much RAM (random access memory) it has.
A desktop processor usually uses more power than an equivalent laptop processor. Usually manufacturers make processors specifically for laptops and these processors are optimized to reduce their power consumption and heat output.
Laptop processors are designed to use less power and create less heat than desktop processors laptop processors are used less power.
the best processor for a desktop is the Intel i7 Extreme which has a speed of 3.2GHz and 8MB of cache
1080 GHZ in a laptop refers to the speed of the processor.
If you are saying to take it out of a laptop and put it in a desktop computer, then no. Laptop processors (as far as I have seen) are soldered into the motherboard, and designed only for motherboards for laptop sizes. Which in that case, it isn't possible to use a laptop processor in a desktop PC.
laptop have fast speed this is wrong answer plz give me the answer og this qyesion plzz
The Dell Inspiron 546 MT Desktop Computer (AMD Sempron LE1300) has a processor speed of 2.3 GHz.
The actual speed of a laptop processor of 1.8GHz i3 3rd generation is 1.8 million commands per second.
high speed of RAM and processor can better support to laptop gaming.
The processor speed of the Toshiba Satellite A355D-S6930 AMD Turion X2 Ultra Dual-Core Mobile Processor Laptop is 2.1 GHz.
