(Compare oxygen to power usage)īut if you have water coming in at 85 units per second, you're going to need all the help you can get pushing those buttons! 85 / 5 = 17 !Ĩ5 units per second / 5 units per second per person = 17 persons No need to have 17 people present wasting energy (did I forget to mention we're in space and oxygen supply is limited?) when it's possible to only have 8 people. However the minimum amount of people at work is 8 so there will be 8 people (your lowest clock of 800MHz). If the task the people have to complete is push a button every time some water drips into the pail, and each person can push the button up to 5 times a second, releasing 1 unit of water from the pail every button push.Īnd if water is dripping into the pail 1 units per second, we only need 1 person pushing the button. Let's say each person is equivelant to 100MHz of clock speed. Your CPU is only going to work as hard as it needs to, to complete the specified task.Īs an example you can split in your processor frequency into 17 imaginary people. It signifies the maximum speed of your processor.

So, my question is: what does the base clock speed of an Intel CPU actually indicate anymore? Personally, as a consumer, all I really care about is how low (for power savings) and how high (for performance) a CPU can be clocked at. If I earn 10 rep in the meantime, I'll upload the image :) Here's I tried to post a graph displaying the clock speed of my CPU over the time it took to write this question (using Intel Power Gadget), but I need 10 rep to post an image, so you'll have to take my word for it: the frequency was rarely (if ever) set to 1.7GHz. Turbo Boost (with both cores active): 2.9GHz
Take for example, my dual-core Core i7-4650U:
Therefore, a CPU rarely sits at its advertised core clock speed anymore it's constantly changing in realtime between its minimum clock speed, and its Turbo Boost speed. Intel now sell their CPUs with an advertised Core Clock speed, and a Turbo Boost (up to) speed.Īs well as this, thanks to SpeedStep ( dynamic frequency scaling), a CPU will often underclock to conserve power and reduce heat.
