What is CPU frequency scaling?

1. I'm impressed how good he explain it, thank you so much!!!

2. best video i ever seen about cpus

3. Thank you Mr. Gary for the great videos you always make. They are super informative. Would you please talk a bit more about the difference between dynamic frequency scaling used in ARM processors and SpeedStep used in Intel Atom Z series used in some smartphones such as the zenfones as they are more power hungry. Does it mean Intel failed to deliver good scaling?

4. Hi what's scaling governor unknown ? does it relate to the quality of the mobile phone itself? Thank you!

5. I always have this habit of looking someone's eyes when they explain things, I want to know if they look at something behind the camera 😅

6. aí meu proquito

7. thanks Gary informative and awesome as always

8. 🙂

9. Ondemand, by Qualcomm, is generally a good balance between battery and performance for me.
   Interactive is pretty nice, but very battery draining when you are a user with high SOT, like people that use Facebook or Twitter too much.

   Qualcomm does a very good job both on governors and hotplugs.

   Regarding I/O scheduler, I prefer CFQ, but Zen is pretty good.

10. Could you make something like a playlist of videos explaining stuff like this?

11. More vids like these please 🙂

12. I've watched soo many videos on this topic
    Even MKBHDs and his made sense but like from a peers perspective.

    This is like a Great Professor teaching you.
    Now I fully understand
    THANX👏👏👏

13. please keep making such videos

14. Will you be making a review of the Huawei G8 / GX8?

15. what? is that how big.little cores work? I'm gonna root my phone and get all cores working at same time and overclock 2x the normal!! 🙂

16. I've learned a lot from this guy! Thanks man!

17. My phones uses an interactive scaling governor

18. Love your videos Gary. Dont stop making them.

19. Awesome knowledge… Please don't leave this channel

20. hhh

21. I switched my S4 to interactive from on-demand (stock setting), and I'm not sure whether it's better or not.

    Also what about setting the idle CPU frequency up slightly from stock? Could that help prevent lag a bit because the CPU no longer has to ramp up through those steps in frequency? I understand the battery life would take a hit.

22. yes thanks now I know why

23. beautifully explained

24. thanks, this kind of video is really helpful to make smartphone users become smarter, thumbs up for this guy & android authority

25. Excellent explanation. Thanks for posting this information.

26. Man I love your videos Gary! Might not understand half of the things you explain but the half that is understood makes for a great education 🙂 Carry on your great work. Best in class on youtube!

27. that's some info you got there. thanks for sharing it us.

    keep us posted with further updates mate.

28. Mine doesn't even have interactive governer , its got hotplug 🙁

29. make a video on cortex a72

30. Loved this video. Thanks!!

31. he's like Engineering Explained for mobile devices. brilliant !

32. Anyone else use no frills CPU control?

33. Thanks Gary! <3

34. I am using Darkness governor with minimum frequency set to 100 MHz and Max freq set to 2.5ghz .
    Best experience

35. thx made my day see u in the next video

36. Best videos for geeks ^^ Love your videos dude keep us informed!!

37. Concise and informative. Great job. Thanks.

38. very well made video, I hope you keep making more videos like this because you have a way with explaining.

39. i like zzmove a lot, turn the frequency even lower than stock 😀

40. This is idiotic. News flash: VENDORS DON'T USE THE BEST SOFTWARE AVAILABLE.

41. Don't agree that 'OEMs spend millions on this so they know the best'
    Interactive is an average governor at best, there are so many better solutions out there. Also Qualcomm's Mpdecision hotplugging is such an overkill.

42. I thought the default governor that most current phones use is "Ondemand" not "Interactive".

43. very informative thanks, would like to see more of interactive graphics. thanks gary!
