Custom cores versus ARM cores, what is it all about?

1. After arm9 ?

2. Kool

3. What's going on with his shirt lmao

4. the kryo core is in fact a qualcomm design, but it is based on the arm design as well

5. Yea the Tegra 3-4 chips was not very effective, as you pointed out !

6. I just wanted to thank you for a great informative, and we'll explained clip. I always find this kind tech fascinating, and I love learning new things. Keep up the good vid's !

7. Gary is that Qualcomm use too in to a midrange processor like SD 660 , 665 etc ???

8. Maybe you should dive little bit about snapdragon custom core because snapdragon some other soc he use custom core like SD 820 / SD 821 kryo and SD 835 kryo use semi custom. Is not the same semi and fully custom their CPU Core.

9. Can GPU can custom from arm too…. ???

10. RISC – CISC reasoning again. I really don't like having such thing in an informative video, since many people without enough knowledge will believe this reasoning without doubts, although it is completely incorrect. I admit, the reasoning was valid in the '80s, but now it is not! Currently any CPU (Intel, AMD, MISC, whatever) use a small part of the transistors for translating the instructions to small micro-ops, which can be better pipelined, reordered, overlapping can be found and so. I.e. there is a RISC in every CPU. The only difference could be the number of registers, but since x86-64 and the extra r8-15 registers (+ the fast L1 cache), this is not a real issue, the x86 is a RISC inside.
    The only advantage remains is the extra difficulty coming from the "organically developed" prefix-based x86 instruction set, which is much harder to decode, i.e. that can eat more transistors. Somewhere I saw that decoding the instructions takes ~5% of the CPU size. I'm not sure it is right, but the order of magnitude should be correct, so say 5%. Considering that even an ARM CPU needs instruction decoding, you get 1-2% advantage with RISC. At most.

11. A YouTube video where you can actually learn something!

12. Now watching it back in 2019 it seems that Nvidia has fallen of the mobile processor development race. Can you make a video on what happened to Nvidia s Tegra line or what is comming next if you got any info on that… (I know they have the Tegra X1 in the Nintendo Switch, but that cpu is over two years old now and in the mobile tech market that's like forever)

13. stop the propoganda 95% of desktop applications and software are designed as x86 NOT arm ….as such software is proprietary non open source most are not able to recompile to use arm….thus an emulator would need to be used and that will kill any advantage you had ….100% , nice to see you never say this…. on hand helds per brand you and a vender cna make an OS and apps base don it and thats great for apple but it leaves apple as a walled in non compatible with any thing outside its walls. look at blender…are you gonna recode all that for us all ? and then recompile it? how aobut windows it self? or linux OR bsd …ya know what the mac os is based on….see even the apple os is x64 based. they all are except on one hand held phone. Could care less if it was natively 100% faster which it isnt …add emulation to heavy use gf card and cpu apps and that emulation dies on you fast.

14. Intel x86 is not CISC anymore. It converts the "CISC" instructions to ROPS or internal opcodes with wide word width and simple execution. The real issue is that this left the crappy x86 instruction set for compiler writers to struggle with. Are ARM processors simpler? Sure, but that is more because Intel overcomplicates everything, rather than anything to do with the instruction set.

15. But now Qualcomm is jumping to their snapdragon chips for laptop pcs.

16. It's a but misleading to call Intel chips solely being "complex" instruction set chips and ARM solely being reduced instruction set chips. For a long time, Intel chips have used a core that has RISC-like features and ARM chips have used some instructions here and there that are more CISC-like.

17. "Let me explain" oh wait, wrong channel…

18. Arm is going to win because it is focused on one task

19. Dude i was very confused for a while and then i found out this video and i'm really thankful to you🤗🤗🤗

20. I love this. Really like your videos, the depth of detail. I like that idea and practice of 'Costume' core.

21. Damn

22. Can you go over RISC-V ISA?

23. As usual, Gary delivered.

24. Does RISC use more RAM than CISC?

25. Cool. But let me ask a question. While downloading an app from Play store, let's say Google Drive. The original size of apk is 29 . But while I'm downloading, it got reduced to 12mb . Why is it so? Depends on CPU? I'm running cortex A7 1.3ghz mtk 6582. Does this matters?

26. Hello Gary Sims, Thank you for explaining so clearly about ARM cores; it was very educational & informative video.

27. Very interesting…

    But what is the percentage of mobile apps which are optimized to run a 64-bit chip relative to their ecosystem?

28. Cortex a53 or Kryo 260 ?? Help me guys ,, i'am heavy user ultra setting gaming graphic

29. Watching in 2018 April😁😁😁

30. Great but it would be nice if you could describe a few of of the extra uses of the designed arm core in comparison to the prapritory cor

31. I love this man

32. You are the best… I think you are a professor in university…

33. Every other RISC core on the market was optimized for portable C (THE language of the mid 80s) while ARM cores are 'language agnostic'. I can recommend people learn to code in assembly language. An elegant instruction-set producing beautiful (and VERY efficient) code.

34. Actually Nvidia lose because it uses old manufacturers process on it's ship

35. Nice video garyy

36. It's really like to be in a class hahaha. Very good explanation from Gary

37. wht isn't AMD making code morphing ARM chip since they are the only one with x86 licence aside intel?

38. thanks for that knowledge

39. I just love Gary Sims

40. Gary its definitly the most smart Guy from this channel!

41. Heh. iPhone 4s…

    …

    is still using a 4s

42. ARM64 doesn't necessarily mean better performance. Shown by Samsung as they beat Apple in everytime in performance benchmark. Single core benchmarks is another matter.

43. Thanks a lot. It is very informative video!

44. my new bedtime stories

45. But what did Apple achieve by jumping into 64bit? Years on, the iPhonr 7 only has 3GB RAM in the plus version, and I think the iPad Pro is the same. The only difference I've heard between 32 and 64 bit if no need to address more RAM is that 64bit chips tend to run warmer. I don't know how accurate that is but it seems like it was unnecessary for Apple to do so early and for Qualcomm to rush a design and fail in performance.

46. Super explaination and 13 minutes of time well spent. Thank you so much. :thumbs up:

47. This guy makes my favorite videos on Android authority

48. bro very very nice video.

49. You are so good sir that was very informative
