more cache = more cash you'll need
haha

I fell like a scientist right now. Thanks Gary
same here....
same with me
"Fell" lol

Gary deserves his own segment on this channel. I know more about mobile technology thanks to his thorough technical explanations. Well done!
Yet another impressive video. Thanks Gary - you make even the most complex topic understandable.
have been a huge fan of these "Gary Explains" videos for a while now. Big thanks to you, sir, your videos always explain things precisely and concisely, and provide enough information for me to understand. Keep up the great work!
I love the way Gary explains everything, thanks dude.
I don't normally comment on videos, but your videos are awesome Gary. The stuff you address in your videos is really tricky, but your explanations are really clear and easy to understand. Thank you.
hey Gary, can you please make a playlist of all your informative videos? Your work is great. I wanna binge watch them
ikr
Android authority plz do one plus 2 vs one plus x
If any one can tell me which one is better
+Ritish Manocha thats a stupid question of-course one plus 2
it has more cache......
+Ritish Manocha Depends what you need but the Oneplus 2 is better specced.
gary is just awesome! we need a playlist of all his videos
von neuman bottlneck is coming from von neuman architecture that put code and data on the same memory bus (as opposed to harvard architecture where you have a separate memory bus for code and data (and often 1 code + 2 data bus because we often deal with 2d data).
Android Authority is so lucky to have Gary
Guru Gary, thanks once again.... :)
+SkMakes Everything 😂😂😂😂
@androidauthority I like the the fact the you guys are making videos on different parts of the Android system, it's very informational. Keep it going, it helps everyone learn more about Android.
I'm a computer geek who was educated in mechanical engineering, so I really appreciate videos like this. My computer science friends just expect me to know this stuff. Thanks.
Your videos are outstanding in quality and incredibly informative. Excellent work!
Wonderfully explained the fundamentals of cache memory and how it works. Thank you Gary.
Gary you make subscribing to Android Authority worth while. good stuff....
I love these kind of videos.... They really broaden one's mindset on how tech actually works. Frankly I didn't know how cache worked before I saw this, so cheers mate! :)
Gary - back at it again with the explanations
I can't believe I just discovered this. Very nice videos Gary!
You are making great and very informative videos!
Thanks Gary ! that actually helped me in one of my subjects in engineering 👍
Gary Sims is like Engineering Explained for mobile devices/tech stuff. Amazing stuff. keep it up !
This video is a single chapter in my graduation... Thanks Gary
Damn Gary, you're on fire lately
Keep it up Gary, love your work.
Another fantastic information video! Maybe you should put up more graphics and charts when talking about clock speeds etc?
I love his videos!!!! I have learned a lot from this guy. Awesome stuff Gary 👍
hey Gary.. could you make a video series teaching us Android Development with Java programming. All your videos are easy to understand cause you explain it very well
All of your videos are 👌
waiting for another one
well explained...great video
Gary very interesting and Awesome video
Great series of videos. Thumbs up!
You sir is always on point. Thanks for explaining
dude u explain better than my teacher please make more informative videos u'r awesome
What about apple A9 how is it faster in single core performance? Can u explain A9 Vs Snapdragon 820
Very informative video once again. Thanks so much.
keep making such videos @androidauthority
Wow you explained things awesomely
Great stuff Gary, again very informative, just one more thing...
if u could attach some references in the description that would be great..
+Vasu Dev :-) Thanks for the feedback, I try to add as many references as I can to the written article that goes with each video.
Well explained! Thanks Gary! 👍🏼
thanks...your vids are very simple and informative
Really enjoyed this one. Thanks!
Hi! can you please create a "Gary explains" playlist on the channel? these videos are very helpful :)
Explained it very clearly, Thanks Gary! :)
Excellent explanation. Thanks
I wonder if using HBM as an effective "L5 cache" instead of DRAM would make a big difference on CPU performance on android devices?
It'd certainly save some space.
this is legitimately helping me with my GCSE 😂😂
+R21 Glad I can help! :-)
very good videos Gary! keep up the good work! Simple and informational videos that everyone should know! recommand to everyone!
very helpful information thank you.
Love to see your explanation. btw, i dont have enough knowledge about it though, i want to know more about Intel chipset cash memories which is user cant access at all. waiting for your next explains... Thanking you:)
what if i disable cashe?
Good going Sir Gary!
great video Gary.....simple question please answer it even ram is limited to 1 or 2 GB in most phones what happens if ram can't manage huge data on it , will it go to hard disk to fetch it again then it affects performance???
i have this in exam in 2 days lol thanks, this helped
How'd it go 🤣
@@scylla_yt7805 well I i passed the exam and working a job now so I i would say great 😂
Great explanation !
is there a way to see what data (i-cache or d-cache) resides inside cache, as we have for main memory (Task Manager) to see what process resides in that??
My question is how you check your Android phone cache memory whether is L1, L2 or L3 as you say...
great video thanks for the explanation.
does cache days affect the battery mine keeps turning off of not it restarts when the battery is 78 or 80 and it gos straight to 8 sometimes it does not do any of that it just randomly go's to 8 or owed in my battery it is very weird
Thank you so much for this, Gary! :-)
Gary videos are awesome
Thank you. Very interesting... So is my cache cleaner really emptying the above mentioned cache? And am I doing something counterproductive by clearing my cache?
+Anantha Bharathan Kurup I am talking about cache memory inside a SoC, that is a different type of cache.
So cache is good? It will make your phone run faster if not empty cache? I always thought it was good to delete cache and it will make my phone run faster and cleaner. I always hear empty cache from people and software. I'm a bit confused atm. Do I not delete cache or?
Does the Cache memory differs between smartphones with the same chip, or can't manufacturers change it?
I just noticed that the background music is a demo song from music maker jam lol
if I delete my cached data to free up space on my phone, would it delete progress in apps that I play ?
Brilliantly explained
Is this the same for pc's
Yes.
Thanks
Of course Not, it's totally different
no ram in pc ram is much faster.
Krishna Sharma Doesn't matter they still need cache memory, some Xeon processors have like 48MB of L3 etc...
so by buying a two way cashe would that double the memory in the cashe?
great information. thank you.
+Gary Sims What is cached data? Will it cause any problems, if we clear cached data?
+Nipun Tj i think no, bt instead of slowing it get more
faster
Clear cache data ? That the software is really different to hardware...
This is great mate, thanks
How many way cache do modern 6th gen intel CPU's have ? one , two or more?
Also if i increase my RAM memory speed , will it get better as it will be close to the CPU frequency?
Is it good to clear cache data frequently? Does it effect my phone's performance?
That was helpful thanks!
This guy is amazing
Eehm I delete every time the cached data to free up some space, am I doing smthg wrong or bad with this?
Please give me a helpful response!
Another great vid!! 👍👍
Good video, thanks!
What if the ram had one core of CPU and use the same ram as cache for that single CPU single core inside the ram?
Can Ram memory be used for Cache in the CPU?
+Gary Sims How to check my system's cache memory any app ?
2:30 VNB
4:15 Cache Hit vs Cache Miss
5:40 L1 & L2
+gary sims
sir, what is that cache memory that we get in smartphone
i usually clear 1 gb worth of cache memory everyday on my smartphone
is it something different?or that memory is stored in ram instead of cache?
u can find that in settings>storage>cached data
+ritik gupta Different thing, that is software, I am talking about hardware.
+Gary Sims
okk thanks sir
this video is awesome
So does this mean that you should be deleting your cache?
what would happen if I delete all cache memory on my phone? I use a Blu smartphone, although I don't know what the exact name of model phone is.
I meant to say *cache data*. I think memory and data are two different things but I some what think they can have similarities.
Feeling Different now! thanks Gary
If a cache can only get up to about 32 MB, then how come when I go to the storage manager on my phone it says I have 614 MB of cached data??
Is ram overclocking possible? My ram is 1.7 ghz
Thank you bro!! Im applying for a NASA open position now: CACHE GURU.
thanks a lot for the videos
Why is it important to clear the cache?
Super informative
Hi Gary! I have seen cache memory nearly 400 mb in my Pad! (nvidia tegra K1) How is that possible? I have checked the cache memory through clean master app.
so clearing the cache makes the pc/phone slower???
You should make a video on IPC and why just looking at the number of cores and the frequency does not tell you how much the performance is.
Yes. I know the fact but don't know why it is that way. Pleeeeease Gaaarry explaaain:D
+AnimeBeefRandoms Yeah, that sounds like a good idea... IPC, branch prediction, pipeline widths, etc, etc. I will add it to my possibles lists! :-)
so when it says do you want to delete cache ....do you ? doe's it help to do that !....I understood it helps speed up your phone etc ?....so please clarify sounds like it's best to keep it going ?! thanks for the video but need an action which is best re the real world user !
+Sky Powers Different type of cache, this is the cache memory in the CPU, hardware, not software.
But why disabled applications using cache memory even after cleaned 😕
well does that mean when I see a CPU written next to it 4M cache that it has a 4MB of cache?
I think so, it's like the "2G" in some gpu names which stands for 2gb vram
+Mohammad Eb typically that is how it works
1) Does android mobiles slow down if cache data becomes high?? They nearly occupy 1.8 GB. I clear them from time to time in the storage settings. Since this is a huge amount of cache data (compared to the cache memory in CPU) , are cached data and CPU cache related in anyway??
2) At 2:45 you say there are several ways around the problem and one of them is cache memory. What are the other methods/ways ??
