Thank you. So glad to have found your channel. Thank you so much for taking the time to create this content thus making this knowledge available. I am immensely grateful, I can't thank you enough. No sarcasm. In short, I came from a very povershed family, always was fascinated with IT, never had even the stability to engage such as my parents are addicts. From the side lines I have watch personal computers grow from DOS and large floppy. Even in school, I wasn't able to delve and explore as deep as my heart desired. Now as an adult, I have the time and the resources yet with all the advancements, I felt lost and was unclear of the very basics that all these awesome advancements surrounding me are founded. So again, thank you, thank you so very much, seriously, thank you. 🎉(❤+Gratitude³)
Hello, wish you live long to make such awasome tutorials. hahaWill you please tell me by which application you make these videos? If you wish.Best wishes from Pakistan.

Vincent Salamatino thats like saying dropping out of school makes you vulnerable to fascist themed conservative blogs (i.e., “truth” or “news”) which alienates you from society so much that owning an AR military rifle is your only protection from the govt thats always out to get you. Lol I’m joking but life is more nuanced and complex than that...
I'd suggest dropping out and getting certifications on your own. A lot cheaper that way. Companies mainly care about the certifications, and not a degree anyway.
This is Far better than my University Lecturer's explanation...Simple and very easy to understands...Thumbs Up for sure...and Subscribe for more for sure
great f..ing explanations dudes. Been watching your vids for the last 2 hours and I've learned so much about how computers work. Now I know what to look for in my next computer purchase (in about 4-5 months, that is). Cheers and keep up the great work!
Crazy helpful vid! As an IT lifer, 1st PC was a Commodore 64, I haven't focused on a PC's RAM, cache and/or guts for a few years now. Flawless knowledge update and the animation locked it in perfectly! On point, no fluff, liked, subscribed and appreciated! Keep em coming!!!!!!
CPU's run so fast they can use the extra waiting time which would be wasted waiting for ram to run extra computations that allow it to keep going, aka checking 3 lvls of cache instead of doing nothing ~. Feels to me like a temporary solution while either dram catches up or sram takes the role.
this was so helpful, im studying for my IT exam and your videos really help me out when im stuck on a part of the book that i have reread a million times. thanks so much!
Dear author of this video, this video is fabulous! You have a great teaching style and a sense for explaining stuff. If you'll ever lack ideas of what to do next in your videos, you sure can ask me! Keep up the good work, it means a lot.
Wow, this video is amazing! I am studying for CompTIA A+ cert. This video just cleared my mind up from all the confusions I had from reading the COMPTIA study guide. Awesome, job! Thank you!!
Bruh! You need to do more of these. You have the perfect teaching formula and the videos are right on point when it comes to time. If you do MCSA and CCNA material the planet will love you for it lol. Trust me man. I've been to college and to several certification classes including CCNP. It took you 5 minutes to explain what I've been trying to figure out for the past 5 years. **aggressively presses the subscribed button**
My family's first Windows (95) PC was a Pentium 150 with no L2 cache - It had the solder pads on the board for the COASt module (remember those?) but no slot soldered in. Between that and the PIO mode disk access it was sooooo slow. I remember it taking over a minute to launch AOL 3.0
This is a really nice explanation. Amazing job! I was asking my computing teacher (who's an owner of a couple of industries) about some informations, and they all were the same as what you explained! I would've suggested to add the speed of each processor, wich is a really simple concept but quite important, but beside that, this video is on point.
It's lines like 2:04 - 2:32 where you come full circle on a concept that make these these videos the best tools for attaining competency that I've yet to find on the internet. Describing the purpose that mothered the invention makes the knowledge thoroughly click into my head. Great Job!
Thanks for the video , I want to add a couple of infos about L1 , L2 , L3 and Cache Line L1 cache : 32KB - 256KB ~ 1ns to 2ns (2-4 cycles) R/W - SRAM L2 cache : 256KB - 1MB ~ 3ns to 5ns (6-10 cycles) R/W - SRAM L3 cache : 3MB - 6MB ~ 12ns to 20ns (24-40 cycles) R/W - SRAM D-RAM : ~ 60ns (120 cycles) R / writing takes longer than 90ns. L3 cache feeds L2 , L2 feeds L1. L3 cache is only used when a task is rather dense or a task, process needs computationally challenging work. - in general use case CPU makes use of L1 & L2 most of the time - Cache Line : When the processor accesses a part of memory that is not already in the cache it loads a chunk of the memory around the accessed address into the cache, hoping that it will soon be used again. The chunks of memory handled by the cache are called cache lines. The size of these chunks is called the cache line size. Common cache line sizes are 32, 64 and 128 bytes. A cache can only hold a limited number of lines, determined by the cache size. For example, a 64 kilobyte cache with 64-byte lines has 1024 cache lines.
This is such an amazing channel, I hope this comment reaches you, you make these so easy to understand!!! I'm just a gamer trying to fix a PC and this helps out IMMENSELY. Thank you so much for your hard work
Finally! I've been wondering for forever what exactly the significance of cpu cache was. First vid that has given it in an easy to understand explanation. Thank you! (new sub)
Excellent video. Great graphics for ease of explanation. You also speak very clearly and at a perfect pace unlike the other 4 UA-cam videos I just watched. Nice work.
Can anyone explain me why the cache memory of even high end CPU is very small(like only 16MB).Means if they can increase the cache memory then the process speeds would go to a next level. Or if they complety change the memory management to SRAM instead of DRAM so that all the data goes directly to CPU cache and then there will be no use of rams. Sorry if it sounds dumb..I am just curious.
The faster you want your memory to be, the smaller it gets. The CPU cache is extremely small, but because of its physical size it fits on the CPU die and can be written/read extremely quickly compared to RAM, which is further away and physically larger. This architecture is used because you don't really need to immediately access every value, but you also don't want to be going slow for everything you do, so you can optimize the process by loading what you're currently using into the cache and then store it when you're done. Most improvements in this area are actually from more efficient ways of passing these processes between the cache and memory, not simply making the hardware faster.
Thank you. This is a well paced video with a clear explanation of the subject. There is none of the needless padding and asides of so many you tube videos. Great job!
Every time I see a tech channel I never saw before, I always anticipate coming in and making corrections... but man, these videos are incredible! Short, compact, and no excessive noise. Fantastic stuff, my dude(s?).
Great content. Clear and easy to understand. I tried learning this from Professor Messer, a couple of Q&As, and even the A+ Study book. This is by far the best explanation I've heard on the topic. And in less than 5 minutes too!
I am confused. My IT teacher at school made the class do a quiz, and got a different person to read each answer. It got to me and the question was about where the instructions for the CPU are, my answer was cache. My teacher told me I was wrong and it is only in the register. Can someone clarify this for me?
technically yeah.....CPU first looked for its required data from the registers.....but registers can't hold an entire or a single instruction that is too complex because of its size...... So CPU must secondly search for those in cache
You an amazing teacher bro. GOD BLESS YOU for all the work I put into explaining these videos and putting them out there... I'm writing my A+ soon and my N+after that and I would say ur videos make me understand better den the damn text book does.. Too much unnecessary stuff in textbooks.. U get right down to the point and that's awesome....

*Thank you very much for that explanation. I live in Germany and my english is not very well. But i understand here more than at the School in the language who i understand*
I tend to learn things much faster and complete when using visual aid and you nailed it. Man I really appreciate your videos and please make more. I finally understand what L1-L2-L3 cache means & why it’s size & variables are so important when shopping for new cpu or pc. Thanks again
Briliant explanation. You read about all this stuff but it makes much more sense with your pictures and digrams. You cna visually see what is happening and it all starts to make much more sense.
pretty sure L1 cache operates differently from L2 and L3 cache, in particular being the memory used for running operations, whereas L2 and L3 are for mirroring system memory closer to the CPU, with L2 typically being per-core and L3 typically being shared. It's an old video, so it's understandably not very accurate, but this is not a great way to learn about cache. There are better resources for it.
In your diagrams you draw the different levels connected in parallel, but the way I remember learning this was that L1 is connected to the CPU then L2 connects to L1, L3 to L2, etc. The explanation you gave in words still applies but the exact mechanism differs between your diagram and what I just described. In the case where the different levels are connected in series, if L1 doesn't have the data then the data gets moved to L1 from L2 (and beyond) for the CPU to access it. In your diagram the CPU has direct access to the different levels of cache and system memory... So now I am wondering have things changed? Or did I never understand this properly to begin with? Or have the simplifications of your diagram lost some accuracy about the details of the process? I hope someone can answer this for me....
I recently built my own computer and spared no expense by buying a 7800x3D CPU. I heard that it's massive L3 cache is what made it really good. Now that I've seen this video, I know exactly why - an 86 mb l3 cache shared between 8 cores means that games with heavy CPU bottlenecks for rendering, like TESIV - Oblivion render really damn fast.
Well, the description of access to cache is wrong. In a system with multiple level of cache the cpu is issuing the same access to all cache including the main memory at the same clock cycle not testing one cache level after the other. Because every cache level is slower with increasing cache level index these read write instructions are queue in instructions queues. If any level eg. the L1 cache responds with a CACHE HIT it will cancel the matching cache instructions in L2, L3 and main memory without impact on throughput or latency (actually latency improves aka gets smaller) a cache miss just tells the CPU to do a task switch or an auto reorder. Thus the worst case latency will not increase (position in queue aka pending READ or pending WRITES.) but can only improve through CACHE HITS) thereby the memory throughput increases with caches and CACHE HITS. In the worst case with data locality not inherent in the data and every access creates a CACHE MISS, the data bandwidth falls back to the main memory bandwidth, data latency and throughput
Hi thank you so much, quite informative and knowledgeable. 🙏🙏 I have 1 Querry though . What is cache memory, like 1MB 2MB and why it is so low, as compared to RAM, which have memory in GBs
Sorry if this is a stupid comment, but from this explanation it sounds like SRAM is far superior than DRAM. Besides the fact that it is expensive, why is it not the standard for memory storing? You explain that SRAM doesn´t have the capacitors, but you don´t say what it has instead?
if all the data comes to the cpu come from the hard disk or SSD or I/O devices then both RAM and CPU cache should be dynamic right? How can there be DRAM and SRAM, both are constantly fed with new data right? Also, if cache is only a few MB then it is constantly fed with data from a much slower DRAM, which creates a delay. So the slowest link in the chain becomes the speed of the whole process right?
I've probably said it before, but gonna say it again: these videos are incredible
Thanks
@@PowerCertAnimatedVideos what about registers?
It's okay dude you can say it how many times you want lol
@@hetaeramancer 😃
@@PowerCertAnimatedVideos can L1 be equated to register? I thought we had registers, L1 cache and L2 cache

where is cache located? inside cpu or outside?
Ryzen does it much better.....smoother in games
I will never buy Intel over AMD the small margin between those CPUs doesn't add up for the price that you will pay for Intel..
I'm used to thinking about the cache as a toolbelt and the hard drive as the tool shed.
