As many of you have already noticed, I have spelt AMD EPYC incorrectly in the main table (eg at 1:28 I have it listed as "EYPC" rather than "EPYC"). And I have it both right and wrong on the same graphic at 8:38. But the thumbnail is right! :) My apologies for this -- I so often accidentally transpose two letters and do not notice. So I am mad at myself today. :(
This was the much-overlooked topic for anyone to understand when purchasing different versions. Thank you for sharing in-depth knowledge on two different brands.
"Cache will require a whole video of its own." Yup, please. Cycles latency vs hit/miss/level are scary and tend to make things a lot slower than those gHz clock speeds.
Very well explained. I am an ex computer engineer. Started servicing computers in 1971. The CPU speed then of the Big Iron was 2MHz. No Cache, 64KB memory, 10MB Hard Disk. They also had Printers and Magnetic Tape Units. How things have changed. However what annoys me to day is the change in terminology used, for operations that virtually the same but now have different names. For example Subroutines are now called Functions. Threads is an interesting name, we used to call it Multi-programming. Threads is however a better name. I try not to stay stuck in the past.
This video on modern CPUs in 2021 is delivered by the inimitable Christopher Barnatt in the clear and well-paced way that he always does. All of the facts given here are known well to me, and knew in advance of watching the video that this would likely be so; nevertheless, I watched it anyway simply for the pleasure of seeing this excellent presentation. BRAVO!
I have this same problem... I already know most of the material, but I watch anyway, because if nothing else Chris will organize those facts in a clear and easy-to-remember fashion. Besides, he's so pleasant to watch! Occurs to me that when he was teaching, truancy from his classes was not an issue. :D
Thanks for this, processors these days seem to come out like machine gun bullets, and getting to grips with all the variations and permutations, can be quite a perplexing task. Thanks for the lucid elaboration.
This video was very helpful in understanding the naming of CPU's. I wasn't able to understand the explanation in the previous videos i watched but this was very helpful. Clear, concise and straight to the point. Thank you.
Sir, please upload content everyday. It pains me to see quality content being so undervalued. Your videos might be shown in schools and all but to see only 740k subs is really sad. Your content definitely deserves more value. 9+ years and still this much is really sad.
I’ve seen your older videos for key information and explanations many times, but since they were all from around the 2010 era, I didn’t expect this channel to still be active. Amazing! I suppose I should sub :)
The naming and classification of these chips does seem to be getting more complicated than it was fifteen or twenty years ago. Thanks for the up to date information Chris. 👍
I remember when Intel were producing 386 and 486 chips, either SX or DX for integer or floating point, and only half a dozen clock speeds. It was all fairly obvious. When the Pentium came out, it was nice and simple for while. It all got confusing when AMD, Cyrix and others started adding extra features and developed hybrid architectures with complicated naming conventions. 🙁
Thank you, I had often wondered about the differences between chip and manufactures. I've learned more about my own computers CPU in the last 12 minutes than I ever understood since I purchased it 3-years ago. Again thank you, and have a Happy Easter this day.... ^~^
Thank you for your sound explanations in understandable language, giving basic overviews over technology components. I appreciate that greatly and will point people to your videos who want to have understandable explanations.
Wow 37 seconds ago! Who needs notifications when you spend all your time on this platform. Nothing better than an explaining computers video on a sunny Sunday afternoon.
This is by far, by faaaaaar, the best introductory explanation regarding the Intel and AMD CPU lines. Thank you sir! You have absolutely earned yourself a subscriber in me.
Very clear and concise explanation-- this video has survived the test of three years in a tumultuous market. You would not be surprised how difficult it can be for buyers to obtain the same broad explanation from either the Intel or AMD website. * A small suggestion-- replace the somewhat awkward, "retro" introduction/signature theme with a smoother, more modern theme. It need not be lengthy, but only a brief (voice-less and beat-less) signature. That would transform viewer expectations from the beginning.
Very informative. My eyes glaze over when LTT or Jayztwocents rattle off cpu names and talk as if I’m supposed to understand the differences. Thankyou for explaining !
Excellent! Perhaps you might add the overarching detail that these all use the same instruction set, pioneered by Intel in the 1980s. That is in contrast to RISC and ARM instruction sets.
Thanks a lot, Chris. This is the video I asked for the other day. It's even more complex than I imagined, but as always you made it simple and easy to understand. There are even some CPU lines I didn't know to exist. Thanks again. You are the best.
It thrills me to see AMD making some really superb chips again. Back in the '90s I owned several AMD-equipped computers -- they were cheaper than Intel's offerings and performed every bit as well. I bought my first AMD chip when the 80486 CPU was the most popular one -- AMD sold a 486 chip that was faster and cheaper than anything you could get from Intel at the time. And I kept on buying AMD chips throughout the '90s, as they were always less expensive than their Intel equivalents, and performed at least equally, and in many cases better than their Intel equivalents. Then they sort of lost their edge, and weren't very competitive for awhile. And now they're back in the game and forcing Intel to innovate again! Competition always makes products better for the end consumer, and it's high time we had some good competition in the CPU arena. Intel has been dominating for far too long now. Very happy to see AMD back in the game!
So, that is why I was so confused! Thank you so much for this video. I do hope that a video on cache management is fairly high up in your future plans.
This is quite a "dry" subject but the invaluable advice is quite close to the end where certain AMD processors require a dedicated graphics card as no video signal is otherwise generated - this is particularly pertinent to those who may choose to build their own desktop.
Thanks for that. I was thinking about building a new PC for myself but think it might be safer to just buy an off the shelf model. At least now I'll know what the specs mean. By the way there's a typo at 9:00 - EYPC instead of EPYC. It caught my eye as I was wondering why it was pronounced "epic". Oh, also on slide at 9:14
there's something to be said for that, at least you know everything will fit. AMD's lineup is... slightly simpler now because most of the ones sold under 'Athalon' or 'Ryzen' work in the same motherboard, but even still.
HI, useful info. Be interested in your thoughts on the future of x86 what with the rise of apple M1, Arm etc I read somewhere that the fastest supercomputer in the world is now an ARM powered system.
Perfect video to refresh the knowledge i already had, thank you. Got to keep myself sharp as the nerd of the friends group because i have 10+ guys always asking me ''is this pc any good? Is this one safe to buy?''. Got to keep my bois safe
Even though I know most of this information, I love watching these. I always find something new or something I didn't know before hand. Excellent video as always, you make it very easy to follow any type of person who wants to learn or who thinks they know it all. Congratulations on the 750K subs, here's to 1Million....Cheers!
1. Core m3 has been re-branded into Core i3 since 10th gen. 2. Celerons and Pentiums do have suffixes like T and U. 3. Atoms are end of life except for embedded models. 4. There is also Threadripper Pro. 5. There is also low end AMD APU's that have no branding at all (not Athlon, not Ryzen). Eg. AMD 3020e.
2:04 Clock speed isn't really a good metric when comparing CPUs, my 12yo Core 2 Quad Q9650 runs at 3GHz, but it's an order of magnitude slower than even an entry level 4-core Ryzen would be at the same clock speed. Comparing clock speed is like comparing how fast your car tires can rotate without taking tire diameter (Instructions per clock) into account. Clock speed is only meaningful within the same architecture.
I remember when processors such as the 6809 family, way before 8086 types which led to the CPU's of today! And available ram was 4K and data storage was on Cassette tape of 5-1/4 floppy drives
Christopher I wish this information was available long ago. But it is harder to find suitable information on Intel and AMD CPU chips without having to reading a lot of information. Keep up the good work.
