Explaining Intel & AMD CPUs 

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. :(

Two Years of professional IT Training have not been enough to shed a reasonable light on this topic. You have done so in under 13 minutes.Thumbs up!

Finally, an explanation of the secret code chip makers use to name their specific chip models. Thank you!

Wow you're nearly at ¾ million subs, and every one deserved. Onwards to 1m and beyond!

"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.

Hats off to you for the integrated graphics warning. I made that mistake when I built my gen 1 i5 machine.

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.

Finally explained.. and you’re the best explainer, thanks

The most important video; on a nice, sunny Sunday. I now want some tea while watching this :)

I always appreciate how consistent and approachable these videos are.

Every IT teacher could open your channel, set the videos on auto play and students wouldn't miss out on anything. Maybe learn even more! Amazing job!

Love the foundational computer lessons like this regularly thrown into the mix of this channel. And explained clearly per usual.

Me so happy. Another video. Thank you for making these videos every Sunday. It makes my Sunday complete.

This guy really likes computers he should teach us about them

Taking my comptia A+ and net+ and enrolled in IT and computer engineering classes at community college your channel has helped me so much

Your explanation of the product codes was especially interesting! Thank you!

Happy Easter everyone. Chris, thank you for this video. Very timey and gives us a n overview on all types of CPUs. Great stuff. Enjoy your day!

Another excellent video! You always present the information in such an easy to understand format!

This is probably the most compact explanation I found by a quick search. Good job!

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.

Helping the algorithm to pick up your video

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 :)

It is the first time in 20 years I get such a nice CPU overview. Thanks a lot. Great job.

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.

Thanks for the information. Looking forward to your next video!

This has been such a treat to watch thank you kindly!

Awesome.... No one explains things better than Chris and this channel! Nicely done!

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.

Eyeopening as always , thanks Chris , stay safe

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.

Easily the best breakdown of CPU/GPU families that I've found on RU-vid... and all under 13 min!

Another excellent video which I wish I'd had a while ago when trying to work out the differences between the PCs on offer. Thanks yet again.

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. 👍

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.

Thank you ExplainingComputers! Awesome and informative video as always!

Very informative! This channel has become my Sunday tradition. Happy Easter everyone!

That's a highly detailed video about CPUs, sir. Please make a video about GPUs.

I was waiting for this.

I just watched your video on the AArgon M2 Case. You always do such a nice job. Thanks.

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.

Thanks for doing such great Videos!

I remember when processor speed was measured in MHz.

Congratulations on 750K subscribers Chris, well deserved, great content as always.

Finally found video that explains almost every detail about CPU. Extremely useful 👍 Thank you!

Just as I am about to get myself an ARM Raspberry Pi, you make this. Bravo, Mr. Barnatt 💪😅

The Intel Core Blimey is only available in the UK.

Man I love your videos on computers , Very detailed and elaborated. Keep up the good work.

Once again - you've produced a hugely informative, and much needed video. So once again - thank you!

Please make a video telling us about caches. That would make a nice followup for this one.

My man's face is like 3D rendered on a pc , he couldn't look more techie , even if he tried. Thanks for the video.

Dude, this stuff has never made till today. Thanks

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!

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 !

EPYC Chris, not EYPC.

Great video, looking forward to a similar video about GPUs.

End piece on pricing very well thought out & carefully phrased.

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.

Happy Easter, Christopher.

These videos are always very helpful and clearly explained, keep up the good work!

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.

Just started the video and got an advert for ARM... :D

Funny that we still call them "micro" processors. They should be called nano processors 😂

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!

Thanks for the information regarding the suffix of the processor models

You'd missed out the A-series on the AMD side

Could you also make video about how CPUs work on the inside, and about CPU socket types and their advantages and disadvantages?

Thank you for the eddumacation(education) on the cpu's, as always I enjoy watchin your channel, keep up the great work.

YAAAY, I’ve waited ages for this video!!!!

7:50 He's rhyming so well.

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

Brilliant overview and explanation, thanks as always!

Thank you for another excellent and thorough explanation of what is available. It is easy to lose track with so many CPU models around.

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.

Love you and your voice

Another week another awesome video! 🤘

ive gotten behind on my knowledge of this kind of stuff. ty so much!

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.

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!

Thank you for this Easter present EC, by far my favorite computer channel

Many thanks for this comprehensive and enlightening video on the often confusing world of microprocessors!

I wonder how Intel's hyper threading compares to actual double core count

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.

We need more of this! Pls make more videos, great stuff!

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.

What happened to your series on upgrading an old computer?

I picked a bad year to build a gaming pc. ALL decent graphics cards are "Out of Stock" Thanks bitcoin!!

All these cpu families and models can be hard to remember. This video really makes it clear for me. Thanks!

Excellent explaining there Chris, I actually learned something I didn't know, thanks.

1:22 8:38 misspelled EPYC as EYPC

Looks Like I am not late this time!!!

This video so good I would actually pay to share this to people

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.

1:24 EYPC, epic ?

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.

Fabulous!, exactly the kind of basic info I was looking for, as I'm someone with no specific computer/electronics training, just an interested user.

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.... ^~^

Very informative. I only understand low-level language.

You should send this video to Intel as they clearly have no idea about their own naming conventions.

And another VERY informative video. You make it crystal clear. Thank you.

A trip down memory lane, thanks Chris
