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.
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.
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 :)
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.
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
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. 🙁
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.
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.
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 !
Christopher Barnatt, I thank you for another illustrious episode. I am already subscribed to your channel. I have taken the microprocessor and microcomputer technology for granted.
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.
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!
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!
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.
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.
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.
@Chris, thanks for another superb video! This video will definitely help me decide which CPU to buy for my upgrade. In particular, the part about CPU Suffix Codes were really helpful! And what goes with the 67 dislikes? Bots? I'm also really surprised you don't have a million subbscribers already, because you''e an awesome repository of practical and useful info! May God bless you mate for taking the time and making the effort to share your excellent knowledge!
LOL.... me, I've been burned enough times by poor performance and weird bugs that... I'll use an AMD if it falls on my head, but I'll only pay for an Intel. There, let the CPU Wars begin!
Dont be mad at yourself Mr Barnatt - your videos are informative and a typo is nowt these days. As usual when i watch your videos I always learn something. Splendid stuff
I remember well when i was working in Amd Fab25 in Austin and later in Fab 30 Dresden when the first then K7 came through the production. You could always tell because of the dye size. Everybody was so excited how they would perform, we always battled with Intel about speed. The copper K7 was the first to do the 1Ghz, must be in 1999 if get it right, 3 days before Intel. That were pretty cool times.
This reminds me about my business partner, who's fandom of AMD is almost like religion: Whenever our company needs new computers there are 2 options: 1. Right now AMD has better price/performance figures, so we should choose AMD. 2. Right now Intel has better price/performance figures, but the new generation of AMD processors is going to be released soon, so we should wait for awhile.
Two things: - There’s also the Threadripper Pro lineup - The TR PRO lineup is different from other Pro lineups in AMD’s portfolio in that (AFAIK) it’s the only Pro lineup with official ECC validation (both Registered and Unregistered/Unbuffered); All other Mainstream AMD CPUs do support ECC, but only UDIMMs and with no validation, plus its support is on a motherboard by motherboard basis.

Hi Andrew, the old PC upgrades series continues in April 18th and also April 25th. :)
the high prices might also have something to [do] with inflation, i.e. the creation of trillions of dollars by central banks.

Two things:
- There’s also the Threadripper Pro lineup
- The TR PRO lineup is different from other Pro lineups in AMD’s portfolio in that (AFAIK) it’s the only Pro lineup with official ECC validation (both Registered and Unregistered/Unbuffered); All other Mainstream AMD CPUs do support ECC, but only UDIMMs and with no validation, plus its support is on a motherboard by motherboard basis.
