Hey this was incredibly produced and clear enough for many people to understand, you guys should publicize it more because i stumbled upon it almost casually.

When a actual Microprocessor company makes a video UNDERSTANDING how they work? Heh, and for the fact this actually isn't made bad. Don't get me wrong other content in KZread that explain this sometimes can be easier and maybe harder. But I actually am amazed Intel really is doing this

I want intel to make more technical video like this. The more the better, I have a genuine interest for the inner working of the product instead of just buying it and wish for larger caches , better features.....As a customer , I really love your dedicated effort of creating a highly understable video with good analogy
Honestly Boyd Phelps did an incredible job with these two videos. Granted I've been around since the 486 days and have always had an understanding of the various CPU architectures, but this was incredible with it's depth.
I love this series! It's incredible how these devices even work without a hitch given how mindbogglingly complex they are.

What's really amazing is they don't run without a hitch, there is an acceptable error rate that they recover from. That is part of why systems are more stable today than previously, more threads, more cores, if a thread crashes it doesn't take down the entire system. It's not just at the CPU level but errors still exist they just don't take down entire systems as often.

Incredibly well done, breaking down such a complex topic into chunks that are digestible isn't easy and you guys did that super well!
I don't normally thumbs up or comment on a video, but, when I do, it's because a channel has done something really amazing and I want them to continue!
This was actually incredibly well put together! I always found that nothing really would ever bother to explain how exactly the subcomponents of a CPU talked to eachother, but this really helps show how a CPU is a lot of smaller, specific-purpose modular pieces talking to eachother
Thanks Boyd for these very clear video's i knew the basics but Part2 was very interesting and helped me to paint a clearer picture of what was going on. I would love to see more of these video's and even go more in depth!
Having had the opportunity to be at Intel for years (no longer there), so proud to see these series coming up. Very well done, something rather complex explained in a simple form. Hope that entice and nurture the imagination and curiosity of everyone, especially younger ones!
This is absolutely brilliantly explained and presented, thank you.
Love it. Explanation on branching and speculative execution is great. We must emphases that branching is the key of turing completeness which permit the birth of computer from previous simple calculator.
24:30 Yes, it was very beautiful 😌
Love this intel!!! Do more of it and yes let the world know about this. Ads maybe.

This magic! many civilizations shook
Absolutely amazing, thank you!
Very well explained. The microcode decoding part was especially informative.
This is beautiful.
The content of this video was so clear that I saw myself working at an intel lab for a brief second in a near future. Thanks Boyd !!! Great Video
It was truly remarkable. The best and most stunning lecture about CPU that I've ever seen.
Absolutely brilliant. From start to finish.
Lots of information with high quality content. Great effort Intel !!! And the host is doing an amazing job. His way of teaching is marvelous. For the last few weeks, I was searching for the topic "Computer architecture". Since, I am a hobby programmer, I would like to know more about how CPU execute my code. Thanks a lot for this series. :)
Fantastic! Thank you!
This is literally amazing. Great explanation and great work on building these technologies. Speculative execution was really cool for me to learn about
This is entertaining :) I already have a CS Degree and work as a Network Forensics Analyst but I still find this entertaining better than watching some non sense videos. I like learning about the physics of the electrons or photons inside the CPU highway and logic gates and conducting test's of new architecture designs in a digital 3D simulator environment.
Awesome animations and analogies, altogether very easy to understand! I admit I'm heavily biased, but I think even a lay person with some passing interest would be able to understand a few of the important big-picture points.
Oh thank u very much! reading "Inside the machine" book for now and it was too hard to understand all of this. This is great videocourse!
These videos are so impressive, I would pay for a full course
Extremely motivative and well comprehensive.
Well done, Intel. Loved it. Wish there was more of this.
Thanks for this content, I liked it. I wish and hope more technical content like this one in the future.
great video with excellent graphical representation to simplify the complex concepts.
This is so good, it is easy for a newbie to understand. And it’s not boring for someone who’s already knows how a CPU works.
Seen both parts. Great....
Thank you Intel for putting this up. I like it a lot!
Thanks so much. This is fantastic. I'm using this to teach my daughter.
superb. mind-blowing. beyond one's imgination!
Loved it. Thanks!
This was amazing, thank you!
what a beautiful and educative illustration!
I really liked the TV sticks with the embedded technology they came out with. Above all I've found that the key to unlocking the potential of any product is to have in specification RAM from a quality manufacturer!
It is a freaking miracle that we can make these things work reliably!
This is just awesome!
Great summary of uArch. Awesome!
The editor needs a raise
thanks for complete and clear explanation
Awesome videos I can show people to help them understand what I am talking about, only thing I think was missed(unless i missed it) was how hyperthreading works in the pipeline.. that'd been cool to show.
This was actually extremely informative. I already knew a little bit about micro-architecture before hand. And now, seeing how some of this works, both the re-order buffer and branch prediction seem like they could be exploited to run unsigned code.
Incredible! the explanation and animation both!
Thanks for the video. I learned interesting things !
Keep it going!
Great videos, thanks!
I have not got words for congratulate this amazing videos !!!
This is an incredible video!
I am in chip design from 1984 and tried many times to explain to people what am I doing. If I would have had these videos my explanation could have been easier. The animation and graphics are unbelievable quality. The Part 1 is a good umbrella explanation of the chip design in general and CPUs in particular. I will call this the 10.000 feet view. The Part 2 is the 1 foot view directly into the processor architecture so some industry lingo and knowledge is required. I would have liked to have a 3.000 feet and a 100 feet view for popularizing chip design and CPU for people who do not have an electronics background. Intel has all the capabilities to do it so please consider it. In the times of Artificial Intelligence and Biotech advancements making more people understand where all started and how it humans can benefit from their merger should be a good topic to cover. Looking forward for new videos from you.
Thank you for this beautiful explanation of modern cpu. I hop you don't stop producing this series. I think GPU will be interesting topic to discuss as we all know intel have great iGPU today and hopefully will release discreate gpu soon
Thank you.
JUST AMAZING... thanks
That was soo soo fantastic, I can't believe it wow.
Will you make more of these? They were incredibly informative: before, caches and pipelining were this black magic that was hard to reason about, especially as my previous reference point was essentially AVR MCU architecture (let's leave aside PIC because that's an entirely different beast altogether).
Please keep teaching us similar content. Some people like us are thirsty to learn
Great video, congrats for making it!
very very great video!! thank you very much!
Amazing...
Please do more of these! I'm really enjoying the series.
Stellar presentation!
Highly informative
great and simple explaination dude
This is really good, nice video
Excellent Presentation.
Man if you guys could go even deeper, it whatever just amazing work
Haven't been this captivated since reading Peter Norton's pink shirt book; "Programmer's Guide to the IBM PC". Deep and geeky is what the future is made of.
Great job and great video!
Fantastic!
This is a great series! Hope there are more of them!
This mini-series was excellent! yummy good!
This guy is awesome !!
Totally found this by accident, but so informative.
Mindblowing
Outstanding
very helpful for CS students
Well processed.
Very well done, but still waiting for the cache episode.
Exceptional.
Boyd is brilliant
Nice!
we need more people educated on this!
This is an incredible video!! Leave it to Intel to produce it. Thank you!
Incredible
Good stuff. This was highly interesting watch. Enjoying my 11900K. Looking forward to Alder Lake and Intel’s GPU launch.
Loved it.
This was really cool. Any can get a part 3 that explains how this is all translated onto a physical processor? How do we take these concepts and functions and make them work in the physical world?

Think of it in this way, trillions of electric signals go through a CPU, these electric signals are sometimes of low current, sometimes of high current. Low current is interpreted as 0, while High is interpreted as 1. Now we have all the characters that make up the language of computers. The CPU then uses Hardware languages like VHDL to operate these 0s and 1s. This is how Physical things do software work.
This video series is fantastic ! The animations, production quality are top-notch!
Amazing.
Amazing work
Cause this 2 videos, I want read more and more about this subject, so thk.
Thank you very much for these kinds of videos, truly amazing.
This was a great, short and in-depth explanation with awesome animations & examples. Please make more such videos.
Excellent! :)
beauty!!!
Awesome video
