What is Hyperthreading?

Because of Hyperthreading (or should it be Hyper-threading), many modern CPUs have "threads" as well "cores". Normally there are double the number of threads than cores. But what does it all mean? Does it improve performance? And is it better to have more cores than threads?

The airport part was the best hyperthreading explanation I've ever seen. Good job

[supersu]

That example was really made it easier to understand. Thumbs up from my side :)

This channel is arguably one of the best when it comes to explaining computer concepts. Gary you the best.

This was a really great explanation. Love the fact that you took the airport example and in the end compared the 6C/12T vs 8C/8T speed differences.

There has been a lot of talk around the next gen Intel CPU with "only" 8C with no HT vs the current 6C/12T CPU. For some it does not make sense, while for me it makes perfect sense. :-)

Keep them explanations coming!

Great video, like the drawings, amazing as always - thank you Gary 😇

[MuhammadAhmed-whkv]

Again .. what a great demo Gary .. really good job

[StrikeFreedom]

Helpful as always, thank you Gary Sensei.

I just love your explanation 😊 Sir Gary

How have I not heard of this channel. Actual useful, correct info on technology he deserves over a million subs.

Awesome explanation as always. This channel is so underrated. Hope it gets larger than other so called "tech" channels that talk about things like how animation in one phone is 10ms faster than it is in another phone. One suggestion: please don't use handwriting animation (with fake hand) - it is little distracting. Thanks!

[shahedzaman]

This channel should get a million sub ASAP. so through so good video. good job man. :)

Omg, airport security checks example…. How brilliant! You are gifted at this, Sir! No one explained this better than you. I am preparing my CompTia A+, I got to subscribe your channel

The best hyperthreading explanation I've heard so far, thank you! Thumbs up!

[taidee]

Wow, the best way to explain these CPUs ever. Thanks again Gary for the great work.

[viazel]

Thank you again Professor! Wonderful video... lesson learned!😎

[BillCipher]

the example with the airport security check is just simply awesome. thank your very much :)

This channel is underrated. Subscribed.

What a great analogy on the airport queue!

In short : *4C/4T* is better than *2C/4T*
