5 Minutes on Tech: Intel 8th Gen CPU – Worth Upgrading?

Lisa Gade covers the new Intel 8th generation CPUs that are soon shipping for Ultrabooks. These are called Kaby Lake-R and double the number of CPU cores from previous Core i5 and i7 15 watt CPUs (UHD 620 graphics are basically unchanged from 7th gen). Intel claims they’re 40% faster— is that true? Is it time to upgrade your laptop? Lisa benchmarks them to find out.


Arctic Fox says:

Good info but im really wanting to see how these stack up against the amd ryzen 2500u and 2700u.

Nick Hippen says:

I’m still using a 4th gen i3. I think it’s time to upgrade now…

KO Mahgoub says:

Nice review. I would appreciate if you can do a review of mini-PCs. I would like to buy one with decent performance.

EL EL says:

If < 1 Ω

Dan K says:

Not worth upgrading — got it

Made In Machines says:

When will we see these 6 core laptops?

kevin9089 says:

Hello Lisa do you know if Lenovo is planning to lunch core i8 in Lenovo thinkpad yoga 370 because I have been waiting to upgrade my toshiba r630 4th gen 13 inch laptop. Any advise for my next laptop because I want to buy a good portable laptop ..

Qwertworks says:

mobile tech review is so awesome!

arnab bhowmick says:

Can you please explain me Intel’s new naming policy for mobile and desktop cpu? After the 7th gen

Ronan Harris says:

Just upgrading to a laptop with i5 7200u a month ago. These 8th gen chips doubles everything for real, wtf is wrong with me.

TabalugaDragon says:

hey I have a question. program called Throttlestop can completely remove throttling from low-powered cpu-s. Is it possible on the new gen cpu-s as well so it wouldn’t drop frequency? and heat issues can be solved by undervolting. Therefore we’re getting a perfect processor.

Marcelo Avalos says:

Do you by any chance have some insight about the 8th gen 45 watt laptop processors?, I’m really interested in what are they going to be!

tuberoako777 says:

Where’s the i3 8th gen for laptops?

Terry Tigner says:

By the way, the new 15’ Surface Book 2 packs the i7-8650U and the GTX 1060 and should be a compelling device for windows ink lovers!

Justin Lim says:

Hey Lisa and fellow youtubers, would like to ask what a better choice between two laptops, (A) Dell 14 7000 7472 with a i7-8550U, 16gb ram, MX150 gpu, 14 inch screen at 1.65kg, or (B) Lenovo Yoga 720 with a i5-7300HQ 16gb ram, GTX1050m-2G gpu, 15.6 inch touch screen (digitizer) at 2.0 kg? I can get the dell for slightly cheaper, and I like the lighter weight and outlook, however the Lenovo has a full digitizer touch screen and also usb type c port that allows charging, even via power bank! My uses would include quite heavy video editing and gaming. The main thing putting me off the dell is mediocre battery life, as it’s identical model the 7460 which has a 7th gen i5 reportedly has 3-6 hours battery life, so my next question is would the 8th gen icores in this same laptop mean a much battery life?

tlalotoani says:

I own an i7 4770s PC, and not going to change it for at least 2 years

GoGee says:

Wait for the AMD Ryzen mobile processors with integrated graphics. This will shoot down all of Intel chips that’s why they are currently in panic mode.

MIke White says:

Fabulous detailed comparison !! Thanks Lisa for breaking it down for us.

mdwm says:

lots of good info for a short duration video, you have my subscription 🙂

Stijn Algoet says:

Hey Lisa

Do you think the 15inch lenovo yoga 720 is still worth it (with the 1050) after the release of the 8th gen ultrabook cpu’s? Do you think they will refresh it soon? My yoga 3 14″ with i7 and gt940m just broke and I’m looking for something new that I can do some light cad-work on (thin and light of course) between 13.3 and 14inches… Do you think hd 620 graphics is enough for some light cadwork?

Lucas Haither says:

Oh boy, it seemed like a very good boost and I just bought a laptop 7th gen

Nate Chan says:


RunFar SR says:

What software that can Turbo boost your laptop cpu ?! Can anyone tell me ?!

Raju Gupta says:

I5 8250U vs I7 7500U plzz tell me which is better?

Kenichi Mori says:

元 Gen

SteelCity1981 says:

thing is the 8th gen 8550u gen can’t match the 7th gen 7700hq or even 6th gen 6700hq in multithreaded performance when all cores are bring used, due to its 1.8ghz clock speed. and that’s to be expected with its 15w tdp. so if you’re a gamer youre much better off going with the 7th gen 7700hq over the the 8th gen 8550u.

rodolfo toyoken says:

me still using 3rd generation cpu laptop with 4gb ram …. use to play rift online and world of tanks at 2 to 4 hours playing everyday and still kicking

Magdalena Huber says:

aim something bottom worry retain specialize fiction voter regarding.

myrang3r says:

The base clock speeds could probably improve with newer generation cpus. The 1st gen core i7 mobile quad cores were also sub 2ghz but with sandy bridge they already clocked them over 2ghz.

Mehmet Filiz says:

*I can’t imagine 21th gen specs*

advait dawane says:

I want to buy a new gaming laptop. Should I wait for 8th gen i7 gaming cpu or should I proceed with i7- 7700HQ .. please guide me

maxlol0 says:

me still using the i7 3840QM ivy bridge 45 watts paired with a gtx980m. kicking strong still in full HD gaming.

Kevin Xin says:

Lisa. I have been asking myself this question for so freaking long and now you’ve answered it all. On sites such as “userbenchmark”, the 8650U is roughly the same speed as the 6600hq. I was like wtf that can’t be right, right??? That’s so OP. They are judging the CPU completely on their cores and peak clock speed, so yeah of course they look like the same CPU on paper. But they are missing the most important part: the U CPUs are 15W. They can reach that 4.2GHZ clockspeed, but they can’t maintain that speed. I was so blown away by the Kaby-Lake-R cpu’s at first and now I’m not nearlly as impressed. Still great CPUs, still U CPUS.

Thanks for the review that was insane.

Ramón González says:

Moar cores but lower frequencies and less single threaded performance? WE AMD NOW?

Ire Min Mon says:

Lisa, thanks for doing the thing nobody else is apparently willing to do.
These are exactly the kind of reviews we need and I completely agree with everything you said, results are as I expected, but needed to make sure.
We still need the battery life tests in various situations, “coffee lake” vs. “coffee lake – R”, under full load, idle load or something inbetween.
I’d also love to see gaming results on “coffee lake – R” 15W CPUs + nvidia gen10 GPUs, just how high we can go before CPUs start throttling.

Gage Nelson says:


Made In Machines says:

With the fluctuations in clock speed you have shown from the new chips does that make them less stable and therefore more unstable for live work such as producing music? Are they more or less powerful than previous Kaby Lake quad cores?

the0glitter says:

There are cases where resistance isn’t futile even if it’s lower than 1 ohm, you lady just played yourself

Rolf Engel says:

Hello Lisa,
At 6:10min you are comparing two I5’s(7th and 8th gen) and the I7 HQ. How would the I7/U 8th gen sit in this graph?
Thank you in advance!

Nowell Valeri says:

This is an amazing explanation. I feel like I just went to a college class. Thank you Lisa!!

Jay D says:

Dope Ohm’s law t-shirt lol

John V says:

The shirt is awesome but check out those cool earrings too! I love triangles! I may get my lady a pair

FLOXshui Lee says:

Waiting for next year’s macbook pro

Terry Tigner says:

Excellent explanation! Lisa keeps getting better because she’s a sharp, seasoned, analyst- journalist. She has stayed the course over time and her experience continues to deepen while having a broad range of tech issues to address. Keep up the good work!
