I think the more important distinction is what power limit the CPU is. For example, an i5-12600H series (45 watt) will crush a i7-1260p (28 watt) and the core amounts are different. Even stepping higher, the i7-12800HX (55 watt+ and 16 cores) will beat an i9-12900H (45 watt and 14 cores) while technically costing less. So be aware of the power series of the CPU as typically it is more important when comparing different kinds of laptops. If you are looking at strictly i5 vs. i7 in the same laptop, Josh’s advice is the best. Great video!

Battery life shouldn't be that different, either Intel or dell is playing with their driver software to make i7 look good than i5. 🤢

You were right Josh, I am shocked haha. Now, it would be interesting to see the difference between the i7-1260P and the i7-1280P which has more cores and probably even better binning :D

ok, that was actually shocking! usally the "twist" is that the i5 is better because i7 throttles itself out of the picture!

Some of these results defy sense and suggest testing issues (e.g., battery life differences between the i5/i7). I'd hesitate to make recommendations without more research or evaluating replacement devices.

As a retired test engineer I applaud your methodology. For most laptop manufacturers thermal generation and dissipation are nagging problems which results in power throttling, which results in performance reduction. The gamer laptops and some others have larger heatsinks, heatpipes, fans and better airflow.

There is definitely something else at play here: either Intel finally segmented the market with even more segmentation on their chips, or (more likely) Dell's power management IC is the one doing the segmentation. The weird thing is indeed the battery. I wonder if and when unlocks are found (such as from Throttlestop supporting these), if we will find that the i5 is effectively as good under the same thermal constraints these laptops allow.

I love how you back up your review with hard core data. You ran the numbers, compared the specs and judged the performance in real time. Comparing the exact same computers with only different processors makes the evidence hard to dispute. Thank you so much for this video

Regarding battery life - may be it's something with nature of the test itself. I reckon video playback is hardware accelerated and i7 has more iGPU compute units. Can it be that i7 runs more efficient somehow because of this? May be some other test, not the video playback, would give other results.

👍🏽Thanks a lot...I can now save my coins! No point in spending $216 for a 3%-7% difference; besides I'm not an gamer.

I have tried to go a different way - I try to opt for models with an i5 and a Nvidia or AMD graphics card instead of Intel graphics. I find that if makes the PC feel more responsive and I suspect it would offset the gains with the i7. I don't think it matters which AMD/Nvidia card it is but preferably with it's own memory.

Glad to see your results. This was not the case in your previous tests from last year, when the i7 was actually worse than the i5. It seems Intel improved a lot with its new performance cores+power efficient cores. AMD still beats the integrated Intel Xe graphics. Can't wait some laptop reviews with the new AMD Ryzen 6600U and 6800U + the new RDNA2 integrated graphics.

I would love to see if this comparison holds up with the processors in the 9315 version of the xps 13 (i5-1230U and i7-1250U)

Fantastic video. You're my favorite laptop reviewer, in part because I find you to focus on the most important things.

I wonder if the differences in thermals and battery life would still be in the favor of the i7 if there's a dedicated GPU involved (e.g. RTX3050).

That's truly astonishing results. If 12th gen i5 is not 50% cheaper, I don't see the point of buying i5. My laptop runs i7 and it is lightning fast.

As a clinical researcher, the standard for what constitutes "evidence" to the everyman is downright frightening. This comparison is laughably unscientific. Throwing around descriptors like “epic” and “walloping” just makes it even more incredulous. Performance benchmarks: Average of X runs? Would be important to see performance stability with consecutive runs. Temperature and fan noise: “I recorded a CPU max of 100C on both performance modes for both chips, so no difference there.” Missing: clock speed, fan speed, ambient temp, ambient noise, noise measurement distance, equipment, description of the load parameters. Battery life: “Best battery settings, screen 3 notches down for brightness”. Perhaps the most flawed of all the comparisons. Screen brightness should be calibrated using an objective measurement like lumens, not “notches”. Battery life is reported as a percentage when the devices all use different size batteries. At the very least you should discuss power consumption in terms of Wh or, more practically, total battery runtime under a specified load. What other background tasks/processes could have been running? Also, it goes without saying that performance benchmarks are meaningless to most users who just want a responsive device that can stream video and browse the web with good power efficiency. Who cares what the Cinebench score is? There is a distinct lack of truly objective and scientific technology reviews. Someone needs to do better.

I stuck my fingers in a plug socket and the result shocked me

I don't want to get shock.

Considering how close the i5 and i7 in the 11th gen (especially in the HP Envy series), i think something fishy going on in the 12th gen i5 chips

You are all missing the biggest point. Most operations take fractions of a second, so, for arguments sake, let's take an application that takes 1 second to open. A "massive 19% faster" means it takes .8 seconds instead. Is that even perceptible? For most people the answer is NO. Now take more common functions that take tenths or hundredths of a second and knock off 19%. See where this is going? There are very, VERY few tasks that will get perceptibly faster with a geewhizbang new faster processor. Exceptions are for those tasks that can be measured in minutes. CAD rendering, large program compiling, multitrack audio processing, video rendering and the like. Then, if a task drops from an hour to 49 minutes you're more likely to notice. The rest is just industry hype to get you to watch videos (because that's how the creators make money) and buy new hardware you don't need because that's how manufacturers make THEIR money. As a general consumer, unless a given "upgrade" is 100% faster than your existing hardware, you'll barely notice a difference if at all (other than the initial, oh its new isn't this wonderful placebo effect). Ask anyone who got a new computer between a week and a month ago if its as "blazing fast" as when it was brand new. The answer is most likely NO. The shine has worn off and you're back to the same old same old. Save your money, take a vacation instead.

You got the 2022 Zephyrus G14 in the studio?! Can't wait for your review! Feels like nobody has done it properly since the thing came out, but I know you will.

Shoutout to our guy giving us this video, even though he's got the virus and is tired. The same defectuous temperatures found in Dell XPS laptops. I don't get why Dell is not able to keep the temperatures under a decent value, but other people who are creating custom cooling (vaper chamber, for example), solutions for their laptops can. As for the i5 and i7, I find it a shame to have 4C/8T these days, given that AMD since the 4000 series gave 6C/12T on a cpu efficient laptop. Plus, I'd go all the way for the i7, no question about it. But only on XPS 17, who can mentain kinda decent temps.

Are the screen panels exactly the same? More expensive laptops often come with higher quality panels. In the case of panels this could mean a lower power consumption such as one of the newer low power panels. e.g. on Thinkpads you can often specify them with different panels at build time; one of those is a low power option. I don't just mean resolution but actual manufacturer and model affecting the power consumption.

We're here josh

The difference in RAM timings might result in a wide gap for memory intensive tasks, such as iGPU testing.

This was very informative. I'd love to see a comparison for the U series.

This is a great video and a fair comparison assessment. I'm a Windows 10, Azure, GCP, and data analysis kind of guy. Thus, the i-7 with Windows 10 is my choice. Especially using Dell Lattitude 7420.

Thx for your comparison - interesting results indeed. The i7 showed higher performance per watt in comparison to the i5. The reason I can think of is higher frequencies for a given voltage, because i7 are supposed to get the better quality silicon dies in comparions to i5. Last year you compared intels 11th Gen i7-1165G7 and i5-1135G7. They are, like the 12th i7-1260P and i5-1240P very similiar:, same core count, but the i7 has a larger cache and higher clocks. The i7 should use the better quality silicon. In last years comparison however the results where quite different. The i7 had no performance advantage. If I remember correctly sometimes the i5 even beat it. Which was quite odd to see. I think Hardware Canucks found similiar results. In the light of the 12th Gen comparion results, what do you think of results of the 11th Gen? How is it, that 12th Gen i7 is a big upgrade over i5, while in 11th Gen it almost didnt matter. They both are manufactured in intel 7 (aka intel 10 nm superfin). So I'm somewhat confused in the cause of the different results.

The power consumption of the M1 Pro is really spectacular. Truly best in class.

Great review...thanks Josh

I don't find it fair to compare to Apple Macbook Pro, which is almost double the price for similar specs. I have an older XPS, the 9310 with 4k oled screen, 16gb of ram, which costed 1400 euros, and m1 macbook pro similar specs was around 2300. I will keep on Dell XPS, with i7, changing it when current one becomes really used. PS, my battery still allows me almost a full day of work on it.

Alder Lake is probably starved in the cache department, which would explain why one of the biggest changes for Raptor Lake is the amount of cache available for both P-Cores and E-Cores; and also (probably) why Intel clocked ADL way above its efficiency sweet spot to make up for it. It would have been interesting to clock both CPUs at the same Frequency to test the effects of the difference in cache sizes. For the GPU results it’s not surprising that the i7 beats the i5, beyond the difference in EUs (i7 has 96 EUs vs 80 EUs for the i5) the L3 cache is shared between the CPU and the iGPU and those 6MBs go a long way in helping to relieve the memory bandwidth starvation for the iGPU.

Sir please give your review on M2 air. My mom only trusts your review. Your accent and slow crisp vocabulary are amazing for non native English speakers.

Hi Josh, thanks for your videos, really quality content. Have you ever experienced any issues with a sleep mode in XPS laptops? I.e. with Windows modern standby on Dell laptops? When you close the lid, put it in a backpack, then get it out in a few hours and find it extremely hot and with a drained battery? If yes, do you have any piece of advise on that front?

Thanks for your great review of those processors and stay well, Josh!

Thanks for this video, Josh! I hope you could still do videos like this for the other laptops you're gonna review in the future (that is, if you could get to test both i5 and i7; or Ryzen 5/7, etc.). Cheers!

I recently bought an Acer Aspire 5, i-5, with Iris Graphics and a 14" display. It came with 8 GB of DDR 4 RAM. I immediately upgraded 1st to 12 GB and then to 20 GB of RAM. And I installed 1TB SATA SSD. The laptop boots to Log-In screen in 10 seconds. With 12 GB of RAM Windows Performance Monitor showed 45% of resources used at idle. Now with 20 GB or RAM, Performance Monitor shows only 25% of resources used. At any rate, it does everything that I could ask of it, even in two different languages. Cheers. I like my Core i-5.

How is the i7 drawing more power and draining less battery at the same time?!

great video josh thanks i hope you will do ryzen 6000u series laptops i understand linux runs very well on them well i hope they do i want to buy one by the end of the year

Thanks for a very important comparison. Great video and very important information.

Never thought I'd see Logic review laptops

great video Josh. i just purchased china market only Thinkpad Neo 14 AMD Ryzen 6800h. Amazing laptop. Ryzen 6000 Zen+ is smoking 12th gen Intel overall with RDNA2 graphics. pleass review some Ryzen 6800u or 6800hs or 6800h laptops.

Hey, do you think these results would be similar when comparing i5-1230U with i7-1250U (processors of the Dell XPS 13 9315) ? Are you planning on comparing them ?

My first though was silicon lottery: the i7 is a higher binned CPU and is overall more efficient. Although I don't expect it would make such a big difference so maybe there is something else going on. Still, you'd need a bigger sample size to check this out. Maybe Intel or Dell are intentionally messing with these i5 CPUs, that would not surprise me either.

I'm gonna guess it is a binning issue. The specs of the i5 vs the i7 would make me thing the i5 is an i7 that couldn't hit those frequencies within Intels desired power envelope. The i5 likely requires slightly more voltage when turbo kicks in pushing it outside its efficiency window. Simply the i7 is a better piece of silicon. I would also point out that Intels turbo is very ham fisted in its approach to getting max speed. It tends to crank voltages and produce more heat than necessary. Of there was some way in manually controlling the voltages you could in theory set better values for when the processor turbos getting lower heat generated and less battery usage for the same performance (maybe increased performance as it can turbo for longer)

Excellent research!

Very insighful video Josh! Would love it if you could make a video about the 2022 Zephyrus G14 and G15 laptops!

Yes, I got a 1260P laptop. I paid £300 more but I knew it was the better choice over the 11th gen i5 chip

Get a good USB 3, docking station, and a dorm fridge. Punch a hole through the side of the fridge, and run the cord to the docking station. If the laptop generates heat the fridge cools it off. You can run the machine as hardcore as the settings let you, and grind some data.

If you want Excel to calc fast though, clock speed is the biggest thing. Excel is shitty at using multiple cores for anything other than saving, graphs, peaks, etc., true separate processes that can be sent to a different processor. For actual calculations, clock speed is all that really matters. Faster memory also helps a bit.

Josh! :) Can't wait for comparisons with intel meteor lake laptops, I've heard good things about them. PS: you forgot to hypothesize why the i7 performed especially in battery life. OR did i miss something?

Great video, said what needed to be said and no bullsh*t, Subbed👍

Excellent research and delivering extensive knowledge. It will help a person who confuses choosing a laptop. Thank Josh

If you normalise for the size of the battery, the XPS is at more like 50% battery, so not too bad - still more improvement needed.

makes no sense why an i5-1240p uses more battery than the i7-1260p , the only possible explanation is that ram uses a lot of power and the bigger cache of i7 limits ram access, has someone another explanation ?

This video was very helpful and made a direct impact on my considerations.

Yeah mate, the iGPU for intel is mainly for Quick Sync. Stop comparing stuff that shouldn't be compared.

This is a good discussion, I've heard the thermal throttling negates the difference in performance pretty quickly. I have a ThinkPad Extreme gen 2 with an i5, and it seems kind of slow. But I have an Asus with a Ryzen 7 which makes everything else seem slow.

Why didn't you test with a u-series i5? The stated power draws for it much lower than the i5p, which has the same stated power draw as the i7p.

Good summary. Thx

Absolutely great videos. Thanks Josh

Why do people tell me that i7 processors get hot and then throttle to i5 speeds?... Any thoughts?...

Get well soon josh!!

8:32, you may check the battery life by putting same value for Intel speed shift in throttle stop. May be it's value is put higher to make i7 look good .

Thank you so much for making this video :o) What about i7 vs i9?

Upon Dell support telling me that my Java needed upgrading after telling them that the numeric processing failed a simple test, I have never considered a Dell, again.

Wait, do the battery life results apply to R5 to R7 laptop comparisons? I bought a R5 5500u specifically because I was hoping I could get some benefit over the R7 5700u on the battery side.

Fantastic video! Would you consider doing one for h series laptops?

Woooo, new video! 💙

I made up my mind to buy i7. Thank you so much.

My i7-6600u idles at 35-40 degrees, i5-8250u idles at 55. Stress test is 60 for i7, 70 for i5. I guess either it's because the i5 has two extra cores, or they set i5 fan speed to allow higher temperature. For me, lower temp translate to stability, and reliability. Although it's two generations older, still relying on the i7-6600 for most daily tasks.

If you have a necessary non-gaming application that pushes a laptop that hard, I'd like to know what you do for a living. $150 doesn't sound like a lot to some people, but for many it's what they spend for a weeks groceries. A dedicated video player and game console would cost a fraction, would be more cost effective for continuously playing movies and games, and the power savings would be enough for family-sized displays.

i5 Vs i7 (P Series) 13th gen 🙏🏻

Not all the software use the multiple cores except the OS which is not known by many. Only few sofware which require intensive CPU uses additional core explicitly. I always sugges to stick with i5 instead of spending more in getting i7 without having these metrics, thank you for these.

These laptops are too beautiful, I hope they transfer this design language to the 15 and 17 inch models.

This is the question you need to answer on every intel generation. Power: Performance Weight Build quality Hot or cold temps to use Battery life Great work!

I used 2 ThinkPad's yesterday, one with Ryzen 7 pro 5850U and another with intel i7-5600U. And you know, not that much difference for office / home user tasks.

I loved every review, non biased and promising

You can do not only basic but also advanced video editing on the iris xe igpus thats literally the reason for their existence besides the uhd series

Can you do a video comparing latest i7 & rizen 7 processors as well?

I chose the i5 processor. The upgraded i7 was a $200 price increase and I decided just wasn't worth it. Got an HP Pavilion eg-200 , upgraded the ram to 16GB 3200MHZ, and a higher quality screen. Stuck with the base 256GB M.2 NVME since I could upgrade that myself down the road. Paid $680 after taxes with a $400 discount and am very happy that I chose that custom build over the laptop I had in my cart for $923 last week. This laptop will be used for school work + programming. Im currently on a 2017 HP i5 and the computer works fine. Just want better performance and screen color mainly.

The i7 U/P has 16 more EU in the iGPU compared to the i5, so that would explain the better graphics performance

This is great now all we need is for Lenovo to actually market some of their legion laptops instead of just promising us that they’re coming. It’s now almost August and haven’t heard or seen anything from them, particularly Legion 7i

Dammit, I'm so shocked - thanks for warning me, thought you were joking!

did you investigate the battery difference any further then running the test again? feels very odd that 2 supposedly identical battery's can preform so differently even with the upgraded cpu

You are using Dell XPS 13 Plus in your demo of i5 Vs i7. While 12th Gen i5 has comparable performance to i7, you don't get 32GB RAM with i5 in Dell XPS 13 Plus and you cannot upgrade it later as the RAM is soldered on the mainboard.

Do you think I can apply there resilts for 13th gen

Josh, I'm thinking of ordering an XPS 13 Plus with the 1280P processor, maxed specs, but full HD touch panel. I have a 3070 Ti eGPU and 40" Dell 5K2K monitor when docked and want good battery life when mobile. I use office productivity and some stats packages. Mac is out of the question for me due to software constraints. Thoughts? Or other recommendations?

Are we getting a review of the new G14 soon?

Which one is better? i5 120U or i7 150U ?

That was incredibly helpful both for buyers of new machines and of used ones. Thank you so very much for generously sharing this work. Your mother should indeed be very, very proud

In many cases the i7 will do about 25-33% better than a i5, but only if you load up all the cores with back to back work. And that does not happen most of the time. Single core or "few" core performance ends up often being the same between the i5 and i7. Save your money. Also, I see DELL here. Get 8GB and 2x16GB sticks elsewhere, and you end up with 32 gigs for the price of 16, lol.

The results may have shocked you but I was aware of this battery life "phenomena" already. 😊

Which laptop is best for programming windows desktop apps and using high cpu/ram visual studio etc. In 2022

directionally correct indeed

Tha Varus - human performance limiting engineering. :-)

DID YOU TEST THE 2022 MODELS OR THE OLDER ONES SINCE BOTH MODELS ARE AVAILABLE?

Which display did those two units have - interested to know given battery life - was that the 3.5k oled?
