With the OLED vs External Panel, we can estimate the power draw of the panel, if we assume we used up the entire stated battery capacity in the runs.
Zenbook 14:
With the internal OLED panel, the device drew an average of 7.087 for 10.6 hours. 10. 6 hours 7.087W = 74.98046Wh. That's 0.03% below 75Wh.
With the external panel, the device drew an average of 3.679W for 20.38 hours. 3.679W 20.38h = 74.97802Wh. That's 0.03% below 75Wh.
That means the OLED drew 3.407W of power.
The OLED's power draw is 92% of that of the rest of the system.
Zenbook S16:
With the internal OLED panel, the device drew an average of 7.009W for 10.7 hours. 10.7 hours 7.009W = 74.9963Wh. That's 0.005% below 75Wh.
With the external panel, the device drew an average of 2.655W for 28.25 hours. 2.655W 28.25h = 75.00375Wh. That's 0.005% above 75Wh.
That means the OLED drew 4.354W of power.
The OLED's power draw is 164% of the rest of the system.
I couldn't find a reputable source, but chatGPT suggested somewhere between 20 to 50% more power draw for an OLED panel compared to an IPS panel. If we go with a 20% reduction in power draw, an IPS Zenbook S16 could be drawing 3.4832W for its display, for a combined total power draw of 6.1382W. With a 75Wh battery that would get us to 12.21 hours or 732 minutes - 7 minutes shy of the Surface Laptop 7.

Good on AMD for offering meaningful improvements in performance and efficiency. Zen5's fizzle had me worried. Of course you can't seriously consider buying one when Lunar Lake is nearly here and if leaks and claims are even mildly accurate it should have an edge over Ryzen AI. Decent chip, but the timing might be it's downfall.
When it comes to X86 vs ARM, the price alone makes the Snapdragons questionable, when you add in the compatibility issues it's a hard pass for me. You'd think Qualcomm would want to launch with a bang by pricing them well knowing there were going to be compatibility issues, but they seem to think they're Apple and can charge that Apple cultist premium. Sorry Qualcomm, literally _no one_ is a cultist for you like Apple's fanboys, and you're brainless money grab turned what could have been a luke warm reception into a fizzle and a fart.

Hey Gordon! or anyone else, I'm curious about something: I've never seen anywhere Meteor Lake tested trying to use it in the mode of only having those 2 LP E-cores active. Any insights on that I believe that's because Windows is so bloated that only when you're actually doing nothing the CPU goes into that state (with the PE cores chip shut off), and for anything else, the main cores have to light up.
Still, I am curious of some actual tests and numbers.
And, of course, I'll have the same curiosity with Lunar Lake which will also have the possibility of only having the E-cores active, and the whole P-cores chip to be shut down. With 4 much better E-cores, it should actually be a frequent state for Lunar Lake, not rarer than a hurricane.

At 25:00 something seems odd here!!! If this is accurate, is the panel on the Snapdragon just way more efficient or not really running at the same spec It's also sus that Microsoft didn't have an HDMI port. Are they hiding something It would be curious then to try doing this test from USB to HDMI on all of these just to get an idea if whether the USB to HDMI is using a lot more power.
Edit: Oh I see, the Snapdragon laptop is using that more power efficient IPS. Ok that would be more power efficient but the image wouldn't be as nice.

Some very solid conclusions. Snapdragon still a niche buy especially when you consider the iGPU performance is grim. It’s worth it you know your applications will run on it and you want the battery life and unplugged power in which case consider that a lot of reviewers tip the X Plus over the X Elite for higher efficiency. Zen 5 isn’t quite as big a step forward in battery life and performance per watt as the hype suggested. The head to head against Lunar Lake in thin and light laptops will be very interesting to see.

Hi I am a Test Engineer. Your test is Real not Realistic because realistically, no one will ever reproduce this test.
Also it's not a consistent benchmark.
I can automate a Realistic test for you. Record and send me a video of you doing the test once and I will automate a script for you.
We can later test the test and see if we can fun reproducible results.
Reach out to me and we could figure out the details!

A better way to compare would be a battery size normalized runtime result. Specially since we aren't comparing laptops here and we are focusing on the chips. Yes yes the panels are different but you can't have it all. For me looking at wow ryzen is leading with 78Wh vs qualcomm with 54Wh means almost nothing unless I care about that specific model of laptop in the test.

If you use OLED and you switch to dark mode/backgrounds, you essentially get equal or better power usage compared to an IPS, with better quality screen for when you watch movies. I get 14 hours average runtime on my oled Snapdragon laptop based on powerfg. If you are unwinlling to use dark mode then you should NOT be buying an OLED laptop and expect decent battery life.

Just a note on the graph showing the WebXprt 4 run: instead of using phrases as more spiky, I reckon a distribution would be more meaningful.
You set a reasonable bin width (2W 5W) and then, for each power segment, you show the sums of how many units of time each laptop spends at a certain power range.

That difference between internal panel and external panel is so high that it has to be suspicious. Is there no chance that it's getting some power back through USB-C (maybe 5W or so), something which is enough to drastically extend the run time but not enough to prevent it from eventually dying

now i need amd to give me a chip for beefy laptop,maybe 6 zen5 with 6 zen5C core.That would destroy the performance laptop market
also dear windows cpu maker,please ditch the AI crap.Follow apple,skip those AI nonsense for more cores or better battery

Ryzen AI 9 HX seems good. I've gave my custom build to my brother and have been maining Mac mini M2 16GB for a year now. I need a laptop but only Lenovo has good support in my country. I wish I can get a Ryzen AI 9 HX in a ThinkPad model, maybe a T14.

CINEBENCH is only fair when comparing x86 vs x86.
CB23 uses ZERO arm64 itrnincsics
CB2024 only uses NEON
MAXXON caps arm64 performanc on purpose not implementing SVE-SVE2 and SME.
GET RID OF AVX2 and AVX512 lets see how x86 does

And I was thinking at the beginning: Why not just plug in an external monitor to eliminate the internal screen And he did it. Ok one graph that I was missing was normalize the external monitor numbers to battery capacity.

In canada 0 of these laptops exists.
They are still delaying the pushout of these laptops - AMD is THE WORST at releasing Laptops. You can just add 1 year to release date every time they release a laptop series.

The performance of these machines versus my MSI gaming laptop is insane, four to five times better battery life and CPU performance is better across the board. Wild. Thanks for the thorough comparison.

Would love to see newer asmedia USB 4 thunderbolt 4 certified chip on most laptops with amd. Strix point isn't available in India. Then again Zen 5 power efficiency is good. I went with Zen 4 8840hs

It's a bummer the Qualcomm based laptop featured an IPS screen. That most likely influenced the battery life quite a bit unless the OLED laptops used black color scheme across the board.

those screen test is brutal. if my laptop is the only windows device i have, i will choose OLED, however if my laptop is only a secondary device i will choose IPS for battery life.

should have included one with 8840u because I suspect it is more efficient. these cpus are only differentiated by their process nodes.
intel -7nm
amd/qualcomm- 4nm
apple - 3nm
