Thanks for the review.

Is there any info on the pwm on lower brightness settings? Does it get worse the more you dim the screen?

Also, is there temporal dithering going on?

I've noticed something, does they improve the respond time in this new model? because it shows better result than previous one. is this accurate? or just it tends to swing between the numbers.

macbook pro 14 m1

G/G is 58.4
B/W is 40.4

the new model macbook pro 14 m2

G/G is 35.2
B/W is 26.4

I hope these number is accurate.

   

70 watt-hours is capacity...not max wattage.  A 70 watt-hours battery can deliver over 100 watts power.

Are the response times actually improved compared to the m1 Pro version?

I'm unsure if the big differences in your measurements between the 14 and 16 inch last time were due to the fact it's hard to measure because of the PWM flicker, and I wonder if it's the same thing this time

Super expensive laptop with PWM screen. No for me. I can buy much cheaper device which will be completely flicker free. Why Apple spends more attention to stupid emojis than their customers eye health.

Excellent review with fantastic pictures to boot! Especially the top aesthetic ones.
Apple's silicon seems to have lost its edge but I'm grateful it has pushed AMD/Intel to step up their
game even further.

Macbooks sadly are still not my thing aside from the slight overpricing aspect, the constraints and lack of customization puts me off. At this point is locked down to the firmware.

This is coming from someone that has a few hackintoshes.

Is that Libreoffice test not ludicrously faster than the competition? That can't be in an accelerated decode block I don't think, so what's the deal?

Is there any MacBook that you can buy today that is eyestrain free? I've heard that m2 air should be good but some people say it still has pwm and definitely dithering.

What the heck is Schenker? I searched online and all I could find were Sony Vaio laptops.

With the always used PWM, the response times are hard to measure. As we use a better osci compared to the M1 Pro review, the numbers should be more accurate. But look at the screenshots and judge for yourself.

Huh? Is something lost in translation? Author writes "The new MacBook Pro 14 also clearly outshines the AMD Ryzen 9 6900HX processor in the Razer Blade 14.". But in CB R15 the Ruben 9 6900HX beats the MB M2 Pro 14 by 10% and in CB R23, which is native for the MB M2 Pro 14, the 6900HX loses by only 4.5%. What gives?

Cinebench R15 is emulated (Rosetta 2) and thus slower

There is a reason why PWM is present, Dell XPS 15 or Latitude 9000-7000 or HP Zbook Studio Serie has no PWM on their Screen but the brightness is too high at 0 settings 32-36 cd/m²,(the exception is Laptops with OLED Panel) which makes it impossible to work at night or in low light room, (it can harm your eyes). I have Precision 5570, several XPS and Zbook Studio at work and I know. Macbook with 0 settings the brightness of the screen is only 2 cd/m² (means usable in all circumstances). I'm mostly a Windows user and now I have this Macbook.Usually people with glasses always need a brighter display when working on a laptop, that's because of eye problems.. at the moment there is no better display than the one on the Macbook. message to Notebookcheck, test the Display in all conditions, including in a dark room,For some maybe irrelevant details, but that's why Macbook pro makes it a special machine...

yep, the MacBook Air M2 e.g. is not using PWM

Surprisingly, in the reviews of the new Apple chips, there is not a word that they are on average 3 (200GByte/s) and 6 (400GByte/s) times over the speed of pumping in memory compared to X86.

There is not a single test for the real speed of memory in new makuki, although this is the most advanced memory on the planet in speed with a 512 bit of access controller, which is 4 times wider than on the X86.

I would like to see these tests to evaluate Apple's declarations in practice.

Because it is not clear to me - as with such a quick memory, the M2 Max does not significantly benefit from the new top i9 of the 13th series and the 7945HX from the AMD, which has traditionally 1.5 times slowly, even at a larger memory frequency with 128 bit memory bus access . What is proved in dozens of NB reviews.

If it turned out that the M2 MAX memory controller is really capable of pumping 300Gbyte/s+  this would simply mean an outstanding breakthrough against the background of Intel/AMD shame with their X86 platform.

In the CPDT "Memory Copy" benchmark (added pictures for external SSDs in the ports section), the MBP14 reaches 31GB/s vs 14GB/s of a Alder Lake i9-12900HK in the MSI Raider GE76 (DDR5-4800).

It is peculiar that neither last year (unless I am wrong) nor this year you reviewed the 16" M1/M2 Max laptops...why?

Firstly, these ridiculous numbers in no way refer to the memory controller test, and secondly, this data is not included in the review. I did not find.

Why is there no memory controller test? Is there really no analogue of AIDA64 under MacOS or another cross-platform memory test?

This is a very important declaration from Apple and needs to be carefully checked and compared with the x86 platform. If Apple is lying (and most likely it is), this will immediately be revealed in the tests.

The MBP screen is not OLED, it's mini-LED so Apple could use another way than PWM to dim the LEDs down. They just don't. Plus, the MBP PWM is 14800Hz at all brightness levels, not just low brightness (like the M1 MBA).

Hi.  Thanks for the very comprehensive review.  94% is the highest laptop score I've seen on this site, so I made this a contender in my purchase decision.  I dropped the hammer on a Thinkpad T14S Gen3 AMD (91% by a different reviewer on your site).

I understand that you have specific criteria to weight your reviews, but I wonder at the very high score for the MBP.  I went for the T14s because of 3 things:

- The availability of a touchscreen (no option on MBP)

- The swappable SSD (soldered on MBP)

- The price: T14s with 32GB RAM was $1830 CAD on sale whereas the MBP with 32GB is $4100 CAD and hard to find on sale.

The build quality (keyboard being especially important to me) sounds roughly equivalent, the MBP is 20% heavier and, although the IPS screen on the T14s does not fully compare to the high end mini-led of the MBP, it is matt and dims beautifully with no detectable PWM.   

Anyway, even though I question the relative scores of the two reviews, your reviews were extremely helpful in helping me make a decision.  So thank you again!

The m2 reaches 100w of consumption and the guy talks about 25w in the middle of the article, as if the chip was super efficient

How about talking about the real numbers and not what Apple counts?
