This is a seriously fantastic video result. You can use Low Power Mode on the M2 Air and it results in drastically lower temperatures when maxed out. It uses a tiny amount of power compared to using the performance cores.

Max Tech, running the M2 MacBook Air on just the efficiency cores

I think that we discussed what a Mac with six efficiency cores would look like. This is the closest thing to that.
50˚C is not "insanely cool", haha. Imagine if ambient temp was 50˚C (not F). It's much cooler than 100˚C of course, just not insane.
50C on a fanless cpu at sustained full speed is really impressive to me
Is it insanely impressive to you
I was just pointing out his hyperbole. Also 50˚C is not at full speed 
That‘s nothing new. You can do that on the M1 as well. In fact, the M1 iPad pro can game very well on the efficiency cores alone. Even Genshin Impact runs on max settings without getting lukewarm for hours.
it is not full speed of the efficiency cores?Is it insanely impressive to you
yeah but the efficiency cores between M1 and M2 have much more improvement than the 'performance' cores. efficiency cores is where Apple silicon really nuke the competition.
It is the full speed of the e-cores
They should compare energy usage (power*time, (Ws, J) instead. It will be even more impressive and easier to understand as it only one number to relate to instead of two.
Apple should have a mode called "high power when needed" such as export of videos and rendering. Could even be a user defined profile.
Due to this, M2 might be very usable in an iPad (Pro) if iPadOS 16 and apps mostly uses the efficiency cores and to less extent rely on the performance cores. Interesting reuse of the same SoC for different devices with different energy availability.

Yeah I agree it would even help the M1 Pro and M1 Max on days you doing light work like web browsing and terminal/coding work.
Also would be really great if their next M* Pro chip would have more efficiency cores instead of all those performance cores.
The way they talk makes me want to throw up. Such tabloid style drama. The same people bitch about how the Macbook Air throttles and omg is soooo slow and then make it even slower by doing Low Power mode (which then surprise surprise suddenly is totally fast enough!) Okay yea sure.
Sure. Apple needs to release new SoCs that aren’t faster than the previous generation. That’ll go over well.
When will Max Tech stop these toxic benchmarks? Rene and his loyal followers are outraged.
You can make it faster with bigger and faster effiency cores, don't have to go all in on full performance cores.. It's a trade off design.
Almost as if you forget that this are laptops and not desktops.
Do you really want a 16” MBP that doesn’t have the highest performance possible? Better battery life vs performance makes sense in a MBA but not in a professional mobile workstation.
Apple has a pretty good sense of balance when it comes to performance vs efficiency trade offs. They target all day battery life with a 100 Wh battery with the highest possible performance within that constraint.
Yes. I’ll try to create one later today and post it. I already have several shortcuts for things like turning on/off tap to click for example.
Does it work on iPhone as well? My 13PM is literally burning hot in this summer weather running games. I should just run low power mode all the time.
There's two chips you can have a middle tier chip with better battery and then a M1 Max with outstanding performance.
I believe the balance is fine and all we need is 3nm and the new M2 Cores efficiency cores on a 'M2 Pro' chip
So far that isn’t how Apple has been designing their chip tiers. M1/M2 is 4/4. M1 Pro and M1 Max have the same 8/2 (4/4/2) CPU clusters with the Max having more GPU cores. The M1 Ultra doubles up the Max. Apple could design a SoC that is between the M1/M2 and the M1 Pro but I don’t see that as likely.
I have a 16 that's always in Low Power Mode.
I wanted a larger screen and more ports but I'd be fine with an M1 CPU/GPU. Apple just doesn't give you a choice, though. If you want the nice package, you have to get the higher-end CPU/GPU.
