Macbook Pro power adapter comparisons and questions.

[the8thark]

The 14 and 16 MBP (pro level versions) are the mostly same thing, just different size screen. Both have the full suite of BTO options.

So why then does the 16 have a higher watt power adapter.
67W or 96W with the 14 and 140W with the 16.

Does this mean the 14 will be clocked differently to the 16 or am I looking into this way too hard?

It is for quick charge and perhaps the more power-hungry screen. The 96w power adapter can barely hold the charge of a M1 Max at full load of both CPU and GPU, and perhaps draining power from the battery if the screen is at a relatively high brightness. If we look at the M1 we current have in different cases, they are 'clocked' same, but they are having different scaling behavior and will throttle in the fan-less models after sustained high load.

One complaint of the 16" Intel has been that it can draw more power than can be delivered over USB-C. I assume that is what Apple want to avoid by MagSafe and by having chargers with different power levels.

The new M1 Max have a 140 watt adapter.
That's fine since you can drive the notebook 100% full load indefinitely... (not like the I9 parts).

Nevertheless, I wonder the following: / (With the new power supply and Magsafe)

The Magsafe is connected to the adapter with USB-C.
Which standard does Apple use here ?
Is it the new USB-C PD standard that allows >240 watts ?
Or has apple modified this and is once again using its own standard?

I mean, designing a notebook that requires more capacity than the power supply unit can deliver is what happened to apple. ((what happened to the i9))...

Nothing would surprise me anymore.

Different parts require different power requirements.

The extra 2" needs to power extra hardware.

M1 Pro vs M1 Max have different CPU & GPU core accounts that needs differing power needs to produce the performance you bought for.

To keep things simple Apple includes the charger that will cause the least questions from their buyers and produces the wanted bought outcome.

 

[wonderings]

Once you go with the M1 Max for the 14" you auto get the 96w power adapter, I know I did for my 14" M1 Max order.

Yes. It's the new PD standard which supports voltages higher than 20v. AFAIK anyways..

The type c ports only support the 100w AFAIK. But can't test it right? I haven't seen the new PD standard cable

The 16", which can drive three displays in addition to its larger screen, has a higher potential power draw and a larger battery which require more juice to fast charge while running at full power.

I doubt that I use more than 30 watts in typical use (I would when traveling but I haven't traveled since getting it). What I do know is that that brick charges the battery really quickly.
