The MaxTech guys brought up an interesting point today in their MBP reaction video. They noticed that the MBP tech specs specifically for the 16" model specify a additional 0.1 lbs of weight when selecting the M1 Max chip vs. M1 Pro. They thought the added weight can't possibly be just the chip getting heavier so maybe it's a slightly better thermal setup. I believe this.

Here's the problem: the 14" MBP with M1 Max weighs the same as the 14" MBP with M1 Pro... implying there is no difference in anything except the chip, not the case (seemingly) with the 16".

They theorize the 14" might throttle quicker than the 16", or that there is some slight performance discrepancy between the 14" and 16" MBPs, something Apple didn't talk about in the press release.

Obviously this is speculation until the laptops can actually be tested but did I miss anything in the marketing material that explains this? What might cause the weight difference between the 16" M1 Max vs. 16" M1 Pro.

They say there is a 0.1 pound or 0.1 kg difference. But 0.1 pounds is 0.045 kg. Apple doesn't give the weight exactly and what we see here is imho a rounding problem.

The m1 Max is definitely a bit heavier than the m1 pro. I also suspect that the m1 pro has only 2 memory bars and the m1 Max has 4. That would fit to the double memory bandwidth.

So I assume there is no better cooling solution for the m1 max.


I don't know if there will be any problems with throttling, but if there are, the 16" will handle it better.

It could bring better fans on the 16" as many people have been discussing in another thread.

So what's the answer in real life?

I've been watching videos on the new laptops nonstop this week and it seems like thermal throttling isn't an issue since the chips are just so much more efficient (unless you're running intense tasks/programs all day) BUT The Verge released their in-depth review today and they reported (& Apple confirmed) that extra GPUs does drain the battery a bit, whether they're idle or active.

So all-in-all, pick the chip that works for you! Battery life is super important to me especially since the 14" has the smaller capacity so I feel validated in my purchase :)

Do you think Apple unnecessarily increased the weight of the cooling system if it didn't provide some benefit?
Has it been established that they increased the weight of the cooling system between the 16" Pro and Max models?

Yes, the Max on the 16-inch has a larger and thicker heat spreader plate covering the SoC package.

On the 16 Max, there is a large copper chunk on the chip which interfaces with the heatpipe. On the Pro, this chunk is much smaller along with the surrounding aluminum memory heat spreader.

Is there link where I can see it ?

wondering if left one is 16 pro and right one is 16 max
