M1 Ultra 'Mac Studio' Weighs 2 Pounds More Than M1 Max Model

The M1 Ultra version of Apple's new Mac Studio desktop computer weighs a full two pounds more than the M1 Max version.

Apple explains why in a statement provided to The Verge...

They have the same 370W power supply. The additional weight is due to M1 Ultra having a larger copper thermal module, whereas M1 Max has an aluminum heatsink.


Early speculation was that the M1 Ultra needed a bigger power supply or more powerful fans but that's not the case. Copper weighs about .324 lbs per cubic inch compared to aluminum at 0.098 lbs per cubic inch. That mean's the aluminum in the M1 Max model weighs around 30% of the copper in the M1 Ultra model.

We'll get a much closer look at this thermal module once teardowns arrive. The Mac Studio will be released on March 18.
