Neither power figure above is measured on the machine beside it. Both are stand-ins borrowed from the nearest hardware the data does have, so the gap between them is not a difference between these two machines. Each machine's page names the figure it borrows and why. Every pay-back figure on this page prices its electricity from these numbers.

The same money, two different machines

These two cost within $100 of each other: $2,399 for the MacBook Pro M5 (14-inch), 32GB and $2,499 for the Mac Studio M5 Max, 36GB. Both are Apple machines, but a MacBook Pro and a Mac Studio are two different machines rather than two sizes of one. Every other head-to-head on this site holds a piece of the hardware equal and asks what the price gap buys. This one holds the price, so the row that usually carries the answer is the row the two machines agree on, and everything under it is what the same money buys twice.

How much use it takes to pay back

Everything above is at 500k tokens a day. Pay-back moves with how much you actually run, so here are both machines on Qwen3.8 27B, the strongest model both hold, at the five levels of use the calculator names. The MacBook Pro M5 (14-inch), 32GB pays back sooner at every level up to 4M tokens a day. Above that the Mac Studio M5 Max, 36GB does.

The extra memory buys context as well. Of the 19 models both machines hold at 32k, 7 run to a longer window on the Mac Studio M5 Max, 36GB: the weights are a fixed size and the KV cache is not, so what the weights leave spare is what a longer context grows into. Qwen3.6 27B reaches 128k there against 32k on the MacBook Pro M5 (14-inch), 32GB, each the longest window the calculator offers that the machine still holds it at.

The MacBook Pro M5 (14-inch), 32GB is also head to head with another computer: Mac mini M5 Pro, 48GB. With the same machine at another memory size: 16GB.

The Mac Studio M5 Max, 36GB is also head to head with another computer: Mac mini M5 Pro, 64GB. With the same box and the bigger chip: 48GB. With the machine it replaced: Mac Studio M4 Max, 36GB.

The assumptions behind both columns

Both columns use the same usage: 500k tokens a day at 15:1 input to output, 32k of context, $0.17 per kWh, and today's API prices held flat. Speeds marked estimated are worked out from memory bandwidth rather than measured, and pay-back scales with them. Change any of it in the calculator.
