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 $350 of each other: $3,999 for the MacBook Pro M5 Pro (16-inch), 64GB and $4,349 for the Beelink GTR9 Pro, 128GB. Apple makes one and Beelink the other. 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 Pro (16-inch), 64GB pays back sooner at every level of use, so this is not a choice that turns on how hard you work it.

What the extra memory buys
The Strix Halo Beelink GTR9 Pro, 128GB holds 6 models the MacBook Pro M5 Pro (16-inch), 64GB cannot at 32k of context. The strongest of them are what the difference in memory actually buys.

The extra memory buys context as well. Of the 27 models both machines hold at 32k, 4 run to a longer window on the Strix Halo Beelink GTR9 Pro, 128GB: 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. Gemma 4 31B it reaches 256k there against 128k on the MacBook Pro M5 Pro (16-inch), 64GB, each the longest window the calculator offers that the machine still holds it at.

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.
