The 65 W beside the Mac mini M6, 32GB is a stand-in, not a figure for that machine: the data borrows it from the nearest hardware it does have, and the machine's own page names which and why. So the two figures above are not like for like, and the electricity in its pay-back here is priced from a borrowed number.

The same money, two different machines
These two cost the same: $1,299 for the Mac mini M6, 32GB and $1,299 for the Radeon AI PRO R9700, 32GB, card only. Apple makes one and AMD 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. The two are less equal than they look: the Radeon AI PRO R9700, 32GB's price buys the card alone, so read its column as the cost of the part that does the work on top of a machine you already own.
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 Mac mini M6, 32GB pays back sooner at every level up to 4M tokens a day. Above that the AMD Radeon AI PRO R9700, 32GB does.

The extra memory buys context as well. Of the 19 models both machines hold at 32k, 8 run to a longer window on the AMD Radeon AI PRO R9700, 32GB: 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 Mac mini M6, 32GB, 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. The Radeon AI PRO R9700, 32GB is priced as the card alone, so add the PC around it before comparing it with a complete computer. All seven cards here are ranked by what each one holds.
