They aren't even close to performance per watt.

M2 Mini maxes out at 50w and when I do full loads it usually doesn't go above 40w.

It gets a Geekbench score of 2633 single core and 9750 multicore.

5800u is 1641 single core and 6451 multicore.

Significantly more performance at half the power draw. Likely 4x the performance per watt.

Does the performance per watt on a mini desktop matter all that much at this scale? Don't get me wrong, it's impressive what ARM is able to pull off, but unless energy prices are crazy high in your area I've never really understood why it matters all that much. Also, the 5800U is 3 years old at this point. Hardly a fair comparison.

TBF In California as of the new year, energy prices are in the range of $0.40/kWh - $0.52/KWh (depending time of day, with 4-8pm being considered peek). In the summer the rates are higher, with peek being about $0.72/kWh.

The 5800u is a 25w chip, though.

The MX chips are ARM so the idle draw is probably better on the Mac, but for most tasks I don't understand how the Ryzen would be disqualified. It's probably the best low-power x86 solution on the market right now; you're missing out if you haven't seen what the Steam Deck can do at 10w.
