Correction: Apple compared M6 with M5 and M1

Rough Day's August 25 summary said M6 succeeds M4. Apple's announcement does not support that claim; its M6 comparisons use M5 and M1.

Rough Day's August 25 Tech & AI edition said the M6 succeeds the M4 generation. That sentence was wrong. Apple's August 25 newsroom announcement compares M6 with M5 and M1; it does not describe M6 as an M4 successor.

Apple introduces M6 and M5 Ultra for a big leap in performance and AI compute puts M6 in the new Mac mini and M5 Ultra in the new Mac Studio. Apple compares M5 Ultra with M3 Ultra. Those are separate comparison bases.

What the source supports

The announcement says M6 has a 12-core CPU and 12-core GPU, while M5 Ultra has up to a 36-core CPU and 80-core GPU. Its M6 benchmark footnote compares a preproduction Mac mini with an M5 MacBook Pro and an M1 Mac mini. Its M5 Ultra footnote compares preproduction and earlier Mac Studio systems.

Apple ran the tests on preproduction hardware and calls the results approximate. The page does not provide independent measurements or identify the competitive systems mentioned in one footnote.

The corrected record

M6 comparison bases: M5 and M1.
M5 Ultra comparison base: M3 Ultra, with an additional M1 Ultra peak-compute comparison.
Benchmark owner: Apple, using preproduction systems and approximate results.

The original edition remains part of Rough Day's published record. This correction supplies the comparison bases that its summary misstated.
