Apple has quietly corrected the specifications of its new Mac Studio, removing references to PCIe 6.0 from its promotional material. Spotted by MacGeneration, references to PCIe Gen 6 have been erased from press releases for the new M5 Ultra Mac Studio. The releases now describe a 'next-generation SSD architecture' instead, though the French version still mentions PCIe Gen 6.

Apple didn't explicitly state which PCIe specification the device uses, but it's likely PCIe 5.0, as seen in the M5 Max MacBook Pro. The PCIe 6.0 standard, announced in June 2019, offers 64 gigatransfers per second—double PCIe 5.0 and four times PCIe 4.0.

Apple typically highlights bleeding-edge technologies at product launches, but this appears to be an error rather than intentional concealment. The M5 Ultra Mac Studio likely uses PCIe 5.0, consistent with other recent Apple silicon devices.
