Apple removed a PCIe 6.0 claim from its Mac Studio press release shortly after publishing it, confirming the machine instead uses PCIe 5.0 architecture, the same standard found in the M5 Max MacBook Pro models announced alongside it.
As spotted by French blog MacGeneration, the initial announcement stated the Mac Studio had “next-generation SSD architecture built on PCIe Gen 6.” The edited version now mentions only a “next-generation SSD architecture” delivering up to twice as fast storage speeds versus the previous generation, without specifying the PCIe standard.
PCIe 5.0 Confirmed Across M5 Mac Lineup
The 14-inch and 16-inch MacBook Pro with the same M5 Max chip both ship with PCIe 5.0 SSDs and carry identical “up to twice as fast” storage speed marketing. This parallel spec and messaging across both product lines strongly indicates the Mac Studio uses PCIe 5.0, not 6.0. Apple has not responded to requests for comment, but the consistency between the MacBook Pro and Mac Studio announcements makes the correction plain. No consumer PC on the market currently features PCIe 6.0 storage; PCIe 5.0 remains the fastest standard available in any shipping Mac.
Availability and Pricing
The M5 Max Mac Studio starts at $2,499 (education: $2,299) and arrives starting September 22; pre-orders opened August 25. The M5 Ultra Mac Studio model begins at $5,499 (education: $5,099) and includes an up to 36-core CPU with 12 super cores and 24 performance cores. Mac Studio design remains unchanged for the fifth consecutive year as all upgrades are internal.
Performance gains include up to 4.3x faster AI performance, up to 1.8x faster graphics, and up to 1.3x faster CPU speed versus the previous generation. Wi-Fi 7 and Bluetooth 6 arrive for the first time, facilitated by the same N1 connectivity chip Apple introduced in the iPhone 17 lineup. The PCIe 5.0 spec does not diminish the storage advantage since doubled speed still remains a legitimate upgrade.
