Apple's 2025 Mac Studio with M3 Ultra is the most port-dense Mac shipping, anchored by six Thunderbolt 5 ports rated up to 120Gb/s — two on the front, four on the back. The rear panel adds two USB-A (5Gb/s) ports, a single HDMI 2.1 output, a 10 Gigabit Ethernet jack, and a 3.5 mm headphone jack with high-impedance support. The front-facing SDXC slot is UHS-II for fast offload from cinema-grade cameras.
Compact Apple Silicon desktop with 6× Thunderbolt 5, HDMI 2.1, 10GbE, USB-A, SDXC UHS-II, and 3.5mm.

Notes & Compatibility
Queue title was ‘M4 Ultra, 2025’ — Apple never released an M4 Ultra chip; the 2025 Mac Studio top-spec uses M3 Ultra. M4 Max variant ships with USB-C 10Gb/s (USB 3.2 Gen 2) on the front instead of Thunderbolt 5; the rear panel is identical between M3 Ultra and M4 Max. Thunderbolt 5 ports support up to 120Gb/s asymmetric bandwidth and 96W charging when used as a power source.
