Refurbished Apple Mac Studio 13,1/M1 (20-CPU 64-GPU)/64GB RAM/1TB SSD/A (Early 2022)

Apple Mac Studio M1 Ultra 2022Slotted between the diminutive, inexpensive Mac mini and the massive, expandable Mac Pro, the Mac Studio represents Apple's first foray into a mid-sized desktop system since the demise of the underappreciated Power Mac G4 Cube more than two decades earlier.

This specific configure-to-order high-end model -- the Mac Studio "M1 Ultra" 20-Core CPU/64-Core GPU -- features a 3.2 GHz Apple M1 Ultra processor -- essentially two M1 Max processors interconnected with "UltraFusion" technology -- with 20 cores (16 performance cores and 4 efficiency cores), a 64-core GPU, a 32-core Neural Engine, and a "Media Engine" that provides hardware acceleration for video encoding and decoding. Other custom configurations also are available, but if otherwise configured as the default, it is equipped with 64 GB of onboard RAM and a 1 TB SSD that Apple reports is "not user accessible" (but that actually is removable).

Connectivity includes two Thunderbolt 4 ports and an SDXC (UHS-II) card slot on the front and four Thunderbolt 4 ports, two USB-A ports, an HDMI port, a 10-Gigabit Ethernet port, and a 3.5 mm headphone jack on the back. It has 802.11ax (Wi-Fi 6), too.
