Users need to wait for 10 weeks to receive Apple Mac Studio
At the Spring Conference in March this year, Apple launched a new Mac Studio compact workstation with the highest-end M1 Ultra in the M1 series chips. The Mac Studio has equipped with four Thunderbolt 4 ports, two USB-A ports, a full-size HDMI port, a 10Gb Ethernet port, and a 3.5mm professional-grade HD audio interface. Two USB-C ports (two Thunderbolt 4 for the M1 Ultra version) are also added to the front of the fuselage, as well as a full-size UHS-II level SDXC card slot.

According to MacRumors, although Apple has released the Mac Studio for nearly half a year, it still faces serious delays in shipping, and it takes up to 10 weeks to choose the top configuration. Apple did not explain the specific reasons. If you choose the M1 Max with less performance and functions, you also need to wait 1 to 2 weeks.
The 10-week wait for the top-of-the-line version likely reflects the high demand for Mac Studio. Compared with many similarly positioned products, Mac Studio has better portability and complete port configuration, which is convenient for users to connect various peripheral devices, including high-resolution monitors or multiple monitors, to improve work efficiency.
M1 Ultra consists of 114 billion transistors. The two M1 Max chips are interconnected through an innovative packaging architecture called UltraFusion which can be configured with 128GB of high bandwidth, low-latency unified memory, plus up to 20-core CPU (16 performance cores + 4 energy efficiency cores), 64-core GPU, and 32-core NPU. Like the M1 Max chip, each performance core has 192KB of instruction cache, 128 KB of data cache, and a total of 48MB of L2 cache, and each energy-efficient core has 128KB of instruction cache, 64KB of data cache, and a total of 8MB of L2 cache.
