A compact Studio cylinder, ports facing the camera, empty desk. The Standard art desk.

On 25 August 2026 Apple put M5 Max and M5 Ultra in the Mac Studio cylinder. MacRumors, Hartley Charlton, timestamped the file 6:13 a.m. PDT the same Tuesday. Pre-order opened that morning. Machines ship 22 September. The 512 GB unified-memory SKU is late October.

M5 Ultra is Apple’s most powerful chip, MacRumors’s sentence. The story under it is not a model essay. It is the ports, the displays, the SSD, the small cylinder that still sits on a desk, and the three dates on the calendar.

Thunderbolt 5 is the new pipe. MacRumors: up to 120Gb/s of bandwidth. That is the number to write on the back of the cylinder. High-performance peripherals, displays, expansion, external storage: those are the jobs that number is for. Genlock over USB-C is new on this machine. A display and a camera can be locked to the same clock. Wi-Fi 7 and Bluetooth 6 arrive on Mac Studio for the first time, through Apple’s N1 chip. Those two radios were the missing lines on the previous Studio. They are on this one.

Displays: up to eight. MacRumors prints that as a hard ceiling. Eight is a colour-bay number, a scopes-and-client-and-timeline number. It is not a living-room number. The cylinder is still the cylinder. The new fact is how many panels the back of it will drive.

Storage is a PCIe Gen 6 SSD architecture. Apple, via MacRumors, says up to twice as fast as before. Twice is the word. Project load, file copy, the wait before a timeline opens: those are SSD jobs. M5 Max configurations go up to 8 TB of storage, MacRumors’s Max table. The Ultra story in the same file is memory more than disk, but the Gen 6 line applies to the machine.

The chassis is the compact Studio cylinder that has lived on desks since the first of these machines. 25 August did not redesign the object into a tower. It put new silicon in the same small can, and it put new I/O on the same small can. That is the industrial fact. A quiet cylinder, ports on the front and the back, a machine you do not hide under the table.

Calendar. 25 August 2026, pre-order. Tuesday 22 September, ships — to customers and, per MacRumors’s companion note the same morning, to Apple Stores and authorized resellers. Late October, the 512 GB unified-memory configuration. Joe Rossignol, MacRumors, 9:55 a.m. PDT on 25 August: the M5 Ultra with 512 GB of RAM is late October, “with U.S. pricing expected to start well above the $10,000 mark.” That is the dollar on the top SKU. The rest of the sheet is cores, ports, and days.

M5 Ultra, as a spec table, not as a thesis. Up to a 36-core CPU: 12 super cores and 24 performance cores. Up to 1.25x single-threaded and 1.3x multithreaded versus M3 Ultra, the previous Studio’s top chip. GPU up to 80 cores, with a Neural Accelerator in each core. Peak GPU compute: up to 4.5x versus M3 Ultra, more than 6x versus M1 Ultra. Graphics: up to 40 percent faster than M3 Ultra, from latest shader cores, second-generation Dynamic Caching, hardware mesh shading, and third-generation ray tracing. Media Engine: dedicated hardware for H.264 and HEVC, four ProRes encode and decode engines, hardware AV1 decode. Neural Engine: 32 cores, a spec-table line. It is not the subject of this page.

UltraFusion is how the Ultra is built. Two dual-die M5 Max chips, four dies as one processor. Inter-die bandwidth over 4.4TB/s. Connection density more than 6x. MacRumors’s sentences. The cylinder holds that stack. The user does not cable the four dies together. The chip does.

Unified memory on the Ultra: up to 512 GB. Bandwidth: up to 1.2TB/s, a 50 percent step over M3 Ultra. 512 GB is the late-October SKU. 1.2TB/s is the pipe those 512 GB ride. MacRumors also notes Apple’s line that the added memory and bandwidth lets users store large datasets locally. Keep it as a memory fact. The machine is a cylinder with a very wide bus.

Clustering is a port fact, not a research paper. Thunderbolt 5 plus RDMA, remote direct memory access. Four Studios, Apple says via MacRumors, up to 3x inference against a single system. Write it once. The useful object is the 120Gb/s port that makes the cluster possible.

M5 Max is the other SKU in the same cylinder. 18-core CPU: 6 super cores and 12 performance cores. GPU up to 40 cores. Unified memory up to 128 GB, bandwidth up to 614GB/s. Storage up to 8 TB. Apple, via MacRumors: up to 3.9x faster AI than the previous generation. One spec sentence. Then back to the Max as the machine you can actually configure this month: 18 and 40 and 128 and 8 TB, shipping 22 September, pre-order live since 25 August.

Same day, 25 August, Apple also put M6 and M5 Pro in the Mac mini, cut the price of the polishing cloth, and updated Magic Keyboards. That is one sentence. This file stays on the Studio.

Tim Hardwick, MacRumors, 6:45 a.m. PDT 25 August: pre-orders already live on Apple’s online store and in the Apple Store app in the United States and 30 other countries and regions. Most configurations ship Tuesday 22 September, which is also when the new models will be in stores and at authorized resellers. Joe Rossignol’s roundup the same morning listed the mini, the Studio, the cheaper cloth, and the keyboards as the day’s drop. The Studio half of that list is this page.

What 25 August did not do is change the shape of the product. The Mac Studio is still the small aluminium cylinder. What changed is the silicon in it, the speed of the SSD under it, the 120Gb/s Thunderbolt 5 on it, the N1 radios, genlock over USB-C, and the eight-display ceiling. What the calendar did is simpler. Pre-order 25 August. Door 22 September. 512 GB in late October, expected well above $10,000 in the United States.

The wait on the calendar is twenty-eight days from the 25 August pre-order to the 22 September door. Late October is a further month for the 512 GB SKU. 30 August, the day this newspaper is filing, sits five days into that first wait. Hartley Charlton’s 6:13 a.m. PDT piece is still the primary MacRumors file for the cylinder. Hardwick’s 6:45 a.m. PDT companion is still the pre-order geography: United States and 30 other countries and regions, Apple’s online store and the Apple Store app. Rossignol’s 9:55 a.m. PDT note is still the 512 GB caveat and the “well above the $10,000 mark” U.S. line.

Ports first, then silicon. 120Gb/s Thunderbolt 5. Genlock on USB-C. Wi-Fi 7. Bluetooth 6. N1. Eight displays. PCIe Gen 6 SSD, twice as fast. Up to 8 TB on the Max. 512 GB unified memory on the Ultra in late October, 1.2TB/s of bandwidth, 50 percent over M3 Ultra. UltraFusion over 4.4TB/s between dies. A 36-core Ultra and an 18-core Max in the same small can. That is the machine Apple put up for pre-order on 25 August, and that is the machine that ships on 22 September unless you are waiting for 512 GB.

Sunday 30 August is five days after the drop. The pre-order has not been pulled in the MacRumors file this newspaper is using. 22 September has not been moved. Late October is still the 512 GB caveat. Eight displays. 120Gb/s. PCIe Gen 6, twice as fast. Wi-Fi 7. Bluetooth 6. Genlock on USB-C. A 36-core Ultra and an 18-core Max. A cylinder you can still lift onto a desk. The ports and the dates stay on the page. Leave the rest of the day’s mini and cloth on the other page.
