Apple Mac Studio with M4 Max or M3 Ultra Chip
Compact desktop workstation — M4 Max or M3 Ultra silicon
Apple's desk-side compact workstation. The mid-2025 refresh kept the Ultra tier on M3 Ultra (Apple's typical pattern — Ultra silicon trails the Max by one generation since it requires two stitched dies). M4 Max for serious creative / dev pros; M3 Ultra for ML researchers and video pros needing the highest unified memory and GPU core count Apple ships.
- M4 Max (up to 16C CPU, 40C GPU) or M3 Ultra (up to 32C CPU, 80C GPU)
- Up to 512 GB unified memory (M3 Ultra)
- Up to 16 TB SSD
- 6× Thunderbolt 5 (M3 Ultra) / 4× Thunderbolt 5 (M4 Max)
- 10 GbE standard
- HDMI 2.1, SDXC card slot, 2× USB-C front
- Drives up to 8 external displays (M3 Ultra)
- 19.7 cm square chassis

Key Features
Everything you need in one device
⚡
6× Thunderbolt 5
M3 Ultra configuration ships six TB5 ports — supports external NVMe arrays, GPU enclosures, 8K monitor chains, and complex audio/video I/O simultaneously.
🌐
10 GbE standard
10 Gigabit Ethernet on every configuration. For NAS-backed creative pipelines, significantly faster than the Mac mini's optional 10 GbE.
🎬
8 external displays (Ultra)
M3 Ultra drives up to eight external Pro Display XDRs simultaneously — for multi-monitor editing, broadcast, finance, and reference-grade post-production.
🧮
Up to 16 TB SSD
Configurable storage up to 16 TB at order time. Critical for video editing pipelines needing active scratch on internal storage.
🔌
Front + rear I/O
2× USB-C front (USB 3 on Max; TB5 on Ultra), SDXC front, plus rear TB5 + USB-A + HDMI + 10 GbE + 3.5 mm combo.
🎨
Reference workflow ready
Pairs with Apple Pro Display XDR for HDR film / TV post-production. Calibrated reference modes for film, broadcast, photography, print.
About the Mac Studio (M4 Max / M3 Ultra)
The Mac Studio with M4 Max / M3 Ultra is Apple's desk-side compact workstation. It targets users for whom the MacBook Pro 16" is the right portable but inadequate as a primary desk machine — ML researchers, video post-production studios, broadcast / streaming professionals, 3D artists, and engineers who need the highest sustained compute Apple ships in a fixed-desk form factor.
The differentiator versus the Mac mini is silicon ceiling and I/O. M4 Max in the Mac Studio runs at higher sustained performance than the same M4 Max in the MacBook Pro 16" (thermal headroom in the desk chassis is much better). M3 Ultra is Mac Studio exclusive — two M3 Max dies stitched via UltraFusion interconnect, doubling CPU cores (32), GPU cores (80), and unified memory ceiling (512 GB at 819 GB/s bandwidth). Note: Ultra silicon historically trails Max by one generation (M2 Max + M1 Ultra in the first Studio, M4 Max + M3 Ultra in this generation) — Apple's pattern reflects the engineering cost of die-stitching.
I/O is where the Mac Studio earns its workstation classification: 6× Thunderbolt 5 ports on Ultra (4× on Max), 10 GbE standard (not optional), HDMI 2.1, SDXC front, 2× USB-C front, USB-A rear. Drives up to eight external displays on Ultra — enough for genuine multi-reference-monitor video / broadcast workflows. The 19.7 cm chassis is slightly larger than the Mac mini but still compact enough to live on a desk corner.
For UK business buyers, Mac Studio is the right pick for fixed-desk creative / engineering / ML roles where a MacBook Pro 16" isn't enough — particularly for shared edit suites, AI research workstations, and reference-monitor video pipelines. Servnet quotes alongside Apple Pro Display XDR, Studio Display, and full AppleCare+ for Business coverage.
