The M6 chip includes a 12-core GPU, adding two more cores than its immediate predecessors, and features faster unified memory with up to 160GB per second of bandwidth

1

. According to Apple, the M6 Mac Mini offers nearly a 30 percent increase in peak GPU compute for AI performance compared to the M5, which improves the speed of prompt processing when using on-device large language models

2

. The Mac Mini with M6 chip starts at $899 with 16GB of memory, representing a $200 price increase from previous base models

Apple's Ultra chips have traditionally connected two Max dies using UltraFusion technology across a high-speed interconnect. The M5 Ultra increases inter-die bandwidth to over 4.4TB per second, allowing the four dies to function as a single CPU

3

. The Mac Studio with M5 Max starts at $2,499, while M5 Ultra configurations start at $5,499

Local AI inference drives Mac Mini and Mac Studio popularity

The Mac Mini and Mac Studio have gained traction for local AI workloads and software development, capitalizing on the advantages of their unified memory architecture and the fast CPUs and GPUs on their AI-ready chips

1

. The devices' popularity for production inference accelerated after macOS 26.2 shipped in December, which enabled "low-latency communication between Thunderbolt 5 hosts for use cases including distributed AI inference using MLX," according to Apple's release notes

1

. Thunderbolt 5 provides very fast wired data connection, and MLX is an open source array framework designed to help machine learning workflows take full advantage of the M-series chips' unified memory

Both hobbyists and professional developers have been daisy-chaining Mac Mini or Mac Studio devices to run inference on local large language models that are much bigger than anything that could run on a single mass-market device, providing an alternative to specialized hardware featuring Nvidia GPUs

1

. In a briefing on the Mac Studio, Apple discussed the ability to connect multiple Mac Studios together over Thunderbolt 5 to run frontier-level large language models with over a trillion parameters locally, allowing the four systems to share memory

3

. The Mac Minis have grown popular over the past year among tech enthusiasts for running local AI agents such as OpenClaw and Hermes, with people selling Mac Minis at marked-up prices on platforms like eBay earlier this year due to rising demand

On-device AI processing targets developers and AI workloads

Apple emphasized on-device AI processing capabilities as developers increasingly incorporate AI coding agents into their workflows, thanks to powerful frontier large language models and sophisticated harnesses like Claude Code or Codex

1

. However, the cost of running cloud models is steep, and many developers are questioning whether it will remain practical. Open-weight models that can be run locally, like some of the latest Qwen and DeepSeek models, can accomplish many of the same tasks without charging for tokens, as they're smaller and driven by the user's own local energy and compute

1

.

"With these frameworks and new chips, developers can run and fine-tune large AI models locally on their Mac," Apple wrote in a press release. "Apple's developer tools and frameworks automatically optimize performance across the CPU, GPU, and Neural Engine, and give developers the ability to use Apple Foundation Models, App Intents to tap into Apple Intelligence features, or their own proprietary AI models to build and run powerful AI workloads entirely on device"

2

. The M6 Mac Mini features a dual 16-core Neural Engine, which doubles the peak AI performance

3

. Both devices feature Apple's N1 chip, which supports Wi-Fi 7 and Bluetooth 6

1

5

. Apple claims the storage is up to twice as fast, at 15GB/s

1

. The Mac Mini ships with 2.5Gb Ethernet as standard, with the option to upgrade to 10Gb

1

.

The M5 Ultra chip supports up to six Thunderbolt 5 ports with transfer speeds up to 120Gb/s of bandwidth, which can drive up to eight external displays, or four Studio Display XDR displays at 5K resolution and 120Hz refresh

5

. Preorders for both Mac Mini and Mac Studio start on August 25, with shipping beginning on September 22, though the 512GB memory configuration for the M5 Max won't ship until late October
