Building a Mac Studio Cluster for local LLM inference, specifically to handle massive models like Kimi K3, requires connecting multiple top-tier machines using high-speed distributed frameworks (like Exo with RDMA or specialized llama.cpp clusters).

To reach the 1.5 TB to 2 TB unified memory pool required for Kimi K3 at MXFP4, you would need to cluster 4 to 8 top-spec Mac Studios configured with maxed-out unified memory.

Here is the quick breakdown of the estimated hardware costs and actual power footprints.

1. Hardware Cost Estimate
To hit the necessary memory threshold, you need to purchase the high-end variants of the Mac Studio (such as the M2/M3/M4 Ultra tiers featuring maximum unified memory configurations).

The Hardware Setup: * 4× Mac Studios with 512GB Unified Memory each (Total: 2TB VRAM), OR

8× Mac Studios with 256GB Unified Memory each (Total: 2TB VRAM).

Per-Unit Cost: A maxed-out Ultra-series Mac Studio with maximum memory allocations ranges from $7,000 to $10,000 depending on the specific chip generation and SSD storage choices.

Networking Infrastructure: High-speed Thunderbolt 4 bridges or 10GbE switches to mitigate cross-node communication slowdowns (~$1,000 - $2,000).

Total Estimated Capital Expenditure (CapEx): $30,000 to $65,000

2. Power Consumption
The massive advantage of an Apple Silicon cluster over traditional Nvidia enterprise rigs (like H200s or B200s) is its extreme energy efficiency. You do not need dedicated datacenter cooling or specialized 240V industrial circuits.

Idle Power Draw: ~15W to 20W per Mac Studio. A 4-node cluster idles at just 60W – 80W (roughly the power of a standard incandescent light bulb).

Peak Inference Power Draw: Under heavy token generation load, each Ultra-tier Mac Studio draws roughly 150W to 250W maximum.

For a 4-node cluster, full-tilt power usage sits between 600W and 1,000W.

For an 8-node cluster, full-tilt power usage sits between 1,200W and 2,000W.

Electrical Needs: A peak draw of 1,000W to 2,000W means the entire cluster can run safely 

3. Speed

A plausible range for a large distributed Mac cluster might look like this:
