What is Thunderbolt 5?
Intel's latest Thunderbolt standard — up to 120 Gbps bandwidth. Enables high-bandwidth eGPU enclosures, fast NVMe storage, and 8K display output from compact AI machines.
Full Explanation
Thunderbolt 5 doubles the bandwidth of Thunderbolt 4 (40 Gbps → 80 Gbps bidirectional, burstable to 120 Gbps asymmetric). For AI workloads, the key application is high-speed NVMe storage for model libraries — an external Thunderbolt 5 NVMe enclosure can deliver 5+ GB/s sequential read speeds, fast enough to stream model weights without measurable latency. It also enables Thunderbolt eGPU enclosures (though bandwidth limits still apply for GPU-intensive workloads).
Why It Matters for Local AI
Mac Mini M4 Pro users managing large model libraries benefit most from Thunderbolt 5 storage. A 100 GB model library (several Llama 70B quantizations) loads substantially faster from a TB5 NVMe drive versus USB-A storage.
