Getting 25 Gbps Thunderbolt Ethernet on my Mac Studio
Summary
A detailed hardware-oriented test of adding a 25 Gbps Thunderbolt Ethernet NIC to a Mac Studio, including cost considerations, thermal challenges, cooling modifications, and measured throughput. The results show ~20–25 Gbps sustained bandwidth due to Thunderbolt 3 limitations, with real-world copy speeds around 1.0–1.4 GB/s, and a conclusion that the upgrade offers incremental gains depending on workload.
