Intel's latest Thunderbolt standard delivers 80-120 Gbps for professional workflows.
## The Numbers
- **80 Gbps bidirectional** (2x Thunderbolt 4)
- **120 Gbps asymmetric** (Bandwidth Boost for displays)
- **64 Gbps PCIe tunneling** (vs 32 Gbps on TB4)
## What This Enables
- **Three 4K@144Hz displays** from a single port
- **8K@60Hz** with full HDR and wide color
- **eGPUs at near-native performance** with PCIe Gen 4 x4
- **NVMe storage arrays** exceeding 6 GB/s
## First Devices
Apple's Mac Studio M4 Max (2024) debuted Thunderbolt 5. Intel's Arrow Lake and Lunar Lake CPUs include TB5 controllers. CalDigit and OWC have announced TB5 docks.
## Cables
Thunderbolt 5 passive cables support 80 Gbps up to 1m. Active cables extend this to 2m. For longer runs, optical cables will be available in 2025.
