Thunderbolt मानक

सभी Thunderbolt मानक संस्करण स्पीड, सुविधाओं, और संगतता के साथ।

Thunderbolt standards combine PCIe and DisplayPort protocols into a single high-speed interface. Thunderbolt 3 (40 Gbps) unified on USB-C, Thunderbolt 4 tightened minimum requirements (dual 4K displays, 32 Gbps PCIe tunneling), and Thunderbolt 5 (80/120 Gbps) introduced PAM-3 signaling. Intel's decision to contribute Thunderbolt 3 to the USB4 specification accelerated industry-wide adoption of high-bandwidth USB-C connections.

Thunderbolt 1

2/10

Intel's first Thunderbolt using Mini DisplayPort connector. Two bidirectional channels at 10 Gbps each. Debuted on the 2011 MacBook Pro and supported daisy-chaining up to …

Thunderbolt 2

2/10

Aggregated TB1's two 10 Gbps channels into a single 20 Gbps stream for 4K video. Still used Mini DisplayPort. The standard on 2013-2015 Mac Pro …

Thunderbolt 3

6/10

Intel's 40 Gbps interface over USB-C, supporting dual 4K displays, eGPUs, and daisy-chaining up to 6 devices. The basis for USB4.

Thunderbolt 4

7/10

Same 40 Gbps as TB3 but with mandatory certification: guaranteed dual 4K or single 8K, PCIe tunneling, and wake-from-sleep. Higher minimum requirements ensure consistent quality.

Thunderbolt 5

10/10

Intel's latest at 80 Gbps bidirectional (120 Gbps with Bandwidth Boost). Supports triple 4K displays, 8K, and PCIe Gen 4 x4 for desktop-class eGPU performance.
