Thunderbolt 5 vs USB4 v2: 120Gbps Bandwidth, Triple 4K Display Docks & External GPU Enclosures

Triple Bandwidth Boost: From 40Gbps to 120Gbps

For high-end workstations and creative studios in Nairobi, connecting high-speed NVMe storage arrays, dual 4K/144Hz displays, and external audio/video capture devices through a single cable has always pushed Thunderbolt 4's 40Gbps ceiling to the limit. Thunderbolt 5 changes this by providing 80Gbps bidirectional throughput and up to 120Gbps Bandwidth Boost for video-intensive workflows.
