80 gigabits bi-directional. Pretty good. Finally arriving after years. Remember Thunderbolt 3 to Thunderbolt 4 didn't bring any speed increase, both were 40Gbps, and we've been stuck with that since 2015. Also, Thunderbolt 5 increases external device data bandwidth from 32Gbps to 64Gbps. We should see a full-blown eGPU (external graphics card) revival then? Ai accelerators etc?
I love really simple stuff that has big practical benefits...bitcoin.
