I’ll take a solid reliable 20-50Mbps of LTE on a power-sipping SOC over Qualcomm trying to beat their chests with another space heater of a chip for network applications that just don’t exist yet.
4G was fast too, but couldn't handle lots of concurrent connections, necessitating the need to artificially constrain demand (data caps).
This is also the thing with Wi-Fi, you would unlikely to get ~6Gbps unless you're the sole user, but the improvements allow for faster and lower-latency real-life speeds.
What if Qualcomm told you 12Gbps 5G downloading 5MB uses less energy than 50Mbps LTE?
Getting faster and more efficient 5G is how you can use lower energy per MB transferred. Except most of the time the faster connection the more content the internet wants to push to you.
I was comparing the cellular tech only. i.e not limited by the backbone. Most people compare it with the best iteration of LTE, full spectrum available while on the other than 5G is still on NSA, less spectrum, and RAN not even optimised.
