Typical speeds: 100-600 megabits down, much less up.
The new "2 gig peak" chips from Huawei and Qualcomm deliver about the same speed with a similar number of antennas and the same spectrum. You can't get much more speed without breaking the Laws of Physics, whether you call it 4G or 5G.
The real 5G uses perhaps ten times as much spectrum for practical speeds over a gigabit. You can only find 800 MHz free at millimeter wave ranges, mostly 26-30 GHz. I and most others consider Massive MIMO, 64-256 antennas, also 5G.
Early in 2017, the marketing people started to call 3.5 GHz "4G" TDD LTE "5G" even though the speed was almost the same. The result is what Dan Jones calls Faux 5G and I call Fake 5G.
The software tweak (NR New Radio) did little for the speed although NR offers other features. The marketing people love the name 5G and stuck it on everything.
Don't believe the hype.
