From the research I've done, upload speeds are generally considerably lower than your download speeds. I can give you real world numbers from my own experience with the AC1900. I maintain steady 50+ Mbps download and between 12 and 18 Mbps upload anywhere in my 2400 square foot multi floor home along with the Dead Spot Terminator plugged in on the upper floor. I have found these speeds unmatched by any previous product I've personally used. I hope this helps.
