It goes to hell if you max out upstream. At cell edge it's easy to do. Modem type in use greatly affects how it'll perform real-world. N71 (600mhz) standalone 5G without carrier aggregation tends to be shit as just like Band 12 (700mhz) LTE. It's their low frequency coverage band for 5G and congests since the towers are spaced far apart and it uses less spectrum. Newer phones can aggregate multiple N71 and N41 carriers and get very low latency high performance connections, but it's still location dependent.
