It looks like the latest AMD cards are a bit more power hungry than NVidia counterparts. On performance, the Radeon VII seems to be closely aligned to the RTX 2080 (not TI). The RX 5700 XT is around the RTX 2070, and the RX 5700 is above the RTX 2060. Depending on your workload, and if it can leverage the AMD targets, it could be good to great. If you don't actually care about RTX features (and the slow framerates that comes with it), then you're better off with AMD for the price difference, even considering the extra power needs.
