For our manual overclocking tests, we use AMD's built-in tuning tool. Our best results are as below.

Overclocking the RX 9070 XT is very similar to the RX 7000 series, in the sense that the overclocking bit itself doesn't really matter, but it all depends on how far you can lower voltage. For the Nitro+, I maximised the power limit at +10%, added 450MHz to the GPU clock, set the memory clock to a maximum of 2750MHz, and managed to set a -120mV offset.

This resulted in performance gains of 6-8% for the Nitro+, which is fine, though also nothing particularly special. Of course, your mileage may vary depending on the silicon lottery and other factors.

We did see power draw rise a good amount however, hitting just under 382W when overclocked – a 10% increase over stock.
