Well, so far I'm pleased with the provided numbers. They're not great or mind blowing, but they offer a nice performance increase over AMD's current parts.
We have to remember that Navi is replacing AMD's current mid range cards, the RX 480/580/590s, that competed with Nvidia's GTX 1060. it was never meant to be a high end part. And yet we see the 5700 being compared with the RTX 2070! Even if the end product ends being with 10% of the Nvidia card in real world benchmarks, it will already be a massive improvement over what AMD has now.
And there's also an interesting question: this is the 5700 chip/card, will there be a 5800 part?
By the way, regarding power consumption, there will be two cards that will use 180 and 225W: https://wccftech.com/amd-radeon-rx-5000-navi-gpu-7nm-asrock-two-variants-report/
