No, it doesn't even exist yet.
The specs seem like they will be pretty good though. With the GPU market in shambles at the moment and even with cheap power mining isn't very profitable, I wonder if this next gen of GPU might not be a bad pickup to run for the next couple of years while the market recovers. I could see this next generation sticking around and staying profitable for the next 3-4 years maybe. While that isn't as great as the run the 1080 or Radeon VII had, today that seems like it would be a dream come true. I might have to pick one up to see for myself.
And if there are problems with overheating, you will have to disassemble the expensive video card to install better thermal paste and thermal pads and lose the warranty.
