I'm not exactly sure how anyone would believe marketing hype where a company says they can do something a LOT harder than what Intel, nVidia and AMD have yet to achieve with just CPUs and GPUs

I see no 10nm CPUs or GPUs in the near future, and Bitcoin mining is a lot more power intensive and thus a lot more difficult to manufacture workable chips.

Yet they're boasting jumping straight to 7nm ... ... ...

There's also google-able reasons (related to power issues) why there are no 10nm CPUs and GPUs yet
