Just a quick explanation:

Taped out
Refers to the completion of the design of a chip. The next stage is to put it into production. The term comes from the early days when designs were transferred to the fabricator via magnetic tape.

So all the specifications you get from FC about the chip rightnow comes from simulations. There's actually still no physical chip produced so there's still a lot of things that can go wrong or be delayed. It's not until the real chip can be benchmarked that we will know for real. I would advice to be a bit cautious before buying into stocks at the current high prices.
