Sure someone will correct me if I am wrong....
Product page is fine I believe.
1582 is the base clock. The boost clock is 1695 which it will hit no issues on Boost. When you pop one of these bad boys in they will most likly (like all other 1080ti s cards) boost to 19xx anyway, which is beyond the 1695 mentioned.
The 2025 is what you are guaranteed to get at least with overclocking it yourself past the automatic boost. I don't think any other card has that guarantee from what I have seen so far from the manufacturer.
However, some 1080ti can do that (not all) and that is the silicon lottery you might have seen people talking about around the internet.
