Nvidia will sell everything no matter what so AMD leaving room for a surprise on oct 28th will not impact Nvidia sales.
Yes, and this same argument was made with the Vega 56 and 64 teases, RX480, etc. "Obviously, that isn't the FASTEST cards, because that isn't what this week's hype suggested!"
Look, that card that they showed today looked pretty damn good and we still don't know RAM, power, cost, and it probably still isn't final...but I imagine it is pretty close to what it will be.
I'm just going to go with what we actually know in recent years of how AMD actually teased what they had, the community insisted endlessly that there was some as-yet-unrevealed killer piece of hardware that they are just waiting to reveal in some dramatic fashion--lol, why even expect drama like this? It's just a piece of hardware, ffs--only for those to never ever materialize.
The Radeon VII wasn't even in their gameplan except for some limited number of harvested dies that they used as a "proof of 7nm" and early test for efficiency. It certainly wasn't ever planned to be a consumer card, if it was ever planned to be a product, but Nvidia, IIRC, created a little space between the 1080 and 1080ti, that, even with not-very game-friendly drivers, the Radeon VII fit somewhat decently.
