Idk if they actually produced the full 500 units. But they likely did. All I know was that months ago, I was told by someone in the know it was to be a 500 unit run. With the way the 3090 Ti launch has gone, and the market has cratered I think that was a good decision by EVGA. Too many more and I'm not sure they would have sold out. Took a few days as is.
Also the bins on all these cards seem pretty good. I haven't seen a single person not be able to maintain about 2160 MHz or more on Port Royal. Outside of the cherry picked launch chips for AIBs by Nvidia the rest of the 3090 Ti silicon (like the other GA102 cards) is really really weak. Seen cards that won't even sustain 2130 MHz. So anyone who got a 3090 Ti KP has a comparatively strong piece of silicon.
