Nothing new folks. 23 years ago I bought a RIVA TNT video card (https://en.wikipedia.org/wiki/RIVA_TNT) where early models (and, conveniently, the ones sent to reviewers) were clocked at 110Mhz. They silently clocked them down to 90Mhz after a month or so before I got mine.

“The TNT shipped later than originally planned, ran quite hot, and was clocked lower than Nvidia had planned at 90 MHz instead of 110 MHz. Originally planned specifications should have placed the card ahead of Voodoo2 in theoretical performance for Direct3D applications, but at 90 MHz it did not quite match the Voodoo2”

I’ve been a bitter man ever since…
