"AIBs were told easily above 3.2Ghz" with normal OC tweaks (power/voltage) and max frequency in beta BIOS is 3.7GHz"
"AIBs built 4 slots monsters cards that can dissipate up to 600W (Same as RTX 4090) based on prelim OC info given by AMD. But Navi31 cannot reach the target..."
"RX 7900 XTX AIB cards with 3x8-PIN reaches 2.8GHz at 450W. Less than 5% perf uplift by this OC on synthetic benchmark (TSE) For now, cannot go above 2.9GHz, whatever the voltage, whatever the power, whatever the binned die, because of "instabilities".
"Bad news: Navi31 needs a respin to fix the issue preventing to reach the 3GHz target at reasonable power level. Hardware team failed this design. Good news: The problem has been identified and corrected for Navi32"

Onestamente pensavo che i 3ghz fossero presi easy, ai 3.7 non ho mai creduto.
Secondo me è solo un fatto di prima infornata, mi ricorda molto la 7970 del 2012 e ci sta anche, come che sono 5nm lisci e non 4nm come quelli sviluppati ad hoc per Ada, un 10% lo hanno tirato fuori senza dubbio.
PS. le x50 prenderanno i 3ghz.
