AMD Ryzen RX 7900 Series (Navi 31) Performance May be Bottlenecked by its 355W Power Limit [Rumor]

AMD’s Radeon RX 7900 series will offer solid raster gaming performance with mediocre ray-tracing capabilities. Before the announcement, rumors claimed that Navi 31 suffered from a design flaw that severely limited its peak boost clocks. The said flaw was allegedly fixed with Navi 32 and Navi 33, but the flagship remains affected. Some additional info on this subject has surfaced via the trustworthy sources of KopiteKimi:

According to the well-reputed tipster, the problem may lie with the strict power consumption limit rather than the boost clocks. Of course, power and operating frequencies directly affect one another, but this implies that AMD overestimated the efficiency of its RDNA 3 graphics architecture. Or, more likely, the engineers couldn’t figure it out. But most importantly, this is based on a “may” rather than hard facts.

This rumor is backed by the fact that AIBs are pairing their Radeon RX 7900s with three 8-pin power connectors capable of delivering up to 450W of TBP. As expected from the 300-355W power spec, the reference variants feature only two.

Regardless, Navi 31 has seemingly failed to deliver on all its promises, most notably the fabled 3GHz boost.
