AMD Radeon RX 7900 XTX was supposed to exceed 3.2GHz: Clock targets cut by 700-900MHz [Rumor]

We've heard a lot about AMD's Radeon RX 7900 series of graphics cards. Based on the Navi 31 die, the XTX was supposed to compete with the GeForce RTX 4090 instead of the RTX 4080. Unfortunately, some hardware design flaws prevented the engineering team from achieving the originally set goals. Boost clocks were a big part of this compromise. As noted in the original marketing slide below, RDNA 3 was supposed to be the first graphics architecture to exceed 3 GHz.

However, as we already know from the official specifications, none of the Radeon RX 7900 series cards come close to the 3GHz mark. The 7900 XT tops out at 2.4GHz while the 7900

According to AGF, Navi 31 missed its target clocks by 700-900 MHz, and the Radeon RX 7900 XTX was supposed to underperform the $1499 GeForce RTX 4090 (at least in rasterized gaming workloads). Unfortunately, it targets the RTX 4080 in rasterization and the RTX 4070/4070 Ti in ray-tracing for $500 less.

There was a rumor the other day that the Navi 31 (the die that powers the RX 7900 series) would require a rework to fix all the hardware bugs. This means that AMD will have to review the design of the integrated circuit, which amounts to planning a refresh. RDNA 3+ is supposed to correct all the design flaws of the Navi 31 (in 2023?).
