AMD has allegedly scrapped its RDNA 3 refresh, which was set to land between mid to late 2023. This architectural revision was going to fix the bugs plaguing the Radeon RX 7900 XTX/7900 XT (Navi 31) and deliver the originally promised performance targets. Now, it looks like we’ll be getting two more RDNA 3 dies, namely, Navi 32 and Navi 33, and that will be it for the 3rd Generation RDNA architecture.
It’s unclear whether AMD will launch overclocked variants of the RX 7700 XT, 7800 XT, and RX 7900 XTX/XT later this cycle. Either way, it won’t make much difference because these GPUs see little to no gains from overclocking.
At the architectural reveal, AMD promised SKUs with stock boost clocks exceeding 3GHz and performance-per-watt improvement of 50% or more. Unfortunately, neither of these promises was met. The Radeon RX 7900 XT and 7900 XTX draw substantially more power than their RTX counterparts despite falling short in raster and ray-tracing performance.
Said N31 bugged underperform mess 🤷♀️
N33 share similar hardware bugs N31.
Bugs found late to fix.
N32 & Phoenix mostly fix.
RDNA3+ true full fix.
All RDNA3 refresh cancel.
All RDNA3 SKU miss perform & efficient target.
RDNA3 bad all platform.
Jensen win.

The Radeon RX 7900 series GPUs barely have any overclocking headroom. Even those that hit the 3GHz mark see single-digit, inconsequential performance gains. Earlier, it was reported that all the RDNA 3 designs, including Navi 31 and 33, suffered from “un-fixable” flaws that would only be addressed by a refresh later this year.
Unfortunately, the said refresh has been canceled as it failed to meet the set performance and efficiency targets. In short, the Radeon RX 7900 XTX will be the fastest Radeon graphics card for at least the next two years or so.
