According to KeplerL2, who is a known source with a good reputation, RDNA 5 is running at between 3.1 GHz and 3.4 GHz in AMD‘s internal test units. Those GPUs would be engineering samples, so there may be room to improve performance in the final units that reach the market.
The operating speed affects the total power that a GPU is able to achieve. If AMD manages to maintain 3.4 GHz in turbo mode with the most powerful GPU in the RDNA 5 series, it could reach unexpected levels of power. Rumors say that it will have 12,288 shaders, which would give us a power of 167.11 TFLOPs in FP32 with dual-issue shaders, and 83.55 TFLOPs in FP32 without dual issue.
AMD RDNA 5 Flagship Rumored With 12,288 Shaders, 32GB GDDR7 and Up to 3.4 GHz
The top-of-the-range RDNA 5 model will use 24 GB or 32 GB of GDDR7 memory, according to other previous rumors. Below this, at least two other models will arrive to cover the upper-mid-range and high-end markets.
We have seen rumors of a version with 5,120 shaders and a 384-bit bus accompanied by up to 24 GB of graphics memory, and another version with 3,072 shaders that would have a 128-bit or 256-bit bus and up to 16 GB of graphics memory.
With the DRAM crisis, AMD may adjust the graphics memory configurations of its next generation, although it is also possible that by the time this new generation launches, prices will have improved and it will not be necessary to reduce the amount of VRAM. No launch date has been confirmed, but rumors say that AMD will launch RDNA 5 between late 2027 and early 2028. This represents a delay compared with the dates originally expected, and the DRAM crisis would be responsible for the delay.
