The rumored specifications for Nvidia’s GeForce RTX 5090 and RTX 5080 GPUs have surfaced recently, suggesting major upgrades in Nvidia’s flagship product line. According to recent leaks from tech leakster kopite7kimi, these GPUs are expected to be a massive improvement over the current generation.
The Nvidia GeForce RTX 5090 is said to have the new Blackwell architecture with 21760 CUDA cores that are running on the GB202-300-A1 chip. This is a huge jump compared to the RTX 4090 which has only 16384 CUDA cores. This could be due to the 32GB of GDDR7 VRAM and 512-bit interface on the RTX 5090 which might be present, a memory bandwidth of 1.79TB/s a slight increase from the previous model.

The power consumption is another feature that is not the same between the RTX 5090 and the RTX 4090. It is also believed that the new card will require 600 watts of power, which is quite a jump from the 450 watts for the RTX 4090. This power increase could be for the entire GPU board or the chip itself, with the remaining details to be announced. However, it suggests a higher power consumption boost for Nvidia’s next leading graphics card.

Apart from the RTX 5090, the RTX 5080 is also expected to have performance improvements and higher power consumption. The rumored specifications point to the RTX 5080 coming with 16GB of GDDR7 memory along with a 256-bit memory bus. Additionally, the CUDA core count will go up to 10,752, and it may consume up to 400 watts, an increase from the 320 watts in RTX 4080.

Rumors about the specifications suggest that Nvidia’s RTX 50-series is a huge improvement over the RTX 30-series. These two cards are built into the GDDR7 memory hierarchy, and they certainly will have a significant impact on performance.
Nvidia is expected to launch its new Blackwell GPUs in CES 2025, including the RTX 5090 and RTX 5080. Although the exact frequencies and price have not been disclosed, the preliminary reports indicate that the model may provide up to 70% more performance than its predecessor.
In addition, AMD may also show its next-gen RDNA 4 GPUs at the event, but they will possibly have a lineup of mid-range and mainstream products. Intel is expected to come into the market with its Arc Battlemage series in late 2024, thus creating stiff competition for the next generation of GPUs in 2025.
