One of the most reliable leakers of NVIDIA-related rumors, kopite7kimi, published on X.com what would be the main technical specifications of the upcoming top-of-the-range 50 series video cards, based on the new Blackwell architecture. The new RTX 5090 and RTX 5080, which could be announced before the end of the year, both see a significant increase in power consumption compared to their respective previous generation models, with the RTX 5090 expected to consume up to 600 watts of power . It is not clear from the leak whether this is TDP at the video card or GPU level. The card would still use a two-slot heatsink. For the RTX 5080 we would instead be talking about 400 watts. For reference, the RTX 4090 at the card level had a TDP of 450 watts, while the RTX 4080 had 320 watts.

According to rumors, the GeForce RTX 5090 will be equipped with 32 GB of GDDR7 memory with 512-bit bus and GB202-300 GPU with 21760 cores for FP32 instructions, while the RTX 5080 will have specifications practically halved, with 16 GB of GDDR7 memory, bus 256-bit, GB203-400 GPU with 10752 FP32 cores. 16 GB for a card in this range is starting to feel a little tight and what happened when NVIDIA announced the RTX 4080 with 12 GB of VRAM could repeat itself.

However, it is currently unclear when we can expect an announcement of the 50 series of GeForce cards. The current 40 series is now two years old, with the RTX 4090 and RTX 4080 having been announced exactly two years ago now. According to some sources, the new cards could be announced before the end of the year, others point to a launch during the CES in Las Vegas which will be held as usual at the beginning of January.
