An RTX 5080 faster than the RTX 4090 in ray tracing?


This time, we’re going to talk about the potential future RTX 5080, which seems to be the target of new rumors. According to some, we could be looking at the biggest generation-to-generation performance boost we’ve ever seen!

RTX 5080 at least as powerful as RTX 4090!

When it comes to rumors, there’s plenty to go around. If we’re to believe what’s being said on the web, the card will be equipped with a GB203 GPU. This would offer the same features as a GB202, but halved. If the future RTX 5090 benefits from 192 SMs and a 512-bit memory bus with GDDR7 memory, we can expect a 256-bit GDDR7 card with 96 active SMs. If the SM composition remains unchanged, we’d have a card with 12,288 cuda cores.

In itself, achieving the performance of the RTX 4090 would not be impossible for NVIDIA. As we’ve seen with this generation, the RTX 4080 (not Super), when it was launched, was ahead of the RTX 3090 Ti with a GPU offering less cuda core and lower memory capacity, and the same goes for memory bandwidth (1008 GB/s vs. 716.8 GB/s). Here, the architectural gains have come into play.

Furthermore, according to @XpeaGPU, we can expect the biggest performance gain from generation to generation. He points out that Blackwell was originally designed to compete with a 3nm RDNA4 GPU in MCM… Which has since been cancelled as AMD wants to focus on the mid-range sector… 🙄

In short, we’ll just have to wait until the end of the year, early 2025 to see what happens.
