NVIDIA GeForce RTX 4090 is the flagship graphics card of the previous generation, while RTX 5080 is the sub-flagship of the current one. Let's compare the performance of these two GPUs and determine which is better to choose in 2025.
Gaming Performance
Regardless of whether ray tracing and DLSS anti-aliasing are enabled, the NVIDIA GeForce RTX 4090 is 5-15% more powerful than the RTX 5080 in games. The new model has fewer transistors, CUDA cores, texture units, shader units, and rasterization units.
However, the NVIDIA GeForce RTX 5080 supports Multi Frame Generation technology, which creates multiple intermediate frames between two real ones. With this algorithm enabled, the new graphics card delivers an average of 70% higher FPS than the RTX 4090 with standard frame generation.
The key feature of the RTX 5000 series is its next-generation tensor cores, which power AI algorithms. Their performance has significantly increased, enabling Multi Frame Generation. The previous generation's tensor cores are too weak, so RTX 4000 GPUs do not support this technology.
Performance in Work Programs and Applications
Due to a higher number of transistors, CUDA cores, and VRAM, the RTX 4090 outperforms the new model in almost all professional tasks. The RTX 5080 surpasses the previous flagship only in a few cases:
- Working with 4-bit numbers in AI operations;
- Converting and handling multiple video streams simultaneously;
- Processing video files recorded with 10-bit color depth and 4:2:2 chroma subsampling.
This was achieved by incorporating next-gen tensor cores and adding a second hardware decoder to the GPU architecture.
Power Consumption
The new model consumes 360W, which is 90W less than the RTX 4090. It generates less heat and requires less energy, making it slightly more compact and cooler. Additionally, it does not require a high-end 1000W power supply—most systems will work fine with a 750W model.
Conclusion
Comparing both GPUs, the results are as follows:
- The RTX 5080 outperforms the RTX 4090 in gaming only when Multi Frame Generation is enabled. In all other cases, the new model lags behind by 5-15%.
- The RTX 5080 surpasses the RTX 4090 in some professional tasks, mainly in machine learning and video processing.
- The RTX 5080 consumes less power and generates less heat than the RTX 4090, with a power consumption difference of 90W.
