Both GPUs are powerful and capable of running Isaac Sim and Isaac Lab effectively. However, the choice depends on your specific needs:

  • Choose the RTX 4090 if you prioritize raw performance and need the highest CUDA core count for complex parallel computations.
  • Opt for the RTX 5080 if you want to leverage DLSS 4 for potential performance boosts, prefer better power efficiency, and can benefit from higher memory bandwidth.

Given that both laptops have the same RAM and VRAM, the decision comes down to the GPU’s specific strengths. For Isaac Sim and RL workloads, the RTX 5080’s DLSS 4 support and higher memory bandwidth could give it an edge, especially if NVIDIA optimizes Isaac Sim for the new architecture.

However, as the RTX 5080 is newer, it may encounter some compatibility issues with current software versions. Consider checking for any reported issues in this forum.
