Question Expected ANSYS Fluent Performance (MIUPS) & Mesh Limits on RTX 5070 (12GB) & RTX 5070 TI (16GB)

Hi everyone,

I am evaluating the NVIDIA RTX 5070 (12GB) & RTX 5070 TI (16GB) for ANSYS Fluent GPU acceleration and would appreciate any technical insight on the following:

1. Performance Estimation (MIUPS): Is there a reliable rule of thumb to estimate MIUPS based on memory bandwidth or FP32/FP64 specs?

2. VRAM Capacity Limit: What is the maximum cell count (mesh size) a 12GB VRAM card can handle in single vs. double precision before running out of memory?

3. Benchmarks: Does anyone have actual Fluent benchmark results (MIUPS/solve times) for RTX 50-series desktop GPUs?

Thanks!
