| HoloDust said: From that video, Battlefield1 uses 50%, while Witcher 3 uses only 17-18% of INT math (compared to FP). So, using games form that chart, in worst case scenario. 3080 is actually 22.5TFLOPS FP32 card, in best case scenario it's around 27TFLOPS...and of course, theoretically, it's 30TFLOPS FP32 card if no INT is used. I guess that architecture actually makes a lot of sense, cost and effective wise, depending on the balance of FP vs INT math. |
That's not how it works, since the GPU will be bottlenecked by its integer performance during rasterisation, and a number of other factors, even if you tossed infinite floats at the other side of the equation.
This is why Nvidia's own chosen benchmarks won't even double the performance of the 10 TFLOPS RTX 2080. Of course, though, a computing benchmark feeding ideal chunks of data with ideal scheduling might toss up numbers that live up to 30 TFLOPS or relatively close to it.
