OpenGL Performance & Performance-Per-Watt For NVIDIA GPUs From The Past 10 Years
While a synthetic benchmark, GpuTest is very demanding on the hardware so I figured it'd be a fun run. From worst to best is a 117x difference in performance for this test that's known to overheat some GPUs.
The performance-per-Watt of Furmark has a 35x difference from worst to best for power efficiency.
While OpenArena becomes CPU bound for modern graphics hardware as it's an old open-source game powered by the ioquake3 engine, it's demanding for the older NVIDIA GeForce GPUs. Here we from the 8500GT to GTX 950 is a 38x difference for these mid-range brothers born a decade apart. From the GeForce 8800GT to GTX 980 is a 56x difference in performance.
OpenArena also allows us to have a look at the total frame time.
