It's far more invasive than just "console optimizations" ...
Using VXGI over ray tracing affects rendering on a "fundamental" level. It won't matter how many samples you spend for VXGI compared to ray tracing when it won't "converge" to the correct result ...
As far as the "real thing" is concerned, I prefer to define the deviation of reference vs approximate results as the mean square error ... 
(all of the recent DXR/RTX demos also using path tracing with denoising)
