For this to work with a desktop PC, you would need to connect your display cable to your iGPU instead of your dGPU. The driver should take care of the rest. This might yield lower performance when using dGPU for processing (probably unnoticeable, depending on circumstances).
That’s like saying clock rate and core count are fake terms. Sure, by themselves they might not mean much, but they’re part of a system that directly benefits from them being high.
The issue with teraflops metric is that it is inversely proportional (almost linearly) to the bit-length of the data, meaning that teraflops@8-bit is about 2x(teraflops@16-bit). So giving teraflops without specifying the bit-length it comes from is almost useless. Although you could make the argument that 8-bit is too low for modern games and 64-bit is too high of a performance trade off for accuracy gain, so you can assume the teraflops from a gaming company are based on 16-bit/32-bit performance.
