Deversification will only get deeper as time goes on, I'm afraid, my friend.
- There will be people who want Zen 3 based GPU tests, because for their scenario it makes the most sense
- There will be people who want Intel based GPU tests, since globally it is still very common
- There will be people who want tests with slower and more common memory speeds, and those who want with high speeds and tight timings
- There will be people who want CPU tests with an RTX 3080 because it is the most advanced NVIDIA GPU the common can afford, but others who want an RX 6800 XT one because it represents a fair alternative
- There will be those who want GPU tests on both Intel and AMD systems, since RDNA 2's SAM feature is AMD exclusive, but you can't exclude most users who don't have the option to use SAM since they have already purchased older hardware
- RTX ON? RTX OFF? Smart Cache OFF? Smart cache ON? What about 8 core vs 10 cores vs 12 cores? And Memory types and configuration? why not 4 DIMMS? why not 2 DIMMS?
- What about overclocking? And what about manual memory tuning? will you be tuning each system to its own capabilities? And what about cooler use? Air, WC, or maybe just stock?
With how many possible branches to base a testing platform on, you just can't satisfy everyone. Makes sense.
I'd advise the little I can here, and say, go with the gut feeling of what can serve the common viewer the most benefit. At times, Its ok to serve a piece of information knowing not everyone can benefit from it, but at least a sizeable amount of readers can.
Extrapolate, my friends... extrapolate.
