It's a common theme in almost every area. Take high-end stereo equipment for example. You can spend 10x the money for 5% improvement. People buy high-end usually because they can. To some people, none of the highest-performing CPUs are worth the price. To others, price does not matter. For those people, the fastest gaming CPU is not actually the 5800X3D.Thanks for the link. Pretty amazing what happens with the whole story rather than cherry-picked test results.
Looks like the conclusion is absolutely NOT worth the price-premium of high end DDR5.
