Review TeamGroup T-Force Vulcan Eco DDR5-6000 C30 2x16GB Review: Eco-Friendly DDR5 Performance

"As often happens, the Vulcan Eco memory kit couldn't keep up with performance on the AMD platform."

What do you mean by that, and why does this "often happen"? And are these not ultimately just measurement variations (as indicated also by the kit taking the top spot in gaming performance on the same system)? Or is AMD more picky and complicated about selecting RAM?
In any case, if you think this is a common phenomenon, it would be worth clearer sentences.
