Yes but i don't agree with this way of looking at it, its slow because of the memory, IE "Bottleneck"
Memory performance isn't the be all and end all of everything related to a CPU's gaming performance, if you put a faster core in there it isn't going to be bottlenecked by the system ram.
Memory performance is a part of what makes up a CPU's performance, its not its limiting factor. in the same way a CPU running 5Ghz and not 6Ghz does not make it the problem, if you can get it to run a 6Ghz your not fixing it, you're enhancing it.
The 13 Gen CPU's here running with 6400MT/s are (More enhanced) than the Ryzen chips running at 6000MT/s, one is more overclocked than the other, they are not apples to apples and wierdly everyone did that, if they have the Intel CPU running at 5600MT/s they had the AMD one running at 5200MT/s.
Its a worrying trend that IMO should be called out more. This was clearly a "Request?" from Intel, and they agreed to it...
