I’m not sure if latency is much of a thing with DDR5 compared to earlier gens, but 9600 MHz at CL44 is comparable in latency as 6400 MHz at CL30. The former with a latency of 9.167 and the latter having a latency of 9.375. So a slight imrovement to what I can see is one of the better choices currently available, so they seem like something worth buying if the price is reasonable.

For AMD the frequency matters more (there are sweet spots for their CPUs), but these do not even support AMD Expo according to the article, so currently these are only worth using with Intel anyways.
