Ram speed/latency and memory compatibility

[MartinKweh]

hi i just want to ask if a 3000 Mhz CL 16 ram is better than a 3200 Mhz CL18 ?

 

also is Team Elite Vulcan TUF 16gb 2x8 Memory 3000mhz Ddr4 CL16-18-18-38 compatible with ryzen 3000?

At 3000 MHz a latency of 16 clock cycles translates to about 10.66 nanoseconds.

 

At 3200 MHz a latency of 18 clock cycles translates to 11.25 ns.

 

So slightly increased latency (+5.5%) for mildly increased transfer speed (+6%)

In gaming and some work loads(Autocad, Dialux, skectchup, and programs of the same nature plus coding) what does that translate to?

anything that is better leads to better perfomance overall

True, but e.g. some apps are more latency sensitive and others profit from additional bandwidth.

 

It's hard to say which is which, without benchmarks. The differences between the values above are fairly minimal though, so shouldn't matter too much.
