Which memory is better?

DDR4-3000 CAS 15 or DDR4-3200 CAS 16. Same amount of RAM.

DDR4-3000 CAS 15 or DDR4-3200 CAS 16. Same amount of RAM.

In real world performance, they're about the same. Get the cheaper set. For reference, your performance plateaus will be at 2133mhz, 2666mhz, and 3000mhz. Anything in between 2133mhz and 2666mhz, between 2666mhz and 3000mhz, or above 3000mhz won't really show any real world performance difference compared to 2133mhz, 2666mhz, or 3000mhz themselves.

They're the same price, are you sure one isn't better than the other by a tiny bit?

The 3200Mhz performs marginally better than the 3000Mhz, if you look only at numbers. In real world practice and applications, you will not notice a difference at all. If they're the same price, then go for the faster speed (bragging rights). The CL is so close that it doesn't matter.

Ok, thank you.

Not a problem. For reference, there are a couple of videos on Youtube that Linustechtips created on this exact topic for both DDR3 & DDR4. Both generations show very similar results in terms of marginal performance between frequencies in real world application. Most of the difference is hype.

However, in terms of CPU & DRAM combo, Ryzen works better with faster DRAM, especially when overclocking CPU cores. Intel doesn't, at this time, show those same results.
