32GB CL18 vs 16GB CL16: Capacity wins over latency for gaming
Go for 32GB. The capacity bump helps more than the latency difference hurts. In gaming, CL16 vs CL18 at the same frequency is only 1-2% in frame rates—you won’t feel it. But running out of RAM with 16GB causes stuttering and longer load times in modern games. Capacity is the real bottleneck, not latency.
