DDR5 offers higher speeds but may introduce more latency compared to older standards.
DDR5 offers higher speeds but may introduce more latency compared to older standards.
If the initial latency remains unchanged, choosing lower latency is better. Between DDR5-6400 CL32 and DDR5-5600 CL28, the latter offers higher frequency.
Beyond just the speed and CAS latency, other aspects like memory controller settings and additional considerations matter (a 6400 kit would likely struggle on AMD if you only need XMP support). Overall, when the clock speed is higher and timing matches closely despite the frequency gap, that unit performs better.
