DDR5 latency is mostly irrelevant for esports.

Not enough to make a real difference in your minimum FPS.

DDR5 has higher CL numbers — CL30 vs CL16 for a typical kit — but the actual latency in nanoseconds comes out about the same because DDR5 runs at double the frequency. For esports titles like Valorant, CS2, or Overwatch, your 1% lows are almost entirely determined by CPU core speed and cache, not RAM timings. NVIDIA and AMD’s GPU driver overhead matters more than your CL rating.

I’ve seen plenty of benchmarks where DDR4-3600 CL16 and DDR5-6000 CL30 trade blows within 1–3% on minimum FPS. The difference is smaller than the variance between two runs of the same benchmark. If you already own DDR4 and a compatible board, upgrading for esports alone is a waste of money. If you’re building new, just buy DDR5 and don’t think about it.

You have bigger problems if your 1% lows are bad — it
