3 Reasons DDR4 CL14 Beats DDR5 CL28 for Factorio

Lower absolute latency DDR4-3600 CL14 has a true latency of about 7.8 ns, while DDR5-6000 CL28 is roughly 9.3 ns — that’s 20% worse. CL numbers are cycles, not nanoseconds, so DDR4’s tighter timing wins.

Factorio is latency-bound, not bandwidth-bound The game’s simulation loop waits on memory latency, not bandwidth. DDR5’s bandwidth advantage helps rendering or data work, but not Factorio.

Upgrading to DDR5 can hurt performance here Even faster DDR5 (e.g., 6400 CL28 at ~8.75 ns) still trails DDR4. If Factorio is your main game, sticking with DDR4 is the smarter choice.
