Understanding RAM speed and its impact on performance
Understanding RAM speed and its impact on performance
I've been trying to find a benchmark that compares RAM speeds and latencies on the same hardware. Previously, I used four DDR3 sticks at 1600MHz, but their latencies varied (9-9-9-24 to 10-10-10-27). They only worked properly at 1333MHz. How much did this affect my performance? What real percentage impact does it have in everyday use? Some newer boards support DDR4 up to 3200, so if I switch to a 3600MHz DDR4 in 3200 mode, what would be the loss? Thanks!
Non-game? You won't ever see gaming. A handful of FPS might reach about 10%, which varies with RAM settings.
Thanks for the feedback! I managed to capture those insights on my own, but I'm curious—would this fit well in a Linus video focused on broader testing? How about exploring its links to speed, latency, and over/underclocking?
It seems to be about gaming channels. Other platforms have handled similar matters. You can share your idea in the discussion thread.
Clocks are the top priority, then timing matters most. 3600MHz CL16 outperforms 3600MHz CL18, but 3200MHz CL14 remains slower despite tighter timing. RAM speed varies widely due to many factors, making performance per build unique. The same setup can behave differently across different motherboards because of unavoidable timing quirks specific to each board. RAM behaves differently on Intel versus AMD Ryzen systems. On Intel, higher speeds are preferable, though gains slow down significantly at extreme frequencies. With Ryzen, performance hinges on matching the clock speed—typically 3600MHz–4000MHz depending on model and chip quality. Lower numbers often hurt more than higher ones. Ultimately, peak performance counts, but not every task demands hitting those absolute limits. Unless your application is memory-intensive, slower RAM can still deliver comparable results.
