Manufacturer: Intel

Frametimes DDR5-6000 vs DDR5-2400

Let's start with a worst case scenario first: Our baseline DDR5-6000 against the DDR5-2400 config, which is academically interesting, but won't happen in real-life—DDR5 kits start at 4800 MHz. twice of what's tested here.

DDR5-6000 vs DDR5-4800 CL40

Now a more realistic test: DDR5-6000 vs DDR5-4800 CL40, which is pretty much the slowest memory kit config on the market. Really not a lot of differences, mostly just a bit higher frametimes, but no noteworthy additional spikes or jitters compared to DDR5-6000.
