Compare RAM timings
Compare two DDR memory specifications in nanoseconds and separate timing arithmetic from real workload performance.
MT/s and timings belong together
DDR5-6000 CL30 has a calculated CAS interval of 10 ns. DDR5-6000 CL36 is 12 ns. Those numbers describe one memory operation; they do not predict game FPS, complete memory latency or whether a kit will work in your PC.
How the comparison works
- Memory clock
- DDR data rate ÷ 2 = clock frequency in MHz.
- Time per clock cycle
- 2,000 ÷ data rate in MT/s = nanoseconds per cycle.
- Timing interval
- Timing cycles × time per cycle = CAS, tRCD or tRP interval in ns.
- Theoretical rate per 64-bit data path
- Data rate × 8 ÷ 1,000 = GB/s. This is arithmetic for 8 bytes per transfer, not measured system bandwidth.
Optional timings remain unknown when left blank. The tool does not add timings into a universal access-latency value, infer channel mode from module count, or compare stability and capacity.
Use the operating settings when investigating a PC
A kit’s advertised profile and the active firmware settings can differ. Compare the same kind of data in both columns. Verify DDR generation, capacity, slots, exact CPU/board support and the kit profile before buying or changing settings.
