Corsair Vengeance RGB PRO DDR4-3600 4x16GB 3000 CL16 vs Patriot Viper Steel DDR4-3600 2x32GB CL20 RGB in detail
True latency
Corsair Vengeance RGB PRO DDR4-3600 4x16GB 3000 CL16 is the lower-latency kit at 10.67 ns, against 11.11 ns for Patriot Viper Steel DDR4-3600 2x32GB CL20 RGB — a difference of 0.44 ns. That figure is what reconciles the two spec sheets: CAS latency counts clock cycles, so it only means something next to the clock it counts. Corsair Vengeance RGB PRO DDR4-3600 4x16GB 3000 CL16 runs 3000 MT/s at CL16; Patriot Viper Steel DDR4-3600 2x32GB CL20 RGB runs 3600 MT/s at CL20.
Transfer rate
Patriot Viper Steel DDR4-3600 2x32GB CL20 RGB is rated 3600 MT/s against 3000 MT/s for Corsair Vengeance RGB PRO DDR4-3600 4x16GB 3000 CL16 — 28800 MB/s per module, against 24000 MB/s. That is peak transfer rate, not access time: reaching a higher clock costs more cycles on each access, which is why the CAS numbers differ too, and why the true latency above is the figure that compares directly.
Kit layout
Corsair Vengeance RGB PRO DDR4-3600 4x16GB 3000 CL16 ships as 4 × 16GB, Patriot Viper Steel DDR4-3600 2x32GB CL20 RGB ships as 2 × 32GB. That is a real difference and not a ranking: more sticks fill more channels on a board that has them, while fewer sticks leave slots free for a later addition. Which suits depends on the board and on whether more memory is planned.
Lighting, timings and ECC
On the lighting question: Corsair Vengeance RGB PRO DDR4-3600 4x16GB 3000 CL16 is published with RGB lighting, and Patriot Viper Steel DDR4-3600 2x32GB CL20 RGB is published with RGB lighting. On the full timing tuple, the numbers that follow CAS: Corsair Vengeance RGB PRO DDR4-3600 4x16GB 3000 CL16 runs 18-22-22-42, and Patriot Viper Steel DDR4-3600 2x32GB CL20 RGB runs 20-26-26-46. On error correction: Corsair Vengeance RGB PRO DDR4-3600 4x16GB 3000 CL16 is published with no ECC, and the catalog does not state whether Patriot Viper Steel DDR4-3600 2x32GB CL20 RGB supports it. Whether ECC is worth having depends on the platform as much as the modules — the board and the CPU have to support it too.
Which to buy
Without a tracked price for both, this page cannot say which to buy — the answer depends on cost, and cost is what is absent. What the specifications do say is that Corsair Vengeance RGB PRO DDR4-3600 4x16GB 3000 CL16 has the lower true latency, 10.67 ns.
Common questions about this pair
- Is Corsair Vengeance RGB PRO DDR4-3600 4x16GB 3000 CL16 faster than Patriot Viper Steel DDR4-3600 2x32GB CL20 RGB?
- Corsair Vengeance RGB PRO DDR4-3600 4x16GB 3000 CL16 is, on true latency: 10.67 ns against 11.11 ns. Corsair Vengeance RGB PRO DDR4-3600 4x16GB 3000 CL16 runs 3000 MT/s at CL16 and Patriot Viper Steel DDR4-3600 2x32GB CL20 RGB runs 3600 MT/s at CL20; the CAS numbers alone do not settle it, because they count clock cycles rather than time.
- Which of these two should I buy?
