SiSoft Sandra 2014 SP3
In the Sandra memory tests, the Corsair Dominator Platinum DDR4 modules are slightly outperformed by the Vengeance modules at 2133MHz speeds, but blow them away when running at the 3200MHz speed. However, the optimizations Corsair engineered into the Dominator Platinum modules becomes apparent with their lower measured latency numbers.
AIDA64 Extreme Edition
The Dominator Platinum module performance with the AIDA64 memory benchmarks mirror those seen in the Sandra benchmarks, further validating the Sandra results. The AIDA64 tests show slightly lower transfer rates at stock 2133MHz speeds, but illustrate the better latency numbers of the Platinum modules.
7-Zip is an open-source file compression and decompression software. File compression and decompression are very system and memory intensive, acting as a good indicator for system performance. The 7-Zip benchmark test was run with a 192MB dictionary size, 16 CPU threads active, and for 5 passes per test. The included benchmark test was repeated three times with the highest repeatable MIPS (Millions of Instructions Per Second) scores recorded.
The performance results here are telling of the real-world performance differences that you are likely to see when using the Dominator Platinum modules. The Vengeance modules outperform the Dominator Platinum modules at both stock and overclocked speeds, but this may be more an artifact of the memory size than the module operating speed. The 16B available from the Dominator Platinum modules may be more easily filled and overwhelmed than the 32GB available to the system with the Vengeance modules.
