Performance
Performance has been tested on the Intel Rocket Lake-S platform, which contains the i7-11700K processor, MSI Z590I Unify motherboard, and ASRock RX 6800 XT Phantom Gaming graphics card. Used OS is Windows 10 x64 and the latest updates.
Our comparison includes overclocking results and settings where the Viper Elite II 16GB and 32GB DDR4-4000 memory kits were stable. Like in the previous Patriot review, graphs include single-rank (16GB) and dual-rank (32GB) kits results.
As usual, we will start with AIDA64 Cache and Memory benchmark, which is probably the best software for synthetic memory speed tests.
AIDA64 Memory and Cache benchmark shows that the dual-rank, 32GB kit is slightly faster in the direct comparison. The most important in daily work is a memory copy result, where we can clearly see the difference.
Even though both memory kits have quite relaxed timings in the XMP, the results are still good. We can also see pretty low latency, even though all settings have CL18 or more.
In the Cinebench R20 benchmark, results are close to each other, and we can’t clearly say if one setting is better or it’s a margin error.
PCMark 10 is reacting well to memory performance. Our results are not much different, but we can clearly tell which setting is the best. In the Productivity test, the dual-rank, 32GB kit shows better results at all settings.
3D benchmarks from UL are showing a bit better results on the 16GB kit, but both are quite close to each other. The difference can be caused by more relaxed sub-timings of the higher capacity kit.
In VRMark, we can see a similar connection between memory settings and the test’s difficulty. Except for the Orange Room test, all other results are about the same in all settings.
The Final Fantasy XV and Superposition 8K Optimized benchmarks are acting almost the same as 3DMarks. The 16GB kit is sightly faster in these tests.
Lower frequencies and XMP profiles are even the fastest in both benchmarks.
Modern games like Shadow of the Tomb Raider or FarCry 5 show mixed results, so it’s hard to say which memory kit is faster at overclocked results. At XMP settings, the dual-rank kit is about 2-3FPS faster. Considering that we are close to 170FPS, I don’t think it would matter much while playing these games.
Both memory kits are performing better than expected, which can be caused by how modern platforms work. It suggests that even more standard XMP profiles at optimal frequencies can give us high performance without spending much money.
