Performance
Performance has been tested on the Intel Rocket Lake-S platform, which contains an i7-11700K processor, MSI Z590I Unify motherboard, RX6800 XT graphics card, Silicon Power US70 1TB NVMe SSD, and Abkoncore 850W 80+ Gold PSU.
All results have been made using the Team Group Dark Z FPS 16GB DDR4-4000 memory kit. All overclocking results were stable and passed multiple tests, as listed in the comparison. Overclocking is never guaranteed, but it suggests how the memory kit can work.
As usual, we will start with the AIDA64 Memory and Cache benchmark, which is probably the best application to check memory bandwidth and latency.
AIDA64 bandwidth results are showing how well the memory is scaling with frequency. The better the memory controller, the higher the performance gain. With the latest Intel Rocket Lake-S processors, we can count on better memory support and higher overclocking. Results at XMP settings are already high, while DDR4-4800 settings bring us to the level available on quad-channel chipsets.
The XMP also has low latency, which is one of the main features of the Dark Z FPS. Results would be even better if we could run the memory controller at Gear 1 mode, but this is limited to about DDR4-3600, and barely any CPU can make more.
In PCMark 10, all settings have similar results. The XMP is even the best in the Essentials test. Most differences are, however, at the edge of the error margin.
Cinebench R23 is more demanding than the previous versions and is also longer. It doesn’t react very well to the memory settings but still suggests higher performance. The XMP looks good in this comparison.
3DMark series benchmarks are showing similar results in all settings. We can tell which one is higher or lower, but most are closer to the error margin. The only clear difference is in the Fire Strike Extreme test, which is the easiest for the graphics card and reacts the best to RAM performance. The XMP performs well and competes with the overclocked settings without issues.
VRMark usually reacts better to memory settings, while now we can see only up to 5FPS difference in tests where is already about 300FPS. Even though it’s a repeatable result, it’s hard to say which setting is the best clearly.
Usually, we can see a higher difference between memory settings in Final Fantasy XV Benchmark. Still, in this case, both benchmarks at high display resolution, so Final Fantasy XV and Superposition are not showing any special differences, regardless of the settings.
As usual, popular games are showing the highest differences, but in this case, it’s mostly FarCry 5, where depends on the settings, we can count on up to 8FPS gain. The XMP profile is not far behind, losing about 1FPS to most other settings. I have to add that all settings are far faster than whatever you can buy in stores.
Dark Z FPS DDR4-4000 seems well-balanced. It’s fast in all our tests at XMP settings and offers high overclocking potential. On the next page, I will tell you some more about overclocking of this exceptional memory kit.
