Performance
Performance has been tested on the latest AMD platform, including the Ryzen 9 7950X processor, ASUS Crosshair X670E Gene motherboard, Colorful RTX4080 16GB graphics card, and Lian-Li SP850 850W Gold 80+ PSU.
All results were performed on the Crucial 32GB DDR5-5600 memory kit. The memory kit could work at DDR5-6400 but, from time to time, was showing instability (which could be related to the test platform). The DDR5-6200 CL32 setting was fully stable, confirmed by hours of various tests.
Let’s begin the tests.
The fastest setting and the optimal performance we could see at DDR5-6000 CL32, even though the memory kit could work at DDR5-6200. The higher frequency required some sub-timings to be set at slower values.
The EXPO profiles are not as fast as overclocked settings, mainly because of the lower frequency.
The latency at the EXPO 5600 profile is already about 10ns better than in standard memory kits. It’s also 10-15ns slower than the overclocked settings. On the other hand, the fastest memory kits on the market designed for AMD chipsets are usually not better than 65ns.
The difference in synthetic bandwidth and latency tests does not always show the whole story, so let us take a look at other tests.
PCMark 10 Applications benchmark shows us differences in popular Microsoft Office. The most significant performance gains can be seen in Excel. It’s also the most demanding if we use various macros and add-ons.
3DMark tests show a clear performance bump at overclocked settings. It wouldn’t matter in gaming, but in competitive benchmarking would be significant.
Rendering benchmarks like Cinebench R23 show some gains too, but it’s hard to tell if the faster RAM is really so much better. All the settings perform well in this benchmark. If we were working on projects requiring rendering, then probably higher RAM capacity would give us more than the memory performance.
Final Fantasy XV and Superposition results are also barely different. We can tell that RAM helps, but the difference between the slowest and fastest settings is not much higher than the error margin.
In games, we can finally see the expected performance gain. At a lower display resolution, we can count on even 40FPS better results because of faster memory settings. With the higher display resolution and details, RAM is starting to be less important, as DDR5 is already fast enough.
Crucial DDR5 is clearly not the fastest memory on the market, but it has other advantages. In some scenarios, we won’t see the performance difference, while we can save a lot of money. The tested memory kit for sure has overclocking potential, so if we still need better results, then we can try our luck in overclocking.
