Performance
Performance has been tested on the Intel Rocket Lake platform, including the i7-13700K processor, ASUS Z790 APEX motherboard, Colorful RTX4080 Advanced OC 16GB graphics card, Kingston Renegade 2TB NVMe SSD, and Corsair 1200W 80+ Platinum PSU.
All results were performed on the ADATA Lancer RGB 32GB DDR5-7200 memory kit. Our overclocking limit was 8400MT/s, but overclocking is not guaranteed. At this clock, the memory could run at respectable timings of CL38-48-48 at the 1.55V VDD/VDDQ. Since the voltage can be too high for daily usage, I recommend staying at 7600 or 8000MT/s, which offers similar performance and runs at much lower voltages.
Let’s begin the tests.
At the XMP profile, we could easily pass 110GB/s in all the tests. It’s a pretty good result considering that the frequency could be even higher. 7200MT/s is also the maximum supported by most Z790 and B760 motherboards on the market.
The latency at the XMP profile is quite good. Overclocked settings are always better in latency tests as we can adjust timings that are not always guaranteed to be stable. RAM manufacturers play safe to provide full compatibility with various motherboards. At the highest overclocked profile, we could go down to 55ns, which isn’t the best we could do, but for review purposes, we decided not to use a hard-to-set profile.
The difference in synthetic bandwidth and latency tests does not always show the whole story, so let us 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. All our profiles are fast, so seeing the performance gain at the fastest settings is hard.
3DMark tests aren’t showing much of a difference in all settings. Even for the competitive overclocking, the performance gain isn’t so significant.
Rendering benchmarks like Cinebench R23 also show some gains, but it’s hard to tell if the faster RAM is so much better. Much larger workloads should give us better results at faster RAM settings during longer rendering tasks.
Final Fantasy XV and Superposition results are also barely different. We can tell that RAM helps in the FF XV benchmark, but the difference between the slowest and fastest settings is not high.
We will see the most significant gains at a high RAM frequency in modern games at lower display resolutions. We can especially see it in Tomb Raider at 1080p. Higher display resolutions use more graphics card power and are scaling worse with RAM performance. We can still see up to 11 FPS gains in FarCry 6 and 5 FPS in Assassin’s Creed. The FarCry 6 result is quite surprising as we usually don’t see more than 3-4 FPS.
ADATA XPG Lancer is already fast at the XMP profile, so it doesn’t require further overclocking. We can enjoy optimal results at a one-click setting without the hassle of manual adjustments. However, if we wish to push it some more, then there is no problem to do that, as the overclocking headroom is pretty good. I will tell you some more about overclocking on the next page of this article.
