Performance
Performance has been tested on the Intel platform, which contains the Core Ultra 265K CPU, ASRock Z890 Taichi Lite motherboard, Colorful RTX4080 Advanced OC graphics card, and Deepcool PX1000P 80+ Platinum PSU.
All tests were performed on the Crucial Pro OC 32GB DDR5-6400 memory kit. The 32GB memory kit could overclock up to DDR5-7000 and CL40-52-52 1.35-1.40V, which isn’t anything spectacular but an improvement over the programmed profiles. The DDR5-7000 CL40 setting was stable in our tests. You can expect it from the memory kit if your motherboard and CPU’s memory controller can handle it. Most new processors and motherboards shouldn’t have a problem with that.
Let’s begin the tests.
The AIDA64 memory benchmark scales well with the memory frequency. With each step, we gain a couple more GB/s. The results are not bad but could be better.
The latency is a weak point of the latest Intel processors, so 80ns is about typical for 6400MT/s. What is worth mentioning is that the XMP profiles are between 10-20ns better than the standard 5600MT/s JEDEC memory.
The difference in synthetic bandwidth and latency tests does not always tell the whole story, so let’s examine other tests.
The PCMark 10 Applications benchmark shows the differences between popular Microsoft Office applications. This time, we can see slightly better results at each higher memory frequency, but it’s not as significant as we could see on some other memory kits.
3DMark tests show barely any difference at overclocked settings, but if we take a closer look at scores, it’s clear that higher frequency memory is faster. I don’t think it matters out of competitive benchmarking. The Crucial Pro OC is about as fast in UL benchmarks as memory kits at 6400MT/s and CL30 or CL32.
The new Cinebench reacts slightly better to RAM performance in rendering. It’s insignificant, but we can tell which setting is the fastest, especially though this benchmark is long.
The result at DDR5-6400 XMP is already pretty good. The lower XMP profile is significantly slower.
Final Fantasy XV and Superposition results at high display resolutions are barely different. The difference between the slowest and fastest settings in the Final Fantasy XV benchmark is visible, but the Superposition at 8k display resolution gives us results close to the error margin.
Our results in modern 3D games show that the Crucial memory at 6400MT/s is about as fast as overclocked to 7000MT/s settings. We can still gain up to 6FPS compared to the standard 5600MT/s at JEDEC settings.
The XMP 6000 profile is also not bad, but the new Intel processors like higher frequencies, so we can recommend the Crucial memory series, especially for AMD users, who find 6400MT/s the best for everyday use.
On the next page, I will tell you more about the overclocking of the new Crucial memory.
