Performance
Performance has been tested on the Intel platform, including the Core Ultra 7 265K processor, ASRock Z890 Taichi OCF motherboard, Colorful RTX4080 Advanced OC 16GB graphics card, Kingston Renegade 2TB NVMe SSD, and FSP 1350W 80+ Platinum PSU.
All results were performed on the FURY Renegade RGB 48GB DDR5-8400 memory kit. Our overclocking limit was DDR5-9333, but overclocking is not guaranteed. At this clock, the FURY Renegade could run at relatively tight timings like CL44-56-56 and slightly higher voltages than in XMP profiles – 1.50V VDD/VDDQ.
Let’s begin the tests.
At the XMP-8400 profile, we could reach 123GB/s in the memory read, 100GB/s write, and 107GB/s copy. It’s a pretty good result, considering that the sub-timings for high-capacity memory are more relaxed. The result is about as high as that of UDIMM. However, as I mentioned, it’s very easy to achieve, while barely anyone can do that on UDIMM and maintain complete stability.
The latency at the XMP profile is not the lowest, but it’s highly affected by the CPU. We still don’t know if it’s a matter of new design or if Intel will improve it with upcoming microcodes, as there are rumors about potential issues that can be solved. Either way, our results are pretty good, as we could go below 80ns at the 8400 MT/s XMP profile.
The overclocked setting loses a lot because anything above 9000MT/s works in Gear 4 mode, which limits the memory controller. In other words, for an average quality CPU, the optimal seems to be 8800MT/s or 9000MT/s and Gear 2 mode. Memory kits at these speeds will be released in a few weeks.
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 differences between popular Microsoft applications. Excel has demonstrated the most significant performance gains in the last generations but is also the most demanding if we use various macros and add-ons. However, we have the most significant performance gains in the new Intel generation in Word. The XMP profile performs well in all tests and, on average, is even slightly faster than overclocked settings at higher frequencies.
3DMark tests don’t show much difference in all settings. This is notable if we participate in competitive overclocking; otherwise, it looks close to an error margin.
The latest Cinebench 2024 shows high performance in all our settings. Much larger workloads should give us better results at faster RAM settings during longer rendering tasks.
Final Fantasy XV and Superposition results are barely different. RAM helps in the FF XV benchmark, but the difference between the slowest and fastest settings is not high.
In modern games, RAM is mainly visible at lower display resolutions like 1080p. It’s still the most popular due to the high average FPS on even cheaper graphics cards, and it’s also optimal for esports. Many new games at 1440p also react well to RAM speed. It’s not as spectacular as at 1080p, but we can see even a 5-7% performance gain because of the RAM. In our comparison, we can see about 5-6FPS gain going from 6400MT/s to 8400MT/s. The overclocked settings are worse than the XMP due to the requirement of Gear 4.
Even though Kingston started at a relatively low frequency for CUDIMM, at 8400MT/s, it also proves that higher settings won’t give us much more, and when we use Gear 4, which is required above 9200MT/s, it can be even slightly worse.
We will try to present higher CUDIMM memory kits in the upcoming weeks. Still, we already expect that the 8800-9000MT/s will be the best option for most users who wish for high performance and full compatibility on even less expensive motherboards.
I will tell you more about the FURY Renegade memory overclocking on the next page.
