Performance
Performance has been tested on the Intel platform, including the i7-14700K processor, ASUS Z790 APEX motherboard, Colorful RTX4080 Advanced OC 16GB graphics card, Kingston Renegade 2TB NVMe SSD, and DeepCool 1200W 80+ Platinum PSU.
All results were performed on the V-Color XFinity 48GB DDR5-8400 memory kit. Our overclocking limit was 8600MT/s, but it wasn’t entirely stable, so we skipped it in the comparison.
We will start with the AIDA64 Memory and Cache benchmark, probably the best application for checking memory bandwidth and latency.
The results in the AIDA64 benchmark almost always look better at higher frequencies and tighter timings, but as I mentioned earlier, we couldn’t keep full stability at more than 8400MT/s so the highest setting is the XMP profile from our memory kit. The XFinity memory kit performs well at the XMP profile. The performance can still be improved at 8400MT/s if we have the time for manual tweaking. On the other hand, results at 8400MT/s are close to those of 8200MT/s CL38 kits.
The latency in the XMP settings is pretty good. We could expect it to be lower, but without further tweaking, it’s never much better than mid-65ns. Playing with a few timings, we can go down to around 55ns.
AIDA64 tests are fully synthetic and usually do not present real-world performance. The following tests should give a better view of the daily performance.
PCMark 10 Applications benchmark shows that the performance gain from further overclocking isn’t significant and can be a waste of time. The V-Color memory performs excellently on the XMP profile. We can see that the higher frequency memory is slightly faster in PCMark 10, but nothing that would significantly affect our work experience.
The same story can be seen in 3DMark benchmarks. Higher RAM frequency results are barely better.
Cinebench 2024 is not any different. Even though we see higher results at a higher memory frequency, they do not change much if we translate them into daily workloads. The same as in previous tests, the memory is scaling much better up to about 7600MT/s, while above that, it is better, but not spectacular out of synthetic bandwidth tests.
The same Final Fantasy XV and Superposition benchmarks have all results close to the error margin.
Results in games finally show something higher. Less demanding titles or low display resolutions can take advantage of faster RAM. More demanding games at high display resolutions push graphics cards to the limits and don’t rely so much on the CPU or RAM. Then, the FPS gain is not so significant. We can see that the average FPS in Cyberpunk 2077 at 1080p can improve even by 14 FPS, and we started from already pretty fast 6400MT/s memory.
The XFinity 8400MT/s is the fastest memory kit we tested. However, it’s faster than the current generation of hardware can handle, causing stability issues at too high frequencies and not much better results than the lower memory kit series. The V-Color Manta XFinity is still the top memory for enthusiasts and overclockers, who will for sure appreciate everything this memory has to offer.
I will tell you more about overclocking on the next page of this review.
