Performance
Performance has been tested on the Intel Rocker Lake-S platform, which contains a Core i7-11700K processor, MSI Z590I Unify motherboard, ASRock RX6800 XT graphics card, Silicon Power US70 1TB NVMe SSD, and Corsair SF600 600W 80+ Platinum PSU.
All results have been made using the Predator Vesta RGB 32GB DDR4-3600 memory kit. All overclocking results were stable and passed multiple tests, as listed in the comparison.
As usual, we will start with the AIDA64 Memory and Cache benchmark, which is probably the best application to check memory bandwidth and latency.
AIDA64 bandwidth results are high, even at the XMP profile. Overclocking results are exceptional, as expected. Since it’s a dual-rank memory kit then it can’t overclock as high as single-rank kits, and we were limited to a DDR4-4266 which is great results nonetheless.
Latency results are pretty good, while DDR4-4000 and DDR4-4266 are significantly losing because of the Gear 2 mode. Our test motherboard can’t run at Rank 1 above DDR4-3733. The difference isn’t as high as on AMD motherboards, but is still clearly visible.
In PCMark 10, the best results are at DDR4-4266, but all other settings are not far behind.
3DMark series benchmarks are showing similar results in all settings. We can tell which one is higher or lower, but most are closer to the error margin. DDR4-4000 and DDR4-4266 are slightly faster in these tests than lower RAM frequencies, even though they run at Gear 2 mode.
In VRMark, we can see a 1-2FPS difference between all our settings. This is about the same as we could see in some earlier reviews.
The same barely visible differences are in Final Fantasy XV and Superposition benchmarks. We can’t make much more to gain higher performance on these fast platforms with already fast RAM. On the other hand, users expect to buy the best possible components and play games at optimal settings without wasting on manual tunning.
Results in benchmarks based on popular games are slightly better than on single-rank memory kits. We can see up to a 6FPS gain because of overclocking. It would be more if our memory kit hasn’t have already a fast XMP profile. On the other hand, I highly doubt that overclocking would improve the user’s experience.
For those who always want more, we have a couple of words about overclocking on the next page.
