Performance: Part 2
All storage tests on the X299 Killer are about as high as on the X299 Extreme4. There are little differences but nothing really significant.
The same as on the Extreme4, also the Killer performs great using SATA SSD. 565MB/s is about the best result we’ve seen and another ASRock motherboard repeats it!
NVMe tests are a bit worse than on the Extreme4. The Killer’s maximum bandwidth is slightly below 3000MB/s. Of course, it’s also high result and as good as that declared by SSD manufacturer.
ATTO USB 3.0/3.1 tests are one more time the same as on other ASRock motherboards, achieving about 408MB/s on our Lexar drive.
UL benchmarks like 3DMark Time Spy or VRMark are showing us great results. Pretty much the best results so far on the X299 motherboards. We will still review one more ASRock X299 motherboard in a couple of days but I don’t think that results will be much better. On the other hand, the improvement over other motherboards is barely visible but also repeatable. I guess that overclockers care about these couple points more than gamers but it’s still worth to mention.
Also overclocking of CPU and memory is on a high level. Below you can see our PCMark and 3DMark results at 4.7GHz with 64GB of RAM at DDR4-3600 CL16. Higher processor frequency is possible but because of limited cooling, it’s not possible to keep this processor stable under full load at more than 1.25V. Even this voltage makes it use over 300W when it’s fully loaded.
Our results simply prove that the motherboard can handle higher frequency than even the best air or water cooling.
ASRock X299 Killer SLI/ac performs well in all our tests and there were no issues with stability or compatibility. I guess that every gamer or PC enthusiast who requires set of features that the Killer offers will be satisfied as it’s a solid base for high-end PC and so far the only difference between other ASRock X299 motherboards are additional features that make life easier but also cost some more.
