Unigine Superposition 1080p Extreme

The GPU bound Unigine shows us that the PCIe throughput is perfect, and there’s no “throttling” going on for our 1080 Ti. Overclocking took the score from 5512, up to a very nice 5540.

WPrime 32M and 1024M

The bigger CPU core counts bring big benefits to WPrime, and moving to six cores for the i5 saw some great improvements. 174.302 is incredible for a stock consumer level CPU. Overclocking saw that time drop to around 143 seconds.

Cinebench R15

While the i7 or i9 CPUs are best for CineBench, or the AMD Threadripper, the i5 did set a respectable score of 1035. The single core performance was promising too, hitting 187. Once overclocked, it scored a mighty 1321, a 24.27% increase in performance.

Handbrake MP4 to MKV Conversion 4K

Once overclocked, the CPU managed to hit just over 60 FPS while converting 4K video. That’s very impressive, and for 60 FPS video, it means we’re converting in real time; not bad for the mid-range i5.
