To get a feel for how graphics performance on the ZenFone 2 compares to other devices, we used GFXBench, which has been one of our standard graphics performance benchmarks for a while. In order to ensure Vsynch and resolution isn’t a limiting factor, we compare offscreen test results. We also used Futuremark's 3DMark Ice Storm Unlimited benchmark.
The scores here prove that this isn't the gamer's phone per se. It struggles to keep pace with other high-end and mid-range devices, and might not always fare as well on the latest titles. It should be noted, however, that we never noticed any graphical hiccups in standard app use.
GPU testing puts the ZenFone 2 about in the middle of the pack, though it’s really only the Qualcomm Snapdragon 810-based HTC One M9 with a sizable lead. The ZenFone 2 is within striking distance of high-end devices like the Galaxy S 6 in the 3DMark Ice Storm test in terms of graphics performance, but physics performance is second from the top thanks to its Intel Atom SoC.
