HTC Desire 616 benchmark performance was pretty decent as expected from its octa core processor and powerful GPU. Although it does have the powerful octa-core Mediatek MTK 6592 chipset. But for some reason HTC decided to down clock or under clock it to 1.4GHz from its default clock rate which is 1.7GHz and in some phones like Micromax Canvas Gold it is over clocked to 2GHz. As a result of that HTC Desire 616 scored a little less in benchmarks than those phones.
It also comes with only 1GB of RAM out of which you’ll only get around 200-300MB free to use. Rest is used by the OS/UI. And also most of the octa core smartphones comes with on-board storage which is faster to access in general than a class 4 micro SD card. So, these are also some factors that effected its score in benchmarks, comparatively.

Gaming wise the underclocked CPU doesn’t effect the performance much. In fact since the device doesn’t get much hot it actually performs better. For instance in Micromax Canvas Gold the phone gets so hot while playing GTA San Andreas on max settings that CPU eventually throttles out and creates a major lag during gameplay sometimes the game even crash. Not always though, only in most rare cases. But the lag is frequent. San Andreas on maximum settings actually performed better on HTC Desire 616 than most of the octa-core phones that i have played it on. Rest of the games like Asphalt 8 and Modern Combat 4 ran well too all thanks to the respectable Mali 450MP GPU.
It does support move to sd and default write location, so you won’t have much problems installing big games on this phone.
