Shortly after the MT6592 started rolling out, people thought that Snapdragon 801 devices were far superior due to the higher AnTuTu score. But that was not entirely the case... After testing my Idol X+ (with the 2GHz MT6592) using various versions of AnTuTu, it turns out the Qualcomm was covering up their weak CPU performance with crazy high graphics scores. The MT6592 completely smokes the SD801 when it comes to CPU speed. In fact, newer phones like the LG G4 and HTC One M9 have weaker float performance than my phone (my phone also smokes the Note 4 on integer speed, but sadly not on float point speed). You guys may be asking why MT6592 phones are not as snappy as Snapdragon devices. The answer probably lies in the fact that most mediatek devices rely on the hotplug scaling governor, which can be quite stubborn and, in extremely rare cases, sluggish on octa-core devices. Also, at least in my case, the stock ROM comes with some small and nearly unnoticeable bugs and has strict thermal throttling. The stock ROM is also not optimised as well as on SD801 flagship devices. To put this all in a few words, the MT6592 wins the CPU race against the SD801, but utterly loses when it comes to graphics speed.
