AnTuTu is a benchmark designed to test the performance capabilities of four major aspects of mobile devices: Graphics (encompassing 2D, UI, and basic 3D), CPU (fixed, floating-point, and threaded), RAM (read and write), and I/O (read and write).
We can already see limits of this particular Nexus 5 in terms of CPU speed. It should be ahead of the HTC One, and at least somewhat level with its nearest equivalent, the LG G2 (another Snapdragon 800-equipped handset). However, it tests notably slower in pretty much every metric, and that's due to the nature of how AnTuTu's whole testing process is indelibly tied to the CPU core performance. Once that suffers, everything else does too. What's interesting is that this Nexus 5's Adreno 330 is measurably faster than the HTC One's, but not nearly as fast as it should be. Nvidia's previous-gen Tegra easily leads over the LG G2 and HTC One, but remember that it's also in a tablet form factor more forgiving of thermals.
Chainfire’s (developer of SuperSU, among other recognized Android tools) CF-Bench Pro is designed to characterize the performance of multi-core systems by simulating loads in Java, both in terms of natively-compiled and managed code. It tends to be a decent indicator of the tweaks vendors make to Android to try and eke out extra performance by optimizing for specific hardware features.
At first glance, this looks the same sort of result as the previous benchmark, with this Nexus 5 sitting below the HTC One, and it predominantly is, except that our Nexus 5 turns in an almost abysmal Java score that only marginally faster than the Nexus 4's. Yet, the this unit also manages to beat the HTC One in terms of Native code execution, and also comes within 20% of the LG G2.
Primate Labs’ Geekbench is somewhat of an industry standard due to its comprehensive database and wide cross-platform compatibility, supporting x86 Windows, PPC and x86 OS X, Linux, iOS, and Android. While Geekbench is more of CPU performance benchmark, it also covers some general memory performance. Geekbench’s approach is based on real-world applications and simulations of common tasks like file/data manipulation, compression, encryption, and image processing.
Seemingly out of nowhere, the Nexus 5 gives us its peak performance. We had to wonder if the phone was experiencing some sort of thermal issue in the previous benchmarks, so we tested with an IR thermometer and found nothing out of the ordinary; the Nexus 5 hit the same nominal temperature of 41-43 degrees Celsius observed in our other tests. The readings were taken across the back, where this unit consistently gets the hottest.
And here we go again. It's been proven elsewhere that Qualcomm's quad-core Snapdragon 800 beats Apple's dual-core A7 in threaded floating-point tests, and that outcome is reflected here. Except, what happened to LG's G2?
Let's have a look at a similar test and see if we can't find a parallel.
Principled Technologies’ MobileXPRT is not dissimilar to certain aspects of Geekbench in that it simulates real world applications and use cases. Where it differs is twofold: first, it’s Android-only, and second, it simulates some more modern aspects that Geekbench doesn’t, namely Biometrics (Facial Recognition), UX (List Scroll, Grid Scroll, Gallery Scroll, Browser Scroll, Zoom, and Pinch to Zoom), and Photo Management (Apply Photo Effects, Create Photo Collages, Create Slideshow, and Organize Photos).
This turns out pretty similarly. Sure, some of the ordering changes slightly, and iPhone 5s isn't tested, but our supposedly-slower Nexus 5 takes the lead again. These tests were run sequentially right after the previous set, so whatever caused this Nexus to operate at full capacity was also in effect here.
