Test Setup And Methodology
Test System Specs
We decided that in order to give a fair and reasonable picture of performance variance, we should test with a variety of different devices. From Qualcomm, we included last year’s Nexus 4 with the Snapdragon S4 Pro along with the currently mid-range Snapdragon 600 in the HTC One. The LG G2 was also included as it carries the same high-end Snapdragon 800 chipsets as the Nexus 5. The recently reviewed EVGA Tegra Note 7 brings Nvidia’s Tegra 4 SoC to the table, while Apple's iPhone 5s shows off the latest iPhone’s A7 SoC.
Nexus 4 was added to show that Android 4.4 optimizations can't and won't make that older device run at the same level as these newer chipsets. It's a sanity check, if you will. The reason LG's G2 was added was to illustrate the performance deficiencies of our retail-purchased Nexus 5. As we will demonstrate, when the benchmarks aren't being hampered by the slow CPU core of this specific Nexus, its Adreno 330 can compete and in some cases even beat the best of performers.
Both Nexus devices are running Android 4.4.2 KitKat, while the Tegra Note, LG G2, and HTC are all running Android 4.2.2 Jelly Bean.
