LG G3 vs. Sony Xperia Z2: Distance to impact

GSMArena team, 07 July 2014.

Performance

The LG G3 runs on a Qualcomm MSM8974AC Snapdragon 801 chipset with four Krait 400 cores clocked at 2.5GHz each. Graphics are powered by an Adreno 330 GPU, and there is a hefty dose of RAM at 3GB (2GB on the G3 version with 16GB of internal storage). The QHD display should play a factor here for two reasons - the processor and GPU will have to push harder than their 1080p counterparts and most apps (including benchmarks) haven' been optimized for QHD resolution yet.

The Sony Xperia Z2 is also powered by a Qualcomm Snapdragon 801 chipset, the MSM8974AB variety. This means the four Krait 400 cores are clocked at 2.3GHz, the Adreno 330 GPU is identical and there is 3GB of RAM too (across all models).

When it comes to CPU performance, the European LG G3 underperforms like its South Korean version. Using Basemark OS II we see the LG G3 is a hair faster than the Xperia Z2.

Graphics benchmarks was where we expected the G3 to struggle more compared to other flagships. Indeed, in the onscreen Manhattan test the high screen resolution and the high-quality graphics rendered account for what seems to be poor performance.

Other than that, the Xperia Z2 is on par with the G3 on the off-screen graphics tests, while it does better when it comes to on-screen performance due to its lower resolution 1080p display.

Real world graphics can be measured more effectively using the benchmark feature of Epic Citadel. Here, the device is forced to run in native 1440p resolution with Ultra graphics quality, where despite scoring below other flagships, it's still able to achieve a respectable score of 43.2 fps.

BrowserMark 2.1 looks at HTML 5 performance, while Mozilla's Kraken 1.1 is JavaScript-centric. The LG G3 scores well in both tests, which should result in a great browsing experience considering the 5.5-inch screen with 534ppi. The JavaScrpit performance of the Xperia Z2 is on par with the LG G3, while the overall browsing experience is better only on the EU LG G3 model according to the BrowserMark 2.1 test.

Winner: Sony Xperia Z2. While the numbers are close, the G3 falls behind in most of our tests, no matter which versions we tried (3GB and 2GB). Either the QHD screen really takes a toll on all aspects of performance, or LG are having a hard time with this particular iteration of Snapdragon 801.

Also, it's worth noting that the LG G3 has some serious overheating issues, and that the quoted benchmark numbers dropped significantly after just a few minutes of active benchmarking. The Xperia Z2 has overheating issues too, but they start to get noticed only after prolonged use of the camera or in hot weather.
