LG Nexus 5X review: Settling down

Settling down

GSMArena team, 16 November, 2015.

Performance

The LG Nexus 5X is powered by a Snapdragon 808 chipset, which has been paired with an average 2GB of RAM (flagships these days are in the 3-4GB range). The chipset packs two fast Cortex-A57 cores at 1.82GHz and four power-efficient Cortex-A53 cores at 1.44GHz.

The GPU is an Adreno 418, not Qualcomm's best, but much better suited for a 1080p screen than the QHD screens that LG pairs it with.

Starting off with full system performance, Basemark OS II 2.0 ranks the Google phone quite close to the top-of-its-class Galaxy S6 edge.

AnTuTu 5 places the Nexus 5X somewhere between the old Nexus 5 model and the Galaxy S6 edge.

The processor speed has gone up noticeably since the Snapdragon 800 days.

The HTC One A9, which runs Android 6.0 Marshmallow on a Snapdragon 617 chipset (octa-core Cortex-A53) lags well behind the Nexus 5X. If you ask us, the pricey HTC smartphone should have been equipped with a Snapdragon 808 to begin with.

Single-core performance is almost on par with the Galaxy S6 edge (same cores, different clockspeed) and even the multi-core performance is very good. Compared to the Snapdragon 810-packing Xperia Z5 Compact (two extra Cortex-A57 cores), the total result isn't very different.

The difference in raw processing power between the Adreno 418 (Nexus 5X) and the Adreno 430 (Xperia Z3 Compact) can be seen quite clearly in the off-screen graphics benchmarks results. Depending on the benchmark the gap can be quite massive - especially when the latest OpenGL ES 3.1 is involved.

At its native 1080p resolution, the Nexus 5X should provide enough oomph for 3D gaming (benchmarks are always much harder than games). You can see that the LG G4 struggles at native resolution and rendering at a lower one would negate the benefit of its QHD screen.

The JavaScript performance is well optimized and is about as good as Androids manage (the iPhone is well ahead).

In general web browsing the Nexus 5X beats most other Androids, even the Sony Xperia Z5 Compact, which boasts the beefier chipset (S810 vs. S808) and only has to render the web pages at 720p resolution.

The LG Nexus 5X provides great performance for its price, even getting into competition with 2015 flagships. The processor isn't the fastest, but comes close enough to modern flagships, even outperforming more expensive handsets. Similarly, the phone does great for 3D gaming and web browsing.
