LG G2 vs. Samsung Galaxy Note 3 vs. Sony Xperia Z1: The triumvirate

Performance

We'll now analyze the performance of the three Snapdragon 800-wielding beasts. Here are the profiles of the competitors.

	Sony Xperia Z1	LG G2	Samsung Galaxy Note 3
Chipset	Snapdragon 800	Snapdragon 800	Snapdragon 800
CPU	4x Krait 400 @ 2.2GHz	4x Krait 400 @ 2.26GHz	4x Krait 400 @ 2.27GHz
RAM	2GB	2GB	3GB
GPU	Adreno 330	Adreno 330	Adreno 330
OS version	Jelly Bean 4.2.2	Jelly Bean 4.2.2	Jelly Bean 4.3

Only minor differences are to be expected - the Galaxy Note 3 and G2 have slightly higher clock speed at 2.27 GHz and 2.26 GHz, respectively, while the Sony Xperia Z1 has its four Krait cores running at 2.2 GHz.

The RAM is 2 gigs for the Sony and LG flagships, while Samsung has made the world's first smartphone with 3GB of RAM, which should give the Galaxy Note 3 an edge when it comes to multitasking. And finally, due to it being a Jelly Bean 4.3 smartphone, the Galaxy Note 3 has OpenGL ES 3.0 support so it should show better graphics performance for apps and games that are designed to take advantage of that.

We'll start with BenchmarkPi, which measures the calculative performance of the CPU cores. The Galaxy Note 3 and G2 tie for first place here, probably due to their higher clock speed, while the Xperia Z1 is close behind.

Now it's time to look at browsing performance. SunSpider tests out JavaScript performance, while BrowserMark 2 focuses on HTML 5 and Vellamo is an all-round benchmark. JavaScript saw the Galaxy Note 3 well in front with the Xperia Z1 and LG G2 in second and third place, respectively. HTML 5 performance saw the LG G2 and Sony Xperia Z1 trade places as the Galaxy Note 3 retained its lead.

The Galaxy Note 3 failed to impress in the Vellamo test, dropping to third, even if it was close to the Xperia Z1 and the G2 in front.

Keep in mind that scores aside, all three smartphones are in a league of their own when it comes to performance. There's no lag to be found anywhere, pages load quickly, animations are super fast, games start in an instant and run perfectly and all those pixels are being pushed to the screen effortlessly.

Whichever of the three you go with, you'll never feel like it's slower than the other two - Snapdragon 800 and Android Jelly Bean will see to that.

Winner: Samsung Galaxy Note 3. The extra gig of RAM and the newest Android version saw the Samsung Galaxy Note 3 dominate most benchmarks and when it wasn't in the lead it wasn't too far behind.

Runner-up: Sony Xperia Z1. The Sony Xperia Z1 has a minor disadvantage in terms of clock speed, but managed to edge out a victory thanks to its GPU and memory performance, which was a tad better than that of the LG G2.

Third place: LG G2. A stellar performer in its own right, the LG G2 come a tad short of its rivals here.
