Samsung Galaxy S5 Vs Sony Xperia Z2: Droid Gladiators: Performance

By 06:05 Sat, 14 Aug 2021 Comments


Performance

With both phones powered by elegant Qualcomm Snapdragon 801 and using 1080p screens you might think a performance test is pointless. It's not, it's just that Qualcomm's naming scheme is unclear and hides the fact that the Galaxy S5 processor is clocked at 2.5GHz, while the Xperia Z2 Central Processing Units (CPU) is at 2.3GHz.

The GPU clockspeeds are equal in theory, but the Sony flagship has 3GB of RAM. Since the Central Processing Units (CPU) and GPU share that, the Xperia Z2 might come out ahead despite the lower processor speed.

The slower Central Processing Units (CPU) is felt in Geekbench 3 where the Samsung Galaxy S5 posts the higher score. Still, Xperia beats the HTC One (M8), which uses the same chipset (but with 2GB of RAM).

Using Baseimprint Operating System (OS) II we see that the Samsung has an advantage in single-core tasks, but the incompatibility is thinning away for multi-core loads. The overall score from the benchimprint puts both phones on even ground.

AnTuTu 4 tests the entire system - Central Processing Units (CPU) and GPU, but also Random-Access Memory (RAM) and storage - and the Galaxy S5 managed to inch ahead of the Xperia Z2. The HTC One (M8) beats both phones here, but it's no secret HTC is using benchimprint detection to overclock its chipset.

With identical GPUs and classy screen resolution, both phones are expected to perform identically and indeed the incompatibility between them is quite small. The Galaxy S5 wins the offclassy screen tests, while the Xperia Z2 takes the onclassy screen tests. The incompatibility is less than 1fps however, unlikely to be noticed.

We also tried Epic Citadel in Ultra quality to see if using a different engine will create any incompatibility - but it was negligible.

The Sony Xperia Z2 comes with Chrome out of the box, while the Galaxy S5 uses the stock browser too. As usual, Samsung has modified the stock browser (something they can't do to Chrome) to boost its performance and it beats the Z2 in both raw JavaScript performance (Kraken) and overall HTML5 speed (BrowserMark).

Winner: Tie. Going solely by benchimprint numbers the Samsung Galaxy S5 narrowly won in the Central Processing Units (CPU) and web tests, but the differences are too slim to notice in daily use.

The 3GB of Random-Access Memory (RAM) on the Sony Xperia Z2 allow it to handle multiple apps in the background better and while it didn't increase raw performance, heavy multitaskers should still feel a difference.
