Samsung Galaxy Mega 5.8 review

Synthetic benchmarks

The Samsung Galaxy Mega 5.8 uses a dual-core Broadcom SoC clocked in at 1.4 GHz alongside a VideoCore IV GPU. While we have seen the Broadcom chipset before in a Samsung device (most notably in the Samsung Galaxy S II Plus), we haven't seen it clocked at 1.4 GHz. It's curious why Samsung chose the generally low-end Broadcom chipset for the Galaxy Mega 5.8 while sticking to a far more capable Qualcomm Snapdragon SoC for the Galaxy Mega 6.3, but we assume price is a factor.

With the notable exception of web browsing, it's been our experience that the Broadcom SoC generally performs worse than its Qualcomm equivalents - even those with lower clock speeds - so we're not expecting anything spectacular in terms of performance.

BenchmarkPi tests single-core CPU performance, and the 1.4 GHz processor scores towards the bottom of the pack in this benchmark, right around the previous generation Samsung flagship, the Galaxy S III.

The AnTuTu CPU benchmark is where the Mega 5.8 really struggles. Granted, it's pitted against mostly quad-core competition, but the device is far behind the pack by a large margin.

We ran GLBenchmark off-screen, which means we're testing at a fixed resolution, which lets us test the raw GPU power. The VideoCore IV is one of the less popular mobile GPU's around, and the one found in the Galaxy Mega 5.8 did not impress.

But most games are rendered at native resolution, so we're including Epic Citadel, which uses Unreal Engine 3 - a popular game engine for mobile developers. Here, the Galaxy Mega 5.8 matched the performance of the other devices and just as them often ran into the 60fps limitation of its screen, so you can count on pretty great gaming performance.

Broadcom chips usually punch above their weight when it comes to web browsing performance, and the one inside the Galaxy Mega 5.8 is no exception. In both the Sunspider and Browsermark 2 web benchmarks, the phablet scored towards the top of the charts - a notable improvement over the previous benchmarks.

With the exception of web browsing, we were generally the Galaxy Mega 5.8 chipset is hardly anything worth writing home about. Whether it's due to getting better dual-SIM performance or simply cutting down on costs, the Broadcom chipset used by Samsung in the Galaxy Mega 5.8 is not up to par when compared to the Qualcomm Snapdragon mobile SoC's we find in most recent Samsung smartphones.

However, the difference isn't huge when talking real-life scenarios as Jelly Bean's Project Butter delivers smooth UI navigation even here. App loading times, on the other hand, could be much better.
