Sony Xperia C5 Ultra review

Performance

The Sony Xperia C5 Ultra is powered by the Mediatek MT6752 SoC - the same one ticking inside the Xperia C4. It pack eight Cortex-A53 CPU cores clocked at 1.7GHz and capable of working simultaneously.

The octa-core processor is coupled with a Mali-T760MP2 GPU and 2GB of RAM, and since those handle 1080p apps, the C5 Ultra should offer the same synthetic performance as the previous C4 model.

The battery of tests starts as usual with Geekbench 3.0, which measures RAW CPU performance. Mediatek's True octa-core concept is a real beast and C5 Ultra posts a beastly score - the same as its C4 predecessor, but unmatched among its rivals in the midrange.

The popular Antutu benchmark has become an industry standard for overall performance, and it evaluates CPU, graphics, memory and storage, the lot. Another great performance here, the Xperia C5 Ultra smokes the S615-powered Oppo R7 Plus and is on par with the S810-equipped LG G Flex2. Its GPU isn't shining, but it compensates with its powerful processor.

The Xperia C5 Ultra fails to impress in Basemark OS II 2.0, but does as much as a Snapdragon 615 device would do (Galaxy A8, Oppo R7 Plus).

Single core-performance is led by the Snapdragon 801s, though they rely on an entirely different quad-core architecture and thus obviously pack more punch per core.

Unsurprisingly, the Xperia C5 Ultra and its C4 sibling lead the way in the multi-core test, with S615 Oppo R7 Plus a mile behind, and noticeably faster than the top-dog Snapdragon 810.

Graphics performance is less exciting but mostly adequate for the mid-range class. The results are not what they initially appear though, as the top spots are occupied mostly by the 2014/2015 flagships, which benefit from their superior GPUs.

Moving on to browser benchmarks, things don't look all that well for the Xperia C5 Ultra. Even though it's running nothing but Chrome, thus supposedly avoiding blunders by the manufacturer's software engineers, the C5 Ultra is consistently trailing, both in the JavaScript-focused Kraken 1.1 and the broader BrowserMark 2.1.

All in all, the Sony Xperia C5 Ultra proves to be a capable performer, with strong results in processor benchmarks and average graphics for its class. It does have its weak spot, and that's browser performance, though.
