Oppo R1x review: Sleek geometry

Synthetic benchmarks

The Oppo R1x is powered by the popular upper-midrange Snapdragon 615 chipset. It relies on an octa-core processor in a big.LITTLE configuration of sorts with a quad-core Cortex-A53 cluster clocked at 1.34GHz and another quad-core Cortex-A53, ticking at 0.8GHz. The numbers mean it's slightly underclocked compared to the typical 1.7GHz/1.0GHz clock rates found in other smartphones, equipped with the S615 SoC.

The benchmark results largely reflect that, though some scores do come out rather surprising, knowing the differences in clock rate. The CPU-centric Geekbench, for example puts the R1x in the middle of the S615 crowd, with Oppo's own R5 significantly ahead, but still beating the Sony Xperia M4 Aqua and trumping the ZTE Blade S6.

In the compound Antutu benchmark the R1x is again an average performer, outplaying the Blade S6 and the HTC Desire 820, but behind the Xperia M4 Aqua. In both tests, the Oppo smartphone lags behind representatives of competing platform in the face of Mediatek-powered Lenovo Vibe X2 and Acer Liquid Jade S, and the Huawei Honor 6, driven by an in-house Kirin 920. What becomes obvious is the clear advantage over the lesser Snapdragon 410 in the Samsung Galaxy A5 and E7.

In the next all-round benchmark Basemark OS II 2.0 the Oppo R1x scores consistently with the majority, if marginally ahead, but is nonetheless significantly behind the M4 Aqua. The CPU sections of the benchmark place the R1x lower in the charts.

Graphics department has the Adreno 405 taking care of things and it's clocked at 550MHz. Basemark X places the R1x last among the S615-powered devices, with all other one posting 20%-25% better numbers. Little consolation can be found in the fact that the R1x inches ahead of the Acer Liquid Jade S with Mali-T760MP2 GPU.

In GFXBench 3.0 the Oppo R1x continues its unimpressive run, again placing last in the off-screen tests, significant margin behind all devices with the same SoC, which score otherwise very similar results.

The on-screen figures are more relevant to real-life performance, but the R1x fails to impress here either. The Desire 820 snatches the top position in the T-Rex routine followed closely by the Xperia M4 Aqua. The R1x manages about 20fps, which is the worst result among the S615 devices with 720p screens.

The Xperia M4 Aqua proves the smartphone to beat in the more intense Manhattan test and the R1x strengthens its last position among 720p Snapdragon 615 handsets.

Browser performance is another area where the R1x underdelivers. It's score in the Browsermark 2.1 HTML5 and CSS benchmark is so low, that even the Snapdragon 410 devices beat it by a mile. The JavaScript-focused Kraken 1.1 results in an average score, and one that's finally ahead of the Xperia M4 Aqua.

Overall, the Oppo R1x doesn't deliver the results expected from the hardware inside. It likely has something to do with the low CPU clock speeds and the inclination towards battery autonomy instead of top-of-the-class performance. That said, the phone handles daily tasks with ease and there's no lag while browsing the interface or surfing the web.
