Oppo R7 review: Changing course

GSMArena team, 03 July 2015.

Synthetic benchmarks

The Oppo R7 is equipped with a Snapdragon 615 chipset, a solution so popular, that Oppo itself has no less than 4 smartphones in its lineup, powered by Qualcomm's upper midrange chip.

Oppo likes to tinker with processor clock speed to adjust it to the specific device, and it's no different on the R7. The four "powerful" Cortex-A53 cores in the pseudo-big.LITTLE setup can go as high as 1.46GHz, while the other four are limited to 1.11GHz. Qualcomm quotes typical figures of 1.7GHz and 1.0GHz, respectively.

The R7 comes with a spacious 3GB of RAM, so multitasking should be a breeze. It's among the key improvements over the R5, and makes the R7 only the second Oppo smartphone with that amount after the now aging flagship Find 7.

We kick off the benchmark routine with Geekbench 3, which measures solely CPU performance. The R7 sits midway between the S615 equipped R5 and R1x. The R7 is also no match for last year's flagships, but is also bested by the Samsung Galaxy A7 (S615, again), which puts up a better fight.

Antutu has become more or less an industry standard for a quick overall benchmark and measures RAM and storage performance on top of CPU power. The Oppo R7 is trailing behind the S615 competition, and would have been last, if it weren't for the ZTE Blade S6, but that one is a little over half the R7's asking price.

In all fairness, the S615 crowd is pretty tightly spaced, and is lagging behind the 2014 top-end Snapdragon 801. The Mediatek MT6595 inside the Meizu MX4 and Lenovo Vibe X2 is the undisputed champ here.

Another compound benchmark, Basemark OS II 2.0 paint a more favorable picture of the R7. It still trails behind the Sony M4 Aqua and the Galaxy A7, but leaves a few of the S615 competitors behind in the overall score. The the single- and multi-core CPU tests mostly mirror the results.

The Snapdragon 615 comes bundled with an Adreno 405 GPU, which typically does a good job as long as you don't sweat it with the latest 3D games.

In Basemark X it clearly pulls ahead of all competitors with the same chipset. The Xperia M4 Aqua comes closest, followed by the Blade S6, while the Oppo R1x is a mile back, indicating a different setup there.

In the lighter T-Rex routine of GFXBench the R7 manages the same 15fps both onscreen and off, which shouldn't be a surprise, as both tests are carried out at 1080p resolution. The R1x, Blade S6 and Xperia M4 Aqua all pull ahead in the onscreen test, but they're favored by their 720p displays, which have a lot less pixels to render.

The more demanding Manhattan test introduces an expected overall hit in frame rates. In the offscreen test the differences between the S615 packing smartphones are negligible, save for the trailing R1x. The onscreen test widens the gap between HD and FullHD displays, but the R7 still does an OK job, given its hardware.

The Oppo R7 comes with a pair of browsers installed. We tested both and when it comes to JavaScrip, Kraken 1.1 says that neither is impressive, but Chrome is marginally faster than Oppo's browser.

Not so in Browsermark 2.1, where Chrome posted solid scores upwards of 1400, while the proprietary app was nowhere to be found, with numbers around 600. We therefore concluded that Chrome is the only logical choice and posted its results below.

Altogether, the Oppo R7 is an average performer, given its internals. It is admittedly better optimized than the R1x, with Color OS 2.1 likely responsible. However, the 3GB of RAM fail to show any meaningful advantage in benchmarks, and the R7 is consistently outperformed by 2GB models.
