In the hardware department, the Nokia 7.2 ship with an octa-core Qualcomm Snapdragon 660 CPU. This was same CPU used in the older Nokia 7 Plus. It an 8-core 14nm architecture comprising of 4×2.2 GHz Kryo 260 based on Cortex-A73, and 4×1.8 GHz Kryo 260 based on ARM Cortex-A53, pegged with Adreno 512 GPU, 4/6 GB RAM and either 64/128 GB internal storage( our unit is 6GB RAM and 128GB storage).
The SD660 is almost 2 years older now, but since it is what HMD Globale decided to use on the 7.2, let see how it fairs against few smart phones out there, either within same price range, running same or similar CPU, or targeted at same market segment.
Our performance testing began with Antutu, which analyze the overall performance of the smartphone compared with other devices. Surprised that our Nokia 7.2 made it above 150,000 mark? Well, it got a huge advantage from it 6GB RAM, which is why it was able to score above devices with same CPU, but smaller RAM size, like the Xiaomi Redmi Note 7. The 4GB RAM version was only able to make it a little above 139,000 in other reviewers testing.
GeekBench is giving fair advantage to the Mediatek Helio G90T present in the Redmi Note 8 Pro. This is so because the bench-marking app emphases is on raw CPU power. The Nokia 7.2 stands just between the Redmi Note 7 with same CPU and the Huawei P30 Lite, although with a very close tie with the two devices below it, while the Tecno Phantom 9 guards the basement.
When all processors were fired, the 7.2 got pushed down to the Phantom 9. It even got a score lower than the Redmi Note 7 which has same CPU. There are few factors that could be responsible for these, for example, number of apps running in the background when the test was run.
Real Life Hardware Performance
In real life usage, the device is fairly fast through my day to day use. While I must admit a few hooks and stutters at intervals, there were not annoying, and chance are, you may not even notice it especially if your app installs are minimal. Nevertheless, the OS optimization of Android One also has a lot to do here, and your experience of Snapdragon 660 may be entirely different with smart phone with a poorly optimized OS and UI.
It mostly normal for a glassy smartphone to warm up a bit during use. The 7.2 of course do warm up, and the temperature even tends to be more noticeable during stressful moment, especially around the camera ring area.
