The mid-range Snapdragon 660 processor comes surprisingly close to top-end Snapdragon 835 chip in performance test26
In GeekBench (a prominent CPU performance test), the Snapdragon 660 – as present inside an unidentified smartphone code-named Heart – racked up 5,455 points in the multi-core test. Compared to the flagship Snapdragon 835 as present in the Samsung Galaxy S8+'s score – 6,301 points – that's a 15.5% difference. Not bad for a chip that's meant to power devices several times cheaper than Samsung's finest!
At the same time, the Snapdragon 660 is 16% more powerful than its predecessor, the Snapdragon 653 (as tested inside the Oppo F3 Plus smartphone). The latter acquired a score of 4,695 in the same test.
The lines between mid-range and high-end hardware become increasingly blurredSingle-core tests are less relevant, as the bulk of smartphone processing is a multi-core affair. But they are still available and read as follows: 1,588 for the Snapdragon 660, 1,832 points for the Snapdragon 835, and 1,438 points for the Snapdragon 653. The new processor enjoys a small bump over the older model, and keeps up not too far behind the flagship 835.
The Snapdragon 660 is built on a reasonably up-to-date 14nm production process, although Qualcomm and Samsung's high-end chipsets make use of a newer 10nm process. This makes them smaller and more power-efficient relative to their higher performance. The processor has eight 64-bit "Kryo 260" CPU cores with 2.2Ghz maximum speed, with the Adreno 512 graphics unit handling visuals. The processor supports high-end features, such as 4K video capture and playback, quick charging, the latest standards for Wi-Fi and Bluetooth connectivity, and LTE Category 13 uplink (150Mbps) / Cat 12 downlink (600Mbps) internet.
