The Qualcomm Snapdragon 665 (SM6125) is a fast mid-range ARM-based SoC largely found on Android tablets and smartphones. It features 8 Kryo 260 cores (custom design, 64-Bit capable) that are divided in two clusters. A fast cluster of four cores with up to 2 GHz (Kryo 260 Gold - Cortex-A73 derivate) and a power saving efficiency cluster with up to 1.8 GHz (Kryo 260 Silver - Cortex A53 derivate). Both clusters can also be used together.
In addition to the 8 CPU cores, the SoC integrates a mid range Adreno 610 GPU with a LPDDR4 memory controller (dual-channel) and supports Wi-Fi (802.11ac + MIMO, max. 867 Mbps), Bluetooth 5, and LTE (X12 LTE modem with up to 600 Mbps download and 150 Mbps upload).
Power Consumption
Thanks to the new 11 nm LPP process, the energy efficiency should be quite good.
The Qualcomm Snapdragon 690 5G (SD690) is a fast mid-range ARM-based SoC largely found on Android tablets and smartphones. It features 8 Kryo 560 called cores (64-Bit capable) that are divided in two clusters. A fast cluster of two cores with up to 2 GHz and based on the ARM Cortex-A77 design. And a power saving efficiency cluster with up to 1.7 GHz and based on much smaller ARM Cortex-A55 cores. Both clusters can also used together.
In addition to the 8 CPU cores, the SoC integrates a lower mid range Adreno 619L GPU, a X51 5G radio (up to 2.5 Gbits download, no mmWave), a 802.11ax (Wi-Fi 6, 8x8 sounding, WPA3, Dual Band, 2x2), a Bluetooth 5.1 radio, satellite positioning (GPS, QZSS, GLONASS, SBAS, Beidou and Galileo) and a video engine (support for H.265, H.264, VP8 and VP9).
Performance
Due to the two big A77 cores, the performance of the SoC in our benchmarks is on par with mid range SoCs like the Snapdragon 765 or the Dimensity 800U.
The Snapdragon 690 is produced in the 8nm LPP (Low Power Plus) process at Samsung.
The Qualcomm Snapdragon 660 (SD660) is a fast mid-range ARM-based SoC largely found on Android tablets and smartphones. Announced in mid 2017, the SD660 is the successor to the Snapdragon 625. It features 8 Kryo 260 cores (custom design, 64-Bit capable) that are divided in two clusters. A fast cluster of four cores with up to 2.2 GHz and a power saving efficiency cluster with up to 1.8 GHz. Both clusters can also used together.
In addition to the 8 CPU cores, the SoC integrates a mid range Adreno 512 GPU with a LPDDR4 memory controller (dual-channel 1866 MHz) and supports Wi-Fi (802.11ac + MIMO, max. 867 Mbps), Bluetooth 5, and LTE (X12 LTE modem with up to 600 Mbps download and 150 Mbps upload).
Performance
In Benchmarks of the Oppo R11, the CPU part of the Snapdragon SD660 performs between former high end Socs like the Snapdragon 821 in the Pixel XL and the Snapdragon 835. The graphics performance is however much lower, as the Adreno 512 is only a slight upgrade of the older Adreno 510 (due to the higher clock speed).
CPU
The Snapdragon 660 is based on a similar concept as ARM's big.LITTLE, which combines a low power CPU cluster (2x Kyro clocked at up to 1.8 GHz) and a performance CPU cluster (2x Kyro clocked at up to 2.2 GHz). The clock speed of each cluster can be individually adjusted (but not per core) and the lowest clock speed is 310 MHz (unverified).
Power Consumption
Thanks to the new 14 nm process, the energy efficiency has been improved noticeably compared to its 20 nm predecessors.
