Qualcomm Snapdragon 675 vs Qualcomm Snapdragon 660 vs Qualcomm Snapdragon 636

Qualcomm Snapdragon 675

► remove from comparison Qualcomm SD 675

The Qualcomm Snapdragon 675 (SD675) is a fast mid-range ARM-based SoC largely found on Android tablets and smartphones. It features 8 Kryo 460 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-A76 design. And a power saving efficiency cluster with up to 1.6 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 612 GPU, a X12 LTE Modem with up to 600 Mbps download (Cat 12) and 150 Mbps upload (Cat 13), a 802.11ac (Wifi 5) Wave 2 WLAN modem (up to 867 Mbps), a Bluetooth 5.0 radio, satellite positioning (GPS, QZSS, GLONASS, SBAS, Beidou and Galileo) and a video engine (up to 4k30 encoding and support for H.265, H.264, VP8 and VP9).

Performance

Thanks to the two fast Cortex-A76 based cores, the SD675 is able to even best the old high end Snapdragon 835 SoC in some benchmarks. The less powerful Snapdragon 670 e.g. only achieves 70 to 77% of the performance in Geekbench 4.3 (single - multi core test). Current high-end SoCs like the Snapdragon 855 however can still add 50-70% on top of the performance of the 675.

The Snapdragon 675 is produced in the new 11nm LPP (Low Power Plus) process at Samsung which is a combination of 14nm and 10nm. Compared to 14nm LPP, the 11nm LPP process should be able to increase performance by 15% and decrease the chip size by 10% according to Samsung.

Qualcomm Snapdragon 660

► remove from comparison Qualcomm SD 660

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.

Qualcomm Snapdragon 636

► remove from comparison Qualcomm SD 636

The Qualcomm Snapdragon 636 (SDM636) is a mid-range octa-core SoC with eight custom Kryo 260 cores at up to 1.8 GHz, an Adreno 509 GPU, a LPDDR4-2666 memory controller (1333 MHz) and a X12 LTE (Cat 12/13, 300 Mbps down, 150 Mbps up) modem. Furthermore, the chip supports 802.11ac WiFi and Bluetooth 5.0. It is manufactured in 14nm FinFet. Qualcomm states a 40% faster performance compared to the old Snapdragon 630 (8x ARM Cortex-A53).
