Qualcomm Snapdragon 835 (8998) vs Qualcomm Snapdragon 670
Qualcomm Snapdragon 835 (8998)
► remove from comparison
The Qualcomm Snapdragon 835 Mobile Platform (MSM8998) is a high-end SoC for smartphones (mostly Android based) that was released early 2017. Its one of the first processors that is manufactured in 10 nm (LPE FinFET at Samsung). The SD835 is the successor to the Snapdragon 821.
It integrates 4x Kryo 280 at 2.45 GHz (max) for performance and 4x Kryo 280 at 1.9 GHz (max) for efficiency. Furthermore offers an X16 LTE modem, 802.11a/b/g/n/ac/ad WiFi, a dual-channel 32-Bit 1866 MHz LPDDR4x memory controller, an UFS 2.1 controller, Hexagon 682 DSP, Spectra 180 Image Seonsor Prozessor, Bluetooth 5.0, GPS, GLONASS, Baeidou, Galileo Satellite Support.
Qualcomm Snapdragon 670
► remove from comparison
The Qualcomm Snapdragon 670 (SD670) is a fast mid-range ARM-based SoC largely found on Android tablets and smartphones. Announced late 2018, the SD670 is the successor to the Snapdragon 660. It features 8 Kryo 360 cores (custom design, 64-Bit capable) that are divided in two clusters. A fast cluster of two cores with up to 2 GHz and a power saving efficiency cluster with up to 1.7 GHz. Both clusters can also used together.
In addition to the 8 CPU cores, the SoC integrates a mid range Adreno 616 GPU with a LPDDR4X-3733 memory controller (dual-channel 1867 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 the Snapdragon 670 is slightly faster than the old Snapdragon 660 and therefore a solid mid-range processor.
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 10 nm LPP process at Samsung, the energy efficiency has been improved noticeably compared to its 14 nm predecessors.
