Qualcomm Snapdragon 630 vs Qualcomm Snapdragon 662 vs Qualcomm Snapdragon 439

Qualcomm Snapdragon 630

The Qualcomm Snapdragon 630 (SDM630) is a mid-range octa-core SoC with eight ARM Cortex-A53 CPU cores at up to 2.2 GHz, an Adreno 508 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. The processor performance should similar to the older Snapdragon 626 which offers similar clock speeds. Compared to the 626, the 630 however supports faster memory and offers faster LTE, Wifi and Bluetooth standards.

Qualcomm Snapdragon 662

The Qualcomm Snapdragon 662 is a lower mid-range ARM-based SoC largely found in 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.

Qualcomm Snapdragon 439

The Qualcomm Snapdragon 439 (SD439) is a lower mainstream SoC for (Android based) smartphones and tablets. Compared to the older Snapdragon 435, the 439 is now manufactured in the current 12nm FinFET process and offers higher clock speeds of 2 GHz of the eight ARM Cortex-A53 cores (compared to 1.4 GHz). Wifi (now ac Wave 2 / Wifi 5) and Bluetooth (v5) were also updated, however the GPU still is the rather slow Adreno 505 and the LTE modem was even downgraded to a X6 with only Cat. 4/5 (max. 150 Mbps download, 75 Mbps upload).

Thanks to the higher maximum clock speed, the performance of the Snapdragon 439 mobile platform can reach the old Snapdragon 625 (also 2 GHz with 8x Cortex-A53). However, there is still a big gap to the SoCs with bigger performance cores.
