Qualcomm Snapdragon 665 vs Mediatek MT6735

Qualcomm Snapdragon 665

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.

Mediatek MT6735

The 1.5 GHz MediaTek MT6735 is a 64-bit ARM-based SoC launched in 2014 primarily for small budget to mainstream Android devices. The quad-core processor is manufactured in 28 nm and is based on the Cortex-A53 architecture. It integrates a cat.4 LTE modem with CDMA2000 and an ARM Mali-720 GPU capable of decoding and encoding videos of up to 1080p30. Compared to the MT6732, the MT6735 utilizes a slower graphics unit.

Processor

The Cortex-A53 is the successor to the popular Cortex-A7 design. In addition to the jump from 32-bit to 64-bit architecture (ARMv8 ISA) to address more than 4 GB of memory, the new design offers better branch prediction and higher performance-to-power ratio that rivals the Cortex-A9. The four cores of the MT6732 are clocked at up to 1.5 GHz and sits roughly in between the Qualcomm Snapdragon 610 (4x Cortex-A53 at 1.7 GHz) and Snapdragon 410 (4x Cortex-A53 at 1.2 to 1.4 GHz). The power-efficient processor is fit for common tasks like browsing and running light applications.

Graphics

The integrated single-core Mali-T720 is an entry-level GPU clocked at up to 600 MHz (450 MHz likely). Most Android games will play at acceptable frame rates on medium resolutions and quality.

Features

The MT6732 SoC integrates a memory controller (32-bit LPDDR3, 6.4 GB/s), multiple radios (WLAN, Bluetooth, GPS), and a cellular modem (GSM, UMTS, GPRS, HSPA+, HSUPA, TD-SCDMA, EVDO, and LTE Cat 4). Its integrated video engine allows for 1080p playback at 30 FPS. Cameras are supported up to 13 MP.
