Mediatek Helio A20 MT6761D vs Qualcomm Snapdragon 617 MSM8952
Mediatek Helio A20 MT6761D
► remove from comparisonThe Mediatek Helio A20 MT6761D is an entry-level ARM SoC for smartphones and tablets (mainly Android-based) that was introduced in 2020. It integrates four ARM Cortex-A53 cores clocked at up to 1.8 GHz. It integrates a PowerVR GE6300 GPU clocked at up to 550 MHz. The integrated memory controller supports LPDDR4x (max. 4 GB at 1200 MHz). Furthermore, a LTE radio with Cat-4 DL (150 Mbps download) and Cat-6 UL (50 Mbps upload) and a 802.11 a/b/g/n/ac Wi-Fi 5 modem is integrated.
Compared to the similar named A22 MT6761, the MT6761D offers lower clocked CPU and GPU cores and a slower LTE modem, but is produced in the modern 12 versus 16nm process.
Qualcomm Snapdragon 617 MSM8952
► remove from comparisonThe Qualcomm Snapdragon 617 MSM8952 is a mid-range ARMv8-based SoC largely for Android tablets and smartphones announced in September 2015. In addition to 8 Cortex-A53 CPU cores at up to 1.5 / 1.2 (performance and power saving cluster) GHz, the SoC integrates an Adreno 405 GPU with a LPDDR3-1866 memory controller and supports Wi-Fi (802.11ac), Bluetooth 4.0, UMTS, and LTE. Compared to the older Snapdragon 615, the clock speeds are a bit lower (hits 1.7 GHz max).
CPU
The Cortex-A53 is the successor to the very popular Cortex-A7 design. In addition to the new 64-bit capable ARMv8 ISA, the cores offer a variety of other improvements such as better branch prediction. This leads to a significantly higher performance per clock, which is even above the older Cortex-A9.
The eight cores of the Snapdragon 617 are divided into two quad-core clusters, each optimized for a different operating point. While one cluster can clock up to 1.5 GHz to handle more demanding applications, the other cluster is limited to a maximum of 1.2 GHz for energy-saving purposes. All eight cores can be active at the same time, although most applications aren't parallelized to support 8 cores efficiently.
Overall, the Snapdragon 617 offers a performance similar to that of the older Snapdragon 600 (Krait architecture).
GPU
Another new feature is the integrated graphics unit named Adreno 405 (most likely around 550 MHz). The Adreno 400 series has been substantially redesigned and supports DirectX 11.2 (FL 11_1) including hardware tessellation, OpenGL ES 3.1, and OpenCL 1.2. Furthermore, the performance has been significantly improved, which is now similar to the Adreno 320 and PowerVR G6200.
Features
The Snapdragon 617 offers numerous wireless technologies such as Bluetooth 4.0 and WLAN 802.11a/b/g/n/ac as well as a Multi-SIM cellular modem supporting LTE cat. 4 (up to 150 Mbps), WCDMA, CDMA, EV-DO, TD-SCDMA and GSM/EDGE.
The SoC can encode and decode 1080p videos using dedicated hardware and stream content to displays with up to 2560 x 2048 pixels. A large number of video codecs including H.265 (playback only) will be supported. The camera ISP can handle sensors with up to 21 MP.
Power Consumption
The Snapdragon 617 is manufactured by TSMC in a 28 nm LP process. According to the specifications, we expect a medium or medium-high power consumption for use in medium-sized or larger smartphones and tablets.
