Mediatek Helio P10 MT6755 vs Qualcomm Snapdragon 801 MSM8974AB vs Mediatek MT8732

Mediatek Helio P10 MT6755

The Mediatek Helio P10 MT6755 is a mid-range ARM SoC for smartphones and tablets that was available starting in Q3 2015. The octa-core processor includes eight 64 Bit Cortex-A53 cores clocked with up to 2 GHz. Furthermore a ARM Mali-T860 MP2 graphics card with up to 700 MHz and a LTE Cat. 6 modem is integrated.

The performance of the CPU cores si similar to the Kirin 930 and therefore in the mid-range of smartphone SoCs in 2015 and 2016.

The SoC is manufactured at TSMC in 28nm (HPC+) and also suited for smartphones (e.g. the Elephone P9000).

Qualcomm Snapdragon 801 MSM8974AB

The Qualcomm Snapdragon 801 MSM8974AB is an ARM-based SoC for tablets and smartphones. It is built at TSMC in a 28nm HPM (High Performance Mobile) HKMG process, whereas the Snapdragon 600 was manufactured in 28nm LP. In addition to 4 CPU cores with a clock speed of up to 2.36 GHz, the chip also integrates an Adreno 330 GPU up to 578 MHz, an LPDDR3-1866 memory controller and various radio modules (UMTS/LTE, WiFi, Bluetooth, GPS). The slightly higher CPU/GPU clocks and faster memory support are the key differences to the Snapdragon 800 MSM8974.

Processor 

The CPU portion is based on Qualcomm's Krait architecture, which is compatible with the ARMv7 ISA. Compared to the Snapdragon 600 (Krait 300), the new Krait 400 cores of the Snapdragon 800/801 have been tweaked just slightly with faster L2 cache. Thanks to a clock rate of up to 2.36 GHz and a high performance per MHz somewhere between an ARM Cortex-A9 and a Cortex-A15, the Snapdragon 801 offers very strong CPU performance. The S801 competes with the Nvidia Tegra 4, Samsung Exynos 5420 and Apple A7 and is therefore one of the fastest ARM SoCs on the market as of 2013.

Graphics

Another difference between the Snapdragon 600 and 800/801 is the graphics unit. While the S600 implements an Adreno 320 (400 to 450 MHz), the S800 /S801 feature the faster Adreno 330 (MSM8974AB: 578 MHz). Both GPUs offer the same amount of texture units (8 TMUs), but the Adreno 330 has 50 percent more shaders (probably 6x SIMD16 vs. 4x SIMD16 of the previous generation). In conjunction with the higher memory bandwidth, the performance is significantly better. As a result, the Adreno 330 is slightly faster than the Mali-T628 (Exynos 5420) and the PowerVR G6430 (Apple A7). Depending on the device and cooling, however, the performance may vary. The GPU supports OpenGL ES 3.0 as well as OpenCL 1.2.

Features 

Furthermore, the MSM8974AB supports many wireless technologies: Bluetooth 4.0, WLAN, IEEE 802.11a/b/g/n/ac (2.4/5 GHz), GSM (GPRS, EDGE), W-CDMA/UMTS (HSDPA, HSUPA, HSPA+, cat.29 DC-HSPA+), MBMS, cat.4 LTE, CDMA2000 (1X RTT, 1 × EV-DO Rel.0/Rev.A/Rev.B, 1× EV-DO Rev.A MC, 1× Adv Rev.A/Rev.B) and TD-SCDMA. 

The MSM8974AB can encode and play UHD 4K videos in 3840x2160 at 30 FPS (120 Mbps H.264 High Profile) simultaneously via dedicated hardware. Moreover, it supports both USB 2.0 and 3.0 and cameras up to 55 megapixels and stereoscopic 3D.

Power Consumption

Thanks to the new 28nm HPM HKMG process, the energy efficiency has been improved significantly compared to its LP 28nm S600 predecessor. Depending on the field of application, the maximum power consumption should be about 3 W for smartphones or 4 W or greater for tablets. This should be similar to comparable ARM SoCs currently in the market. However, the MSM8974AB will likely to need a little more power than the slightly lower clocked MSM8974.

Mediatek MT8732

he Mediatek MT8732 is a mid range ARM based SoC for (mostly Android based) smartphones. It was manufactured in 28nm and offers a quad-core processor with four ARM Cortex-A53 cores clocked at up to 1.5 GHz. As a graphics card, the SoC integrates a ARM MAli-T760MP2. The integrated LTE radio supports LTE Cat. 4 and a WiFi modem is also included.
