This is certainly a more novel approach to big.LITTLE, but MediaTek states that this type of design lends itself to a 30 percent improvement in power consumption compared with a similar 2-cluster design. The idea is to scale even more effectively from small low power cores, through a quad-core mid-stage and right on up to a dual-core high performance configuration. The design makes use of heterogeneous processing, meaning that tasks can be dynamically allocated to any CPU core at any time. MediaTek uses its custom designed CorePilot as the task scheduler, which is designed around optimum power allocation.
The CPU is paired with dual channel 32-bit LPDDR3 memory interface, which runs at 933MHz. Although slower than the new LPDDR4 implementations found in the likes of the Exynos 7420 or Snapdragon 810, the X20’s RAM should be more than enough for standard 1080p devices and should run fine up to the maximum supported QHD display resolution.
ARM processing technology runs right through the SoC, as there’s a Mali-T880 MP4 GPU and integrated Cortex-M4 companion core used for various audio processing tasks, which supports specific DSP instruction and has an FPU. The low power Cortex-M4 handles audio decode, speech enhancement and voice recognition, even when the screen is off, to save on battery life.
As for the GPU, the X20 is believed to be the first chip to make use of ARM’s latest Mali-T880 graphics technology, although this is the only detail left unconfirmed. The SoC makes use of four shader cores for a mid-range performance target, and is clocked at 700MHz. For comparison, Samsung’s high-end Exynos 7420 makes use of an eight shader core Mali-T760, but the X20 should still offer performance in the area of last generation flagships. There has also likely been some compromise here on the amount of silicon space available after the number of CPU cores and also the thermal limit of the chip.
The X20 SoC packs in a number of other features that you would expect from a high-end mobile chip. Including, 2160p30 10-bit H.264/HEVC/VP9 decode, 2160p30 HEVC w/HDR encode, support for a single image processor up to 32MP or dual 13MP cameras, MediaTek’s CDMA2000 compatible integrated modem and Category 6 LTE speeds of 300Mbps download and 50 Mbps upload.
