Rockchip RK3168 vs MediaTek Helio X27 MT6797X vs Loongson 2F 900MHz
Rockchip RK3168► remove
The Rockchip RK3168 is a low-end ARM SoC designed primarily for smartphones. It integrates two Cortex-A9 CPU cores with NEON extension, a PowerVR SGX 540 graphics card (400 MHz) and a memory controller for low-power (LP-) DDR2/DDR3. The performance should be comparable to other similarly clocked Cortex-A9 SoCs such as the Samsung Exynos 4210. Thanks to its 28nm manufacturing, the RK3168 is relatively power efficient and should enable longer battery life.
MediaTek Helio X27 MT6797X► remove
The Mediatek Helio X27 MT6797X is an upper mainstream ARM SoC for smartphones (mainly Android based). It is manufactured in a 20 nm process and is equipped with 10 CPU cores. Two fast Cortex-A72 cores are running at up to 2.6 GHz (performance), four Cortex-A53 cores at up to 2 GHz (balanced) and four Cortex-A53 cores at up to 1.6 GHz (efficiency). All cores support 64-bit and the utilization of three clusters is supposed to improve efficiency according to Mediatek. The two A72 cores are only designed for short "Burst-Performance scenarios" according to Mediatek and are probably not used for sustained workloads. Compared to the similar named MT6797, the MT6797X was introduced later and offers higher clock speeds for CPU and GPU.
The chip also includes an LTE modem (Cat. 6 300/50 Mbps, DC-HSPA+, TD-SCDMA, EDGE, CDMA2000, ...) as well as a WLAN 802.11ac (280 Mbps) modem. GPS/Glonass/BeiDou is supported for location. The integrated video encoder can handle up to 4Kx2K H.265 at 30 fps and HDR. The SoC can also decode H.265, H.264 and VP9 in 4K30.
The processor is manufactured in a 20 nm process at TSMC and should have an average power consumption under load.
