ARM Cortex A72 is Getting into Sub $200 Android Smartphones Thanks to Mediatek Helio X20 SoC

Flagship Android smartphones now ship with processors featuring Cortex A72 cores,  or custom variants from Samsung or Qualcomm, and normally cost several hundred dollars. Some new smartphones recently announced with MediaTek Helio X20 deca-core processor lower the price barrier in the $250 to $400 range, but at least two upcoming models will bring the cost below $200: Doogee P7 ($169.99), and Vernee Apollo Lite ($199.99). So let’s see what we’ve got for those prices. Doogee P7 Doogee P7 (preliminary) Specifications: SoC – Mediatek Helio X20 (MT6797) deca-core processor with 2x Cortex A72 cores @ 2.5 GHz, 4x Cortex A53 cores @ 2.0 GHz, and 4x Cortex A53 cores @ 1.4 GHz and ARM Mali-T880MP GPU @ 850 Mhz System Memory – 3GB RAM Storage – 16 GB storage and micro SD slot up to 64GB (shared with dual SIM slot) Display – 5.5″ capacitive touchscreen, 1920×1080 resolution; 160K colors Cellular […]

Amlogic S912 Processor Specifications

Amlogic plans to launch at least three new processors for OTT boxes and set-top boxes this year: Amlogic S905X, Amlogic S912, and Amlogic S905D.  We already knew Amlogic S905 specifications, but I’ve recently received a document with some more details about Amlogic S912 revealing Mali-T820 GPU, a lack of USB 3.0 support, but still some interesting features such as HDMI 2.0a, 4K VP9, 10-bit H.265, Gigabit Ethernet Mac, and so on. Amlogic S912 specifications with highlights in bold showing differences with Amlogic S905X: CPU Sub-system –  Octa core ARM Cortex-A53 CPU up to 2 GHz (DVFS) with two CPU clusters one optimized for high performance (big) and the other for low power (LITTLE) 3D Graphics Processing Unit –ARM Mali-T820MP3 GPU up to 750MHz (DVFS) with 3 shader engines supporting OpenGL ES 1.1/2.03.1, DirectX 11 FL9_3, OpenCL 1.1/1.2 full profile and RenderScript. 2.5D Graphics Processor – Fast bitblt engine with dual […]

PULPino Open Source RISC-V MCU is Designed for IoT and Wearables

lowRISC is not the only open source processor project based on RISC-V instructions, as researchers at ETH Zurich university and the University of Bologna have developed PULPino open-source processor based on RISC-V instructions set, optimized for low power consumption, and targeting wearables and the IoT applications. PULPino is a single core processor derived from the PULP project (Parallel Ultra-Low-Power Platform) featuring a quad core RISC-V SoC with new RI5CY Signal Processing ISA extensions designed by the universities. The core has an IPC (instructions per cycle) close to 1, full support for the base integer instruction set (RV32I), compressed instructions (RV32C) and partial support for the multiplication instruction set extension (RV32M). PULPino also features peripherals such as I2S, I2C, SPI and UART. PULPino has already been taped out as an ASIC in UMC 65nm at the beginning of the year, but the RTL code be run on Xilinx Zynq-7010 powered Zedboard, […]

MK808B Pro Amlogic S905 Android TV Stick Unboxing and Teardown

MK808B Pro TV stick is the successor of the popular MK808B Plus and before that MK808B Android TV dongles with an upgrade to Amlogic S905 processor with 4K support. GeekBuying sent me a sample for evaluation, so I’ll start by checking the hardware before testing the device thoroughly in the full review. MK808B Pro Unboxing I received the stick in a package larger than I expected, but apparently about the same as the previous models (which I had not reviewed). But that’s because of the included accessories: a 5V/2A power supply, a USB cable, a mini USB OTG adapter, a mini HDMI to HDMI cable, and a user’s manual. Apart from the markings “MK808B PRO” and “4K Ultra HD”, the device looks the same as the older models. A mini USB port for power, and a USB 2.0 host port can be found on one end, with a micro SD […]
