Khadas VIM4 single board computer was first unveiled last October with Amlogic A311D2 octa-core Cortex-A73/A53 processor, 8GB LPDDR4X, but it’s only been launched today, and you can now buy the Khadas VIM4 board for right under $200. It is an upgrade to Khadas VIM3 Pro launched with Amlogiv A311D hexa-core processor a few years ago, and our testing in Android 11 revealed the main benefit may be the upgrade GPU that delivered a 67% boost in 3DMark, but CPU multi-core performance and memory bandwidth will also see some benefits over Amlogic A311D, even against in overclocked systems like ODROID N2+. Here’s a reminder of Khadas VIM4 specifications: SoC – Amlogic A311D2 octa-core processor with 4x Arm Cortex-A73 cores @ up to 2.2 GHz and 4x Cortex A53 cores @ up to 2.0 GHz, Arm Mali-G52 MP(8EE) GPU, (Note: no NPU at this time) System Memory – 8GB LPDDR4X @ 2016 […]
Khadas VIM4 Review – Part 2: Android 11 preview and benchmarks
In the first part of Khadas VIM4 review, I showed off the Amlogic A311D2 SBC and some accessories such as the DIY case and M2X expansion board to add M.2 SSD and modem and tried out OOWOW cloud services to install Ubuntu 20.04 server. I’ve now just gotten Fiber Internet at home, so it’s much more practical to test the system, and in the second part of the review, I’ve installed Android 11 on the VIM4 board, checked out settings and system info, and ran some benchmarks. It will be more like a preview since Android 11 is not a consumer-friendly system at this time, and is more designed for people wanting to build their own applications. Installing Android 11 on Khadas VIM4 with OOWOW system Last time around, I used OOWOW system install in the SPI flash on the board to download and install Ubuntu 20.04 server to the […]
ROCK Pi 4 Model C+ SBC features 1.5 GHz Rockchip RK3399-T CPU, dual HDMI output
ROCK Pi 4 Model C+ is a single board computer (SBC) by a Rockchip RK3399-T hexa-core processor @ 1.5 GHz, equipped with 4GB RAM, and two micro HDMI ports to drive up to one 4K display, and one 2K display. It is yet another ROCK Pi 4 SBC from Radxa, and the first to use the down-clocked RK3399-T processor with other models based on Rockchip OP1 processor clocked at 2.0GHz (overclockable to 2.2/2.4GHz) or the traditional Rockchip RK3399 @ 1.8 GHz (overclockable to 2.0 GHz), and also the first of the family to offer dual HDMI output. ROCK Pi 4 Model C+ specifications: SoC – Rockchip RK3399-T big.LITTLE hexa-core processor with 2x Arm Cortex-A72 @ up to 1.5 GHz (up to 2.0 GHz overclock) 4x Cortex-A53 @ up to 1.4 GHz (up to 1.6 GHz overclock). Note the processor datasheet says the Cortex-A53 cores are limited to 1.0 GHz, but […]
Android RISC-V progress update, emulator support, and roadmap to 2023
We’ve first covered Alibaba T-Head work on Android 10 for RISC-V in January 2021, and later that year they started selling the T-Head RVB-ICE dual-core RISC-V board with GPU for software development. The company has now provided an update for Android 12 RISC-V port, instructions to build Android RISC-V to run it in an emulator, as well as a 2022-2023 roadmap. Alibaba T-head is working on hardware platforms, which appears to be similar to T-Head RVB-ICE board, with the following minimal specifications: CPU – At least Dual-core XuanTie C910 (rv64imafdcv) processor GPU – Compatible with OpenGL ES and OpenCL VPU – HW Video/Picture codec Neural Network Accelerator System Memory – 4GB or more DDR Memory Display – MIPI/HDMI Audio – Multi-Channel Audio output & input Camera – ISP with support for multiple MIPI CSI lanes USB interface(s) They built upon the work done on Android 10 to add support for […]
Ultenic T10 review – A self-emptying 2-in-1 smart vacuum robot with mopping function
Ultenic T10 is a 2-in-1 smart vacuum cleaner and mopping system with a self-emptying base that’s quite similar to the Cybovac S31 robot I reviewed a little over a year ago. The Cybovac vacuum cleaner still works fine, but it has some shortcomings, so when Ultenic asked me whether I would be interested in reviewing their T10 unit, I accepted, and here I am with a new smart robot vacuum cleaner that I’ll review with the Android app in a larger house. Ultenic T10 unboxing The package and hardware are very similar to what I got with the Cybovac model. The robot comes with a charging base that’s pretty large since it includes its own dust bag for the self-emptying function. Key features listed for the T10 vacuum cleaner: Navigation Type – LDS laser for visual SLAM function Suction power Carpet pressurization – 2700 Pa Fixed-point cleaning – 2700 Pa […]
Khadas VIM4 Review – Part 1: Unboxing, kit assembly, and first boot with OOWOW
Khadas VIM4 is a compact Amlogic A311D2 octa-core Cortex-A73/A53 SBC with 8GB RAM, HDMI input and output, WiFI 6 connectivity, and more. You can check our earlier post for the full specifications. The good news is that it will officially launch on May 10. I’ve also just received a Khadas VIM4 review sample today together with accessories. Today, I’ll start by checking out the board, assembling the kit, and trying out OOWOW services to boot OS from the cloud, before testing available operating systems in more detail in the second part of Khadas VIM4 review a little later. Khadas VIM4 kit unboxing I received everything in a blank cardboard package with several small packages inside. Besides Khadas VIM4 SBC, we’ve got a plastic + metal enclosure with screws and screwdriver, two antennas for WiFi and Bluetooth, a USB Type-C power supply, a USB-C cable, an M.2 expansion board, a short […]
Orbbec Persee+ 3D AI camera runs Ubuntu or Android on Amlogic A311D processor
Orbbec Persee+ is a 3D depth camera running Linux with AI capabilities thanks to Amlogic A311D hexa-core processor equipped with a 5 TOPS NPU (Neural-network Processing Unit). The Persee+ is designed to help researchers, engineers, and hobbyists implement advanced uses for 3D imaging. Orbbec has been around for several years with the first product we covered here being the Orbbec Persee 3D depth camera running Ubuntu or Android on Rockchip RK3288 processor and unveiled in 2015. Last year, the company introduced the Zora P1 Amlogic A311D development board for Orbbec 3D cameras, so in a way, the Orbbec Persee+ is born from the work done on the Persee camera and Zora P1 over the years.
