Khadas VIM4 Review – Part 2: Android 11 preview and benchmarks

Khadas VIM4 Android 11 Review

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 […]

T-Dongle ESP32-S2 WiFi development board comes with two USB OTG ports

ESP32-S2 USB development board

LilyGO has been very busy in recent weeks, and their latest product is the “T-Dongle ESP32-S2” development board that looks very much like Espressif ESP32-S3-USB-OTG board development board but is equipped with the single-core WiFi-only ESP32-S2 processor instead of the dual-core ESP32-S3 SoC with WiFi 4 and Bluetooth 5.0.

AMD Ryzen 5000 C-Series processors target Chrome OS devices for work

AMD Ryzen 5000-C Series

AMD has just introduced the 15W Ryzen 5000 C-Series “Zen 3” processors for premium Chrome OS devices designed for work and collaboration. The processors can with up to eight cores and sixteen threads and are said to offer all-day battery life. AMD Ryzen 5000 C-Series processors for Chrome OS are expected to offer up to 67% faster responsiveness and up to 85% better graphics performance when comparing a Chromebook based on AMD Ryzen 7 5825C against an earlier model based on AMD Ryzen 7 3700C introduced in 2020 using respectively WebXPRT 3 and Motion Mark 1.2 benchmarks. Multitasking performance comparison using Geekbench 5 shows a 107% improvement that is probably mostly due to the doubling of the number of cores. The AMD Ryzen 5000 C-Series “”Barcelo” family is currently comprised of four parts. We can look at the Ryzen 7 5825C other features for more details: Cache –  512KB L1 […]
