Khadas VIM3 Linux Benchmarks and Comparison to Raspberry Pi 4

Khadas VIM3 Heatsink Fan

I received Khadas VIM3 Amlogic A311D SBC in early July and started testing it with Android running some benchmarks and playing games last month. I was impressed by graphics performance and overall benchmark results in Android, especially the results I got with a heatsink matched Khadas own results with heatsink + fan. So I installed the latest Ubuntu 18.04 available at the time (July 19) in order to repeat benchmarks in Linux and see how it goes. System info in Ubuntu 18.04: I decided to install armbianmonitor to draw some nice temperature charts as I did with  Raspberry Pi 4: But I had some error during installation: And while I can load the webpage with top menu appearing, it won’t show any data, as its name implies it may only work in Armbian. SBC Bench on Khadas VIM3 Let’s download SBC bench: Note that I had to comment out CheckLoad in the script because Amlogic processor’s average will converge to …

Beelink GT-King (Amlogic S922X) TV Box Review

Beelink GT-King YouTube App

Rant Karl here. I have been playing around with Android boxes for several years. Unfortunately, some fundamental issues from when I first started playing around with these boxes are still there. They have come a long way since the MK808 with Rockchip RK3066 processor. The MK808 was my first endeavor into Android on the TV in 2013.  I can’t believe it’s been nearly 6 years. In 2014 Google introduced Android TV and the Nexus Player. It was designed for a TV and controller. The first boxes/sticks adapted the stock Android experience to run on a TV, but without a touch interface the experience was/is not optimal. Sure you get thousands and thousands of apps but a lot of them don’t work. Unfortunately, this hasn’t changed much. If these boxes came with Linux and Android I don’t think I would complain as much. I would consider it a tinkering box. But these boxes are targeted at the average home user and …

Linaro Connect San Diego 2019 Schedule – IoT, AI, Optimizations, Compilers and More

Linaro Connect San Diego 2019

Linaro has recently released the full schedule of Linaro Connect San Diego 2019 that will take place on  September 23-27. Even if you can’t attend, it’s always interested to check out the schedule to find out what interesting work is done on Arm Linux, Zephyr OS, and so on. So I’ve created my own virtual schedule with some of the most relevant and interesting sessions of the five-day event. Monday, September 23 14:00 – 14:25 – SAN19-101 Thermal Governors: How to pick the right one by Keerthy Jagadeesh, Software Engineer, Texas Instruments With higher Gigahertz and multiple cores packed in a SoC the need for thermal management for Arm based SoCs gets more and more critical. Thermal governors that define the policy for thermal management play a pivotal role in ensuring thermal safety of the device. Choosing the right one ensures the device performs optimally with in the thermal budget. In this presentation Keerthy Jagadeesh, co-maintainer of TI BANDGAP AND …

TensorFlow Lite for Microcontrollers Benchmarked on Linux SBCs

TensorFlow Lite microcontrollers benchmark linux SBC

Dimitris Tassopoulos (Dimtass) decided to learn more about machine learning for embedded systems now that the technology is more mature, and wrote a series of five posts documenting his experience with low-end hardware such as STM32 Bluepill board, Arduino UNO, or ESP8266-12E module starting with simple NN examples, before moving to TensorFlow Lite for microcontrollers. Dimitris recently followed up his latest “stupid project” (that’s the name of his blog, not being demeaning here :)) by running and benchmarking TensorFlow Lite for microcontrollers on various Linux SBC. But why? you might ask. Dimitris tried to build tflite C++ API designed for Linux, but found it was hard to build, and no pre-built binary are available except for x86_64. He had no such issues with tflite-micro API, even though it’s really meant for baremetal MCU platforms. Let’s get straight to the results which also include a Ryzen platform, probably a laptop, for reference: SBC Average for 1000 runs  (ms) Ryzen 2700X (this …

Amlogic S912 vs Amlogic A311D/S922X-B Benchmarks Comparison

S922X-B vs S912

A few days ago we compared Amlogic A311D to Rockchip RK3399 since both the top of the line processors from Amlogic and Rockchip that are currently available. Rockchip RK3588 will even be faster, but we need to wait until Q1 2020 at least before it becomes available, and delays are not unheard of, so I’d expect it may take about one year before I can get my hands on a sample. Another comparison is against Amlogic S912, the previous high-end processor from the company. Amlogic A311D and S922X-B are newer and will be faster but it’s interesting to find out just how much. Note the Amlogic S922X found in ODROID-N2 is clocked at a lower speed compare to A311D/S922X-B, so performance will be somewhat lower. Since I recently benchmarked Khadas VIM3 with Amlogic A311D processor, I decided to dust off my old Khadas VIM2 Amlogic S912 development board, fit it a large heatsink, install the latest Android 7.1 firmware for …

5W Intel Tiger Lake-Y Series Processor with Gen12 UHD Graphics Benchmarked

The current high-performance low power 5W Intel processors are part of Amber Lake family, which will be followed by Comet Lake in 2020, and Tiger Lake in 2021 according to a roadmap leaked a few months ago. It looks a little too early for this, but NotebookCheck.net reports an unnamed Intel Tiger Lake Y-series processor has showed up in UserBenchmarks website. The system is said to feature an “Intel TigerLake Y LPDDR4x T4 Crb” motherboard, with an “Intel Tiger Lake Client Platform” coupled with 12GB DDR4 memory. The processor is only named “Intel 000” and comes with 4 cores, 8 threads having a base clock of 1.2 GHz, and an (average) Turbo clock of 2.9 GHz.  The SoC also comes with a Gen12 Intel UHD Graphics, but the computer also features a much faster AMD RX 580 graphics cards so bear this in mind if you’re looking at graphics benchmarks. If true and accurate, the CPU performance is really impressive …

Amlogic A311D vs Rockchip RK3399 Benchmarks Comparison

A311D vs RK3399

I’ve run some benchmarks on Khadas VIM3 SBC earlier this morning. The board is powered by the latest Amlogic A311D hexa-core Cortex-A73/A53 processor, and I’ve found results to be impressive. But let’s see how it compares to another hexa-core processor, namely the popular Rockchip RK3399 Cortex-A72/A53 processor released in 2016 and found in several Chromebooks, TV boxes, and development boards. To do so, I’ve compared Antutu 7.x, PCMark 10 Work 2.0, and 3Dmark benchmark results in Khadas VIM3 board running Android 9, against an actively-cooled Rockchip RK3399 SBC running Android 8.1. The results for A311D should be the same as for Amlogic S922X-B processor, so this post could also serve as an Amlogic S922X-B vs RK3399 comparison. Amlogic A311D vs Rockchip RK3399 – Key features Amlogic A311D Rockchip RK3399 CPU Quad-core Cortex-A73 @ 2.21 GHz Dual-core Cortex-A53 @ 1.8 GHz Dual-core Cortex-A72 @ 1.8 GHz Quad-core Cortex A53 @ 1.416 GHz GPU Arm Mali-G52MP4 ARM Mali-T860MP4 NPU Yes (5.0 TOPS) …
