Amlogic A311D vs Rockchip RK3399 Benchmarks Comparison

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 […]

Khadas VIM3 (Amlogic A311D) Benchmarks & System Info in Android 9

I received Khadas VIM3 kit at the very beginning of this month, and showed the content of the kit, and how to assemble it. Now after clearing some other items for review, I’ve started to play with the Amlogic A311D board which ships with Android 9.0 by default. I’ll focus my efforts on Ubuntu as most people will run Linux distributions on the board, but before doing so I’ve upgraded Android to the latest version, and checked out system information and ran some benchmarks in Android. Installing the latest Android firmware on VIM3 Instructions to upgrade the firmware over USB-C are available for Windows and Ubuntu, but since my laptop runs Ubuntu 18.04 I’ll focus on the latter. We can install the burn-tool for Linux as follows:

sudo apt install libusb-dev git parted
git clone https://github.com/khadas/utils
cd utils
sudo ./INSTALL

sudo apt install libusb-dev git parted

git clone https://github.com/khadas/utils

cd utils

sudo ./INSTALL

We can now download and extract the latest Android image:

wget https://dl.khadas.com/Firmware/VIM3/Android/VIM3_Pie_V190704.7z
7z x VIM3_Pie_V190704.7z

1 2	wget https://dl.khadas.com/Firmware/VIM3/Android/VIM3_Pie_V190704.7z 7z x VIM3_Pie_V190704.7z

Once it’s done you can connect your VIM3 board to your […]

AFRd Auto Frame Rate Daemon Works with 64-bit Amlogic Processors

Automatic frame rate switching in TV box ensures video output matches the video frame rate in order to avoid skipped frames (judder) from time to time, and makes the videos much smoother to watch, especially to trained eyes. The problem is that the feature is not always implemented, and/or does not work for all apps. AFRd auto frame rate daemon aims to solve this issue by automatically switching video output to match the video framerate – e.g. 23.976 fps or 59.94 fps – on Android TV boxes powered by one of Amlogic 64-bit processors, be it S905, S905X, S905X2, S912, S905W and other more recent Armv8 processors from the company. Developed by Andrey Zabolotny (anpaza), AFRd is Linux daemon can be linked to either bionic for Android, or glibc for Linux operating systems, and the source code can be found on Github. It relies on two techniques to detect the […]

Beelink GT1 Mini 2 Amlogic S905X3 TV Box is Now Sold for $70

Around two weeks ago, we covered Beelink GT1 Mini 2 that was one of the first TV boxes to get an Arm Cortex-A55 processor, namely the latest Amlogic S905X3 quad-core processor, and the company also shared benchmarks showing Amlogic S905X3 was only marginally faster than Amlogic S905X2 quad-core Cortex-A53 SoC. As shown in our S905X3 vs S905X2 comparison, the main improvements for the former are the presence of an NPU for AI acceleration, and support for faster DDR4 memory up to 3,200 MHz. Upon the announcement, one person noticed the TV box was sold for $80 on GearBest with the default configuration of 4GB RAM and 64GB storage, and while the price has now dropped to $73.99 on GB, Beelink GT1 Mini 2 can now be purchased found for just $69.99 on Aliexpress including worldwide shipping. Beelink GT1 Mini 2 specifications: SoC – Amlogic S905X3 quad-core Arm Cortex-A55 processor @ […]

Amlogic S905X2 vs S905X3 – Features Comparison

Despite Arm claiming Cortex-A55 core would bring some performance improvements, we’ve recently seen actual Amlogic S905X3 benchmarks show the performance compared to Amlogic S905X2 Arm Cortex-A53 is almost identical (3% improvement for S905X3 CPU, 9% for the GPU). So Amlogic S905X3 TV box processor must differentiate itself from its predecessor by its additional features, and while we published the detailed specifications of Amlogic S905X3 processor a few months ago, we did not provide a side-by-side comparison table just yet. So here’s one courtesy of SDMC (with some corrections). SoC Amlogic S905X2 Amlogic S905X3 CPU 4x Arm Cortex-A53 @ 1.80 GHz 4x Arm Cortex-A55 @ 1.91 GHz Neural Network Accelerator N/A Optional 1.2 TOPS NNA GPU Mali-G31 MP2 with OpenGL ES 3.2, Vulkan 1.0, and OpenCL 2.0 Always-on MCU Cortex-M3 & Cortex-M4 (Optional ) Cortex-M3 & Cortex-M4 DDR DDR3-2133 /DDR3L-2133 / DDR4-2666 /LPDDR3-2133 /LPDDR4-3200 SDRAM up to 4G DDR3-2133 /DDR3L-2133 / […]

Linux 5.2 Release – Main Changes, Arm, MIPS & RISC-V Architectures

Linus Torvalds announced the release of Linux 5.2 last Sunday: So I was somewhat pre-disposed towards making an rc8, simply because of my travels and being entirely off the internet for a few days last week, and with spotty internet for a few days before that [*]. But there really doesn’t seem to be any reason for another rc, since it’s been very quiet. Yes, I had a few pull requests since rc7, but they were all small, and I had many more that are for the upcoming merge window. Part of it may be due to the July 4th week, of course, but whatever – I’ll take the quiet week as a good sign. So despite a fairly late core revert, I don’t see any real reason for another week of rc, and so we have a v5.2 with the normal release timing. There’s no particular area that stands […]

Amlogic A311D and S922X-B Processors Support 8K VP9 Video Decoding

We’ve already written about future processors that will support 8K video decoding, such as Rockchip RK3588 that is expected to launch in early 2020. But I’ve just read claims that Amlogic A311D and S922X-B processors could also decode VP9 8K at 30 fps. So let’s have a look at Amlogic A311D datasheet first: Amlogic Video Engine (AVE-10) offloads the Cortex-A53 CPUs from all video CODEC processing. It includes dedicated hardware video decoder and encoder. AVE-10 is capable of decoding 4Kx2K resolution video at 75fps with complete Trusted Video Path (TVP) for secure applications and supports full formats including MVC, MPEG-1/2/4, VC-1/WMV, AVS, AVS+, AVS2 RealVideo, MJPEG streams, H.264, H265-10, VP9 and also JPEG pictures with no size limitation. The independent encoder is able to encode in JPEG or H.265/H.264 up to 1080p at 60fps There’s only mention of 4Kx2K decoding at up to 75fps, and further down in the document, […]

Beelink GT1 Mini 2 TV Box Gets an Amlogic S905X3 Processor

Beelink GT1 Mini TV Box powered by Amlogic S905X2 was launched with Android 8.1 in October 2018, and the company informed us they have an upcoming upgrade, the Beelink GT1 Mini 2, with the same form factor by an upgraded Amlogic S905X3 quad-core Cortex-A55 processor. GT1 Mini 2 is not the first TV box announced with S905X3, as we previously covered Elebao X3 that was supposed to launch at the end of May. So there clearly has been delays, but this time the launch should be closer as Beelink also shared benchmarks and system information from Android 9.0. Beelink GT1 Mini 2 Beelink GT1 Mini 2 preliminary specifications: SoC – Amlogic S905X3 quad-core Arm Cortex-A55 processor @ 1.9 GHz with Arm Mali-G31MP2 GPU System Memory – 4GB DDR4 RAM Storage – 64GB eMMC flash, Micro SD slot Video & Audio Output HDMI 2.1 up to 4K @ 60 Hz with […]
