Khadas VIM4 – An Amlogic A311D2 SBC with 8GB RAM, Wi-Fi 6, HDMI input & output

We’ve just written about the Amlogic A311D2 processor with some pretty interesting features, and Khadas VIM4 will be one of the first single board computers equipped with the latest octa-core processor, succeeding the company’s earlier Khadas VIM3 board powered by an Amlogic A311D hexa-core processor. Khadas VIM4 makes good use of the extra memory allowance with faster 8GB LPDDR4 RAM, and also offers 32GB eMMC flash, Gigabit Ethernet, WiFi 6, 4Kp60 HDMI input and output, independent USB 3.0, and PCIe (via M.2 socket) interfaces, and more. Khadas VIM4 specifications with bold highlights showing the differences with the VIM3 Pro model: 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, NPU shown as TBD possibly due to license requirements System Memory- 8GB LPDDR4X @ 2112 MHz Storage – 32GB eMMC […]

Dune HD RealBox 4K TV Box Runs Android and Linux on Realtek RTD1395 SoC

Realtek RTD1395 processor is designed for 4K HDR TV boxes and set-top boxes. Equipped with a quad-core Cortex-A53 processor and Mali-470 GPU it offers a lower-cost alternative to Realtek RTD1295 and RTD1296 with the same 4K video processing and playback capabilities. So far, we had seen it in TV boxes designed for operators and Banana Pi BPI-M4 single board computer, but Dune HD RealBox 4K TV box is the first RTD1395 consumer device sold directly to end-users. Dune HD RealBox 4K specifications: SoC – Realtek RTD1395 quad-core Cortex-A53 processor with Mali-470MP4 GPU System Memory – 2 GB RAM Storage – 16 GB flash, MicroSD card slot Video Output – HDMI 2.0a up to 4Kp60 HDR and AV port (composite) Audio – Optional S/PDIF, analog stereo audio via AV port, digital audio via HDMI port; HDMI audio pass-through to AV receiver Video Playback 4Kp60 HDR/HDR10+ with 10-bit H.265 and VP9 profile-2, […]

Raspberry Pi 4 vs ODROID-C4 Features Comparison

Yesterday, Hardkernel launched ODROID-C4 Amlogic S905X3 SBC as an update to ODROID-C2 SBC launched in 2016. We’ve seen the board can compete with Raspberry Pi 4 4GB board thanks to benchmarks released by Hardkernel, but since those boards are so versatile, meaning they can be used in a variety of applications, it’s impossible to benchmark all use cases. One way to find out which board might be right for your application without going through benchmarks is to look at a list of features for each, and that’s exactly what we’ve done in this post. Let’s get straight to the Raspberry Pi 4 (4GB RAM) vs ODROID-C4 comparison table. Features/Specs Raspberry Pi 4B (4GB) ODROID-C4 Release date 24th June 2019 23rd April 2020 SoC Broadcom BCM2711 quad-core Cortex-A72 @ 1.5 GHz (overclockable to 2.0+ GHz) with NEON, FPU Amlogic S905X3 quad-core Cortex-A55 processor @ 2.0 GHz with NEON, FPU, Armv8 Crypto […]

X96Q Android 10 TV Box Shows Up with Allwinner H313 Quad-core Cortex-A53 Processor

It looks like Allwinner has come up with a new confusing processor. Allwinner H3 is a popular quad-core Cortex-A7 processor that’s been around for years, but the company has now launched an Allwinner H313 quad-core Cortex-A53 processor that’s found in some TV boxes running Android 10, namely X96Q with 1 to 2 GB RAM, and 8 to 16GB storage. X96Q TV box specifications: SoC – Allwinner H313 quad-core Arm Cortex-A53 processor @ 1.35 GHz with Arm Mali G31 MP2 GPU with support for OpenGL ES 3.2 and Vulkan System Memory – 1GB/2GB SDRAM Storage – 8GB/16GB eMMC flash, MicroSD card slot Video & Audio Output – HDMI 2.0a up to 4K @ 60 Hz, AV port for video composite + stereo audio Video Codecs VP9 Profile-2 up to 4K 30fps H.265 Main10 @ L5.1 up to 4K 60fps AVS2 JiZhun 10-bit Profile up to 4K 60fps H.264 BP/MP/HP @ L4.2 […]

SDMC DV8919 Amlogic S905X4 Android TV 10 TV Box Supports AV1 Decoding

We’ve previously covered several TV box & set-top box SoCs with support for the royalty-free AV1 video codec including Broadcom BCM7218X SoC, and Amlogic S805X2, S905X4, and S908X processors. But so far, apart from an AV1 demo on the RTD1311/RTD1319 development board (Pymparticle EVB?), and new about Technicolor Jade STB, I had not really seen AV1-capable TV boxes so far. SDMC DV8919 appears to be the first Amlogic S905X4 TV box on the market and one of the first running the recently released Android 10 on Android TV OS. SDMC DV8919 specifications: SoC – Amlogic S905X4 quad-core Arm Cortex-A55 processor @ up to 2.0 GHz with Arm Mali-G31MP2 supporting OpenGL ES3.2, Vulkan 1.1 and OpenCL 2.0 System Memory – 2GB DDR memory (options: 1GB or 4GB) Storage – 8GB eMMC flash (options: 16GB, 32GB, 64GB), MicroSD card slot Video Output – HDMI 2.1 up to 4K @ 60+Hz with CEC […]

NanoPi M4V2 Kit Review – Part 2: FriendlyCore Desktop

We’ve already seen how to assemble NanoPi M4V2 metal case kit which offers an Arm mini PC solution with support for NVMe SSD. The new NanoPi M4V2 Rockchip RK3399 SBC is an evolution of the M4 board that brings faster LPDDR4 memory and adds power & recovery buttons. Since we’ve already tested several RK3399 SBC‘s and TV boxes, I planned to focus the review on thermal design evaluation (i.e. see how well the board cools), and see how memory bandwidth evolved from LPDDR3 to LPDDR4. I wanted to do so both with Linux and Android, since I could compare NanoPC-T4 (LPDDR3) benchmarks in Android. But this requires an eMMC flash module, and I don’t own any. So instead I planned to run Armbian because of support for armbian-monitor for nice temperature chart but it’s not working just yet, so instead I’ve done all tests with FriendlyCore Desktop (rk3399-sd-friendlydesktop-bionic-4.4-arm64-20190926.img) based on […]

Khadas VIM3L SBC Review with Android 9 Firmware

Khadas VIM3L is the first and so far only Amlogic S905D3 SBC on the market, so I first ran some benchmarks and checked system info. But it is also designed to be an HTPC, I’ll continue the review with some 4K video and audio playback testing, some gaming, and I/O benchmarks. Khadas VIM3L Unboxing As you may remember (or not), VIM3L ships either as a bare board pre-loaded with Android 9 or as an HTPC kit with the board running CoreELEC. I’ve received the bare board which also comes with two WiFi antennas. It can do much more than a simple TV box however, since it also comes with an M.2 NVMe socket (extra adapter board required), and sockets with MIPI DSI + touchscreen, and MIPI CSI camera. It’s one of the few boards with a low profile Ethernet connector, so if you ever wanted to build a farm of […]

4K Video Playback on Raspberry Pi 4 with LibreELEC (Alpha)

In my short Raspberry Pi 4 review, I tested 4K video output and playback in Raspbian, and sadly neither are working properly, with video output stuck to 1080p60 even after selecting 4K HDMI in the settings and yes, I double checked for “hdmi_enable_4k=1” in config.txt, while H.265 video playback is still clearly using software decode in both VLC and omxplayer. However, LibreELEC team announced support for Raspberry Pi 4 in LibreELEC 9.2 Alpha1 release based on Kodi 18.3 and Linux 4.19.x. So I downloaded LibreELEC-RPi4.arm-9.1.001.img.gz and flash it to a microSD card with balenaEtcher. The good news is that I could manually set the resolution to 3840×2160 and confirm it works with my TV, but the refresh is limited to 30 Hz maximum. Other refresh rates currently available include 23.98 Hz, 24 Hz, 25 Hz, and 29.97 Hz. The hardware is capable if 4K 60Hz, so it’s just a question […]
