Rockchip RK3566 Benchmarks in Android 11 (Zidoo M6)

Amlogic S905X4 vs Rockchip RK3566

I received Zidoo M6 last month, a mini PC based on Rockchip RK3566 quad-core Cortex-A55 processor. I initially understood it came with Ubuntu Linux, but actually, it came pre-loaded with Android 11, so I’ve decided to run some benchmarks on the RK3566 device to see how it performs compared to other Arm systems Zidoo M6 system info But before running benchmarks, let’s have a look at some system info with CPU-Z CPU-Z has never heard about RK3566, so it detects it as RK3066, but the rest of the information seems correct with a quad-core Cortex-A55 clocked between 400 MHz and 1.8 GHz, an Arm Mali-G52 GPU, 3775KB RAM, and 24.12 GB internal storage from the 32GB flash. The system runs Android 11 on top of Linux 4.19 which will be supported until December 2024. I can set the video output to 4K, but the UI is still limited to 1920×1080 […]

MINIX NGC-5 Review – Windows 10, Ubuntu 20.04, and external GPU

minix ngc-5 review egpu setup

MINIX has just launched a new mini PC in their NGC range called the NGC-5. Although it uses a somewhat dated Intel eighth-generation Core i5 processor, the integrated Iris Plus Graphics 655 is notable for being one of the more powerful iGPU solutions. MINIX kindly sent one for review and I’ve looked at performance running both Windows and Ubuntu together with using an eGPU. Hardware Overview The NGC-5 physically consists of a 153 x 153 x 43mm (6.02 x 6.02 x 1.57 inches) square plastic case. As an actively cooled mini PC, it uses Intel’s older 14 nm++ Core i5-8279U Coffee Lake processor which is a quad-core 8-thread 2.40 GHz processor boosting to 4.10 GHz with Intel’s Iris Plus Graphics 655. The front panel has just a LED power indicator whereas the rear panel includes dual gigabit Ethernet ports, dual USB 3.1 ports, a DisplayPort 1.2, an HDMI 2.0a port, […]

Getting Started with the Yocto Linux BSP for Polarfire SoC FPGA Icicle Kit

Getting Started Guide PolarFire SoC FPGA Icicle Kit

Last month I received Microchip PolarFire SoC FPGA Icicle development kit that features PolarFire SoC FPGA with a Penta–core 64-bit RISC-V CPU subsystem and an FPGA with 254K LE, and booted it into the pre-installed Linux operating systems based on OpenEmbedded. Today, I’ll show how to get started with the Yocto BSP and run the EEMBC CoreMark benchmark, and I’ll check out the FPGA with Libero SoC Design Suite in a couple of weeks. Operating Systems supported by PolarFire SoC FPGA My initial idea was to focus this part of the review on Linux on RISC-V status, checking some system information, running some benchmarks (e.g. SBC-Bench), compiling the Linux kernel, and installing services like a LEMP stack (Linux, Nginx (pronounced Engine-X), MySQL, PHP) which could be used for WordPress hosting for instance. But then I looked at the operating systems supported with Microchip PolarFire SoC FPGA. There’s a Yocto Linux […]

Benchmarking TinyML with MLPerf Tiny Inference Benchmark

MLPerf Tiny Inference Benchmark

As machine learning moves to microcontrollers, something referred to as TinyML, new tools are needed to compare different solutions. We’ve previously posted some Tensorflow Lite for Microcontroller benchmarks (for single board computers), but a benchmarking tool specifically designed for AI inference on resources-constrained embedded systems could prove to be useful for consistent results and cover a wider range of use cases. That’s exactly what MLCommons, an open engineering consortium, has done with MLPerf Tiny Inference benchmarks designed to measure how quickly a trained neural network can process new data for tiny, low-power devices, and it also includes an optional power measurement option. MLPerf Tiny v0.5, the first inference benchmark suite designed for embedded systems from the organization, consists of four benchmarks: Keyword Spotting – Small vocabulary keyword spotting using DS-CNN model. Typically used in smart earbuds and virtual assistants. Visual Wake Words – Binary image classification using MobileNet. In-home security […]

RasPad 3 Review – Part 2: A Raspberry Pi 4 mini PC with integrated display

Raspad 3 review

I started RasPad 3 review last week with an unboxing of the tablet shell for Raspberry Pi 4, together with assembly instructions, and a first boot after flashing Raspad OS to the system. In the first part of the review, I mentioned that I’d probably focus the remainder of the review on Ezblock Studio visual programming IDE, as the rest of the software is almost the same as using a standard Raspberry Pi 4, the other difference being the touchscreen-friendly RasPad launcher. But Sunfounder explained to me it would be hard to check out Ezblock as it’s designed to control robots and other hardware platforms, and requires an extra HAT (see Kickstarter campaign) to allow the Ezblock APP to connect through Bluetooth (it cannot be directly linked to Raspberry Pi through the built-in Bluetooth).  Here’s an example of a robot that is compatible with Ezblock Studio: Picar-X. Finally, I was […]

GMK NucBox Review – A palm-sized Windows 10 mini PC

GMK NucBox Power Adapter

GMK released their diminutive mini PC called the NucBox a while ago however they have recently updated the BOM with a new fan and WiFi module together with changing their logo from GMK to GMK TEC. GMK sent the new NucBox for review and the results from various testing are detailed below. Hardware Overview The NucBox physically consists of a 62 x 62 x 42mm (2.44 x 2.44 x 1.65 inches) rectangular metal case with a plastic top and base plate. As an actively cooled mini PC, it uses Intel’s 14 nm J4125 Gemini Lake Refresh processor which is a quad-core 4-thread 2.00 GHz processor boosting to 2.70 GHz with Intel’s UHD Graphics 600. The front has just the power button whilst the rear includes two USB 3.0 ports, an HDMI port, and a Type-C USB port for power. The left side has a microSD card slot and a headphone […]

GMK NucBox2 Review – Windows 10, Unraid OS on a Coffee Lake mini PC

GMK NucBox2 Review

Karl here. Today we are going to look at a mini PC. It is by GMK. GMK’s first foray looks to be the NucBox, a super tiny mini pc. I would call the NucBox2 its older, bigger, more capable brother. What stood out to me was the M.2 4x NVMe slot. I don’t anticipate a superfast SSD to come with the NucBox2 but we will see. The NucBox2 only had one 8 GB stick of memory and I had an extra stick laying around so I installed it to get dual-channel support. I think they are doing this mini PC a disservice using memory in single-channel mode. A quick Google search shows an 8GB stick is about $50 and I would highly recommend this upgrade. Notable Specs Processor – Intel Core i5-8259U 4-core/8-thread Coffee Lake processor 802.11 AC WiFI M.2 NVMe 256 GB SSD (Netac) 8GB memory single-channel Gig Ethernet […]

Using an eGPU with a mini PC

using r43sg egpu with mini PC

Mini PCs have grown in popularity in part due to their small form-factor offering low-powered basic computing with sufficient ports for connectivity. As such they are useful both in commercial settings such as digital signage as well as with consumers needing a small-footprint or VESA-mounted low-cost computer. However, one drawback is their limited graphical performance due to using CPUs with integrated graphics which results in the options for playing games being somewhat restricted and ‘AAA’ titles typically being unplayable. Lower-priced laptops often share the same drawback and one of the ways that users have addressed their graphical need is by utilizing an external GPU (eGPU) however the commercially available ones are both expensive and require connecting via a Thunderbolt 3 port. Unfortunately, not many Chinese-made mini PCs currently include a Thunderbolt 3 port however now that they have started to include M.2 NVMe ports this has created the possibility of […]
