Beelink GTi11 Review – Part 1: Tiger Lake mini PC with Windows 11

Beelink GTI11 review

Beelink’s GTi11 is the latest offering in their ‘GT’ series of slightly larger mini PCs that are notable for expandable storage configurations together with multiple ports and characterized by including a fingerprint scanner. Featuring Intel’s 11th generation Tiger Lake processors, Beelink kindly sent an i5 version for review which I will undertake in three parts. In this first part, I’ve looked at Windows performance and the second part will cover Ubuntu with the third part looking at various configuration mods. Beelink GTi11 Hardware Overview The GTi11 physically consists of a 168 x 120 x 39mm (6.61 x 4.72 x 1.54 inches) rectangular metal case. As an actively cooled mini PC, it uses Intel’s ‘10 nm SuperFin’ Tiger Lake processors and the review model included an i5-1135G7 which is a quad-core 8-thread 2.50 GHz Core processor boosting to 4.20 GHz with Intel’s Xe Graphics. The front panel has an illuminated power […]

Rockchip RK3588 benchmarks – Geekbench4, GFXBench, Antutu

RK3588 benchmarks

We’ve been talking about the Rockchip RK3588 Cortex-A76/A55 processor since it showed up in a roadmap in the Spring of 2019, and the initial plan was for a release in Q1 2020. But as most regular readers know, there have been delays after delays, and some people have even started to associate RK3588 with vaporware. But there may be light out of the tunnel with Rockchip RK3588 platform being showcased at the Rockchip Developer Conference 2021, notably with CPU and GPU benchmarks for the device. The results for Geekbench 4 reveal around 2.7 times (single core) or 3.4 times (multi-core) higher CPU speed, but the most impressive part is the GPU as GFXBench shows Rockchip RK3588 being multiple times faster than RK3399, in some cases over 10 times faster. A few weeks ago, we noted some Geekbench 4 results with a system running Android 12 with 8GB of RAM, and […]

A deep dive into Raspberry Pi Zero 2 W’s power consumption

Raspberry Pi Zero 2 W Power Consumption measurements with Otii Arc

When I completed my review of Raspberry Pi Zero 2 W, I mentioned I would test the power consumption of the board later. It took a while, but I’ve finally come around it using Otii Arc from Qoitech and Otii software to provide some pretty power consumption charts, and even energy consumption. Since the Raspberry Pi Foundation recommends a 5V/2.5A power supply, I’ll first try to get as close as possible as 2.5A, then I’ll go through tricks to reduce idle power consumption to less than 75 mA / 375 mW, and finally check the energy consumption under various CPU core count and frequency. Raspberry Pi Zero 2 W Power consumption under load, with accessories I started with the latest Raspberry Pi OS Lite “Bullseye” image and connected my Raspberry Pi Zero 2 W board to Qoitech Otii Arc tools as shown below. It used to cost around $500, but […]

Raspberry Pi Zero 2 W mini review – Benchmarks and thermal performance

Raspberry Pi Zero 2 W Heatsink

The Raspberry Pi Foundation launched the Raspberry Pi Zero 2 W board yesterday with the main difference against Raspberry Pi Zero W board being the much faster Raspberry Pi RP3A0 SiP with a Broadcom quad-core Cortex-A53 processor clocked at 1.0 GHz and overclockable to 1.2 GHz. I received my sample shortly after publishing the announcement, and I had time to test it. Since the main difference is the processor, I’ll focus this review on benchmarks and whether additional cooling is required for the board. Raspberry Pi Zero 2 W kit unboxing If you purchase the board for $15, that’s all you’ll get, but Raspberry Pi Trading sent me a kit with Raspberry Pi Zero 2 W SBC, a USB OTG adapter, a mini HDMI to HDMI adapter, the CSI camera cable, and four rubber pad for the enclosure that comes with three covers: full, hole for 40-pin GPIO header, or […]

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 […]
