Khadas Captain / Edge SBC Review – Part 2: Ubuntu 18.04

I received Khadas Edge Developer Package with Khadas Edge RK3399 module, Khadas Captain carrier board, and several accessories a few weeks ago, and after checking the hardware in the first part of the review, I’ve now taken the time to review software support, specially Ubuntu 18.04 on the board. Khadas Edge / Captain Firmware There are currently four main choices of firmware for Khadas Edge / Khadas Captain: Ubuntu 18.04 OS with LXDE desktop environment @ https://dl.khadas.com/Firmware/Edge/Ubuntu/ Android ROM @ https://dl.khadas.com/Firmware/Edge/Android/ with Android Nougat being a proper release, Android Oreo (available now) a temporary version that will not be supported, and Android P that will be released and supported by Rockchip later on in 2019 Armbian RK3399 for Khadas Edge looks to be work-in-progress right now LibreELEC for playing videos on the platform I decided to focus on Ubuntu 18.04 for this review, and Karl who has his own sample […]

$6 C-SKY Linux Board Reviewed, Benchmarked

The price of single board computers and development boards has really gone down in recent years, and it’s easy to find a low cost Arm based board for most project. But C-SKY Linux development board is quite different since it’s based on the little known C-SKY architecture, and the price in China ($6) is really competitive for a media capable board. If you live outside of China, the board is now sold for about $18 including shipping, and MickMake decided to buy one to have a closer look and review the board. As we covered during the announced the board is powered by NationalChip GX66058 C-SKY 32-bit processor clocked at up to 574 MHz and integrating 64MB DDR2 on-chip. Getting the board on-hand allowed Mick to get more details about the other chips included in the board namely: STMicro STM32F103 to handle all the JTAG control through a micro USB […]

Amazon EC2 A1 Arm Instances Deliver up to 45% Cost Savings over x86 Instances

Just a couple of days ago, Amazon introduced EC2 A1 Arm instances based on custom-designed AWS Graviton processors featuring up to 32 Arm Neoverse cores. Commenters started a discussion about price and the real usefulness of Arm cores compared to x86 cores since the latter are likely to be better optimized, and Amazon Web Services (AWS) pricing for EC2 A1 instances did not seem that attractive to some. The question whether it makes sense will obviously depend on the workload, and metrics like performance per dollar, and performance per watt. AWS re:Invent 2018 is taking place now, and we are starting to get some answers with Amazon claiming up to 45% reduction in costs. It sounds good, except there’s not much information about the type of workload here. So it would be good if there was an example of company leveraging this type of savings with their actual products or […]

An Attempt to Benchmark Entry-level x86 Boards against RK3399 & Exynos Arm Boards

Some Arm boards have become quite powerful, while hardware based on low power Intel processor has generally become cheaper with both architectures somewhat converging in terms of performance and price. Piotr Maliński got interested and purchased some low cost (<$150) Intel hardware to compare to mid-range Arm boards, throwing a Raspberry Pi 3 B+ into the mix as well for comparison. Those are the Intel test boards / computers: Qotom motherboard with Intel Atom Z3735F Bay Trail processor, 2GB RAM, 32GB flash – $74 + shipping on Aliexpress Piesia nano ITX board with Intel Celeron N2806 Bay Trail processor, DDR3 SO-DIMM socket, SATA / mSATA interfaces – Piotr found it for around $85 on Aliexpress, but the price now jumped to over $150 plus shipping, which does not make it very attractive Generic thin mini ITX motherboard based on Celeron N3160 “Braswell” processor, DDR3 SO-DIMM socket, SATA / mSATA interfaces. $62.68 […]

HiSilicon Kirin 980 Benchmarks Show Cortex A76’s Impressive Performance & Efficiency Improvements

HiSilicon Kirin 980 was the first processor announced with Cortex A76 cores, which were said to deliver laptop-class performance, with 35% performance improvement over Cortex A75, and around twice the performance of Cortex A73 cores thanks to improvements, and a higher CPU frequency up to 3.0 GHz. But now that Huawei Mate 20 / Mate 20 Pro smartphones are out, various reviews have been published, and Anandtech was mostly able to confirm the claims. In most case, actual results were inline with expectation despite Kirin 980 clock speed being “limited” to 2.6 GHz. Looking at GeekBench 4 single-thread integer and floating-point scores, the Cortex A76 core based Kirin 980 is significantly faster than Cortex A73 powered Snapdragon 835 clocked @ 2.45 GHz. Precisely: 1.77x faster in the integer score,and 2.21x faster in the floating point score. SPECS2006 confirmed the good performance with 1.89x higher integer score, and 2.04x faster for […]

Beelink X55 Review – An Intel Gemini Lake mini PC Tested with Windows 10 and Linux

The Beelink X55 is very similar in style to Intel’s NUC7PJYH NUC reviewed earlier except that it is not a kit but a fully functional Windows mini PC. It is physically small consisting of an approximately 4.5″ by 4” case about 1¾” tall with a front panel that includes the power button and a couple of USB ports and a headphone jack with the rest of the ports including two HDMI (2.0) ones at the rear: The specifications include: The key highlights are that the Beelink X55 comes a 128GB mSATA SSD with pre-installed Windows 10 Home together with 8GB DDR4 RAM (soldered and is non-expandable) and space plus a connector for an SSD. Starting with a quick look at the hardware information shows it is mostly aligned to the specification but see the note below about the memory: As usual I ran my standard set of benchmarking tools to […]

Baikal T1 MIPS Processor – The Last of the Mohicans?

CNXSoft: Guest post by Blu about Baikal T1 development board and SoC, potentially one of the last MIPS consumer grade platforms ever. It took me a long time to start writing this article, even though I had been poking at the test subject for months, and I felt during that time that there were findings worth sharing with fellow embedded devs. What was holding me back was the thought that I might be seeing one of the last consumer-grade specimen of a paramount ISA that once turned upside-down the CPU world. That thought was giving me mixed feelings of part sadness, part hesitation ‒ to not do some injustice to a possibly last-of-its-kind device. So it was with these feelings that I took to writing this article. But first, a short personal story. Two winters ago I was talking to a friend of mine over beers. We were discussing CPU […]

Beelink X45 Mini PC Review with Windows 10 and Ubuntu 16.04/18.04

The Beelink X45 mini PC is now available, and Lightinthebox.com have provided a unit for review. It is very similar in style to Intel’s latest NUC Windows mini PC, the NUC7CJYSAL reviewed earlier. However it contains an Intel Celeron Processor J4105 SoC which is a quad core processor bursting up to 2.50 GHz together with the Intel UHD Graphics 600 processor that is capable of 4K support at 60Hz. It is physically small consisting of an approximately 4.5″ by 4” case about 1¾” tall with a front panel that includes the power button and a couple of USB ports and a headphone jack with the rest of the ports including two HDMI (2.0) ones at the rear: The specifications include: A key point to note is the Beelink X45 comes with 64GB eMMC with pre-installed Windows 10 Home together with 4GB DDR4 RAM (soldered and is non-expandable) with space and […]
