Linux Benchmarks – Intel J3455 Apollo Lake vs Z3735F Bay Trail vs RK3399 and Other ARM Platforms

Since I’ve just installed Ubuntu 17.10 on MeLE PCG35 Apo, I decided I should also run some benchmarks comparing with other ARM and x86 Linux platforms I’ve tested in the past.I was particularly interested to compare the performance of Intel Apollo Lake processors (Celeron J3455 in this case) against higher end ARM processors like Rockchip RK3399 (2x A72, 4x A53) since systems have a similar price (~$150+), as well as against the older Bay Trail processor to see the progress achieved over the last 2 to 3 years. To do so, I used Phoronix Benchmark Suite against Videostrong VS-RK3399 results (RK3399 development board):

sudo apt install php-cli php-gd php-xml php-zip 
wget http://phoronix-test-suite.com/releases/repo/pts.debian/files/phoronix-test-suite_7.4.0_all.deb 
sudo dpkg -i phoronix-test-suite_7.4.0_all.deb
phoronix-test-suite benchmark 1709271-TY-1704029RI26

sudo apt install php-cli php-gd php-xml php-zip

wget http://phoronix-test-suite.com/releases/repo/pts.debian/files/phoronix-test-suite_7.4.0_all.deb

sudo dpkg -i phoronix-test-suite_7.4.0_all.deb

phoronix-test-suite benchmark 1709271-TY-1704029RI26

The benchmark first issued a warning about “powersave” governor, but I still went ahead, and once completed I change it to “performance” governor:

sudo apt install cpufrequtils
sudo cpufreq-set -r -g performance

1 2	sudo apt install cpufrequtils sudo cpufreq-set -r -g performance

…and ran the tests again. All results are available on OpenBenchmarking. Let’s address the governor results first. cpufreq-info reports that powersave governor […]

Nerdonic Exen Mini is the World’s Smallest 32-bit Arduino Compatible Board (Crowdfunding)

Back in June, we reported about μduino board, which at 12×12 mm may well be the world’s smallest Arduino compatible board. It is based on Microchip Atmel ATMEGA32U4 8-bit AVR microcontroller. But there’s now a new board in town which claims to be the world’s smallest 32-bit Arduino board: Exen Mini measuring 14.9×14.9 mm. While I’m patiently waiting for an Intel’s DMCA request, or more likely an email requesting an update once the name has changed, like I had to do for Atomwear Vigekwear, let’s have a look at what the board has to offer. Exen Mini specifications: MCU – Microchip Atmel SAMD21 Cortex M0+ MCU @ 48 MHz with 256KB flash, 32KB SRAM I/Os via 2x 5-pin 2.54mm pitch headers Up to 8x digital I/O Up to 8x PWM Up to 6x analog (ADC) 1x UART 1x I2C 1x reset Limits – 3.7V, 7mA USB – 1x micro USB […]

Banana Pi M2 Magic Board Now Sold with Allwinner A33 Processor for $23

Banana Pi M2 Magic development board was first unveiled in February of this year with an Allwinner R16 SoC, 512 MB RAM, and 8GB eMMC flash, and its main selling points were support for MIPI DSI LCD displays, CSI cameras, and 3.7V LiPo batteries. AFAIK SinoVoIP never sold that version of the board, at least on Aliexpress. Possibly due to the intricacies of Allwinner business units, the company has now officially launched Banana Pi M2 Magic (aka BPI M2M), but replaced Allwinner R16 by the similar Allwinner A33 processor, and removed the 8GB eMMC flash to bring the price down to $23 plus shipping. The “old” Allwinner R16 based Banana Pi M2 Magic board will apparently be sold as M2 Magic Plus soon. Banana Pi BPI-M2 Magic (A33) specifications: SoC – Allwinner A33 quad core ARM Cortex-A7 processor with ARM Mali 400 MP2 GPU System Memory – 512MB DDR3 Storage […]

STEGO BOARD Enables Neat Prototypes with Development Boards and Accessories (Crowdfunding)

If you’ve ever created a quick prototype for your own use, or for your company, you may have based it on a development board, and added some extra modules or add-on modules, as well as potentially accessories such as hard drives or power supply. Software is complete and it works, but it may look like a mess, and transporting it may cause cables to disconnect or other problems. STEGO BOARD should help in this case. It’s some kind of mounting systems compatible with the most common boards like Raspberry Pi 3, Rock64, or ASUS Tinkerboard, mini-ITX motherboards, mini PCs with VESA mounts, 2.5″ and 3.5″ drives, and so on. So you can create prototypes like the ones below. Six different products are available: STEGO BOARD 102 – 2 layers of the smaller board with 106 parts (stands, screws, zip ties). Can be used with mini PC, development board, up to […]

This TTGO Board Combines ESP32, LoRa Radio, and OLED Display for just $10

Just one year ago, it would cost around $15 to $20+ to get an ESP32 board, that is if you were lucky/fast enough to order one one before it went out of stock. Since then, availability is no longer an issue, and you now can get an ESP32 development board for as low as about $7, or even around $4 during promotions. Today, I was made aware of another board sold under the “TTGO” brand, that includes not only ESP32 WiFi and Bluetooth SoC, but also a (433 MHz) LoRa radio, and an OLED display. Price? Just $10 plus shipping ($1.75 here). TTGO ESP32/LoRa board specifications: WiSoC – Espressif ESP32 Storage – 32MB on-board flash (or maybe just 16MB?) LoRa Semtech SX1278 with u.FL connector + 433MHz antenna (N.B.: Antenna must be connected during use or the Semtech chip could be damaged) Sensitivity” ~ -148dBm; output power: +20dBm Display – […]
