Relative Performance of ARM Cortex-A 32-bit and 64-bit Cores

Many people assume newer processors will be faster, or that 64-bit processor will provide a performance boost compared to 32-bit processors, but the reality can be quite different, and I’ve decided to have a look at ARM Cortex-A cores using ARMv7 (32-bit) and ARMv8 (64-bit) architecture, and see what kind of integer performance you can expect from each at a given frequency. To do so, I’ve simply use DMIPS/Mhz (Dhrystone MIPS/Megahertz) values listed on Wikipedia. Drystone benchmark has no floating-point operating, so it’s a pure integer benchmark. I’m only looking at ARM core here, and once integrated in an SoC, other parameters like memory bandwidth, amount of cache,  GPU, etc.. will greatly affect the overall system performance. The figure above are per MHz, and it does not mean for example that a Cortex A5 processor will be slower than a Cortex A7 processor, as can be seen by the comparison […]

Vortex86DX3 is a New x86 SoC for Embedded Systems

Intel is already making embedded version of their processor with example with Bay Trail-I or Quark SoCs, but Taiwan based DMP Electronics has also been making x86 SoC such as Vortex86EX that can be found in $39 86duino Zero board, which must be one the cheapest, if not the cheapest, x86 board on the market. Of course, this is not designed to run Windows and Office, but rather some embedded (IoT) applications. The company has recently launched Vortex86DX3, a more powerful x86 dual core processor, suited to embedded systems and communication products such as thin clients, NAT routers, gateways, etc… DMP Vortex86DX3 specifications: Dual Core x86 Processor @ 1GHz with 6 stage pipeline, x86 instruction set Floating point – Implements ANSI/IEEE standard 754-1985 for binary Floating-Point Architecture Cache – 8-way 32K I-Cache, 8-way 32K D-Cache,  4-way 512KB L2 Cache with write through or write back policy System DDR3 Control Interface – 32-bit data […]

Intel Celeron N3000 2-in-1 Laptop, and MSI Motherboards with Celeron N3050/N3150 and Pentium N3700 Processors

Intel introduced the first low power Braswell Celeron and Pentium processors with 4 to 6W TDP, meaning a lower power consumption compared to Bay Trail-M processors, and with better performance. The first devices and motherboards based on these have started to show up with Intel’s Orchid Island 2-in-1 Reference Design based on Celeron N3000, and three MSI motherboards: N3050I ECO, N3150I ECO, and N3700I ECO respectively powered by Celeron N3050 dual core processor, Celeron N3150 quad core processor, and Pentium N3700 quad core processor, all clocked @ 1.6GHz (base frequency) and with 6W TDP. MSI did not release full details about their motherboards but we still now they’ll support H.265/HEVC hardware decoding up to 4K, Blu-ray playback and 8-channel HD Audio via an HDMI 1.4b port. Other connectors and interfaces include two DDR3L-1600MHz SO-DIMM slots (up to 8GB), two SATA III ports, one PCIe slot, Gigabit Ethernet, a COM port, […]

How to Easily Install Popular Add-ons in Kodi

You can use Kodi to watch videos locally, but various add-ons can be installed to also access videos online, but finding and installing add-ons might be a pain if you don’t know where to start. TVaddons.co, previously known as XBMCHUB, is providing add-ons allowing to do just that, more or less legally [Update: You may want to read comments for details about the legality of these add-ons], as well as a method to install a bunch of popular add-ons in a few clicks. These add-ons are completely unrelated to Kodi project, and have been developed and maintained by third parties. The installation requires Fusion Installer and Config Wizard with detailed instructions available there with every screenshot, which makes it more complicated than it really is, but it can be summarized as follows: Go to System->File Manager, and click Add source You’ll get the following pop-up window, where you need to […]

VX2 Celeron J1800 / J1900 mini PCs with 500GB Hard Drive Sell for $180 and Up (Promo)

CSQ CSW9 is an Intel Celeron J900 based mini PC with a 500GB HDD that normally sells for a little over $200 on Aliexpress once shipping is included. But today, as I found a list of Geekbuying Coupons via Google+, I noticed the device was listed on Geekbuying as VX2, and both Celeron J1800 and J1900 versions were available for respectively $179.99 and $189.99 after applying MYMVECMY coupon, which looks like a decent deals since a 500GB 2.5″ SATA drive costs about $45. Specifications listed on Geekbuying are mostly the same as for CSQ CSW9 except some difference highlighted in bold or stricken-through when removed: SoC – Intel Celeron J1800 dual core processor @ 2.41 GHz (base) / 2.58 GHz (burst),  or J1900 Quad core processor  @ 2.0 GHz (base) / 2.41 GHz (Burst) with Intel HD graphics (10W TDP) System Memory – 2 GB DDR3L 1066/1333 MHz Storage – […]

Rockchip RK3368 64-bit ARM Android Boxes Are Coming Soon

Yesterday, Rockchip had an event for their Atom x3-C3230RK SoCs (previously known as Sofia)  developed in collaboration with Intel, and upcoming Android 5.1 tablets and smartphones based on the new platform, as well as progress with their first 64-bit ARM SoC (RK3368) that is now integrated into Android TV boxes, albeit still in development. Padnews wrote a summary of the event, but in this post I’ll focus on Rockchip RK3368 hardware. One of the first product will be X6 TV box. Padnews did not have a readable picture with the specs, but Eric of Geekbuying also went to the event, and kindly provided a clear picture with the specs (Mali-600MP is however not the GPU used in RK3368): SoC – Rockchip RK3368 octa core Cortex A53 processor with PowerVR G6110 GPU with support for OpenGL ES 1.x/2.0/3.x, OpenGL 3.2, DirectX 9.3, OpenCL 1.2 EP, and Renderscript System Memory – 1 […]

iPazzPort KP-810-35BTT Backlit Keyboard Features a Switchable Touchpad / Numpad Zone

I’ve read many people praise Logitech K400 Bluetooth keyboard for use with Android mini PCs, as it’s functional and costs just $25 on Amazon. I’ve just come across another similar keyboard with iPazzPort KP-810-35BTT that adds backlit keys and the touchpad zone can be switched to numpad by the touch of a button. Key features listed for the keyboard: Backlit QWERTY keyboard with touchpad supporting multi-touch and scrolling bar. Connectivity – Bluetooth 3.0; max distance: 10m Power Supply – 3x AAA Batteries Dimensions –  314 x 112.5 x 17mm Weight – 218g Material – ABS It’s a standard Bluetooh HID keyboard so it should work with any OS including Windows, Linux, Android, Mac OS, iOS… One possible downside is the lack of left / right mouse buttons. I have such touchpad without separate physical mouse buttons on Acer Aspire E5 laptop, and while a left click is easy to do, […]
