Qualcomm Snapdragon 800 MDP Benchmarks

A few days ago, I saw some benchmark results showing Xiaomi M3 smartphone powered by Snapdragon 800 SoC getting a ridiculous score above 80,000 points in Antutu, but thought it was really odd, and it turned out to be a fake Antutu screenshot. The actual scores for Snapdragon 800, are much lower, yet one of the fastest mobile platform ever, according to benchmarks performed by Engadget, which hold of Qualcomm Snapdragon 800 Tablet and Smartphone MDPs. Engadget provided comparison of the benchmark for 12 devices, but I selected the 4 most powerful of the lot in the table below. S800 MDP tablet (MSM8974) S800 MDP phone (MSM8974) Samsung Galaxy S4 (Exynos 5 Octa) Nvidia Tegra 4 ref device Quadrant 2.0 20762 22022 13326 16436 Vellamo 2.0 2997 2914 1977 N/A AnTuTu 3.x 35783 33828 28167 36305 SunSpider 0.9.1 (ms) 543 566 732 499 SunSpider 1.0 (ms) 657 674 N/A N/A […]

AMD “Seattle” Server CPU to Pack up to 16 ARM Cortex A57 Cores

AMD has published a roadmap for the rest of 2013 and 2014 for its server processors, and among all the x86 “Jaguar”, “Warsaw” and “Streamroller” CPUs, there’s an “oddity” with the “Seatlle” processor featuring up to 16 ARM Cortex A57 cores using ARMv8 64-Bit architecture. “Seattle” will come with either 8- or 16-core CPU with ARM Cortex-A57 cores clocked at 2GHz or greater, and is expected to offer 2 to 4 times the performance of AMD Opteron X-Series processors (x86 APU SoC) with improvement in compute-per-watt. “Seatlle” will handle up to 128GB DRAM, use offload engines for better power efficiency and reduced CPU loading, provides server caliber encryption, compression and legacy networking including integrated 10GbE. “Seattle” samples are expected to be available in Q1 2014, with production in H2 2014.

Rockchip RK3168 Powered Tablets Are Starting to Show Up for Sale

Rockchip first showcased a tablet prototype with RK3168 dual core processor at the Hong Kong Electronics Fair in April, showing lower power consumption compared to RK3066. At the time, tablets based on this processor were still in development, but this has changed as a few RK3168 tablets are now showing up in Aliexpress. Prices for 7″ Android tablets such as Cube U25GT PRO, are now about $110 as low as $75 including shipping, but this should come down as more sellers provide the devices. Cube U25GT PRO is an updated version of the U25GT pictured above. Here are the specifications of the PRO version: SoC – Rockchip RK3168 @ 1.2 GHz with PowerVR SGX540 GPU System Memory – 512 MB RAM Storage – 8GB NAND Flash + micro SD card slot Display – 7″ 5 point touch capacitive screen (1024×600) Camera – 0.3MP front camera Connectivity – Wifi 802.11b/g/n + […]

iPazzPort SY-20-19VC Android STB is also a Remote Control Charging Dock

iPazzPort SY-20-19VC, aka iPazzPort Pearl, is an Android 4.1.1 set-top box powered by Rockchip RK3066 that comes bundled with with a dual sided RF remote with a QWERTY keyboard, touch pad, and voice support. That’s pretty common these days. The design however, is somewhat original, as once you’re done watching videos or playing games, you can put back the remote into an opening in the set-top box to store it and recharge it, and it may prevent you from losing the remote under the pillows, and the remote will be fully charged most of the time. Here are the specifications of this media player: SoC – Rockchip RK3066 @ 1.6GHz + Mali-400 MP4 GPU System Memory – 1GB DDR3 Storage – 4GB + micro SD card slot (up to 32GB, or is it 16GB?) Connectivity 802.11b/g/n Wi-Fi 10/100M Ethernet 3G via external USB 3G dongle Video Output – HDMI 1.4 […]

Stealth Nighthawk F-117A is a Raspberry Pi-in-a-Stick Preloaded with XBMC

Stealth Nighthawk F-117A was a “single-seat, twin-engine stealth ground-attack aircraft formerly operated by the United States Air Force (USAF)”, but it’s now an HDMI dongle based on the same processor as the Raspberry Pi, namely Broadcom BCM2825, software compatible with the Raspberry Pi, and preloaded with an XBMC OS, which turns out to the Raspbmc. The main hardware differences with Raspberry Pi are that you lose Ethernet, composite output, and all headers used for hardware hacking, but you gain Wi-Fi, a casing, and an even smaller form factor. Here are the specifications of the device: SOC – Broadcom BCM2835 @ 700mhz with Video Core IV GPU/VPU System Memory – 512MB Storage – micro SD card slot (up to 32GB) USB – 1x USB 2.0 host port + micro USB port for power Video Output – HDMI (up to 1080p) Connectivity – Wi-Fi 802.11n Power – 5V/1A via microUSB port Dimensions – […]

This is How the BeagleBone Black is Manufactured

CircuitCo has recently uploaded an interesting “Make of the BeagleBone Black” video showing how the BeagleBone Black is manufactured in their facilities in Richardson, Texas, USA. The main steps are as follows: A machine applies solder paste to the PCB Pick and place components Reflow soldering for SMT components Hand placement of through hole components such as the Ethernet connector Selective soldering PCB washing Optical inspection via an automatic optical inspection (AOI) machine Manual inspection Burn-in tests after flashing the board with factory firmware Functional testing Packing and shipping Beside the overall process, one interesting point is that human hands are only involved with through-hole components placement, functional testing and packing & shipping. Even those steps may eventually be automatized in the future with robots such as Baxter. Watch the video, it’s worth a look.
