Closer look at NVIDIA Shield TV with Google Assistant and SmartThings Link

October 1st, 2017 No comments

The NVIDIA Shield TV may be a few years old at this point, but it’s still one of the most powerful Android TV boxes on the market… and it keeps getting more versatile.

Today NVIDIA rolled out software version 6.0, which brings support for Google Assistant and the option to plug in a SmartThings Link dongle to turn the TV box into a home automation hub.

I got a chance to check out a Shield TV running the latest software, and while it was a bit too noisy to really test the Google Assistant feature, I got an overview of how it works.

The Shield currently comes in a few configurations: for $179 you can get a Shield TV with just a multimedia remote. Or for $199 you can get a model with both a multimedia remote and a game controller.

The remote has a microphone button that you can press to issue voice commands, and now that Assistant is baked-in, that means you can get news and weather updates, check sports scores, ask questions, and of course, control media playback.

“Play Game of Thrones” will play the HBO show. “Pause” will pause. And “turn off” will power down the system, among other things.

If you have the game controller, you also have the option of enabling always-listening support so that you don’t have to press a button. You can just say “OK Google” when you’re near the controller to issue commands just like you would with a phone or Google Home device.

NVIDIA says the gamepad gets up to 2 weeks of battery life in standby if always-listening is enabled, and up to a month if it’s not. Of course, if you actually play games you’ll probably need to charge it a bit more often than that.

As for the SmartThings USB dongle, it adds support for smart home products that use Z-Wave or Zigbee protocols, and all the hardware is in the USB stick itself, which means that you can add the functionality to a Shield TV for as little as $15 (that’s the pre-order price, but the full list price is $40).

Since the stick is kind of wide, it also comes with a short USB extension cord so that you can plug it into the Shield TV without blocking the device’s other ports.

Once connected, you can use the SmartThings Link to connect to devices including smart light bulbs, thermostats, and home security systems, receive alerts on your Shield TV, monitor everything using a SmartTHings app for iOS or Android, and use Google Assistant for voice commands.

You can also automate tasks such as turning on the lights or locking the doors at certain times, and you can set routines that let you do things like turn on the lights and start the coffee maker when you say “good morning.”

Intel’s low-power “Gemini Lake” chips coming in October/November?

October 1st, 2017 No comments

Intel may be preparing to launch its third set of processors in the span of just a few months.

According to a leaked product roadmap published by Gamers Nexus, Intel’s low-power Gemini Lake chips will be introduced in late October or early November.

They’ll join the recently launched Kaby Lake Refresh line of chips for laptops and Coffee Lake-S processors for desktops.

Gemini Lake chips are expected to include dual-core and quad-core processors that will be sold under the Celeron and Pentium Silver brands.

While Intel will likely offer models with 6 watt Gemini Lake chips for use in laptops and convertible tablets, the roadmap in question only seems to focus on the desktop variants, which are 10 watt chips that will include the Celeron J4005, J4105, and Pentium J5005 processors.

These will be the follow-up to Intel’s curent-gen “Apollo Lake” processors and, among other things, they’re expected offer up to 15 percent better performance, more cache memory, and native support for HDMI 2.0.

Intel is also expected to launch a second round of Coffee-Lake S chips in the first quarter of 2018. These will include 35 watt and 65 watt chips with between 2 and 6 CPU cores and support for the Intel 300 Series chipset.

Mecool VS-RK3399 Board Linux Benchmarks

September 29th, 2017 No comments

We already have plenty of benchmarks for Rockchip RK3399 in Android, so instead I started by installing the latest Phoronix Test Suite in Debian:

… and ran the tests I did on NanoPi NEO 2 earlier:

For whatever reasons OpenSSL and Mafft failed to download, but we still have the other benchmarks to compare with. Note that the Debian image is likely not optimized, and while the system runs an Aarch64 kernel, the rootfs is only 32-bit, which may have affected some of the benchmarks.

But let’s see what’s we’ve got, starting with John the Ripper password cracker, a multi-threaded benchmark.

Click to Enlarge

We’d normally expect hardware platforms based on Rockchip RK3399 SoC to outperform all other Cortex A53 or A17 based boards in the list, but MiQi board with a quad core Cortex A17 processor @ 1.8 GHz, and BPI-M3 board with an octa-core Cortex A7 processor @ 2.0 GHz, both beat the VS-RK3399 with an hexa-core processor with two Cortex A72 cores @ 1.8 GHz, and four Cortex A53 cores @ 1.4 GHz. BPI-M3 is even twice as fast in this test.

C-Ray is also a multi-threaded benchmark, but here Rockchip RK3399 SoC shines, making VS-RK3399 the fastest platform of the lot, also beating MeLE PCG02U TV stick (MeUbuntu 14.04.3) powered by an Intel Bay Trail Z3735F processor.

Smallpt is another multi-threaded benchmark, and VS-RK3399 board does well, but it’s still beaten by the Intel TV stick (OpenMP might help here?), and Banana Pi M3.

The Rockchip RK3399 board is the fastest ARM platform for Himeno linear solver of pressure Poisson, but due to specific x86 instructions and/or optimization, the Bay Trail TV stick is well ahead.

Finally, for FLAC audio encoding, VS-RK3399 is the best ARM platform (in the tested lot) by a wide margin, but Intel is ahead with their more advanced SIMD instructions.

So Rockchip RK3399 processor will outperform all ARM boards with single threaded tasks thanks to it Cortex A72 cores, but in some multi-threaded tests, octa-core Cortex A7, and quad core Cortex A17 platforms may deliver better results.

VS-RD-RK3399 board comes with a 32GB Samsung eMMC 5.0 flash that supposed to deliver 246/46 MB/s R/W speed, and 6K/5K R/W IOPS.

I tested it with iozone using a 100MB file:

Results for the read speed are around the theoretical limit, but write speeds are well above, maybe because of some caching.

I switched to Gigabit Ethernet performance testing starting with a full duplex iperf test:

Not quite optimal, so let’s look at upload only:

and download only:

Both of which are quite good. I had been told that IRQ may all be handled by CPU0 (Cortex A53 core in the board), and the following changes may improve performance:

So I repeated the tests, and something impossible happened:

We’re not supposed to get 1.35 Gbps on Gigabit Ethernet… So I tried again for a longer period of time (10 minutes):

Same results.. But looking at the output from the server side, it looks more realistic:

and it does improve a little compared to the first test without the tweaks.

Rock960 Board is a 96Boards Compliant Board Powered by Rockchip RK3399 SoC

September 29th, 2017 No comments

So it looks like Rockchip is soon going to join 96Boards family with Rock960 board. Developed by a Guangzhou based startup called Varms, the board will be powered by Rockchip RK3399 hexa-core SoC, and comply with 96Boards CE specifications.

Rock960 board preliminary specifications:

  • SoC – Rochchip RK3399 hexa-core big.LITTLE processor with two ARM Cortex A72 cores up to 1.8/2.0 GHz, four Cortex A53 cores @ 1.4 GHz, and  ARM Mali-T860 MP4 GPU with OpenGL ES 1.1 to 3.2 support, OpenVG1.1, OpenCL 1.2 and DX 11 support
  • System Memory – 2 or 4GB RAM
  • Storage – 16 or 32GB eMMC flash + micro SD card
  • Video Output – 1x HDMI 2.0 up to 4K@60 Hz with CEC and HDCP
  • Connectivity – WiFi 802.11ac 2×2 MIMO up to 867 Mbps, and Bluetooth 4.1 LE (AP6356S module) with two on-board antennas, two u.FL antenna connectors
  • USB – 1x USB 2.0 host port, 1x USB 3.0 port, 1x USB 3.0 type C port with DP 1.2 support
  • Expansion
    • 1x 40 pin low speed expansion connector – UART, SPI, I2C, GPIO, I2S
    • 1x 60 pin high speed expansion connector – MIPI DSI, USB, MIPI CSI, HSIC, SDIO
    • 1x M.2 key M PCIe connector with support for up to 4-lane PCIe 2.1 (max bandwidth: 2.0 GB)
  • Misc – Power & u-boot buttons. 6 LEDS (4x user, 1x Wifi, 1x Bluetooth)
  • Power Supply – 8 to 18V DC input (12V typical) as per 96Boards CE specs; Battery header
  • Dimensions – 85 x 54 mm (96Boards CE form factor)

The board will support Android (AOSP), Ubuntu, the Yocto Project, and Armbian. The website shows the word “official” for the first three, and lists Canonical as partner. The company will also offer various at least one expansion board, and starter kit based on Seeed Studio Grove system with a mezzanine board with plenty of Grove headers, an LCD display, and various Grove modules like buzzers, relays, buttons, LEDs, temperature sensors, and so on.

Rock960 is both simpler and smaller than other RK3399 boards such as Firefly-RK3399 and VS-RK3399, so I’d expect it to be cheaper, hopefully below $100, once it becomes available. The website is still very much under construction, but you may find few more details there.
