Tagged: Raspberry Pi 2 Model B
Linux.com have just released benchmarks of the new Raspberry Pi 2 Model B with its improved processor and RAM. Benchmarking a Pi is always interesting as you must find applications which are reasonable for this device to use, with webserver software being a decent choice to compare to ODroid-U2, Radxa and the Beaglebone Black. openSSL 1.0.1e,DES and AES cbc mode ciphering and Blowfish were all tested with the Pi performing slowly but improved from the previous generation and certainly decent for a $35 piece of hardware. In addition both a full KDE desktop and KDE/Openbox were successfully installed with Openbox the recommended choice. Get all the results right here.
"Released in February, the Raspberry Pi Model 2 B is an update to the original board that brings quad cores for six times the performance of the original, 1 gigabyte of RAM for twice the memory, and still maintains backwards compatibility. The many CPU cores are brought about by moving from the BCM2835 SoC to the BCM2836 SoC in the Raspberry Pi 2."

As GDC progresses here in San Francisco, AMD took the wraps off of a new SDK for game developers to use to improve experiences with virtual reality (VR) headsets. Called LiquidVR, the goal is provide a smooth and stutter free VR experience that is universal across all headset hardware and to keep the wearer, be it a gamer or professional user, immersed.
AMD's CTO of Graphics, Raja Koduri spoke with us about the three primary tenets of the LiquidVR initiative. The 'three Cs' as it is being called are Comfort, Compatibility and Compelling Content. Ignoring the fact that we have four C's in that phrase, the premise is straight forward. Comfortable use of VR means there is little to no issues with neusea and that can be fixed with ultra-low latency between motion (of your head) and photons (hitting your eyes). For compatibility, AMD would like to assure that all VR headsets are treated equally and all provide the best experience. Oculus, HTC and others should operate in a simple, plug-and-play style. Finally, the content story is easy to grasp with a focus on solid games and software to utilize VR but AMD also wants to ensure that the rendering is scalable across different hardware and multiple GPUs.
To address these tenets AMD has built four technologies into LiquidVR: late data latching, asynchronous shaders, affinity multi-GPU, and direct-to-display.
The idea behind late data latching is to get the absolute most recent raw data from the VR engine to the users eyes. This means that rather than asking for the head position of a gamer at the beginning of a render job, LiquidVR will allow the game to ask for it at the end of the rendering pipeline, which might seem counter-intuitive. Late latch means the users head movement is tracked until the end of the frame render rather until just the beginning, saving potentially 5-10ms of delay.

The Shuttle DS57U is a new small form factor fanless PC packing Intel’s latest Broadwell processor. The Shuttle 1.3L chassis (7.9" x 6.5" x 1.5") is all black and sits vetically on raised feet. Vents run along the top of the case and the vertical design along with a large heatsink lets them offer a fanless design.
External I/O includes:
- 2 x USB 3.0
- 4 x USB 2.0
- 2 x RS232
- 1 x DisplayPort
- 1 x HDMI
- 2 x Analog audio
- 1 x SD card reader
- 2 x Gigabit Ethernet (Intel i211 and i218LM)
The PC can be attached to the back of a monitor stand or to the wall using its VESA mounting holes.
Internally, the Shuttle DS57U comes with up to an Intel Core i7 5500U processor which is a 15W dual core part with Hyper Threading clocked at 2.4GHz base and 3GHz max turbo, 4MB cache, and Intel 5500 graphics clocked at up to 950MHz. It is a barebones PC which means that users have to add their own storage, memory, and operating system. Users can add two laptop DDR3 SODIMMs (16GB max), a single 2.5” drive, and a two Mini PCI-e devices (an 802.11n wireless module comes pre-installed in the half-height slot).
The Shuttle DS57U would make for a silent home PC, media server, or an extremely overpowered home router (heh). Its feature set also makes the DS57U suited for commercial and industrial applications. The fanless Broadwell PC is available now in Europe for 192 euros (approximately $220 USD). There is no word on when it will hit this side of the pond, but its introduction is a promising start to other fanless Broadwell systems hitting the market.

Syber, a new division of CyberPowerPC, announced plans to launch a slew of Steam OS-powered living room PCs this fall. There are six Steam Machines planned in all, with prototypes being shown off at the Games Developer Conference (GDC) this week.
So far, CyberPowerPC has revealed the Syber Steam Machine-E, Syber Steam Machine-P, and Syber Steam Machine-K. At the low end sits the Steam Machine-E with an unspecified quad core AMD processor and NVIDIA GTX graphics card starting at $449. For $100 more, you can step up to the Steam Machine-P with a dual core Intel Pentium G3258 CPU clocked at 3.2GHz and an AMD Radeon R9 270X. Finally, the Steam Machine-K sits at the high end with an Intel Core i5-4690K processor and a NVIDIA Geforce GTX 970.
Syber also hinted at an exclusive orange clad Steam Machine through CyberPowerPC for $1,399.
Of course, these are merely starting prices and users will be able to further customize them when ordering. This is CyberPowerPC’s second stab at breaking into the living room with the SteamOS partnership. Interestingly, they have managed to shave a bit off the cost of the lowest end model and added several more tiers compared to the initial series launched at last year’s CES.
