  • AMD Launches Radeon R7 Series Solid State Drives With OCZ

    MojoKid (1002251) writes AMD is launching a new family of products today, but unless you follow the rumor mill closely, it's probably not something you'd expect. It's not a new CPU, APU, or GPU. Today, AMD is launching its first line of solid state drives (SSDs), targeted squarely at AMD enthusiasts. AMD is calling the new family of drives, the Radeon R7 Series SSD, similar to its popular mid-range line of graphics cards. The new Radeon R7 Series SSDs feature OCZ and Toshiba technology, but with a proprietary firmware geared towards write performance and high endurance. Open up one of AMD's new SSDs and you'll see OCZ's Indilinx Barefoot 3 M00 controller on board—the same controller used in the OCZ Vector 150, though it is clocked higher in these drives. That controller is paired to A19nm Toshiba MLC (Multi-Level Cell) NAND flash memory and a DDR3-1333MHz DRAM cache. The 120GB and 240GB drives sport 512MB of cache memory, while the 480GB model will be outfitted with 1GB. Interestingly enough, AMD Radeon R7 Series SSDs are some of the all-around, highest-performing SATA SSDs tested to date. IOPS performance is among the best seen in a consumer-class SSD, write throughput and access times are highly-competitive across the board, and the drive offered consistent performance regardless of the data type being transferred. Read performance is also strong, though not quite as stand-out as write performance.

  • Software Combines Thousands of Online Images Into One That Represents Them All

    Zothecula writes If you're trying to find out what the common features of tabby cats are, a Google image search will likely yield more results than you'd ever have the time or inclination to look over. New software created at the University of California, Berkeley, however, is designed to make such quests considerably easier. Known as AverageExplorer, it searches out thousands of images of a given subject, then amalgamates them into one composite "average" image.

  • Android Motorcycle Helmet/HUD Gains Funding

    DeviceGuru (1136715) writes Skully Systems has achieved Indiegogo funding for a high-tech Android 4.4 based motorcycle helmet with a head-up display (HUD), GPS navigation, and a 180-degree rearview camera. The Skully AR-1 helmet launched on Indiegogo on Aug. 10 and quickly blasted past its $250,000 flexible funding goal and has already surpassed $900,000 in funding. The helmet runs a heavily modified version of Android 4.4, with both screen size and safety in mind, according to Skully's Tow. 'You should not think of it as being Android as seen in a phone; it doesn't run the same skin,' wrote Tow on the Skully forum page. 'You instead should think of it as a variant of Linux, not Android per se. What counts is the device drivers, graphics rendering for our turn by turn directions and vehicle telemetry, etc. More nerdy things like communication over the I2C bus to the image processing module.' Helmets are available starting at $1,399, with shipments due in May 2015.

  • NVIDIA Tegra K1: First Mobile Chip With Hardware-Accelerated OpenCL

    New submitter shervinemami writes (starting with a pretty big disclaimer: "I'm an Engineer at NVIDIA.") The latest CompuBench GPU benchmarks show NVIDIA's Tegra K1 running whole OpenCL algorithms around 5x faster than any other mobile device, and individual instructions around 20x faster! This huge jump is because mobile companies have been saying they support OpenCL on mobile devices since early 2013, but what they don't mention is that they only have software API support, not hardware-accelerated OpenCL running faster on their GPUs than CPUs. Now that NVIDIA's Tegra-K1 chip has started shipping in devices and thus is available for full benchmarking, it is clearly the only mobile chip that actually gives you proper hardware-accelerated OpenCL (and CUDA of course!). The K1 is also what's in Google's Project Tango 3-D mapping tablet.

  • Enthusiast Opts For $2200 Laser Eye Surgery To Enhance Oculus Rift Experience

    An anonymous reader writes After 30 years of wearing glasses, one man says that the Oculus Rift virtual reality headset has prompted him to get laser eye surgery. With farsightedness and astigmatism, he says, "Never thought much about the laser surgery until the Rift, that's for sure." He has an appointment to get the $2200 surgery on the 13th of this month. "For me it is clear, my eyeglasses are like an obstacle for optimal VR experience," he said. He hopes the surgery will remove his need for glasses, which can be uncomfortable inside of the Rift, if they fit at all, and cause several issues such as scratched lenses and lower field of view. Oculus plans to make the consumer version of the Oculus Rift (aka CV1) more friendly to glasses wearers, "...we have a lot of great ideas for supporting glasses in the consumer version [of the Rift] (especially since a huge portion of the Oculus team wears glasses everyday!)" they noted in their Kickstarter.

  • Valve Discloses Source 2 Engine In Recent DOTA 2 Update

    MojoKid (1002251) writes News and rumors about Valve's upcoming Source 2 engine have been buzzing for months, but a recent update to DOTA 2 contains the most persuasive evidence yet that a major engine is in the works. After the last patch, the game now contains a number of programmed default paths, directories, and file names that didn't previously exist. Source-related DLLs and executables (engine.dll, vconsole.dll) have been updated to "engine2.dll" and vconsole2.dll." The tileset editor has a default Source path. There's also now an option to save files as "Source 1.0 Map Files" where no previous option existed. Here's the funny thing — while most people think of a game screenshot as the best evidence you can buy, low-level file directories, default trees, and changed application behavior is actually more persuasive. Source 1.0 was never updated to support DX11 or OpenGL 4.x, and while the engine can still be used for impressive titles, its DX9 limitations and ancient modding tools are showing their age. It's time to bring the game engine into the modern world, and hopefully these DOTA 2 updates mean that Valve is moving closer to that goal.

  • California Man Sues Sony Because Killzone: Shadowfall Isn't Really 1080

    Sonny Yatsen (603655) writes A California man with nothing better to do has launched a class-action lawsuit against Sony because he claims he was harmed because Killzone: Shadowfall's multiplayer mode doesn't have native 1080p resolution as Sony originally claimed. He now demands 'all economic, monetary, actual, consequential, statutory and compensatory damages' as well as punitive damages from Sony.

  • 2D To 3D Object Manipulation Software Lends Depth to Photographs

    Iddo Genuth (903542) writes "A group of students from Carnegie Mellon University and the University of California, Berkeley have developed free software which uses regular 2D images and combines them with free 3D models of objects to create unbelievable video results. The group of four students created the software (currently for Mac OS X only) that allows users to perform 3D manipulations, such as rotations, translations, scaling, deformation, and 3D copy-paste, to objects in photographs. However unlike many 3D object manipulation software, the team's approach seamlessly reveals hidden parts of objects in photographs, and produces plausible shadows and shading."

  • Digia Spinning Off Qt Division Into New Company

    An anonymous reader writes with news that, after a six year journey, Qt will once again be maintained by a standalone company. From the Digia weblog: ... Even though the open source project and the commercial side of Qt are highly dependent upon each other, they have over the last years drifted apart. ... Because of the separation between the open source and commercial offerings, we often end up competing against ourselves instead of competing against other technologies. ... We are now starting a conscious effort to overcome these problems. As you might have read, Digia has decided to move the Qt business into a company of its own. Thus we will soon have a company (owned by Digia), that will focus 100% on Qt. At the same time we would like to take the opportunity and retire qt.digia.com and merge it with the content from qt-project.org into a new unified web presence. The unified web page will give a broad overview of the Qt technology, both enterprise and open-source, from a technical, business and messaging perspective.

  • AMD Launches New Higher-End Kaveri APUs A10-7800 and A6-7400K

    MojoKid (1002251) writes "AMD updated its family of Kaveri-based A-Series APUs for desktop systems recently, namely the A10-7800 and the A6-7400K. The A10-7800 has 12 total compute cores, 4 CPU and 8 GPU cores, with average and maximum turbo clock speeds of 3.5GHz and 3.9GHz, respectively. The A6-7400K arrives with 6 total cores (2CPU, 4 GPU) and with the same clock frequencies. ... The AMD A10-7800 APU's performance is somewhat mixed, though it is a decent performer overall. Its Steamroller-based CPU cores do not do much to make up ground versus Intel's processors, so in the more CPU-bound workloads, Intel's dual-core Core i3-4330 competes favorably to AMD's quad-cores. And in terms of IPC and single-thread performance Intel maintains a big lead. Factor graphics into the equation, however, and the tides turn completely. The GCN-based graphics engine in Kaveri is a major step-up over the previous-gen, and much more powerful than Intel's mainstream offerings. The A10-7800's power consumption characteristics are also more desirable versus the Richland-based A10-6800K."

  • $299 Android Gaming Tablet Reviewed

    Vigile (99919) writes "Last week NVIDIA announced the SHIELD Tablet and SHIELD Controller, and reviews are finally appearing this morning. Based on the high performance Tegra K1 SoC that integrates 192 Kepler architecture CUDA cores, benchmarks reveal that that the SHIELD Tablet is basically unmatched by any other mobile device on the market when it comes to graphics performance — it is more than 2.5x the performance of the Apple A7 in some instances. With that power NVIDIA is able to showcase full OpenGL versions of games like Portal and Half-Life 2 running at 1080p locally on the 19:12 display or output to a TV in a "console mode." PC Perspective has impressions of that experience as well as using the NVIDIA Game Stream technology to play your PC games on the SHIELD Tablet and controller. To go even further down the rabbit hole, you can stream your PC games from your desktop to your tablet, output them to the TV in console mode, stream your game play to Twitch from the tablet while overlaying your image through the front facing camera AND record your sessions locally via ShadowPlay and using the Wi-Fi Direct powered controller to send and receive audio. It is incredibly impressive hardware but the question remains as to whether or not there is, or will be, a market for Android-based gaming devices, even those with the power and performance that NVIDIA has built."

  • NVIDIA Launches Tegra K1-Based SHIELD Tablet, Wireless Controller

    MojoKid (1002251) writes NVIDIA just officially announced the SHIELD Tablet (powered by their Tegra K1 SoC) and SHIELD wireless controller. As the SHIELD branding implies, the new SHIELD tablet and wireless controller builds upon the previously-released, Android-based SHIELD portable to bring a gaming-oriented tablet to consumers. The SHIELD Tablet and wireless controller are somewhat of mashup of the SHIELD portable and the Tegra Note 7, but featuring updated technology and better build materials. You could think of the SHIELD Tablet and wireless controller as an upgraded SHIELD portable gaming device, with the screen de-coupled from the controller. The device features NVIDIA's Tegra K1 SoC, paired to 2GB of RAM and an 8", full-HD IPS display, with a native resolution of 1920x1200. There are also a pair of 5MP cameras on the SHIELD Tablet (front and rear), 802.11a/b/g/n 2x2 MIMO WiFi configuration, GPS, a 9-axis motion sensor, and Bluetooth 4.0 LE. In addition to the WiFi-only version (which features 16GB of internal storage), NVIDIA has a 32GB version coming with LTE connectivity as well. NVIDIA will begin taking pre-orders for the SHIELD Tablet and wireless controller immediately.

  • Appeals Court Affirms Old Polaroid Patent Invalid

    mpicpp (3454017) writes with news of a notoriously abused (basically "method of displaying images on a machine") software patent being declared invalid. From the article: The ruling from last week is one of the first to apply new Supreme Court guidance about when ideas are too "abstract" to be patented. ... The patents in this case describe a type of "device profile" that allows digital images to be accurately displayed on different devices. US Patent No. 6,128,415 was originally filed by Polaroid in 1996. After a series of transfers, in 2012 the patent was sold to Digitech Image Technologies, a branch of Acacia Research Corporation, the largest publicly traded patent assertion company. ... In the opinion, a three-judge panel found that the device profile described in the patent is a "collection of intangible color and spatial information," not a machine or manufactured object. "Data in its ethereal, non-physical form is simply information that does not fall under any of the categories of eligible subject matter under section 101," wrote Circuit Judge Jimmie Reyna on behalf of the panel.

  • X.Org Server 1.16 Brings XWayland, GLAMOR, Systemd Integration

    An anonymous reader writes The much anticipated Xorg Server 1.16 release is now available. The X.Org "Marionberry Pie" release features XWayland integration, GLAMOR support, systemd support, and many other features. XWayland support allows for legacy X11 support in Wayland environments via GL acceleration, GLAMOR provides generic 2D acceleration, non-PCI GPU device improvements, and countless other changes. The systemd integration finally allows the X server to run without root privileges, something in the works for a very long time. The non-PCI device improvements mean System-on-a-Chip graphics will work more smoothly, auto-enumerating just like PCI graphics devices do. As covered previously, GLAMOR (the pure OpenGL acceleration backend) has seen quite a bit of improvement, and now works with Xephyr and XWayland.

  • KDE Releases Plasma 5

    KDE Community (3396057) writes "KDE proudly announces the immediate availability of Plasma 5.0, providing a visually updated core desktop experience that is easy to use and familiar to the user. Plasma 5.0 introduces a new major version of KDE's workspace offering. The new Breeze artwork concept introduces cleaner visuals and improved readability. Central work-flows have been streamlined, while well-known overarching interaction patterns are left intact. Plasma 5.0 improves support for high-DPI displays and ships a converged shell, able to switch between user experiences for different target devices. Changes under the hood include the migration to a new, fully hardware-accelerated graphics stack centered around an OpenGL(ES) scenegraph. Plasma is built using Qt 5 and Frameworks 5." sfcrazy reviewed the new desktop experience. It would appear the semantic desktop search features finally work even if you don't have an 8-core machine with an SSD.

  • AMD FirePro W9100 16GB Workstation GPU Put To the Test

    Dputiger (561114) writes "It has been almost two years since AMD launched the FirePro W9000 and kicked off a heated battle in the workstation GPU wars with NVIDIA. AMD recently released the powerful FirePro W9100, however, a new card based on the same Hawaii-class GPU as the desktop R9 290X, but aimed at the professional workstation market. The W9100's GPU features 2,816 stream processors, and the card boasts 320GB/s of memory bandwidth, and six mini-DisplayPorts, all of which support DP1.2 and 4K output. The W9100 carries more RAM than any other AMD GPU as well, a whopping 16GB of GDDR5 on a single card. Even NVIDIA's top-end Quadro K6000 tops out at 12GB, which means AMD sits in a class by itself in this area. In terms of performance, this review shows that the FirePro W9100 doesn't always outshine its competition, but its price/performance ratio keep it firmly in the running. But if AMD continues to improve its product mix and overall software support, it should close the gap even more in the pro GPU market in the next 18-24 months."

  • Nano-Pixels Hold Potential For Screens Far Denser Than Today's Best

    Zothecula (1870348) writes "The Retina displays featured on Apple's iPhone 4 and 5 models pack a pixel density of 326 ppi, with individual pixels measuring 78 micrometers. That might seem plenty good enough given the average human eye is unable to differentiate between the individual pixels, but scientists in the UK have now developed technology that could lead to extremely high-resolution displays that put such pixel densities to shame."

  • Watch Dogs Graphics and Gameplay: PC Vs. Xbox One, With Surprising Results

    MojoKid writes: Normally, the question of whether a game runs better on the PC or a console is a no-brainer, at least for PC users. Watch Dogs, however, with its problematic and taxing PC play, challenges that concept. And since the gap between consoles and PCs is typically smallest at the beginning of the console generation, HotHardware decided to take the Xbox One out for a head-to-head comparison against the PC with this long-awaited title. What was found may surprise you. Depending on just how much horsepower your PC has, the Xbox One (and possibly the PS4 though that wasn't compared) might be the better option. There's no question that the PC can look better, even before you factor in the mods that have been released to date, but unless you've spent $300 or more on a fairly recent GPU, you're not going to be able to run the game at sufficiently high detail to benefit from the enhanced image quality and resolution. If you have a Radeon HD 7950 / R9 280 or an NVIDIA card with greater than 4GB of RAM or a GeForce GTX 780 / 780 Ti, you can happily observe Watch Dogs make hash out of the Xbox One — but statistically, only a minority of gamers have this sort of high-end hardware. This comparison should be viewed in light of the recent allegations that the PC version's graphics were deliberately handicapped.
