NVIDIA formally brought its Kepler graphics core to the market Thursday, starting with its desktop line. The GeForce GTX 680 introduces new multiprocessing core groups known as SMX; they reportedly provide twice as much performance for the same energy as the GeForce 500 series. With three times as many cores as its ancestor (1,536), 2GB of 256-bit GDDR5 memory, and a 1GHz base clock, it's purportedly 43 percent faster in a game like Skyrim than AMD's Radeon HD 7970, even as it uses 28 percent less power.
NVIDIA's GeForce GTX 680 was spoiled in large fashion after a promo video was leaked (below) online. Product Marketing VP Ujesh Desai claims both that the GTX 680 is the fastest graphics card in the world along with introducing multiple new features. One, GPU Boost, would allow for dynamic overclocking: games and other 3D apps that underuse certain parts of the graphics could see their performance improve with higher frequencies.
NVIDIA overnight quietly brought out its first 500-series GeForce notebook graphics. The GeForce GT 540M like the GTX 580 is primarily a clock speed increase with an increase in its main and effects core clock speeds to 672MHz and 1.34GHz each. It shares the GeForce GT 435M's 96 cores and 128-bit memory bandwidth.
NVIDIA this morning released its cheapest ever graphics chipset based on its current Fermi core. The GeForce GTS 450 scales back to 192 effects cores and a 128-bit memory bus but is expected to be on par or faster than its arch-rival, AMD's Radeon HD 5750. It's pitched as an alternative to integrated graphics as a partial GF106 core is both cheaper and much more energy efficient than a full GF106 core or earlier designs.
NVIDIA today brought out its first more frugal GeForce 400 series chipset in the form of the GeForce GTX 460. The recently leaked hardware uses the new 40 nanometer, GF104 chipset and is actually in some areas faster than the GTX 465. It has fewer stream (visual rendering) processors, at 336 versus 352, but has more texture addresses at 56 compared to 44; it also has a faster clock speeds across the board with a 675MHz core, 1.35GHz shader (effect) clock speeds, and a 900MHz actual speed for its GDDR5 memory.
NVIDIA today started off its GeForce 400M notebook graphics line by launching the series' highest-end model. The GeForce GTX 480M has almost three times as many shader (effects) cores as the 285M it replaces at 352 and carries the hardware tessellation, cache and other changes that make it a generational leap. NVIDIA claims that the 480M can be as much as five times faster than ATI's Mobility Radeon 5000 series in graphics duties and 10 times faster encoding video when using technology like CUDA or OpenCL.
Developers at the Computer Human Interface conference and elsewhere this week have been showing new approaches to displays that could allow interaction with a perceived 3D environment. The pCube (video below) from the University of British Columbia is unique in depending on LCDs on each side to create a 3D perspective accurate from every angle. Besides letting users view an object from every angle, it has an accelerometer to respond to motion and sensors that respond to an in-air device to interact with the inside of the cube, although it doesn't yet support touch.
NVIDIA late yesterday put up a video (viewable below) that provides some of the first official performance indicators for the GeForce GTX 480. In a synthetic test of Uniengine, a 3D engine that supports DirectX 11 (OpenGL 3.2) features, the GTX 480 was tied in maximum frame rates with the ATI Radeon HD 5870 but is much faster under high stress, often producing over 40 frames per second where the AMD-made rival produces a noticeably choppier 20. The test isn't necessarily reflective of real gameplay, and is the same demo Electronista saw at CES, but shows the card likely being faster for games that use techniques like tessellation to dynamically add detail.
NVIDIA will officially launch the GeForce GTX480 and GTX470 graphics cards next month at the upcoming PAX East gaming conference, according to a Twitter post. The components are the first to integrate the company's Fermi architecture. The technology is said to improve graphics performance while expanding support for other standards such as OpenCL and PhysX
NVIDIA in a Twitter update has confirmed the names of the first two graphics chips based on its Fermi architecture. The GeForce GTX 470 and 480 should be the first to ship. Details of their performance weren't given, but the naming scheme positions them as top-end parts for gamers.

Cirrus creates Lightning-headphone dev kit
Apple supplier Cirrus Logic has introduced a MFi-compliant new development kit for companies interested in using Cirrus' chips to create Lightning-based headphones, which -- regardless of whether rumors about Apple dropping the analog headphone jack in its iPhone this fall -- can offer advantages to music-loving iOS device users. The kit mentions some of the advantages of an all-digital headset or headphone connector, including higher-bitrate support, a more customizable experience, and support for power and data transfer into headphone hardware. Several companies already make Lightning headphones, and Apple has supported the concept since June 2014. http://bit.ly/29giiZj
Apple Store app offers Procreate Pocket
The Apple Store app for iPhone, which periodically rewards users with free app gifts, is now offering the iPhone "Pocket" version of drawing app Procreate for those who have the free Apple Store app until July 28. Users who have redeemed the offer by navigating to the "Stores" tab of the app and swiping past the "iPhone Upgrade Program" banner to the "Procreate" banner have noted that only the limited Pocket (iPhone) version of the app is available free, even if the Apple Store app is installed and the offer redeemed on an iPad. The Pocket version currently sells for $3 on the iOS App Store. [32.4MB]
Porsche adds CarPlay to 2017 Panamera
Porsche has added a fifth model of vehicle to its CarPlay-supported lineup, announcing that the 2017 Panamera -- which will arrive in the US in January -- will include Apple's infotainment technology, and be seen on a giant 12.3-inch touchscreen as part of an all-new Porsche Communication Management system. The luxury sedan starts at $99,900 for the 4S model, and scales up to the Panamera Turbo, which sells for $146,900. Other vehicles that currently support CarPlay include the 2016 911 and the 2017 models of Macan, 718 Boxster, and 718 Cayman. The company did not mention support for Google's corresponding Android Auto in its announcement. http://bit.ly/295ZQ94
Apple employees testing wheelchair features
New features included in the forthcoming watchOS 3 are being tested by Apple retail store employees, including a new activity-tracking feature that has been designed with wheelchair users in mind. The move is slightly unusual in that, while retail employees have previously been used to test pre-release versions of OS X and iOS, this marks the first time they've been included in the otherwise developer-only watchOS betas. The company is said to have gone to great lengths to modify the activity tracker for wheelchair users, including changing the "time to stand" notification to "time to roll" and including two wheelchair-centric workout apps. http://bit.ly/2955JDa

Apple's third-quarter results due July 26
Apple has advised it will be issuing its third-quarter results on July 26, with a conference call to answer investor and analyst queries about the earnings set to take place later that day. The stream of the call will go live at 2pm PT (5pm ET) via Apple's investor site, with the results themselves expected to be released roughly 30 minutes before the call commences. Apple's guidance for the quarter put revenue at between $41 billion and $43 billion. http://apple.co/1oi1Pbm
Twitter stickers slowly roll out to users
Twitter has introduced "stickers," allowing users to add extra graphical elements to their photos before uploading them to the micro-blogging service. A library of hundreds of accessories, props, and emoji will be available to use as stickers, which can be resized, rotated, and placed anywhere on the photograph. Images with stickers will also become searchable with viewers able to select a sticker to see how others use the same graphic in their own posts. Twitter advises stickers will be rolling out to users over the next few weeks, and will work on both the mobile apps and through the browser. http://bit.ly/29bbwUE
