Imagination Technologies outlined some plans for its far and near futures after Electronista stopped by its Mobile World Congress booth on Monday. The PowerVR developer showed a demo of a real-time raytracing graphics engine, where an app calculates the paths of individual light beams in a scene, that it expects to reach mobile devices. As shown in a demo running on a Mac, it could use surface properties rather than unchanging textures to generate the chrome effect on a car, even reflecting another car which in turn had a reflection of the sky.
NVIDIA took a major step towards spurring growth of its CUDA general-purpose code technology for video cards on Tuesday by posting the CUDA source code. Developers and education now have access to a variant on the LLVM compiler that will let them add new processor types and languages. The extension could see CUDA run on AMD's Radeon hardware, Intel's integrated graphics, and even use relatively old code like Fortran.
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.
AMD tonight kicked off the launch of a new graphics core generation by launching the Radeon HD 6850 and 6870. The designs are roughly on par with the performance of the outgoing 5850 but, through a new architecture, are considerably cheaper at $179 (6850) and $239 (6870) while still being more power efficient, particularly at idle. The chip designer claims a performance edge of as much as 30 percent over the GeForce GTX 460; the move has already forced NVIDIA to drop the GTX 460's average price to $199 to compete.
A US patent filing published today has raised concerns as it could give Microsoft control of hardware-accelerated video encoding. A continuance of an application for "accelerated video encoding using a graphics processing unit" would cover the common technique of calculating motion for video processing with the video chipset in a computer rather than the regular, usually slower main CPU. Its techniques are broad and cover tricks like turning each frame into macroblocks to process them in parallel.
NVIDIA chief Jen-Hsun Huang today at its GPU Technology Conference said his company would bring its CUDA general-purpose computing language directly to x86 chips. The approach developed with the Portland Group will let systems without NVIDIA cards handle the code. It will work best with multi-core processors and is seen as ideal for servers.
NVIDIA at PAX East tonight finally released the first video chipsets based on its Fermi architecture. The top-end GeForce GTX 480 leads the group and is billed as the "fastest GPU in the world:" it has 480 visual processing cores, 16 geometry units and four raster units that combined should beat the ATI Radeon HD 5800 series in real-world tests. It also has major optimizations to multi-card SLI that produce a 90 percent speed boost with a second card, making the case for multiple GeForce 400 series cards in high-end systems.
AMD this morning launched its second new video chipset in just a matter of days and this time targeted a comparatively untapped mini PC category. The Radeon HD 5570 is a major step up in performance from the 5450 with 400 stream processors versus 80 but still occupies a single card slot and is relatively short, making it ideal for small form factor cases where even the 5600 series would be too large or use too much power.
The just-unveiled Fermi graphics architecture will find its way into Macs and play an important role in Mac OS X Snow Leopard, NVIDIA chief scientist Bill Dally said today. While it's expected that NVIDIA would continue to play an important part of future Macs, the researcher drew a particular connection between the new GPU design and Apple's new OS, expecting that it would provide a significant boost for those apps that implement OpenCL. Windows 7 will also get support through DirectX 11 and DirectCompute.

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
SanDisk reveals two 256GB microSDXC cards
SanDisk has introduced two 256GB microSDXC cards. Arriving in August for $150, the Ultra microSDXC UHS-I Premium Edition card offers transfer speeds of up to 95MB/s for reading data. The Extreme microSDXC UHS-I card can read at a fast 100MB/s and write at up to 90MB/s, and will be shipping sometime in the fourth quarter for $200. http://bit.ly/294Q1If
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
