A researcher has broken the record for calculating the mathematical constant Pi, by using a number of computers running with Nvidia graphics cards. Ed Karrels of Santa Clara University used the GPUs in the graphics cards instead of normal computer processors in order to calculate pi to eight-quadrillion places.
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's is reportedly set to introduce a new flagship graphics card, which is said to carry the label GeForce GTX 590. Corroborating earlier leaks, the card will allegedly integrate dual GF110 GPUs with a combined 1024 CUDA cores and 3GB of memory, sources have told NordicHardware. The latest information suggests separate leak, which was tied to the name GTX 595, may have been an prototype of the 590.
NVIDIA today confirmed its second-ever GeForce 500 series chipset in a push to bring its new graphics to the mainstream. The GTX 570 has the exact same 480 cores as the old GTX 480 but, through the refined architecture, runs at a higher 732MHz main clock speed, 1.46GHz clock for each core and a 1.9GHz memory clock. It uses a narrower 320-bit memory interface (down from 384 bits) but, due to the combined improvements, has a higher texture fill rate bumped up from 42 billion to 43.9 billion pixels per second.
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.
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 today confirmed its rumored entry-level video chipset, the GeForce GT 430. The design is targeted at home theater computers and other systems where video playback support is more important than raw 3D performance and now supports HDMI with passthrough audio. It can output HDMI 1.4a for full 3D video along with Dolby TrueHD and DTS-HD Master Audio surround sound.
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's first mainstream GeForce 400 notebook chipset, the GT 425M, has surfaced in leaks earlier this month. Semi-Accurate noted that the graphics core has been listed as showing in a 17-inch ASUS notebook, but with different features. Some list it as only a DirectX 10 chip, implying that it's only a refreshed 300M chip, while others mention DirectX 11 and that it would use a version of the Fermi architecture in the GTX 480M.
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.

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
