NVIDIA GeForce 600 Kepler graphics official
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.
GeForce GTX 680 features spoiled in official clip
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 GeForce GT 540M ramps up notebook video
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 unveils GeForce GTS 450 entry video
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 puts out GTX 460 at ideal price
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 claims GTX 480M wins mobile speed crown
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.
pCube and Holocube promise 3D displays
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 GTX 480 would run faster overall
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.
Company's first Fermi-based GPUs
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 skips to GeForce 400 for Fermi GPUs
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.
GeForce 300M uses 40nm, more shaders
Although it outlined some products at CES, NVIDIA has now formally detailed its GeForce 300M graphics line. The new series still uses a DirectX 10-level (OpenGL 2.1) architecture but is more efficient, in some cases using as many as 50 percent more shader (visual effect) cores. The series continues to provide full hardware video decoding and supports general-purpose computing like CUDA and OpenCL.
EVGA first to combine graphics, physics GPUs
EVGA has released a new hybrid card, the Hybrid GTX 275 Co-op PhysX, which uses NVIDIA's GTX 275 and GTS 250 GPUs on the same card. The two split tasks accordingly, with the GTX 275 taking care of the graphics while the GTS 250 does PhysX computing for physics in games like Batman: Arkham Asylum (included in the box) or Mirror's Edge. There is 1.28GB of combined memory while the GTS 250 and GTX 275 chips run at 633MHz and 738MHz, respectively. Total memory bandwidth tops out at 179.8GBps.
ASUS G50 and G71 ship
ASUS has announced it is now shipping its new gaming notebooks, the 15.4- or 15.6-inch G50 and 17-inch G71 that can be equipped with Intel's Core 2 Extreme quad-core mobile CPU. Both use NVIDIA's GeForce 9700M GT GPU with a dedicated 512MB of memory for not only graphics processing but other time-intensive computational tasks such as converting videos into other formats. The GPUs include support for technologies such as NVIDIA PhysX and other video acceleration and image-processing capabilities. Software drivers for NVIDIA PhysX and CUDA technologies will be offered as free downloads over the next few months.
NVIDIA GeForce Power Pack
NVIDIA on Tuesday gave its existing customers a bonus through the GeForce Power Pack, a new set of drivers that expose new features to certain GeForce cards. The upgrade takes advantage of the more universal nature of the effects processing cores in GeForce 8-, 9- and GTX-series cards to drive tasks that would normally depend on the main CPU. All these cards can now speed up physics in games and other apps that support PhysX; in specially enabled game maps with the new physics turned on, a mid-range GeForce 9800 GTX+ is nearly three times faster than the ATI Radeon HD 4850 that NVIDIA hopes to beat.
NVIDIA GeForce GTX coming?
NVIDIA plans on refreshing its GPU line-up next month with two new graphics card that will feature its next-generation CUDA-enabled graphics core, codenamed D10U. The company is expected to deliver both the GeForce GTX 260 (D10U-20) and GeForce GTX 280 (D10U-30) on June 18th as part of its summer refresh, according to DailyTech. The report claims that the GTX 260 will be a "significantly" scaled down version of the GTX 280, which will enable all 240 unified stream processors designed into the processor. These second-generation unified shaders perform 50 percent better than the shaders than its previous-generation offering, the company claims in its documentation; however, the new NVIDIA cards will only support GDDR3 memory and DirectX 10, while AMD focuses on faster GDDR5-based cards due early this summer.
Nvidia to acquire Ageia
Nvidia today announced an official acquisition of Ageia Technologies, the company behind the PhysX software and hardware components. The acquisition will give Nvidia a physics element for its Cuda parallel processing systems. The PhysX technology is currently in use in many Xbox 360, Playstation 3 and Nintendo Wii games, as well as many gaming PCs worldwide. Nvidia will be hosting a quarterly conference call on February 13th to provide more information about the acquisition in its final stages.
