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.
