NVIDIA has shaken up its GeForce graphics card lineup, rebranding two budget-priced OEM GT 500-series cards from the Fermi-era architecture into 600-series examples. The GT 520 will now be known as the GT 620 while the GT 510 becomes the GT 605. Other than the name change, there are some slight hardware changes, though mostly not for the better.
NVIDIA in a quick video teaser (below) gave a hint of the GeForce GTX 590 along with its release date. The company wouldn't give direct clues other than that it's the highest-performing graphics chipset yet, but it did show Crysis 2 running smoothly in the background as a likely sign of how well it would run. The project was two years in the making, NVIDIA's Tom Peterson said.
NVIDIA pushed its second-generation Fermi graphics architecture further into the budget realm on Tuesday through the GeForce GTX 550 Ti. Its card costs just $150 and drops below the $250 of the GTX 560 Ti by cutting back on its parallelism It uses 192 processing cores versus the higher-end chipset's 384, a reduced 192-bit memory bus (versus 256-bit) and has half the texture addressing units at 32, although it partly compensates with a higher 900MHz main clock and faster 1.8GHz GDDR5 memory.
Lenovo's PC updates on Tuesday were headlined by two IdeaPad notebooks that claim to be more responsive than even the MacBook Air. The 14-inch Y470, as well as the 15.6-inch Y570 and Y570d, each have the option of a 32GB or 64GB SSD for the OS alongside a regular hard drive. Along with Intel's new Sandy Bridge processors and optimizations to the boot process, they can start in as little as 10 seconds, versus Apple's 15 seconds, while still holding as much as 1TB of regular space.
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.
Video card maker Palit late today spoiled NVIDIA's plans for its next 500-series graphics chipset with details given out days ahead of launch. Sales sheets sent out early have shown the GeForce GTX 570, a more mainstream alternative to the GTX 580, that would potentially outperform the older GTX 480 flagship while still costing less. The design would have a lower 1.28GB of RAM and a narrower 320-bit bus, according to Kitguru's copy, but would boost the main clock speed from 700MHz to 732MHz while also using faster individual shaders and video memory.
The first dual-chip GeForce 500 graphics card from NVIDIA has been spotted in photos online. The card is said to be the GeForce GTX 595, a high-end, single-board card with two Fermi GPUs. While tech specs are still relatively scarce, it's believed on enet it will have 3GB of total memory split between the two processors.
NVIDIA today brought its Fermi graphics architecture to the Mac at last by launching the Quadro 4000 for Mac. The workstation-class video supports the same features as its Windows counterpart and focuses heavily on general-purpose computing. It gives a lift to OpenCL in Snow Leopard and can greatly accelerate apps that are using NVIDIA's own CUDA language as well, such as video processing in Adobe Premiere Pro CS5.
NVIDIA today at last confirmed the existence of the GeForce GTX 580, its new graphics leader. The design jumps from 480 processing cores to 512 and adds 16 PolyMorph (hardware geometry tessellation) units that significantly boost the performance, especially when they can be fully used in DirectX 11 and OpenGL 4.1. In extreme cases, a GTX 580 can be up to 160 percent faster than a Radeon HD 5870 in a game like HAWX 2 and 62 percent faster in a DX9/DX10 game like StarCraft II.
