NVIDIA GeForce GTX 570 official at mid-range
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.
The design is targeted at AMD's soon to be replaced Radeon HD 5870 and allegedly beats it by a wide margin. Adding hardware tessellation units gives it as much as a 128 percent boost in DirectX 11-capable games like HAWX 2 due to the lack of tessellation support in AMD's graphics, but performance in games without hardware tessellation is still up to 30 percent faster in StarCraft II. Separate tests from Anandtech show the gap narrowing, however.
Common NVIDIA features persist, such as 3DTV Play, 3D Vision Surround and SLI multi-card setups; it supports OpenGL 4.1 as well as general-purpose computing tasks like CUDA and OpenCL. Reference boards have dual dual-link DVI ports and HDMI out with audio passthrough.
Boards are available today from ASUS, EVGA, Gigabyte, MSI and other third parties. Prices are significantly higher than the $250 Radeon HD 5870, but at $350 run considerably lower than the $500 of the GTX 580. Companies making pre-assembled computers are also starting to use the GTX 570 immediately, including CyberPower.
