NVIDIA GeForce GTX 280 and GTX 260 Unleashed
Posted by newsbot on June 16th 2008



=93The high-end 280 card is powered by NVIDIA's 1.4 billion transistor GT200GPU, produced on TSMC's 65nm process node and is the largest, most complexchip TSMC has ever manufactured. Beyond just a larger number of streamprocessing units, the GT200 also supports three times the number of threadsin flight, as NVIDIA's previous G80, at any given time. It also has a newscheduler design that is up to 20% more efficient, along with a wider512-bit memory interface with improved z-cull and compression technology.Perhaps what's most interesting about this GPU however, are its twooperational states, one as a 3D Graphics processor and another standardcompute mode configuration. NVIDIA's new behemoth chip not only lights upthe gaming benchmarks but also can be specifically reprogrammed for moreefficient general purpose GPU (GPGPU) computing usage models like Foldingand supports atomic read-modify-write operations in memory.=94
