The new 40nm GPUs feature the new PureVideo HD VP4 decoder hardware in them, as the older GeForce 8 and 9 GPUs only have PureVideo HD VP2 or VP3 (G98). Nvidia officially announced and released the GeForce GT 240 (GT215 GPU) on November 17, 2009. Nvidia officially announced and released the retail version of the previously OEM only GeForce 210 (GT218 GPU) and GeForce GT 220 (GT216 GPU) on October 12, 2009. The Ampere GA100 is currently the largest commercial GPU ever fabricated at 826 mm 2 with 54.2 billion transistors. It is larger than even the Kepler-based GK210 GPU used in the Tesla K80, which has 7.1 billion transistors on a 561 mm 2 die manufactured in 28 nm. The GeForce 400 Series have since superseded the GT200 chips in transistor count, but the original GT200 dies still exceed the GF100 die size.

It is the fifth largest CMOS-logic chip that has been fabricated at the TSMC foundry. GT200 GPUs also have improved performance in geometry shading.Īs of August 2018, the GT200 is the seventh largest commercial GPU ever constructed, consisting of 1.4 billion transistors covering a 576 mm 2 die surface area built on a 65 nm process. The GeForce 200 series GPUs (GT200a/b GPU), excluding GeForce GTS 250, GTS 240 GPUs (these are older G92b GPUs), have double precision support for use in GPGPU applications. Effectively, there were two GTX 260 cards in production with non-trivial performance differences. In late 2008, Nvidia re-released the GTX 260 with 216 stream processors, up from 192. Those that fail to meet the GTX 280 hardware specification are re-tested and binned as GTX 260 (which is specified with fewer stream processors, less ROPs and a narrower memory bus). During the manufacturing process, GTX chips were binned and separated through defect testing of the core's logic functionality.

The GeForce GTX 280 and GTX 260 are based on the same processor core. The GeForce 200 Series introduced Nvidia's second generation of Tesla (microarchitecture), Nvidia's unified shader architecture the first major update to it since introduced with the GeForce 8 Series.
