The GeForce 200 Series is the 10th generation of Nvidia's GeForce graphics processing units, which serves as the introduction for the Tesla architecture (GT-codenamed chips), named after the Serbian inventor and physicist Nikola Tesla.

Overview [edit]

The Geforce 200 Series introduces Nvidia's second generation unified shader architecture, the first major update to the company's original unified shader architecture used in the GeForce 8 Series.

The GeForce GTX 280 and GTX 260 are based on the same processor core. During the manufacturing process, GTX chips are binned and separated through defect testing of the core's logic functionality. 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).

In late 2008, Nvidia re-released the GTX 260 with 216 stream processors, up from 192. Effectively, there are two GTX 260 cards in production with non-trivial performance differences.

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. GT200 GPUs also have improved performance in geometry shading.

As of June 2008, the GT200 is the largest commercial GPU ever constructed. It consists of 1.4 billion transistors covering a 576 mm2 die surface area built on a 65 nm process. To date, the GT200 is the largest CMOS-logic chip that has been fabricated at the TSMC foundry. The GeForce 400 Series have since superseded the GT200 chips in transistor count, but the original GT200 dies still exceed the GF100 die size.

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. Nvidia officially announced and released the GeForce GT 240 (GT215 GPU) on November 17, 2009. The new 40nm GPUs feature the new PureVideo HD VP4 decoder hardware in them, the older GeForce 8 and 9 GPUs only have PureVideo HD VP2 or VP3(G98). They also support Compute Capability 1.2, whereas older GeForce 8 and 9 GPUs only supported Compute Capability 1.1. All GT21x GPUs also contain an audio processor inside and support 8 channel LPCM output through HDMI.
