GeForce 200 series
series of graphic cards developed by Nvidia
The GeForce 200 series is a series of Tesla-based GeForce graphics processing units developed by Nvidia. Introduced in 2008, it succeeded the GeForce 9 series. The series introduced Nvidia's second generation of the Tesla microarchitecture, the first major update to it since the GeForce 8 series.
Architecture
The GeForce 200 series introduced Nvidia's second generation of the Tesla microarchitecture, Nvidia's unified shader architecture; the first major update to it since introduced with the GeForce 8 series.
The GeForce GTX 280 and GTX 260 are based on the same processor core. During the manufacturing process, GTX chips were binned and separated through defect testing of the core's logic functionality. Those that failed to meet the GTX 280 hardware specification were re-tested and binned as GTX 260 (which is specified with fewer stream processors, fewer ROPs and a narrower memory bus).
In late 2008, Nvidia re-released the GTX 260 with 216 stream processors, up from 192. Effectively, there were 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.
This brief starts where responsible research should: with the source description of “GeForce 200 series” as series of graphic cards developed by Nvidia. Everything that follows is an evidence route, not borrowed authority.
Why this record matters
The subject matters to the general reference register because the source frames it as series of graphic cards developed by Nvidia. Its deeper value depends on whether names, dates, institutions and citations support that framing.
Named sources, stable identifiers and responsible institutions provide the strongest route from overview to verifiable evidence. The source revision retrieved here is dated Sep 5, 2026. The linked authority identifier is Q137255. None of the 0 selected statements returned an explicit reference. The first chronological checks are 2008.
The absence of detail may reflect summary conventions rather than a lack of surviving documentation. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
