The GeForce 9 series (also known as the GeForce 9000 series) is the ninth generation of Nvidia's GeForce line of graphics processing units, the first of which was released on February 21, 2008. The products are based on an updated Tesla microarchitecture, adding PCI Express 2.0 support, improved color and z-compression, and built on a 65 nm process, later using 55 nm process to reduce power consumption and die size (GeForce 8 G8x GPUs only supported PCIe 1.1 and were built on 90 nm process or 80 nm process).
650 MHz core clock, with a 1625 MHz unified shader clock
1008 MHz memory (2016 MHz datarate), 256-bit interface for 64.5 GB/s of bandwidth. (57.6 GB/s for 1800 MHz configuration)
512–2048 MB of GDDR3 or DDR2 memory
505M transistor count
DirectX 10.0, Shader Model 4.0, OpenGL 2.1, and PCI-Express 2.0[9]
Supports second-generation PureVideo HD technology with partial VC1 decoding
Is HDCP compatible, but its implementation depends on the manufacturer
Supports CUDA and the Quantum Effects physics processing engine
Almost double the performance of the previous Nvidia mid-range card, the GeForce 8600GTS
GeForce 9600 GS
The GeForce 9600GS is a Hewlett Packard OEM card. It is based on a G94a core clocked at 500 MHz. It features 768 MB of DDR2 memory on a 192-bit bus.
GeForce 9600 GSO
The GeForce 9600 GSO was essentially a renamed 8800 GS. This tactic has been seen before in products such as the GeForce 7900 GTO to clear unsold stock when it is made obsolete by the next generation. Just like the 8800 GS, the 9600 GSO features 96 stream processors, a 550 MHz core clock with shaders clocked at 1,375 MHz, and either 384 or 768 MB of memory clocked at 800 MHz on a 192-bit memory bus. Some manufacturers have mistakenly listed some of their 768 MB models that have 96 stream processors as being based on the G94 chip, rather than the G92.[10]
GeForce 9600 GSO 512
After clearing the old 8800 GS stock, Nvidia revised the specification with a new core, and 512 MB of memory clocked at 900 MHz on a 256-bit bus.[11] For these cards, the number of stream processors is halved to 48, with the core frequency increased to 650 MHz and the shader frequency increased to 1625 MHz. Some of these cards have 1024 megabytes of memory while still being a 512 model. The revised version is considered inferior in performance to the old version.[according to whom?]
GeForce 9600 GTX
XFX released a 9600 GTX based on the G92 chip featuring 96 stream processors, a 580 MHz core clock, 1450 MHz shaders and 512 MB of GDDR3 running at 1400 MHz on a 256-bit bus. Other than clock speeds, it is functionally the desktop equivalent version of the 9800M GT.[12]
GeForce 9800 series
The GeForce 9800 series contains the GX2 (dual GPU), GTX, GTX+ and GT variants.[13]
GeForce 9800 GX2
On March 18, 2008, the GeForce 9800 GX2 was officially launched.
The GeForce 9800 GX2 has the following specifications:[14][15]
Dual PCBs, dual GPU design
about 197 W power consumption.[16]
Two 65nm process GPUs, with 256 total stream processors (128 per PCB).[17][unreliable source?]
Supports Quad SLI
Power of Two underclocked GeForce 8800 GTS 512 (G92) video cards in SLI Mode
1 GiB (512 MiB per PCB) GDDR3 memory
Supports DirectX 10, Shader Model 4, OpenGL 3.3, and PCI-Express 2.0
Supports 2nd generation PureVideo HD technology with partial VC1 decoding
Outputs include two DVI ports, an HDMI output, and S/PDIF in connector on board for routing audio through the HDMI cable.[18][unreliable source?]
DirectX 10, Shader Model 4.0, OpenGL 3.3, and PCI-Express 2.0
Supports 2nd generation PureVideo HD technology with partial VC1 decoding
Outputs include two DVI ports, an HDMI output (using Nvidia DVI to HDMI adapter (included)), and S/PDIF in connector on board for routing audio through the HDMI cable
In July 2008 Nvidia released a refresh of the 9800 GTX: the 9800 GTX+ (55 nm manufacturing process). It has faster core (738 MHz) and shader (1836 MHz) clocks. Since March 2009 this design is manufactured as GeForce GTS 250.
GeForce 9800 GT
The 9800GT is identical to an 8800GT, although some were manufactured using a 55 nm technology instead of the 65 nm technology that debuted on the 8800GT.[24] The newer (55 nm) version supports HybridPower while the 65 nm version does not.
ASUSTeK have released a 9800GT with Tri-SLI support.[25]
