The GeForce 9 series is the ninth generation of NVIDIA's GeForce series of graphics processing units, the first of which was released on February 21, 2008. Products are based on a slightly repolished Tesla microarchitecture, adding PCIe 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).
On May 1, 2008 the GeForce 9300 GS was officially launched.
On August 27, 2008 the GeForce 9400 GT was officially launched.
On July 29, 2008 the GeForce 9500 GT was officially launched.
The 9500 GS is an OEM card that is based on the 9500 GT but geared towards the mainstream audience.
On February 21, 2008, the GeForce 9600 GT was officially launched. It was an upgrade of 8600 GTS.
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 o
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.
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. 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.
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.
The GeForce 9800 series contains the GX2 (dual GPU), GTX, GTX+ and GT variants.
On March 18, 2008 the GeForce 9800 GX2 was officially launched.
The GeForce 9800 GX2 has the following specifications:.
On April 1, 2008 the GeForce 9800 GTX was officially launched. It was basically an 8800 GTS 512MB with two SLI connectors, higher clock speeds, and support for Nvidia Hybrid Power, a technology that allows the discrete GPU to shut off during non resource intensive applications, and instead use the integrated GPU. With these extra features though, a high price came too.
