The GeForce 9800 series contains the GX2 (dual GPU), GTX, GTX+ and GT variants.
GeForce 9800 GX2 On March 18, 2008, the GeForce 9800 GX2 was officially launched. The
GeForce 9800 GX2 has the following specifications: • Dual
PCBs, dual GPU design • about 197 W power consumption. • Two
65nm process GPUs, with 256 total stream processors (128 per PCB). • 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. • An 8-pin and a 6-pin power connector • Clocks (Core/Shader/Memory): 600 MHz/1500 MHz/2000 MHz • 256-bit memory interface
GeForce 9800 GTX On April 1, 2008, the GeForce 9800 GTX was officially launched. Taken from an eVGA specification sheet: • 128 CUDA cores • Clocks (Core/Shader/Memory): 675 MHz/1688 MHz/1100 MHz • 256-bit memory interface • 512 MB of GDDR3 memory • 70.4 GB/s memory bandwidth • Texture Fill Rate of 43.2 (billion/s) • 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 • Release date: 2008-04-01 • Launch Price of $349 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. The newer (55 nm) version supports
HybridPower while the 65 nm version does not. ASUSTeK have released a 9800GT with Tri-SLI support. Taken from the Nvidia product detail page. • 112 processor cores • 512–1024 MB of GDDR3 memory • 256-bit memory interface width • 600 MHz graphics clock • 1500 MHz processor clock • 900 MHz memory clock • 33.6 Gtexel/s texture fill rate • 57.6 GB/s memory bandwidth • Supports DirectX 10, Shader Model 4.0, OpenGL 3.3, and PCI-Express 2.0 • Supports 2nd generation
