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. 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. GeForce 9800 Series 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 197 W power consumption. Two 65nm process GPUs, with 256 total stream processors (128 per PCB).
