GeForce 9500 GT DDR2 vs GeForce 9600 GSO 512MB

Intro

The GeForce 9500 GT DDR2 has a GPU core speed of 550 MHz, and the 256 MB of DDR2 RAM runs at 500 MHz through a 128-bit bus. It also is comprised of 32 SPUs, 16 Texture Address Units, and 8 Raster Operation Units.

Compare those specs to the GeForce 9600 GSO 512MB, which has a core clock frequency of 650 MHz and a GDDR3 memory frequency of 900 MHz. It also makes use of a 256-bit memory bus, and makes use of a 65/55 nm design. It is made up of 96 SPUs, 48 TAUs, and 16 Raster Operation Units.

Memory Bandwidth: Bandwidth is the max amount of information (in units of megabytes per second) that can be moved past the external memory interface in one second. The number is calculated by multiplying the bus width by its memory speed. In the case of DDR RAM, it must be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the bandwidth is, the better the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be processed in one second. This is calculated by multiplying the total texture units by the core speed of the chip. The higher this number, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second.

Pixel Rate: Pixel rate is the most pixels the graphics card can possibly write to the local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the number of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate is also dependant on lots of other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
