GeForce 9600 GT 1GB vs GeForce GTS 250 512MB

Intro

The GeForce 9600 GT 1GB has a GPU core speed of 650 MHz, and the 1024 MB of GDDR3 RAM runs at 900 MHz through a 256-bit bus. It also is comprised of 64 SPUs, 32 Texture Address Units, and 16 ROPs.

Compare that to the GeForce GTS 250 512MB, which uses a 65/55 nm design. nVidia has clocked the core speed at 738 MHz. The GDDR3 memory is set to run at a speed of 1100 MHz on this specific model. It features 128 SPUs as well as 64 TAUs and 16 Rasterization Operator Units.

Memory Bandwidth: Memory bandwidth is the max amount of information (counted in MB per second) that can be transported over the external memory interface in a second. It is worked out by multiplying the card's bus width by its memory clock speed. If it uses DDR memory, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the better the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

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

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