GeForce 9500 GT 1GB GDDR3 vs GeForce GT 440 1.5GB

Intro

The GeForce 9500 GT 1GB GDDR3 features a clock speed of 550 MHz and a GDDR3 memory speed of 800 MHz. It also features a 128-bit memory bus, and makes use of a 55 nm design. It is made up of 32 SPUs, 16 Texture Address Units, and 8 Raster Operation Units.

Compare all that to the GeForce GT 440 1.5GB, which features a core clock frequency of 594 MHz and a GDDR3 memory frequency of 900 MHz. It also uses a 192-bit bus, and makes use of a 40 nm design. It is comprised of 144 SPUs, 24 Texture Address Units, and 24 Raster Operation Units.

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

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

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card could possibly write to its local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate is also dependant on quite a few other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
