GeForce 8800 GS vs GeForce GT 440 1.5GB

Intro

The GeForce 8800 GS makes use of a 65 nm design. nVidia has set the core speed at 550 MHz. The GDDR3 RAM is set to run at a frequency of 800 MHz on this particular card. It features 96 SPUs as well as 48 TAUs and 12 Rasterization Operator Units.

Compare those specs to the GeForce GT 440 1.5GB, which has a clock speed of 594 MHz and a GDDR3 memory frequency of 900 MHz. It also makes use of a 192-bit bus, and makes use of a 40 nm design. It is made up of 144 SPUs, 24 TAUs, and 24 Raster Operation Units.

Memory Bandwidth: Memory bandwidth is the largest amount of information (in units of MB per second) that can be transferred past the external memory interface in one second. It is worked out by multiplying the card's interface width by its memory speed. If it uses DDR type RAM, the result should be multiplied by 2 once again. If DDR5, multiply by 4 instead. 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 amount of texture map elements (texels) that can be processed in one second. This number is worked out 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 amount of pixels the video card could possibly record to its local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the number of colour ROPs by the the core speed of the card. 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 quite a few other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
