GeForce GT 440 3GB vs GeForce GTX 260

Intro

The GeForce GT 440 3GB has a clock speed of 594 MHz and a GDDR3 memory speed of 900 MHz. It also features a 192-bit bus, and uses a 40 nm design. It is comprised of 144 SPUs, 24 TAUs, and 24 Raster Operation Units.

Compare all that to the GeForce GTX 260, which uses a 65 nm design. nVidia has set the core frequency at 576 MHz. The GDDR3 memory is set to run at a speed of 999 MHz on this model. It features 192 SPUs as well as 64 Texture Address Units and 28 Rasterization Operator Units.

Memory Bandwidth: Memory bandwidth is the largest amount of data (in units of megabytes per second) that can be transported across the external memory interface within a second. It is worked out by multiplying the bus width by its memory clock speed. In the case of DDR type RAM, it must be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the card's 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 texture map elements (texels) that are applied in one second. This is calculated by multiplying the total number of texture units of the card by the core clock speed of the chip. The better the texel rate, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second.

Pixel Rate: Pixel rate is the maximum number of pixels the video card could possibly write to the local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the amount of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate also depends on lots of other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
