GeForce GT 230 vs GeForce GT 440 1.5GB

Intro

The GeForce GT 230 features a GPU core speed of 550 MHz, and the 1536 MB of DDR3 RAM is set to run at 800 MHz through a 192-bit bus. It also features 32 SPUs, 16 Texture Address Units, and 8 Raster Operation Units.

Compare all that to the GeForce GT 440 1.5GB, which comes with core speeds of 594 MHz on the GPU, and 900 MHz on the 1536 MB of GDDR3 RAM. It features 144 SPUs along with 24 Texture Address Units and 24 Rasterization Operator Units.

Memory Bandwidth: Memory bandwidth is the largest amount of information (counted in megabytes per second) that can be transferred across the external memory interface in a second. It is calculated by multiplying the card's interface width by the speed of its memory. If it uses DDR type RAM, the result should be multiplied by 2 once again. If 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 amount of texture map elements (texels) that can be applied in one second. This is worked out by multiplying the total texture units of the card by the core speed of the chip. The better this number, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels 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 one second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate also depends on many other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
