GeForce GT 320 vs GeForce GTX 560 Ti 448

Intro

The GeForce GT 320 makes use of a 40 nm design. nVidia has set the core frequency at 540 MHz. The GDDR3 memory runs at a frequency of 790 MHz on this particular card. It features 72 SPUs as well as 24 Texture Address Units and 8 Rasterization Operator Units.

Compare those specifications to the GeForce GTX 560 Ti 448, which features core speeds of 732 MHz on the GPU, and 900 MHz on the 1280 MB of GDDR5 RAM. It features 448 SPUs as well as 56 Texture Address Units and 40 ROPs.

Memory Bandwidth: Bandwidth is the max amount of information (measured in megabytes per second) that can be transported past the external memory interface in a second. It's calculated by multiplying the bus width by the speed of its memory. If the card has DDR RAM, it should 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 higher screen resolutions.

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

Pixel Rate: Pixel rate is the most pixels that the graphics chip could possibly record to its local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number 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, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
