GeForce GT 320 vs Geforce GTX 760

Intro

The GeForce GT 320 makes use of a 40 nm design. nVidia has set the core speed at 540 MHz. The GDDR3 memory is set to run at a speed of 790 MHz on this specific card. It features 72 SPUs along with 24 Texture Address Units and 8 Rasterization Operator Units.

Compare those specs to the Geforce GTX 760, which makes use of a 28 nm design. nVidia has clocked the core speed at 980 MHz. The GDDR5 RAM works at a speed of 1502 MHz on this card. It features 1152 SPUs along with 96 Texture Address Units and 32 Rasterization Operator Units.

Memory Bandwidth: Bandwidth is the largest amount of data (counted in megabytes per second) that can be moved across the external memory interface in one second. It is calculated by multiplying the card's bus width by the speed of its memory. If it uses DDR type memory, it must be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics 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 amount of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel 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.
