GeForce 9600 GT 512MB vs GeForce GTX 550 Ti

Intro

The GeForce 9600 GT 512MB comes with a clock speed of 650 MHz and a GDDR3 memory frequency of 900 MHz. It also features a 256-bit memory bus, and uses a 65/55 nm design. It is made up of 64 SPUs, 32 TAUs, and 16 ROPs.

Compare those specifications to the GeForce GTX 550 Ti, which uses a 40 nm design. nVidia has clocked the core frequency at 900 MHz. The GDDR5 memory works at a frequency of 1026 MHz on this specific model. It features 192 SPUs as well as 32 Texture Address Units and 24 ROPs.

Memory Bandwidth: Memory bandwidth is the max amount of data (in units of megabytes per second) that can be transferred past the external memory interface in a second. It is worked out by multiplying the interface width by the speed of its memory. If it uses DDR RAM, the result should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher 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 can be applied per second. This is calculated by multiplying the total number of texture units of the card by the core speed of the chip. The higher this number, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip could possibly record to its local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of Raster Operations Pipelines by the clock 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 reach the max fill rate.
