VS

GeForce 9600 GT 1GB vs GeForce GTX 550 Ti

Intro

The GeForce 9600 GT 1GB comes with core clock speeds of 650 MHz on the GPU, and 900 MHz on the 1024 MB of GDDR3 RAM. It features 64 SPUs along with 32 TAUs and 16 ROPs.

Compare that to the GeForce GTX 550 Ti, which comes with core speeds of 900 MHz on the GPU, and 1026 MHz on the 1024 MB of GDDR5 RAM. It features 192 SPUs as well as 32 Texture Address Units and 24 ROPs.

Memory Bandwidth: Memory bandwidth is the max amount of data (counted in megabytes per second) that can be transferred past the external memory interface in a second. The number is worked out by multiplying the interface width by its memory speed. If it uses DDR type memory, the result should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be 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 better the texel rate, the better the 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 amount of pixels the video card could possibly record to its local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the number of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate is also dependant on many other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
