GeForce 9600 GT 1GB vs GeForce GT 430 1GB


Intro

The GeForce 9600 GT 1GB features a clock frequency of 650 MHz and a GDDR3 memory speed of 900 MHz. It also uses a 256-bit memory bus, and makes use of a 65/55 nm design. It is made up of 64 SPUs, 32 Texture Address Units, and 16 ROPs.

Compare those specs to the GeForce GT 430 1GB, which comes with a clock frequency of 700 MHz and a GDDR3 memory frequency of 900 MHz. It also uses a 128-bit bus, and makes use of a 40 nm design. It is comprised of 96 SPUs, 16 TAUs, and 4 Raster Operation Units.

Memory Bandwidth: Memory bandwidth is the maximum amount of information (in units of MB per second) that can be moved across the external memory interface within a second. The number is calculated by multiplying the card's interface width by its memory speed. If the card has DDR type memory, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the faster 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 can be processed in one second. This is worked out by multiplying the total number of texture units of the card by the core speed of the chip. The higher the texel rate, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card could possibly record to the local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate also depends on lots of other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the max fill rate.
