GeForce 9600 GT 1GB vs GeForce GT 430 1GB

Intro

The GeForce 9600 GT 1GB uses a 65/55 nm design. nVidia has set the core speed at 650 MHz. The GDDR3 memory works at a frequency of 900 MHz on this particular model. It features 64 SPUs along with 32 TAUs and 16 Rasterization Operator Units.

Compare all that to the GeForce GT 430 1GB, which uses a 40 nm design. nVidia has clocked the core frequency at 700 MHz. The GDDR3 memory runs at a speed of 900 MHz on this particular model. It features 96 SPUs as well as 16 Texture Address Units and 4 ROPs.

Memory Bandwidth: Memory bandwidth is the max amount of information (measured in MB per second) that can be moved over the external memory interface within a second. It's calculated by multiplying the interface width by the speed of its memory. If the card has DDR memory, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the most pixels the video card could possibly write to the local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate also depends on many other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
