GeForce 8800 GT 512MB vs GeForce 9500 GT 1GB GDDR3

Intro

The GeForce 8800 GT 512MB features a GPU core clock speed of 600 MHz, and the 512 MB of GDDR3 RAM runs at 900 MHz through a 256-bit bus. It also is comprised of 112 SPUs, 56 TAUs, and 16 Raster Operation Units.

Compare all of that to the GeForce 9500 GT 1GB GDDR3, which features core clock speeds of 550 MHz on the GPU, and 800 MHz on the 1024 MB of GDDR3 memory. It features 32 SPUs as well as 16 Texture Address Units and 8 Rasterization Operator Units.

Memory Bandwidth: Bandwidth is the maximum amount of data (in units of megabytes per second) that can be moved past the external memory interface in a second. It's calculated by multiplying the card's interface width by the speed of its memory. If it uses DDR RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied in one second. This number is worked out by multiplying the total amount of texture units by the core speed of the chip. The better the texel rate, the better the video 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 maximum amount of pixels the video card could possibly write to its local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the number of Render Output Units by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate also depends on many other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the max fill rate.
