GeForce 9500 GT DDR2 vs Radeon HD 5670

Intro

The GeForce 9500 GT DDR2 features a GPU core speed of 550 MHz, and the 256 MB of DDR2 memory is set to run at 500 MHz through a 128-bit bus. It also is comprised of 32 Stream Processors, 16 TAUs, and 8 Raster Operation Units.

Compare those specifications to the Radeon HD 5670, which uses a 40 nm design. AMD has set the core speed at 775 MHz. The GDDR5 memory works at a frequency of 1000 MHz on this particular card. It features 400(80x5) SPUs as well as 20 TAUs and 8 ROPs.

Memory Bandwidth: Bandwidth is the largest amount of information (measured in MB per second) that can be transported over the external memory interface in a second. It's calculated by multiplying the card's bus width by its memory clock speed. If the card has DDR type memory, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the bandwidth is, the better the card will be in general. It especially helps with AA, HDR and high 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 number of texture units of the card by the core clock speed of the chip. The better this number, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card can possibly write to its local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate also depends on many other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
