GeForce 9500 GT 1GB GDDR3 vs Radeon HD 6750

Intro

The GeForce 9500 GT 1GB GDDR3 makes use of a 55 nm design. nVidia has clocked the core frequency at 550 MHz. The GDDR3 memory works at a frequency of 800 MHz on this specific card. It features 32 SPUs along with 16 Texture Address Units and 8 Rasterization Operator Units.

Compare those specifications to the Radeon HD 6750, which features clock speeds of 725 MHz on the GPU, and 1000 MHz on the 512 MB of GDDR5 RAM. It features 720 SPUs as well as 36 TAUs and 16 ROPs.

Memory Bandwidth: Bandwidth is the max amount of data (counted in MB per second) that can be transferred past the external memory interface within a second. It's calculated by multiplying the bus width by its memory speed. If the card has DDR type RAM, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the most pixels the graphics card can possibly write to the local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the number of ROPs 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 output rate also depends on quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
