Compare any two graphics cards:

GeForce GTX 275 vs Radeon HD 7750


The GeForce GTX 275 features a GPU core speed of 633 MHz, and the 896 MB of GDDR3 RAM is set to run at 1134 MHz through a 448-bit bus. It also is made up of 240 SPUs, 80 Texture Address Units, and 28 Raster Operation Units.

Compare that to the Radeon HD 7750, which comes with a core clock frequency of 800 MHz and a GDDR5 memory frequency of 1125 MHz. It also uses a 128-bit bus, and makes use of a 28 nm design. It is comprised of 512 SPUs, 32 TAUs, and 16 Raster Operation Units.

Memory Bandwidth: Memory bandwidth is the largest amount of information (in units of megabytes per second) that can be transported across the external memory interface within a second. The number is worked out by multiplying the bus width by its memory speed. If the card has DDR RAM, it must be multiplied by 2 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, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be applied per second. This figure is worked out by multiplying the total texture units by the core speed of the chip. The higher this number, the better the card will be at 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 that the graphics chip could possibly record to the local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate is also dependant on many other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
