GeForce 8800 GTS (G92) vs Radeon HD 5750 512MB

Intro

The GeForce 8800 GTS (G92) features a core clock speed of 650 MHz and a GDDR3 memory speed of 970 MHz. It also uses a 256-bit bus, and makes use of a 65 nm design. It is made up of 128 SPUs, 64 TAUs, and 16 Raster Operation Units.

Compare those specs to the Radeon HD 5750 512MB, which uses a 40 nm design. AMD has set the core speed at 700 MHz. The GDDR5 memory works at a speed of 1150 MHz on this model. It features 720(144x5) SPUs as well as 36 TAUs and 16 ROPs.

Memory Bandwidth: Bandwidth is the maximum amount of information (counted in megabytes per second) that can be transferred over the external memory interface in one second. It is worked out by multiplying the interface width by its memory speed. In the case of DDR RAM, it must be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the bandwidth is, the faster 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 are processed per second. This is calculated by multiplying the total texture units by the core speed of the chip. The higher the texel rate, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.

Pixel Rate: Pixel rate is the most pixels that the graphics card can possibly record to its local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the number of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate is also dependant on many other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
