GeForce GTX 460 vs Radeon HD 5750 1GB

Intro

The GeForce GTX 460 makes use of a 40 nm design. nVidia has clocked the core frequency at 675 MHz. The GDDR5 RAM is set to run at a frequency of 900 MHz on this specific model. It features 336 SPUs along with 56 Texture Address Units and 24 Rasterization Operator Units.

Compare all that to the Radeon HD 5750 1GB, which uses a 40 nm design. AMD has set the core speed at 700 MHz. The GDDR5 memory runs at a frequency of 1150 MHz on this specific model. It features 720(144x5) SPUs along with 36 Texture Address Units and 16 ROPs.

Memory Bandwidth: Bandwidth is the max amount of information (measured in megabytes per second) that can be transferred over the external memory interface in one second. It is calculated by multiplying the card's interface width by its memory speed. In the case of DDR RAM, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, 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 number is calculated by multiplying the total texture units by the core clock speed of the chip. The better this number, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.

Pixel Rate: Pixel rate is the maximum number of pixels the video card could possibly write to its local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate is also dependant on lots of other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
