GeForce GTX 460 vs Radeon HD 5770

Intro

The GeForce GTX 460 features a GPU core clock speed of 675 MHz, and the 768 MB of GDDR5 RAM is set to run at 900 MHz through a 192-bit bus. It also is made up of 336 Stream Processors, 56 Texture Address Units, and 24 Raster Operation Units.

Compare those specifications to the Radeon HD 5770, which makes use of a 40 nm design. AMD has clocked the core frequency at 850 MHz. The GDDR5 RAM runs at a speed of 1200 MHz on this card. It features 800(160x5) SPUs along with 40 TAUs and 16 ROPs.

Memory Bandwidth: Bandwidth is the max amount of information (counted in MB per second) that can be moved past the external memory interface in a second. It is worked out by multiplying the card's interface width by its memory speed. If it uses DDR type RAM, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the card's 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 number of texture map elements (texels) that can be processed in one second. This figure is worked out by multiplying the total texture units by the core clock speed of the chip. The higher the texel rate, the better the video 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 amount of pixels that the graphics card could possibly write to the local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the number of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate also depends on lots of other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
