GeForce GTX 460 1GB vs GeForce GTX 560

Intro

The GeForce GTX 460 1GB has a clock frequency of 675 MHz and a GDDR5 memory frequency of 900 MHz. It also makes use of a 256-bit memory bus, and makes use of a 40 nm design. It is made up of 336 SPUs, 56 Texture Address Units, and 32 Raster Operation Units.

Compare those specifications to the GeForce GTX 560, which comes with GPU core speed of 810 MHz, and 1024 MB of GDDR5 memory running at 1001 MHz through a 256-bit bus. It also features 336 SPUs, 56 TAUs, and 32 ROPs.

Memory Bandwidth: Bandwidth is the max amount of data (in units of megabytes per second) that can be transferred over the external memory interface in one second. The number is worked out by multiplying the interface width by the speed of its memory. If it uses DDR RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the faster 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 can be processed per second. This number is worked out by multiplying the total number of texture units of the card by the core speed of the chip. The better the texel rate, the better the video 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 that the graphics card could possibly record to the local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the number of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate is also dependant on lots of other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the max fill rate.
