GeForce GTX 470 vs GeForce GTX 560 Ti 448

Intro

The GeForce GTX 470 comes with a clock frequency of 607 MHz and a GDDR5 memory speed of 837 MHz. It also makes use of a 320-bit memory bus, and makes use of a 40 nm design. It is comprised of 448 SPUs, 56 Texture Address Units, and 40 Raster Operation Units.

Compare those specifications to the GeForce GTX 560 Ti 448, which comes with a clock frequency of 732 MHz and a GDDR5 memory frequency of 900 MHz. It also makes use of a 320-bit memory bus, and makes use of a 40 nm design. It is comprised of 448 SPUs, 56 Texture Address Units, and 40 Raster Operation Units.

Specifications

Memory Bandwidth: Memory bandwidth is the largest amount of information (measured in megabytes per second) that can be transported past the external memory interface in one second. The number is worked out by multiplying the card's interface width by its memory clock speed. In the case of DDR type memory, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are applied in one second. This is calculated by multiplying the total texture units of the card by the core speed of the chip. The better this number, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second.

Pixel Rate: Pixel rate is the most pixels the video card could possibly record to its local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of colour ROPs by the the core speed of the card. 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 quite a few other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
