GeForce GTX 470 vs GeForce GTX 560 Ti 448

Intro

The GeForce GTX 470 makes use of a 40 nm design. nVidia has set the core frequency at 607 MHz. The GDDR5 RAM runs at a frequency of 837 MHz on this model. It features 448 SPUs as well as 56 Texture Address Units and 40 ROPs.

Compare those specifications to the GeForce GTX 560 Ti 448, which has GPU core speed of 732 MHz, and 1280 MB of GDDR5 RAM running at 900 MHz through a 320-bit bus. It also features 448 SPUs, 56 Texture Address Units, and 40 ROPs.

Specifications

Memory Bandwidth: Bandwidth is the max amount of data (measured in megabytes per second) that can be moved past the external memory interface in a second. The number is calculated by multiplying the bus width by its memory speed. If the card has DDR type RAM, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the better the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card could possibly write to its local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate is also dependant on lots of 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.
