GeForce GTX 560 vs GeForce GTX 560 Ti

Intro

The GeForce GTX 560 makes use of a 40 nm design. nVidia has clocked the core frequency at 810 MHz. The GDDR5 memory works at a frequency of 1001 MHz on this particular card. It features 336 SPUs along with 56 Texture Address Units and 32 ROPs.

Compare that to the GeForce GTX 560 Ti, which uses a 40 nm design. nVidia has set the core speed at 822 MHz. The GDDR5 RAM runs at a frequency of 1002 MHz on this card. It features 384 SPUs along with 64 TAUs and 32 Rasterization Operator Units.

Specifications

Memory Bandwidth: Bandwidth is the maximum amount of data (measured in megabytes per second) that can be transferred past the external memory interface in a second. It is calculated by multiplying the bus width by its memory clock speed. If it uses DDR type RAM, it must be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, 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 processed per second. This number is worked out by multiplying the total amount of texture units by the core speed of the chip. The better the texel rate, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second.

Pixel Rate: Pixel rate is the most pixels the graphics card can possibly write to the local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate also depends on many other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
