GeForce GTX 260 Core 216 vs GeForce GTX 560

Intro

Compare those specs to the GeForce GTX 560, which uses a 40 nm design. nVidia has set the core speed at 810 MHz. The GDDR5 memory works at a frequency of 1001 MHz on this specific model. It features 336 SPUs along with 56 Texture Address Units and 32 ROPs.

GeForce GTX 260 Core 216		41472 Mtexels/sec
	Difference: 3888 (9%)

Pixel Rate

The GeForce GTX 560 will be much (about 61%) better at full screen anti-aliasing than the GeForce GTX 260 Core 216, and capable of handling higher resolutions without losing too much performance. (explain)

GeForce GTX 560		25920 Mpixels/sec
GeForce GTX 260 Core 216		16128 Mpixels/sec
	Difference: 9792 (61%)

Please note that the above 'benchmarks' are all just theoretical - the results were calculated based on the card's specifications, and real-world performance may (and probably will) vary at least a bit.

Specifications

Memory Bandwidth: Bandwidth is the largest amount of data (measured in MB per second) that can be transported past the external memory interface within a second. The number is calculated by multiplying the card's interface width by its memory clock speed. If the card has DDR type memory, the result should be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card can possibly record to the local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the amount of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate also depends 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 maximum fill rate.
