GeForce GTX 260 vs GeForce GTX 560

Intro

The GeForce GTX 260 comes with a GPU clock speed of 576 MHz, and the 896 MB of GDDR3 RAM runs at 999 MHz through a 448-bit bus. It also is comprised of 192 SPUs, 64 TAUs, and 28 ROPs.

Compare that to the GeForce GTX 560, which has a core clock speed of 810 MHz and a GDDR5 memory frequency of 1001 MHz. It also features a 256-bit bus, and makes use of a 40 nm design. It is made up of 336 SPUs, 56 Texture Address Units, and 32 ROPs.

GeForce GTX 260 111888 MB/sec
Difference: 16240 (15%)

Texel Rate

The GeForce GTX 560 will be quite a bit (about 23%) faster with regards to anisotropic filtering than the GeForce GTX 260. (explain)

GeForce GTX 560 45360 Mtexels/sec
GeForce GTX 260 36864 Mtexels/sec
Difference: 8496 (23%)

Pixel Rate

The GeForce GTX 560 will be a lot (more or less 61%) more effective at full screen anti-aliasing than the GeForce GTX 260, and also should be capable of handling higher resolutions without slowing down too much. (explain)

GeForce GTX 560 25920 Mpixels/sec
GeForce GTX 260 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.

Memory Bandwidth: Bandwidth is the max amount of information (in units of megabytes per second) that can be transferred over the external memory interface in one second. The number is calculated by multiplying the bus width by its memory clock speed. In the case of DDR memory, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the 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 amount of texture map elements (texels) that are processed per second. This figure is calculated by multiplying the total amount of texture units by the core clock speed of the chip. The higher this number, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second.

Pixel Rate: Pixel rate is the most pixels the graphics card can possibly write to its local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of Raster Operations Pipelines by the the core 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 fill rate is also dependant on many other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
