GeForce GTX 280 vs GeForce GTX 560

Intro

The GeForce GTX 280 has clock speeds of 602 MHz on the GPU, and 1107 MHz on the 1024 MB of GDDR3 memory. It features 240 SPUs along with 80 TAUs and 32 Rasterization Operator Units.

Compare those specifications to the GeForce GTX 560, which comes with a clock speed of 810 MHz and a GDDR5 memory frequency of 1001 MHz. It also makes use of a 256-bit memory bus, and makes use of a 40 nm design. It is made up of 336 SPUs, 56 Texture Address Units, and 32 Raster Operation Units.

GeForce GTX 280 48160 Mtexels/sec
GeForce GTX 560 45360 Mtexels/sec
Difference: 2800 (6%)

Pixel Rate

The GeForce GTX 560 is much (more or less 35%) faster with regards to AA than the GeForce GTX 280, and also capable of handling higher resolutions without losing too much performance. (explain)

GeForce GTX 560 25920 Mpixels/sec
GeForce GTX 280 19264 Mpixels/sec
Difference: 6656 (35%)

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 largest amount of data (in units of MB per second) that can be moved over the external memory interface in one second. The number is calculated by multiplying the card's interface width by its memory clock speed. If it uses DDR type memory, it must 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 AA, High Dynamic Range and high resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels the video card can possibly write to its local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the number of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. 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 reach the max fill rate.
