GeForce GTX 280 vs GeForce GTX 560

Intro

The GeForce GTX 280 features a clock frequency of 602 MHz and a GDDR3 memory frequency of 1107 MHz. It also makes use of a 512-bit bus, and uses a 65 nm design. It is made up of 240 SPUs, 80 Texture Address Units, and 32 Raster Operation Units.

Compare that to the GeForce GTX 560, which comes with clock speeds of 810 MHz on the GPU, and 1001 MHz on the 1024 MB of GDDR5 RAM. It features 336 SPUs along with 56 TAUs and 32 ROPs.

Difference: 86 Watts (57%)

Memory Bandwidth

The GeForce GTX 280, in theory, should be a little bit faster than the GeForce GTX 560 in general. (explain)

GeForce GTX 280 141696 MB/sec
GeForce GTX 560 128128 MB/sec
Difference: 13568 (11%)

Texel Rate

The GeForce GTX 280 will be a bit (more or less 6%) better at texture filtering than the GeForce GTX 560. (explain)

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

Pixel Rate

If using lots of anti-aliasing is important to you, then the GeForce GTX 560 is a better choice, and very much so. (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 maximum amount of information (counted in megabytes per second) that can be transferred over the external memory interface in a second. The number is worked out by multiplying the bus width by its memory clock speed. In the case of DDR type memory, the result should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the memory bandwidth, the better 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 texture map elements (texels) that are applied per second. This is worked out by multiplying the total amount of texture units 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 per second.

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card could possibly record to the local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate also depends on many other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the max fill rate.
