GeForce GTX 280 vs GeForce GTX 880M

Intro

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

Compare all of that to the GeForce GTX 880M, which comes with a clock frequency of 954 MHz and a GDDR5 memory frequency of 1000 MHz. It also makes use of a 256-bit bus, and uses a 28 nm design. It is comprised of 1536 SPUs, 128 Texture Address Units, and 32 ROPs.

GeForce GTX 280 141696 MB/sec
GeForce GTX 880M 128000 MB/sec
Difference: 13696 (11%)

Texel Rate

The GeForce GTX 880M will be much (approximately 154%) more effective at anisotropic filtering than the GeForce GTX 280. (explain)

GeForce GTX 880M 122112 Mtexels/sec
GeForce GTX 280 48160 Mtexels/sec
Difference: 73952 (154%)

Pixel Rate

The GeForce GTX 880M should be quite a bit (more or less 58%) more effective at AA than the GeForce GTX 280, and will be capable of handling higher screen resolutions while still performing well. (explain)

GeForce GTX 880M 30528 Mpixels/sec
GeForce GTX 280 19264 Mpixels/sec
Difference: 11264 (58%)

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: Memory bandwidth is the max amount of information (counted in megabytes per second) that can be transferred across the external memory interface in a second. The number is worked out by multiplying the card's bus width by the speed of its memory. In the case of DDR RAM, it should be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are applied per second. This is worked out by multiplying the total number of texture units of the card by the core clock speed of the chip. The better 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 that the graphics chip can 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 Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate is also dependant on quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
