GeForce GTX 280 vs GeForce GTX 880M

Intro

The GeForce GTX 280 features a GPU core clock speed of 602 MHz, and the 1024 MB of GDDR3 RAM runs at 1107 MHz through a 512-bit bus. It also is comprised of 240 Stream Processors, 80 Texture Address Units, and 32 Raster Operation Units.

Compare that to the GeForce GTX 880M, which comes with GPU core speed of 954 MHz, and 4096 MB of GDDR5 RAM set to run at 1000 MHz through a 256-bit bus. It also features 1536 Stream Processors, 128 TAUs, and 32 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GTX 880M 130 Watts
GeForce GTX 280 236 Watts
Difference: 106 Watts (82%)

Memory Bandwidth

Theoretically speaking, the GeForce GTX 280 should be a small bit faster than the GeForce GTX 880M in general. (explain)

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

Texel Rate

The GeForce GTX 880M is quite a bit (more or less 154%) better at texture filtering than the GeForce GTX 280. (explain)

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

Pixel Rate

If running with a high screen resolution is important to you, then the GeForce GTX 880M is superior to the GeForce GTX 280, and very much so. (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 data (counted in MB per second) that can be transported past the external memory interface in a second. The number is calculated by multiplying the card's bus width by its memory clock speed. If it uses DDR type memory, it should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the faster 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 number of texture map elements (texels) that are processed per second. This is worked out by multiplying the total texture units by the core speed of the chip. The better the texel rate, the better the video 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 maximum amount of pixels the graphics card can possibly write to its local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate is also dependant on quite a few other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
