GeForce GTX 285 2GB vs GeForce GTX 880M

Intro

The GeForce GTX 285 2GB features a clock frequency of 648 MHz and a GDDR3 memory speed of 1242 MHz. It also uses a 512-bit memory bus, and makes use of a 55 nm design. It is made up of 240 SPUs, 80 TAUs, and 32 ROPs.

Compare those specs to the GeForce GTX 880M, which makes use of a 28 nm design. nVidia has set the core speed at 954 MHz. The GDDR5 RAM runs at a frequency of 1000 MHz on this specific model. It features 1536 SPUs along with 128 Texture Address Units and 32 ROPs.

GeForce GTX 285 2GB 158976 MB/sec
GeForce GTX 880M 128000 MB/sec
Difference: 30976 (24%)

Texel Rate

The GeForce GTX 880M is much (more or less 136%) faster with regards to AF than the GeForce GTX 285 2GB. (explain)

GeForce GTX 880M 122112 Mtexels/sec
GeForce GTX 285 2GB 51840 Mtexels/sec
Difference: 70272 (136%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the GeForce GTX 880M is a better choice, by a large margin. (explain)

GeForce GTX 880M 30528 Mpixels/sec
GeForce GTX 285 2GB 20736 Mpixels/sec
Difference: 9792 (47%)

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 moved over the external memory interface in one second. The number is worked out by multiplying the bus width by its memory clock speed. In the case of DDR memory, the result should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the card's 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 number of texture map elements (texels) that can be applied per second. This figure is worked out by multiplying the total amount of texture units of the card by the core clock speed of the chip. The better this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card could possibly write to its local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate is also dependant on lots of other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the max fill rate.
