GeForce 9800 GX2 vs GeForce GTX 880M

Intro

The GeForce 9800 GX2 comes with clock speeds of 600 MHz on the GPU, and 1000 MHz on the 512 MB of GDDR3 RAM. It features 128 SPUs as well as 64 Texture Address Units and 16 Rasterization Operator Units.

Compare all that to the GeForce GTX 880M, which makes use of a 28 nm design. nVidia has clocked the core frequency at 954 MHz. The GDDR5 memory works at a frequency of 1000 MHz on this specific model. It features 1536 SPUs along with 128 TAUs and 32 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GTX 880M 130 Watts
GeForce 9800 GX2 197 Watts
Difference: 67 Watts (52%)

Memory Bandwidth

Both cards have exactly the same bandwidth, so in theory they should have the same performance. (explain)

Texel Rate

The GeForce GTX 880M is much (approximately 59%) better at AF than the GeForce 9800 GX2. (explain)

GeForce GTX 880M 122112 Mtexels/sec
GeForce 9800 GX2 76800 Mtexels/sec
Difference: 45312 (59%)

Pixel Rate

The GeForce GTX 880M is much (more or less 59%) better at anti-aliasing than the GeForce 9800 GX2, and also will be able to handle higher screen resolutions more effectively. (explain)

GeForce GTX 880M 30528 Mpixels/sec
GeForce 9800 GX2 19200 Mpixels/sec
Difference: 11328 (59%)

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.

One or more cards in this comparison are multi-core. This means that their bandwidth, texel and pixel rates are theoretically doubled - this does not mean the card will actually perform twice as fast, but only that it should in theory be able to. Actual game benchmarks will give a more accurate idea of what it's capable of.

Memory Bandwidth: Bandwidth is the maximum amount of information (in units of megabytes per second) that can be transferred over the external memory interface within a second. It is worked out by multiplying the card's interface width by the speed of its memory. If the card has DDR RAM, the result should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be applied per second. This figure is worked out by multiplying the total number of texture units by the core 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 applied in one second.

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