GeForce 9800 GX2 vs GeForce GTX 860M

Intro

The GeForce 9800 GX2 features a GPU clock speed of 600 MHz, and the 512 MB of GDDR3 RAM runs at 1000 MHz through a 256-bit bus. It also is comprised of 128 Stream Processors, 64 TAUs, and 16 Raster Operation Units.

Compare those specs to the GeForce GTX 860M, which has a clock speed of 797 MHz and a GDDR5 memory speed of 1000 MHz. It also features a 128-bit bus, and makes use of a 28 nm design. It is made up of 1152 SPUs, 96 Texture Address Units, and 16 Raster Operation Units.

GeForce GTX 860M 64000 MB/sec
Difference: 64000 (100%)

Texel Rate

The GeForce 9800 GX2 should be a small bit (approximately 0%) more effective at texture filtering than the GeForce GTX 860M. (explain)

GeForce 9800 GX2 76800 Mtexels/sec
GeForce GTX 860M 76512 Mtexels/sec
Difference: 288 (0%)

Pixel Rate

If running with a high resolution is important to you, then the GeForce 9800 GX2 is the winner, by far. (explain)

GeForce 9800 GX2 19200 Mpixels/sec
GeForce GTX 860M 12752 Mpixels/sec
Difference: 6448 (51%)

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 largest amount of data (counted in megabytes per second) that can be transported over the external memory interface in one second. The number is calculated by multiplying the interface width by the speed of its memory. In the case of DDR RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be applied in one second. This number is calculated by multiplying the total amount of texture units of the card by the core clock speed of the chip. The better the texel rate, the better the 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 most pixels the video card could possibly write to its local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the amount of colour ROPs 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 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 max fill rate.
