GeForce 9800 GX2 vs GeForce GTX 860M

Intro

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

Compare all of that to the GeForce GTX 860M, which has core speeds of 797 MHz on the GPU, and 1000 MHz on the 4096 MB of GDDR5 memory. It features 1152 SPUs as well as 96 TAUs and 16 ROPs.

Theoretically speaking, the GeForce 9800 GX2 is 100% quicker than the GeForce GTX 860M overall, because of its greater data rate. (explain)

GeForce 9800 GX2 128000 MB/sec
GeForce GTX 860M 64000 MB/sec
Difference: 64000 (100%)

Texel Rate

The GeForce 9800 GX2 will be a small bit (more or less 0%) faster with regards to anisotropic 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 a better choice, 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: Memory bandwidth is the maximum amount of data (measured in megabytes per second) that can be transferred over the external memory interface in a second. It's worked out by multiplying the interface width by its memory clock speed. If the card has DDR RAM, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are processed in one second. This figure is calculated by multiplying the total texture units by the core speed of the chip. The higher the texel rate, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second.

Pixel Rate: Pixel rate is the most pixels the video card can possibly write to the local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the amount of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate also depends on many other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
