GeForce 9800 GTX vs GeForce GTX 860M

Intro

The GeForce 9800 GTX uses a 65 nm design. nVidia has set the core speed at 675 MHz. The GDDR3 RAM works at a frequency of 1100 MHz on this particular model. It features 128 SPUs along with 64 TAUs and 16 ROPs.

Compare all that to the GeForce GTX 860M, which has a GPU core clock speed of 797 MHz, and 4096 MB of GDDR5 memory running at 1000 MHz through a 128-bit bus. It also is made up of 1152 SPUs, 96 TAUs, and 16 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GTX 860M 45 Watts
GeForce 9800 GTX 140 Watts
Difference: 95 Watts (211%)

Memory Bandwidth

In theory, the GeForce 9800 GTX should be just a bit faster than the GeForce GTX 860M in general. (explain)

GeForce 9800 GTX 70400 MB/sec
GeForce GTX 860M 64000 MB/sec
Difference: 6400 (10%)

Texel Rate

The GeForce GTX 860M will be a lot (more or less 77%) more effective at AF than the GeForce 9800 GTX. (explain)

GeForce GTX 860M 76512 Mtexels/sec
GeForce 9800 GTX 43200 Mtexels/sec
Difference: 33312 (77%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the GeForce GTX 860M is the winner, but not by far. (explain)

GeForce GTX 860M 12752 Mpixels/sec
GeForce 9800 GTX 10800 Mpixels/sec
Difference: 1952 (18%)

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: Bandwidth is the maximum amount of information (counted in megabytes per second) that can be transferred past the external memory interface in one second. The number is worked out by multiplying the card's interface width by its memory speed. In the case of DDR RAM, it must be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the faster the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card can possibly write to the local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the number of Render Output Units by the clock 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 rate also depends on many other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the max fill rate.
