GeForce 9800 GTX vs GeForce GTX 965M

Intro

The GeForce 9800 GTX has a GPU core clock speed of 675 MHz, and the 512 MB of GDDR3 RAM runs at 1100 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 965M, which comes with a core clock frequency of 944 MHz and a GDDR5 memory frequency of 1000 MHz. It also uses a 128-bit bus, and makes use of a 28 nm design. It is made up of 1024 SPUs, 64 TAUs, and 32 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GTX 965M 60 Watts
GeForce 9800 GTX 140 Watts
Difference: 80 Watts (133%)

Memory Bandwidth

Theoretically, the GeForce 9800 GTX should be a bit faster than the GeForce GTX 965M overall. (explain)

GeForce 9800 GTX 70400 MB/sec
GeForce GTX 965M 64000 MB/sec
Difference: 6400 (10%)

Texel Rate

The GeForce GTX 965M should be a lot (more or less 40%) more effective at anisotropic filtering than the GeForce 9800 GTX. (explain)

GeForce GTX 965M 60416 Mtexels/sec
GeForce 9800 GTX 43200 Mtexels/sec
Difference: 17216 (40%)

Pixel Rate

If using high levels of AA is important to you, then the GeForce GTX 965M is the winner, by far. (explain)

GeForce GTX 965M 30208 Mpixels/sec
GeForce 9800 GTX 10800 Mpixels/sec
Difference: 19408 (180%)

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 largest amount of data (counted in megabytes per second) that can be transported past the external memory interface in a second. The number is worked out by multiplying the card's bus width by its memory speed. In the case of DDR RAM, the result should be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the card's memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card can possibly write to the local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate also depends on lots of other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
