GeForce GTX 460 SE vs GeForce GTX 870M

Intro

The GeForce GTX 460 SE uses a 40 nm design. nVidia has set the core speed at 650 MHz. The GDDR5 RAM is set to run at a frequency of 850 MHz on this model. It features 288 SPUs as well as 48 TAUs and 32 ROPs.

Compare those specs to the GeForce GTX 870M, which comes with a core clock frequency of 941 MHz and a GDDR5 memory frequency of 1000 MHz. It also features a 192-bit memory bus, and makes use of a 28 nm design. It is comprised of 1344 SPUs, 112 Texture Address Units, and 24 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GTX 870M 110 Watts
GeForce GTX 460 SE 150 Watts
Difference: 40 Watts (36%)

Memory Bandwidth

As far as performance goes, the GeForce GTX 460 SE should in theory be just a bit superior to the GeForce GTX 870M overall. (explain)

GeForce GTX 460 SE 108800 MB/sec
GeForce GTX 870M 96000 MB/sec
Difference: 12800 (13%)

Texel Rate

The GeForce GTX 870M is quite a bit (more or less 238%) faster with regards to texture filtering than the GeForce GTX 460 SE. (explain)

GeForce GTX 870M 105392 Mtexels/sec
GeForce GTX 460 SE 31200 Mtexels/sec
Difference: 74192 (238%)

Pixel Rate

If using high levels of AA is important to you, then the GeForce GTX 870M is the winner, not by a very large margin though. (explain)

GeForce GTX 870M 22584 Mpixels/sec
GeForce GTX 460 SE 20800 Mpixels/sec
Difference: 1784 (9%)

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: Memory bandwidth is the maximum amount of information (in units of megabytes per second) that can be transported over the external memory interface within a second. The number is worked out by multiplying the interface width by its memory clock speed. In the case of DDR type RAM, the result should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the better the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are processed in one second. This is worked out by multiplying the total texture units of the card by the core clock speed of the chip. The higher this number, the better the graphics card will be at 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 that the graphics chip can possibly write to its local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output 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.
