GeForce GTX 460 SE vs GeForce GTX 870M

Intro

The GeForce GTX 460 SE has a GPU core clock speed of 650 MHz, and the 1024 MB of GDDR5 RAM is set to run at 850 MHz through a 256-bit bus. It also is comprised of 288 SPUs, 48 TAUs, and 32 ROPs.

Compare all of that to the GeForce GTX 870M, which features clock speeds of 941 MHz on the GPU, and 1000 MHz on the 3072 MB of GDDR5 RAM. It features 1344 SPUs as well as 112 TAUs and 24 ROPs.

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

Memory Bandwidth

Theoretically speaking, the GeForce GTX 460 SE should be 13% quicker than the GeForce GTX 870M overall, due to its higher bandwidth. (explain)

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

Texel Rate

The GeForce GTX 870M should be much (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

The GeForce GTX 870M should be a small bit (about 9%) faster with regards to anti-aliasing than the GeForce GTX 460 SE, and also capable of handling higher screen resolutions while still performing well. (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 max amount of data (counted in MB per second) that can be transferred over the external memory interface in a second. It's calculated by multiplying the card's interface width by its memory speed. In the case of DDR RAM, it must be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, 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 texture map elements (texels) that are processed in one second. This number is worked out by multiplying the total texture units by the core speed of the chip. The better this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip can possibly record to its local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the number of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate also depends on lots of other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
