GeForce GTX 460 SE vs GeForce GTX 870M

Intro

The GeForce GTX 460 SE uses a 40 nm design. nVidia has set the core frequency at 650 MHz. The GDDR5 RAM runs at a speed of 850 MHz on this model. It features 288 SPUs along with 48 Texture Address Units and 32 Rasterization Operator Units.

Compare those specifications to the GeForce GTX 870M, which features a core clock frequency of 941 MHz and a GDDR5 memory frequency of 1000 MHz. It also makes use of a 192-bit memory bus, and uses a 28 nm design. It is made up of 1344 SPUs, 112 TAUs, 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

Performance-wise, the GeForce GTX 460 SE should in theory be a little 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 anisotropic 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 running with high levels of AA is important to you, then the GeForce GTX 870M is the winner, but not by far. (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: Bandwidth is the max amount of data (measured in MB per second) that can be transferred over the external memory interface in a second. It's calculated by multiplying the bus width by its memory clock speed. If the card has DDR memory, it must be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the bandwidth is, the faster 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 amount of texture map elements (texels) that can be processed in one second. This figure is worked out by multiplying the total number of texture units by the core speed of the chip. The higher this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second.

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card can possibly record to its local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the amount of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also called 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 of the card - the lower the bandwidth is, the lower the potential to get to the max fill rate.
