GeForce GTX 460 (OEM) vs GeForce GTX 960M

Intro

Compare all that to the GeForce GTX 960M, which makes use of a 28 nm design. nVidia has clocked the core frequency at 1096 MHz. The GDDR5 memory works at a speed of 1000 MHz on this specific model. It features 640 SPUs along with 40 TAUs and 16 Rasterization Operator Units.

GeForce GTX 460 (OEM)		36400 Mtexels/sec
	Difference: 7440 (20%)

Pixel Rate

If running with a high screen resolution is important to you, then the GeForce GTX 460 (OEM) is the winner, but not by far. (explain)

GeForce GTX 460 (OEM)		20800 Mpixels/sec
GeForce GTX 960M		17536 Mpixels/sec
	Difference: 3264 (19%)

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.

Specifications

Memory Bandwidth: Bandwidth is the largest amount of data (counted in megabytes per second) that can be transferred past the external memory interface within a second. The number is calculated by multiplying the interface width by the speed of its memory. In the case of DDR RAM, the result should 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 anti-aliasing, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the most pixels that the graphics chip could possibly record to the local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of Render Output Units 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 rate also depends on lots of other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the max fill rate.
