GeForce GTX 460 SE vs GeForce GTX 965M

Intro

Compare those specifications to the GeForce GTX 965M, which features a GPU core clock speed of 944 MHz, and 2048 MB of GDDR5 memory set to run at 1000 MHz through a 128-bit bus. It also is made up of 1024 SPUs, 64 Texture Address Units, and 32 Raster Operation Units.

GeForce GTX 965M		64000 MB/sec
	Difference: 44800 (70%)

Texel Rate

The GeForce GTX 965M is quite a bit (approximately 94%) faster with regards to texture filtering than the GeForce GTX 460 SE. (explain)

GeForce GTX 965M		60416 Mtexels/sec
GeForce GTX 460 SE		31200 Mtexels/sec
	Difference: 29216 (94%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the GeForce GTX 965M is a better choice, and very much so. (explain)

GeForce GTX 965M		30208 Mpixels/sec
GeForce GTX 460 SE		20800 Mpixels/sec
	Difference: 9408 (45%)

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: Memory bandwidth is the maximum amount of data (measured in megabytes per second) that can be moved past the external memory interface in a second. It is worked out by multiplying the card's bus width by its memory clock speed. If the card has DDR type memory, it should be multiplied by 2 once 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, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be processed in one second. This is worked out by multiplying the total amount of texture units of the card by the core speed of the chip. The better the texel rate, the better the video card will be at 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 card could possibly record to its local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the number of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate is also dependant on many other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
