GeForce GTX 460 1GB vs GeForce GTX 950M

Intro

Compare those specs to the GeForce GTX 950M, which comes with clock speeds of 914 MHz on the GPU, and 1000 MHz on the 2048 MB of DDR3 RAM. It features 640 SPUs along with 40 TAUs and 16 ROPs.

GeForce GTX 950M		32000 MB/sec
	Difference: 83200 (260%)

Texel Rate

The GeForce GTX 460 1GB should be a little bit (approximately 3%) more effective at AF than the GeForce GTX 950M. (explain)

GeForce GTX 460 1GB		37800 Mtexels/sec
GeForce GTX 950M		36560 Mtexels/sec
	Difference: 1240 (3%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the GeForce GTX 460 1GB is superior to the GeForce GTX 950M, by a large margin. (explain)

GeForce GTX 460 1GB		21600 Mpixels/sec
GeForce GTX 950M		14624 Mpixels/sec
	Difference: 6976 (48%)

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 maximum amount of data (counted in MB per second) that can be moved over the external memory interface in a second. It is calculated by multiplying the bus width by the speed of its memory. If it uses DDR memory, it should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the card's memory bandwidth, the faster 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 texture map elements (texels) that are applied per second. This number is worked out by multiplying the total texture units of the card by the core speed of the chip. The higher this number, the better the 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 write to the local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the number of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate is also dependant on quite a few other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
