Texel Rate

The GeForce GTX 950 will be much (approximately 30%) more effective at texture filtering than the GeForce GTX 460 2GB. (explain)

GeForce GTX 950		49152 Mtexels/sec
GeForce GTX 460 2GB		37800 Mtexels/sec
	Difference: 11352 (30%)

Pixel Rate

The GeForce GTX 950 is much (about 52%) faster with regards to full screen anti-aliasing than the GeForce GTX 460 2GB, and should be capable of handling higher resolutions more effectively. (explain)

GeForce GTX 950		32768 Mpixels/sec
GeForce GTX 460 2GB		21600 Mpixels/sec
	Difference: 11168 (52%)

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 transported across the external memory interface in a second. The number is worked out by multiplying the bus width by the speed of its memory. In the case of DDR type RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, 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 are applied per second. This is calculated by multiplying the total texture units by the core speed of the chip. The higher the texel rate, the better the 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 card can possibly record to the local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of colour ROPs by the the core speed of the card. 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 quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
