GeForce GTX 950		105728 MB/sec
	Difference: 6160 (6%)

Texel Rate

The GeForce GTX 950 should be a bit (about 19%) more effective at texture filtering than the GeForce GTX 260 Core 216. (explain)

GeForce GTX 950		49152 Mtexels/sec
GeForce GTX 260 Core 216		41472 Mtexels/sec
	Difference: 7680 (19%)

Pixel Rate

The GeForce GTX 950 should be quite a bit (more or less 103%) more effective at anti-aliasing than the GeForce GTX 260 Core 216, and should be capable of handling higher resolutions without losing too much performance. (explain)

GeForce GTX 950		32768 Mpixels/sec
GeForce GTX 260 Core 216		16128 Mpixels/sec
	Difference: 16640 (103%)

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 (measured in MB per second) that can be moved across the external memory interface within a second. The number is calculated by multiplying the interface width by its memory clock speed. If it uses DDR RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the card's memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be processed per second. This figure is worked out by multiplying the total texture units of the card by the core clock speed of the chip. The better this number, the better the 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 number of pixels that the graphics chip could possibly record to the local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate also depends on lots of other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
