GeForce GTX 950		105728 MB/sec
	Difference: 353024 (334%)

Texel Rate

The GeForce RTX 2080 should be a lot (more or less 467%) faster with regards to AF than the GeForce GTX 950. (explain)

GeForce RTX 2080		278760 Mtexels/sec
GeForce GTX 950		49152 Mtexels/sec
	Difference: 229608 (467%)

Pixel Rate

The GeForce RTX 2080 should be quite a bit (more or less 196%) more effective at AA than the GeForce GTX 950, and should be able to handle higher screen resolutions without slowing down too much. (explain)

GeForce RTX 2080		96960 Mpixels/sec
GeForce GTX 950		32768 Mpixels/sec
	Difference: 64192 (196%)

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 max amount of data (in units of megabytes per second) that can be transferred over the external memory interface in a second. It's worked out by multiplying the interface width by its memory clock speed. If it uses DDR type memory, the result should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card can possibly write to its local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the amount of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate also depends on lots of other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the max fill rate.
