GeForce GTX 650 Ti 2GB		86400 MB/sec
	Difference: 19328 (22%)

Texel Rate

The GeForce GTX 650 Ti 2GB should be much (about 21%) faster with regards to AF than the GeForce GTX 950. (explain)

GeForce GTX 650 Ti 2GB		59392 Mtexels/sec
GeForce GTX 950		49152 Mtexels/sec
	Difference: 10240 (21%)

Pixel Rate

The GeForce GTX 950 is much (more or less 121%) more effective at AA than the GeForce GTX 650 Ti 2GB, and will be able to handle higher screen resolutions without losing too much performance. (explain)

GeForce GTX 950		32768 Mpixels/sec
GeForce GTX 650 Ti 2GB		14848 Mpixels/sec
	Difference: 17920 (121%)

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 max amount of data (measured in megabytes per second) that can be transferred past the external memory interface in a second. It is worked out by multiplying the card's interface width by its memory speed. In the case of DDR RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the faster 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 are applied in one second. This figure is worked out by multiplying the total texture units by the core speed of the chip. The better this number, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.

Pixel Rate: Pixel rate is the most pixels the video card could possibly record to the local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate also depends 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.
