GeForce GTX 950M		32000 MB/sec
	Difference: 25600 (80%)

Texel Rate

The GeForce GTX 950M is a little bit (approximately 9%) faster with regards to AF than the GeForce 9800 GT 512MB. (explain)

GeForce GTX 950M		36560 Mtexels/sec
GeForce 9800 GT 512MB		33600 Mtexels/sec
	Difference: 2960 (9%)

Pixel Rate

The GeForce GTX 950M will be much (more or less 52%) more effective at AA than the GeForce 9800 GT 512MB, and also should be able to handle higher screen resolutions more effectively. (explain)

GeForce GTX 950M		14624 Mpixels/sec
GeForce 9800 GT 512MB		9600 Mpixels/sec
	Difference: 5024 (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 largest amount of data (counted in MB per second) that can be moved across the external memory interface in a second. It's calculated by multiplying the card's interface width by its memory clock speed. In the case of DDR type memory, it must be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are processed per second. This is calculated by multiplying the total amount of texture units by the core clock speed of the chip. The better the texel rate, the better the video 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 maximum amount of pixels the graphics card could possibly record to its local memory in one second - measured in millions of pixels per second. The figure is calculated 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 fill rate also depends on quite a few other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the max fill rate.
