GeForce 9800 GTX+		70400 MB/sec
	Difference: 15616 (22%)

Texel Rate

The GeForce GTX 1050 3GB should be a lot (more or less 41%) more effective at anisotropic filtering than the GeForce 9800 GTX+. (explain)

GeForce GTX 1050 3GB		66816 Mtexels/sec
GeForce 9800 GTX+		47232 Mtexels/sec
	Difference: 19584 (41%)

Pixel Rate

The GeForce GTX 1050 3GB will be quite a bit (approximately 183%) more effective at FSAA than the GeForce 9800 GTX+, and also will be able to handle higher resolutions while still performing well. (explain)

GeForce GTX 1050 3GB		33408 Mpixels/sec
GeForce 9800 GTX+		11808 Mpixels/sec
	Difference: 21600 (183%)

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 (in units of megabytes per second) that can be moved across the external memory interface within a second. It is calculated by multiplying the card's interface width by its memory clock speed. In the case of DDR type RAM, it should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the bandwidth is, 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 worked out by multiplying the total texture units of the card 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 applied in a second.

Pixel Rate: Pixel rate is the most pixels that the graphics card can possibly record to the local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the number of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate also depends on quite a few other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the max fill rate.
