GeForce GTX 1050 3GB		75 Watts
GeForce 9800 GT 1GB		105 Watts
	Difference: 30 Watts (40%)

Memory Bandwidth

Theoretically speaking, the GeForce GTX 1050 3GB will be 49% faster than the GeForce 9800 GT 1GB in general, because of its higher bandwidth. (explain)

GeForce GTX 1050 3GB		86016 MB/sec
GeForce 9800 GT 1GB		57600 MB/sec
	Difference: 28416 (49%)

Texel Rate

The GeForce GTX 1050 3GB is quite a bit (about 99%) faster with regards to texture filtering than the GeForce 9800 GT 1GB. (explain)

GeForce GTX 1050 3GB		66816 Mtexels/sec
GeForce 9800 GT 1GB		33600 Mtexels/sec
	Difference: 33216 (99%)

Pixel Rate

The GeForce GTX 1050 3GB will be quite a bit (more or less 248%) faster with regards to AA than the GeForce 9800 GT 1GB, and should be able to handle higher resolutions without losing too much performance. (explain)

GeForce GTX 1050 3GB		33408 Mpixels/sec
GeForce 9800 GT 1GB		9600 Mpixels/sec
	Difference: 23808 (248%)

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 maximum amount of data (counted in MB per second) that can be transported past the external memory interface in a second. It's worked out by multiplying the bus width by the speed of its memory. If it uses DDR type memory, the result should be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the bandwidth is, the faster 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 amount of texture map elements (texels) that are processed per second. This number is worked out by multiplying the total amount of texture units by the core clock speed of the chip. The higher this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip could possibly write to the local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the number of colour ROPs by the the card's clock speed. 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 is also dependant on quite a few other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
