GeForce 9800 GT 1GB		105 Watts
GeForce RTX 2080 SUPER		250 Watts
	Difference: 145 Watts (138%)

Memory Bandwidth

In theory, the GeForce RTX 2080 SUPER will be 782% quicker than the GeForce 9800 GT 1GB in general, because of its greater bandwidth. (explain)

GeForce RTX 2080 SUPER		507904 MB/sec
GeForce 9800 GT 1GB		57600 MB/sec
	Difference: 450304 (782%)

Texel Rate

The GeForce RTX 2080 SUPER is a lot (about 843%) better at anisotropic filtering than the GeForce 9800 GT 1GB. (explain)

GeForce RTX 2080 SUPER		316800 Mtexels/sec
GeForce 9800 GT 1GB		33600 Mtexels/sec
	Difference: 283200 (843%)

Pixel Rate

The GeForce RTX 2080 SUPER should be much (more or less 1000%) better at full screen anti-aliasing than the GeForce 9800 GT 1GB, and also capable of handling higher screen resolutions more effectively. (explain)

GeForce RTX 2080 SUPER		105600 Mpixels/sec
GeForce 9800 GT 1GB		9600 Mpixels/sec
	Difference: 96000 (1000%)

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 largest amount of data (measured in megabytes per second) that can be transferred past the external memory interface in one second. It's calculated by multiplying the card's interface width by the speed of its memory. If the card has DDR type RAM, it should be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the most pixels the graphics card can possibly write to its local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate is also dependant on lots of other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
