Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce 9600 GSO 768MB		84 Watts
GeForce RTX 2080		215 Watts
	Difference: 131 Watts (156%)

Memory Bandwidth

In theory, the GeForce RTX 2080 is 1095% faster than the GeForce 9600 GSO 768MB in general, because of its higher bandwidth. (explain)

GeForce RTX 2080		458752 MB/sec
GeForce 9600 GSO 768MB		38400 MB/sec
	Difference: 420352 (1095%)

Texel Rate

The GeForce RTX 2080 should be quite a bit (about 956%) more effective at anisotropic filtering than the GeForce 9600 GSO 768MB. (explain)

GeForce RTX 2080		278760 Mtexels/sec
GeForce 9600 GSO 768MB		26400 Mtexels/sec
	Difference: 252360 (956%)

Pixel Rate

The GeForce RTX 2080 will be much (approximately 1369%) faster with regards to full screen anti-aliasing than the GeForce 9600 GSO 768MB, and also able to handle higher resolutions without slowing down too much. (explain)

GeForce RTX 2080		96960 Mpixels/sec
GeForce 9600 GSO 768MB		6600 Mpixels/sec
	Difference: 90360 (1369%)

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 information (measured in megabytes per second) that can be transferred across the external memory interface in a second. It's worked out by multiplying the card's bus width by its memory clock speed. In the case of DDR RAM, it must be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the card's memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are applied per second. This figure is calculated by multiplying the total texture units of the card by the core 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 processed in a second.

Pixel Rate: Pixel rate is the most pixels the video card can possibly write to its local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate also depends on lots of other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the max fill rate.
