GeForce 8800 GTS (G80) 320MB		143 Watts
GeForce RTX 2070		175 Watts
	Difference: 32 Watts (22%)

Memory Bandwidth

Theoretically, the GeForce RTX 2070 should be quite a bit faster than the GeForce 8800 GTS (G80) 320MB in general. (explain)

GeForce RTX 2070		458752 MB/sec
GeForce 8800 GTS (G80) 320MB		63360 MB/sec
	Difference: 395392 (624%)

Texel Rate

The GeForce RTX 2070 is quite a bit (approximately 725%) better at texture filtering than the GeForce 8800 GTS (G80) 320MB. (explain)

GeForce RTX 2070		203040 Mtexels/sec
GeForce 8800 GTS (G80) 320MB		24624 Mtexels/sec
	Difference: 178416 (725%)

Pixel Rate

The GeForce RTX 2070 is much (approximately 780%) better at AA than the GeForce 8800 GTS (G80) 320MB, and should be able to handle higher screen resolutions without losing too much performance. (explain)

GeForce RTX 2070		90240 Mpixels/sec
GeForce 8800 GTS (G80) 320MB		10260 Mpixels/sec
	Difference: 79980 (780%)

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

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card can possibly record to its local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate is also dependant on many other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
