Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce 8800 GTS (G80) 640MB		143 Watts
GeForce RTX 2070		175 Watts
	Difference: 32 Watts (22%)

Memory Bandwidth

In theory, the GeForce RTX 2070 is 624% quicker than the GeForce 8800 GTS (G80) 640MB overall, because of its higher bandwidth. (explain)

GeForce RTX 2070		458752 MB/sec
GeForce 8800 GTS (G80) 640MB		63360 MB/sec
	Difference: 395392 (624%)

Texel Rate

The GeForce RTX 2070 will be quite a bit (more or less 725%) better at texture filtering than the GeForce 8800 GTS (G80) 640MB. (explain)

GeForce RTX 2070		203040 Mtexels/sec
GeForce 8800 GTS (G80) 640MB		24624 Mtexels/sec
	Difference: 178416 (725%)

Pixel Rate

If running with high levels of AA is important to you, then the GeForce RTX 2070 is superior to the GeForce 8800 GTS (G80) 640MB, and very much so. (explain)

GeForce RTX 2070		90240 Mpixels/sec
GeForce 8800 GTS (G80) 640MB		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 largest amount of data (measured in MB per second) that can be transported past the external memory interface within a second. The number is worked out by multiplying the card's interface width by its memory clock speed. If the card has DDR RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are applied per second. This figure is worked out by multiplying the total texture units of the card by the core clock speed of the chip. The higher this number, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second.

Pixel Rate: Pixel rate is the most pixels that the graphics chip could possibly write to the local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate also depends on many other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the max fill rate.
