GeForce RTX 2070		175 Watts
	Difference: 128 Watts (272%)

Memory Bandwidth

As far as performance goes, the GeForce RTX 2070 should in theory be a lot better than the GeForce 8600 GT 1GB GDDR3 overall. (explain)

GeForce RTX 2070		458752 MB/sec
GeForce 8600 GT 1GB GDDR3		22400 MB/sec
	Difference: 436352 (1948%)

Texel Rate

The GeForce RTX 2070 should be quite a bit (approximately 2250%) better at AF than the GeForce 8600 GT 1GB GDDR3. (explain)

GeForce RTX 2070		203040 Mtexels/sec
GeForce 8600 GT 1GB GDDR3		8640 Mtexels/sec
	Difference: 194400 (2250%)

Pixel Rate

The GeForce RTX 2070 is quite a bit (approximately 1989%) faster with regards to full screen anti-aliasing than the GeForce 8600 GT 1GB GDDR3, and also will be able to handle higher screen resolutions without slowing down too much. (explain)

GeForce RTX 2070		90240 Mpixels/sec
GeForce 8600 GT 1GB GDDR3		4320 Mpixels/sec
	Difference: 85920 (1989%)

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 megabytes per second) that can be transferred across the external memory interface in a second. The number is worked out by multiplying the card's interface width by its memory speed. If it uses DDR type RAM, it must be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the most pixels the graphics card could possibly write to the local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the amount of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate is also dependant on lots of other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
