Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce 8600 GT 512MB DDR2		47 Watts
GeForce RTX 3070		220 Watts
	Difference: 173 Watts (368%)

Memory Bandwidth

In theory, the GeForce 8600 GT 512MB DDR2 is -100% quicker than the GeForce RTX 3070 overall, due to its greater data rate. (explain)

GeForce 8600 GT 512MB DDR2		12800 MB/sec
GeForce RTX 3070		(Unknown) MB/sec
	Difference: 12800 (-100%)

Texel Rate

The GeForce RTX 3070 will be quite a bit (approximately 3094%) more effective at AF than the GeForce 8600 GT 512MB DDR2. (explain)

GeForce RTX 3070		276000 Mtexels/sec
GeForce 8600 GT 512MB DDR2		8640 Mtexels/sec
	Difference: 267360 (3094%)

Pixel Rate

The GeForce RTX 3070 should be much (about 3233%) better at FSAA than the GeForce 8600 GT 512MB DDR2, and also should be capable of handling higher screen resolutions without slowing down too much. (explain)

GeForce RTX 3070		144000 Mpixels/sec
GeForce 8600 GT 512MB DDR2		4320 Mpixels/sec
	Difference: 139680 (3233%)

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 (counted in megabytes per second) that can be transported across the external memory interface within a second. The number is calculated by multiplying the interface width by its memory speed. If the card has DDR memory, the result should be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the card's memory bandwidth, the faster 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 number of texture map elements (texels) that can be applied per second. This number is worked out by multiplying the total amount of texture units of the card by the core speed of the chip. The higher the texel rate, the better the card will be at 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 could possibly record to the local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. 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 get to the maximum fill rate.
