GeForce 8600 GT 1GB GDDR3		47 Watts
Radeon RX 6800		250 Watts
	Difference: 203 Watts (432%)

Memory Bandwidth

In theory, the Radeon RX 6800 is 2241% faster than the GeForce 8600 GT 1GB GDDR3 overall, due to its greater bandwidth. (explain)

Radeon RX 6800		524288 MB/sec
GeForce 8600 GT 1GB GDDR3		22400 MB/sec
	Difference: 501888 (2241%)

Texel Rate

The Radeon RX 6800 will be much (more or less 4622%) better at anisotropic filtering than the GeForce 8600 GT 1GB GDDR3. (explain)

Radeon RX 6800		408000 Mtexels/sec
GeForce 8600 GT 1GB GDDR3		8640 Mtexels/sec
	Difference: 399360 (4622%)

Pixel Rate

The Radeon RX 6800 is much (about 3678%) more effective at AA than the GeForce 8600 GT 1GB GDDR3, and also should be capable of handling higher resolutions better. (explain)

Radeon RX 6800		163200 Mpixels/sec
GeForce 8600 GT 1GB GDDR3		4320 Mpixels/sec
	Difference: 158880 (3678%)

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 largest amount of information (measured in MB per second) that can be transported past the external memory interface in a second. The number is worked out by multiplying the interface width by the speed of its memory. If the card has DDR type memory, it must be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, 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 amount of texture map elements (texels) that are applied per second. This is calculated by multiplying the total texture units of the card by the core clock speed of the chip. The higher the texel rate, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second.

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card can possibly write to its local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate also depends on lots of other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
