GeForce 8600 GT 512MB DDR2		47 Watts
Radeon RX 6800		250 Watts
	Difference: 203 Watts (432%)

Memory Bandwidth

In theory, the Radeon RX 6800 is 3996% quicker than the GeForce 8600 GT 512MB DDR2 overall, due to its greater bandwidth. (explain)

Radeon RX 6800		524288 MB/sec
GeForce 8600 GT 512MB DDR2		12800 MB/sec
	Difference: 511488 (3996%)

Texel Rate

The Radeon RX 6800 will be a lot (more or less 4622%) more effective at AF than the GeForce 8600 GT 512MB DDR2. (explain)

Radeon RX 6800		408000 Mtexels/sec
GeForce 8600 GT 512MB DDR2		8640 Mtexels/sec
	Difference: 399360 (4622%)

Pixel Rate

The Radeon RX 6800 will be a lot (about 3678%) more effective at FSAA than the GeForce 8600 GT 512MB DDR2, and also should be capable of handling higher screen resolutions without losing too much performance. (explain)

Radeon RX 6800		163200 Mpixels/sec
GeForce 8600 GT 512MB DDR2		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 maximum amount of information (measured in MB per second) that can be transported over the external memory interface in one second. The number is worked out by multiplying the bus width by the speed of its memory. In the case of DDR memory, it should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card can possibly write to the local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate also depends on many other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the max fill rate.
