GeForce 8600 GT 512MB DDR2 12800 MB/sec
Difference: 445952 (3484%)

Texel Rate

The GeForce RTX 2080 will be a lot (more or less 3126%) faster with regards to AF than the GeForce 8600 GT 512MB DDR2. (explain)

GeForce RTX 2080 278760 Mtexels/sec
GeForce 8600 GT 512MB DDR2 8640 Mtexels/sec
Difference: 270120 (3126%)

Pixel Rate

The GeForce RTX 2080 is quite a bit (about 2144%) faster with regards to anti-aliasing than the GeForce 8600 GT 512MB DDR2, and will be capable of handling higher resolutions more effectively. (explain)

GeForce RTX 2080 96960 Mpixels/sec
GeForce 8600 GT 512MB DDR2 4320 Mpixels/sec
Difference: 92640 (2144%)

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.

Memory Bandwidth: Bandwidth is the max amount of data (measured in megabytes per second) that can be moved over the external memory interface in a second. It is worked out by multiplying the bus width by its memory clock speed. If it uses DDR memory, the result should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR 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 amount of texture units of the card by the core speed of the chip. The higher the texel rate, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second.

Pixel Rate: Pixel rate is the most pixels that the graphics chip can possibly record to its local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate also depends on quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
