In theory, the GeForce RTX 2080 Ti should be 995% faster than the GeForce 8800 GT 512MB overall, because of its greater bandwidth. (explain)

GeForce RTX 2080 Ti		630784 MB/sec
GeForce 8800 GT 512MB		57600 MB/sec
	Difference: 573184 (995%)

Texel Rate

The GeForce RTX 2080 Ti is quite a bit (approximately 993%) more effective at AF than the GeForce 8800 GT 512MB. (explain)

GeForce RTX 2080 Ti		367200 Mtexels/sec
GeForce 8800 GT 512MB		33600 Mtexels/sec
	Difference: 333600 (993%)

Pixel Rate

The GeForce RTX 2080 Ti will be much (approximately 1138%) more effective at FSAA than the GeForce 8800 GT 512MB, and able to handle higher resolutions while still performing well. (explain)

GeForce RTX 2080 Ti		118800 Mpixels/sec
GeForce 8800 GT 512MB		9600 Mpixels/sec
	Difference: 109200 (1138%)

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 transferred over the external memory interface within a second. It is calculated by multiplying the card's interface width by the speed of its memory. If it uses DDR RAM, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the faster the card will be in general. It especially helps with AA, HDR and high resolutions.

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

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