Theoretically speaking, the GeForce RTX 3090 will be 1564% quicker than the GeForce 8800 GT 512MB in general, because of its greater data rate. (explain)

GeForce RTX 3090		958668 MB/sec
GeForce 8800 GT 512MB		57600 MB/sec
	Difference: 901068 (1564%)

Texel Rate

The GeForce RTX 3090 should be quite a bit (more or less 1262%) better at AF than the GeForce 8800 GT 512MB. (explain)

GeForce RTX 3090		457560 Mtexels/sec
GeForce 8800 GT 512MB		33600 Mtexels/sec
	Difference: 423960 (1262%)

Pixel Rate

The GeForce RTX 3090 should be a lot (more or less 1528%) faster with regards to FSAA than the GeForce 8800 GT 512MB, and will be capable of handling higher screen resolutions while still performing well. (explain)

GeForce RTX 3090		156240 Mpixels/sec
GeForce 8800 GT 512MB		9600 Mpixels/sec
	Difference: 146640 (1528%)

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 max amount of information (counted in megabytes per second) that can be moved past the external memory interface in one second. The number is worked out by multiplying the card's bus width by its memory speed. If the card has DDR type memory, it must be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the bandwidth is, the faster 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 can be processed 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 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 maximum number of pixels the video card can possibly record to its local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate also depends on many other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
