The GeForce RTX 4090 is much (more or less 3306%) more effective at texture filtering than the GeForce 8800 GT 512MB. (explain)

GeForce RTX 4090		1144320 Mtexels/sec
GeForce 8800 GT 512MB		33600 Mtexels/sec
	Difference: 1110720 (3306%)

Pixel Rate

The GeForce RTX 4090 should be a lot (about 3998%) better at FSAA than the GeForce 8800 GT 512MB, and will be capable of handling higher screen resolutions better. (explain)

GeForce RTX 4090		393360 Mpixels/sec
GeForce 8800 GT 512MB		9600 Mpixels/sec
	Difference: 383760 (3998%)

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 max amount of data (in units of megabytes per second) that can be moved past the external memory interface in a second. It is worked out by multiplying the card's interface width by its memory clock speed. In the case of DDR RAM, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the memory bandwidth, 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 amount of texture map elements (texels) that can be processed per second. This number is worked out by multiplying the total amount of texture units by the core speed of the chip. The better the texel rate, the better the video card will be at handling 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 the graphics card can possibly write to its local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the number of colour ROPs by the the core speed of the card. 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 rate is also dependant on many other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
