Radeon HD 7790		96000 MB/sec
	Difference: 838297 (873%)

Texel Rate

The GeForce RTX 3080 Ti is quite a bit (approximately 680%) better at texture filtering than the Radeon HD 7790. (explain)

GeForce RTX 3080 Ti		436800 Mtexels/sec
Radeon HD 7790		56000 Mtexels/sec
	Difference: 380800 (680%)

Pixel Rate

If running with high levels of AA is important to you, then the GeForce RTX 3080 Ti is superior to the Radeon HD 7790, and very much so. (explain)

GeForce RTX 3080 Ti		152880 Mpixels/sec
Radeon HD 7790		16000 Mpixels/sec
	Difference: 136880 (856%)

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 data (in units of megabytes per second) that can be transported past the external memory interface in a second. It's worked out by multiplying the interface width by its memory clock speed. If the card has DDR RAM, the result should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card could possibly write to the local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the amount of Render Output Units by the the core 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 output rate is also dependant on quite a few other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
