GeForce GTX 580		192384 MB/sec
	Difference: 397440 (207%)

Texel Rate

The Radeon RX 6950 XT will be quite a bit (about 1147%) more effective at anisotropic filtering than the GeForce GTX 580. (explain)

Radeon RX 6950 XT		616000 Mtexels/sec
GeForce GTX 580		49408 Mtexels/sec
	Difference: 566592 (1147%)

Pixel Rate

The Radeon RX 6950 XT will be much (about 565%) more effective at full screen anti-aliasing than the GeForce GTX 580, and should be able to handle higher screen resolutions without losing too much performance. (explain)

Radeon RX 6950 XT		246400 Mpixels/sec
GeForce GTX 580		37056 Mpixels/sec
	Difference: 209344 (565%)

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 information (counted in MB per second) that can be transported past the external memory interface in one second. The number is worked out by multiplying the card's interface width by the speed of its memory. In the case of DDR type memory, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the bandwidth is, the faster the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied per 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 handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.

Pixel Rate: Pixel rate is the maximum number of pixels the video card could possibly record to its local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the amount of ROPs 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 output rate also depends on quite a few other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
