Radeon R9 Nano		512000 MB/sec
	Difference: 77824 (15%)

Texel Rate

The Radeon RX 6950 XT should be a lot (approximately 141%) faster with regards to texture filtering than the Radeon R9 Nano. (explain)

Radeon RX 6950 XT		616000 Mtexels/sec
Radeon R9 Nano		256000 Mtexels/sec
	Difference: 360000 (141%)

Pixel Rate

The Radeon RX 6950 XT is a lot (about 285%) better at AA than the Radeon R9 Nano, and will be capable of handling higher screen resolutions without slowing down too much. (explain)

Radeon RX 6950 XT		246400 Mpixels/sec
Radeon R9 Nano		64000 Mpixels/sec
	Difference: 182400 (285%)

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 (measured in MB per second) that can be transferred across the external memory interface within a second. It is worked out by multiplying the bus width by its memory speed. If the card has DDR type RAM, the result should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the faster 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 are applied per second. This figure is calculated by multiplying the total number of texture units of the card by the core clock speed of the chip. The higher this number, the better the 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 can possibly write to the local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate also depends on lots of other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
