GeForce GTX 480 vs Radeon RX 6950 XT

Intro

Compare all that to the Radeon RX 6950 XT, which features a GPU core clock speed of 1925 MHz, and 16384 MB of GDDR6 memory set to run at 2250 MHz through a 256-bit bus. It also is made up of 5120 Stream Processors, 320 TAUs, and 128 ROPs.

The Radeon RX 6950 XT is much (more or less 1367%) faster with regards to AF than the GeForce GTX 480. (explain)

Radeon RX 6950 XT		616000 Mtexels/sec
GeForce GTX 480		42000 Mtexels/sec
	Difference: 574000 (1367%)

Pixel Rate

The Radeon RX 6950 XT should be much (approximately 633%) better at full screen anti-aliasing than the GeForce GTX 480, and also will be capable of handling higher screen resolutions without losing too much performance. (explain)

Radeon RX 6950 XT		246400 Mpixels/sec
GeForce GTX 480		33600 Mpixels/sec
	Difference: 212800 (633%)

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 maximum amount of data (counted in megabytes per second) that can be moved across the external memory interface in a second. It's worked out by multiplying the card's 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 bandwidth is, the better 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 figure is calculated by multiplying the total amount of texture units of the card by the core clock speed of the chip. The higher the texel rate, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card can 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 - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate also depends on lots of other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
