GeForce GTX 980 vs Radeon RX 6950 XT

Intro

Compare all that to the Radeon RX 6950 XT, which features a clock speed of 1925 MHz and a GDDR6 memory frequency of 2250 MHz. It also features a 256-bit bus, and makes use of a 7 nm design. It is made up of 5120 SPUs, 320 Texture Address Units, and 128 Raster Operation Units.

GeForce GTX 980		144128 Mtexels/sec
	Difference: 471872 (327%)

Pixel Rate

If using a high screen resolution is important to you, then the Radeon RX 6950 XT is superior to the GeForce GTX 980, and very much so. (explain)

Radeon RX 6950 XT		246400 Mpixels/sec
GeForce GTX 980		72064 Mpixels/sec
	Difference: 174336 (242%)

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 largest amount of information (counted in MB per second) that can be transported past the external memory interface within a second. The number is worked out by multiplying the interface width by its memory speed. If it uses DDR RAM, the result should be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be processed per second. This figure 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 card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card could possibly record to the local memory in one second - measured in millions of pixels per second. The number is worked out 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 outputting the pixels (image) to the screen. The actual pixel output rate also depends on quite a few other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
