GeForce RTX 4070 Ti vs Radeon RX 6950 XT

Intro

Compare all that to the Radeon RX 6950 XT, which has GPU clock speed of 1925 MHz, and 16384 MB of GDDR6 RAM set to run at 2250 MHz through a 256-bit bus. It also features 5120 Stream Processors, 320 Texture Address Units, and 128 Raster Operation Units.

Texel Rate

The Radeon RX 6950 XT will be a little bit (about 11%) more effective at anisotropic filtering than the GeForce RTX 4070 Ti. (explain)

Radeon RX 6950 XT		616000 Mtexels/sec
GeForce RTX 4070 Ti		554400 Mtexels/sec
	Difference: 61600 (11%)

Pixel Rate

The Radeon RX 6950 XT should be much (more or less 33%) more effective at full screen anti-aliasing than the GeForce RTX 4070 Ti, and able to handle higher screen resolutions while still performing well. (explain)

Radeon RX 6950 XT		246400 Mpixels/sec
GeForce RTX 4070 Ti		184800 Mpixels/sec
	Difference: 61600 (33%)

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 information (measured in megabytes per second) that can be moved across the external memory interface within a second. The number is calculated by multiplying the card's bus width by its memory clock speed. If it uses DDR type RAM, the result should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the bandwidth is, the faster 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 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 processed per second.

Pixel Rate: Pixel rate is the most pixels that the graphics card could possibly write to its local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate is also dependant on lots of other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
