GeForce RTX 4070 Ti vs Radeon RX 6950 XT

Intro

Compare those specs to the Radeon RX 6950 XT, which has GPU core speed of 1925 MHz, and 16384 MB of GDDR6 RAM set to run at 2250 MHz through a 256-bit bus. It also is made up of 5120 Stream Processors, 320 TAUs, and 128 Raster Operation Units.

The Radeon RX 6950 XT is a little bit (more or less 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 (about 33%) better at full screen anti-aliasing than the GeForce RTX 4070 Ti, and will be able to handle higher resolutions more effectively. (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: Memory bandwidth is the maximum amount of information (counted in megabytes per second) that can be moved over the external memory interface in a second. The number is worked out by multiplying the card's bus width by its memory speed. If it uses DDR 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 processed in one second. This is worked out by multiplying the total number of texture units of the card by the core speed of the chip. The higher this number, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card can possibly record to the local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. 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 get to the max fill rate.
