GeForce RTX 4070 Ti vs Radeon RX 6950 XT

Intro

Compare that to the Radeon RX 6950 XT, which has a GPU core clock 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 SPUs, 320 TAUs, and 128 Raster Operation Units.

	Difference: 73728 (14%)

Texel Rate

The Radeon RX 6950 XT should be a little bit (more or less 11%) better at texture 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 is much (about 33%) better at full screen anti-aliasing than the GeForce RTX 4070 Ti, and also will be 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 maximum amount of information (in units of MB per second) that can be moved over the external memory interface in one second. It is worked out by multiplying the card's bus width by the speed of its memory. If it uses DDR type memory, it must be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better 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 amount of texture map elements (texels) that can be processed in one second. This is calculated by multiplying the total amount of texture units by the core clock speed of the chip. The higher 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 number of pixels that the graphics chip could possibly write to its local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the number of colour ROPs by the the core clock speed. 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 is also dependant on quite a few other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
