GeForce RTX 3070 Ti vs Radeon RX 6950 XT

Intro

Compare that to the Radeon RX 6950 XT, which comes with a core clock speed of 1925 MHz and a GDDR6 memory frequency of 2250 MHz. It also uses a 256-bit bus, and makes use of a 7 nm design. It features 5120 SPUs, 320 TAUs, and 128 ROPs.

GeForce RTX 3070 Ti		290 Watts
Radeon RX 6950 XT		335 Watts
	Difference: 45 Watts (16%)

Memory Bandwidth

Theoretically speaking, the GeForce RTX 3070 Ti will be 6% faster than the Radeon RX 6950 XT overall, due to its higher bandwidth. (explain)

GeForce RTX 3070 Ti		622899 MB/sec
Radeon RX 6950 XT		589824 MB/sec
	Difference: 33075 (6%)

Texel Rate

The Radeon RX 6950 XT will be a lot (approximately 104%) better at anisotropic filtering than the GeForce RTX 3070 Ti. (explain)

Radeon RX 6950 XT		616000 Mtexels/sec
GeForce RTX 3070 Ti		302400 Mtexels/sec
	Difference: 313600 (104%)

Pixel Rate

If using a high screen resolution is important to you, then the Radeon RX 6950 XT is superior to the GeForce RTX 3070 Ti, and very much so. (explain)

Radeon RX 6950 XT		246400 Mpixels/sec
GeForce RTX 3070 Ti		151200 Mpixels/sec
	Difference: 95200 (63%)

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 max amount of data (in units of MB per second) that can be moved over the external memory interface in one second. The number is worked out by multiplying the bus width by its memory speed. If the card has DDR RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be applied in one second. This is worked out by multiplying the total amount of texture units by the core clock speed of the chip. The higher this number, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.

Pixel Rate: Pixel rate is the maximum number of pixels the video card could possibly record to its local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the number of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate is also dependant on many other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the max fill rate.
