GeForce RTX 4070 Ti vs Radeon RX 6800

Intro

Compare that to the Radeon RX 6800, which features core clock speeds of 1700 MHz on the GPU, and 2000 MHz on the 16384 MB of GDDR6 RAM. It features 3840 SPUs as well as 240 TAUs and 96 ROPs.

The GeForce RTX 4070 Ti is a lot (approximately 36%) faster with regards to AF than the Radeon RX 6800. (explain)

GeForce RTX 4070 Ti		554400 Mtexels/sec
Radeon RX 6800		408000 Mtexels/sec
	Difference: 146400 (36%)

Pixel Rate

If using a high screen resolution is important to you, then the GeForce RTX 4070 Ti is the winner, but only just. (explain)

GeForce RTX 4070 Ti		184800 Mpixels/sec
Radeon RX 6800		163200 Mpixels/sec
	Difference: 21600 (13%)

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 (measured in MB per second) that can be transferred across the external memory interface in one second. The number is calculated by multiplying the interface width by its memory clock speed. If it uses DDR type RAM, it must be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be applied in one second. This number is calculated 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 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 card could possibly record to its local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the amount of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate is also dependant on lots of other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
