GeForce RTX 4070 Ti vs Radeon RX 6800 XT

Intro

Compare all of that to the Radeon RX 6800 XT, which features clock speeds of 1825 MHz on the GPU, and 2000 MHz on the 16384 MB of GDDR6 memory. It features 4608 SPUs along with 288 Texture Address Units and 128 Rasterization Operator Units.

GeForce RTX 4070 Ti		516096 MB/sec
	Difference: 8192 (2%)

Texel Rate

The GeForce RTX 4070 Ti will be a little bit (more or less 5%) better at anisotropic filtering than the Radeon RX 6800 XT. (explain)

GeForce RTX 4070 Ti		554400 Mtexels/sec
Radeon RX 6800 XT		525600 Mtexels/sec
	Difference: 28800 (5%)

Pixel Rate

The Radeon RX 6800 XT is quite a bit (about 26%) more effective at full screen anti-aliasing than the GeForce RTX 4070 Ti, and also should be able to handle higher screen resolutions more effectively. (explain)

Radeon RX 6800 XT		233600 Mpixels/sec
GeForce RTX 4070 Ti		184800 Mpixels/sec
	Difference: 48800 (26%)

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 data (measured in megabytes per second) that can be moved across the external memory interface in one second. The number is calculated by multiplying the bus width by the speed of its memory. If the card has DDR type RAM, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the card's 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 number of texture map elements (texels) that can be applied per second. This figure is calculated by multiplying the total number of texture units of the card by the core clock speed of the chip. The better this number, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card can possibly write to the local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate also depends on quite a few other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
