GeForce RTX 3070 vs Radeon RX 6800 XT

Intro

Compare all that to the Radeon RX 6800 XT, which has a core clock speed of 1825 MHz and a GDDR6 memory frequency of 2000 MHz. It also features a 256-bit memory bus, and makes use of a 7 nm design. It features 4608 SPUs, 288 Texture Address Units, and 128 ROPs.

GeForce RTX 3070		276000 Mtexels/sec
	Difference: 249600 (90%)

Pixel Rate

The Radeon RX 6800 XT will be much (about 62%) better at FSAA than the GeForce RTX 3070, and also able to handle higher resolutions more effectively. (explain)

Radeon RX 6800 XT		233600 Mpixels/sec
GeForce RTX 3070		144000 Mpixels/sec
	Difference: 89600 (62%)

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 largest amount of data (measured in megabytes per second) that can be moved over the external memory interface within a second. The number is calculated by multiplying the card's bus width by the speed of its memory. If it uses DDR memory, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the bandwidth is, the better the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied per second. This number 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 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 most pixels the graphics card could possibly write to its local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the number of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate is also dependant on lots of other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
