GeForce RTX 3070 vs Radeon RX 6900 XT

Intro

Compare all of that to the Radeon RX 6900 XT, which uses a 7 nm design. AMD has set the core speed at 1825 MHz. The GDDR6 RAM is set to run at a speed of 2000 MHz on this card. It features 5120 SPUs along with 320 Texture Address Units and 128 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce RTX 3070		220 Watts
Radeon RX 6900 XT		300 Watts
	Difference: 80 Watts (36%)

Memory Bandwidth

As far as performance goes, the Radeon RX 6900 XT should theoretically be just a bit superior to the GeForce RTX 3070 in general. (explain)

Radeon RX 6900 XT		524288 MB/sec
GeForce RTX 3070		(Unknown) MB/sec
	Difference: 524288 (-100%)

Texel Rate

The Radeon RX 6900 XT is much (about 112%) faster with regards to AF than the GeForce RTX 3070. (explain)

Radeon RX 6900 XT		584000 Mtexels/sec
GeForce RTX 3070		276000 Mtexels/sec
	Difference: 308000 (112%)

Pixel Rate

If running with high levels of AA is important to you, then the Radeon RX 6900 XT is superior to the GeForce RTX 3070, and very much so. (explain)

Radeon RX 6900 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: Memory bandwidth is the largest amount of information (measured in MB per second) that can be moved over the external memory interface within a second. The number is worked out by multiplying the interface width by the speed of its memory. If the card has DDR type memory, the result should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

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

Pixel Rate: Pixel rate is the most pixels that the graphics card could possibly record to its local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the amount of ROPs by the the core 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 output rate also depends on lots of other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the max fill rate.
