GeForce RTX 3070 vs Radeon RX 6900 XT

Intro

Compare those specifications to the Radeon RX 6900 XT, which uses a 7 nm design. AMD has set the core speed at 1825 MHz. The GDDR6 memory works at a speed of 2000 MHz on this model. It features 5120 SPUs as well as 320 TAUs 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

In theory, the Radeon RX 6900 XT will be -100% faster than the GeForce RTX 3070 in general, because of its greater bandwidth. (explain)

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

Texel Rate

The Radeon RX 6900 XT will be a lot (approximately 112%) better at texture filtering than the GeForce RTX 3070. (explain)

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

Pixel Rate

The Radeon RX 6900 XT should be a lot (approximately 62%) better at AA than the GeForce RTX 3070, and also will be capable of handling higher resolutions better. (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 maximum amount of data (counted in MB per second) that can be transferred across the external memory interface within a second. The number is calculated by multiplying the card's interface width by the speed of its memory. If it uses DDR type memory, it must be multiplied by 2 again. If 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 texture map elements (texels) that can be applied in one second. This figure 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 handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.

Pixel Rate: Pixel rate is the maximum amount of pixels the video card can possibly write to its local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the amount of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate also depends on many other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
