GeForce RTX 3070 vs Radeon RX 6800

Intro

Compare all that to the Radeon RX 6800, which comes with GPU clock speed of 1700 MHz, and 16384 MB of GDDR6 memory set to run at 2000 MHz through a 256-bit bus. It also is made up of 3840 Stream Processors, 240 Texture Address Units, and 96 Raster Operation Units.

GeForce RTX 3070		220 Watts
Radeon RX 6800		250 Watts
	Difference: 30 Watts (14%)

Memory Bandwidth

As far as performance goes, the Radeon RX 6800 should in theory be a bit better than the GeForce RTX 3070 in general. (explain)

Radeon RX 6800		524288 MB/sec
GeForce RTX 3070		(Unknown) MB/sec
	Difference: 524288 (-100%)

Texel Rate

The Radeon RX 6800 should be much (approximately 48%) more effective at AF than the GeForce RTX 3070. (explain)

Radeon RX 6800		408000 Mtexels/sec
GeForce RTX 3070		276000 Mtexels/sec
	Difference: 132000 (48%)

Pixel Rate

The Radeon RX 6800 is a little bit (more or less 13%) more effective at FSAA than the GeForce RTX 3070, and capable of handling higher screen resolutions more effectively. (explain)

Radeon RX 6800		163200 Mpixels/sec
GeForce RTX 3070		144000 Mpixels/sec
	Difference: 19200 (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 (in units of MB per second) that can be transferred across the external memory interface in a second. It is calculated by multiplying the card's bus width by its memory speed. In the case of DDR memory, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed per second. This figure is worked out by multiplying the total amount 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 applied in a second.

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