GeForce RTX 3070 vs Radeon RX 6800

Intro

Compare all of that to the Radeon RX 6800, which makes use of a 7 nm design. AMD has set the core frequency at 1700 MHz. The GDDR6 memory works at a speed of 2000 MHz on this specific card. It features 3840 SPUs as well as 240 TAUs and 96 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

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 little 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 quite a bit (about 48%) faster with regards to texture filtering than the GeForce RTX 3070. (explain)

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

Pixel Rate

If using high levels of AA is important to you, then the Radeon RX 6800 is the winner, though only just barely. (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 max amount of data (in units of megabytes per second) that can be transported across the external memory interface in a second. It's worked out by multiplying the card's interface width by its memory speed. In the case of DDR memory, it must be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the card's 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 number of texture map elements (texels) that can be applied per second. This figure is calculated by multiplying the total amount of texture units of the card by the core speed of the chip. The better the texel rate, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip could possibly record to its local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - aka 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, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
