GeForce RTX 3070 Ti vs Radeon RX 6800

Intro

Compare those specifications to the Radeon RX 6800, which comes with core speeds of 1700 MHz on the GPU, and 2000 MHz on the 16384 MB of GDDR6 RAM. It features 3840 SPUs as well as 240 TAUs and 96 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon RX 6800		250 Watts
GeForce RTX 3070 Ti		290 Watts
	Difference: 40 Watts (16%)

Memory Bandwidth

Theoretically speaking, the GeForce RTX 3070 Ti will be 19% faster than the Radeon RX 6800 in general, because of its higher data rate. (explain)

GeForce RTX 3070 Ti		622899 MB/sec
Radeon RX 6800		524288 MB/sec
	Difference: 98611 (19%)

Texel Rate

The Radeon RX 6800 should be much (more or less 35%) more effective at anisotropic filtering than the GeForce RTX 3070 Ti. (explain)

Radeon RX 6800		408000 Mtexels/sec
GeForce RTX 3070 Ti		302400 Mtexels/sec
	Difference: 105600 (35%)

Pixel Rate

The Radeon RX 6800 should be a small bit (approximately 8%) better at anti-aliasing than the GeForce RTX 3070 Ti, and also should be able to handle higher screen resolutions more effectively. (explain)

Radeon RX 6800		163200 Mpixels/sec
GeForce RTX 3070 Ti		151200 Mpixels/sec
	Difference: 12000 (8%)

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 information (counted in MB per second) that can be moved over the external memory interface in a second. The number is worked out by multiplying the interface width by its memory speed. If it uses DDR type memory, it should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the memory bandwidth, the faster 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 are processed in one second. This figure is worked out by multiplying the total number of texture units by the core clock speed of the chip. The higher this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second.

Pixel Rate: Pixel rate is the most pixels that the graphics chip can possibly record to its local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate is also dependant on many other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
