GeForce RTX 3070 Ti vs Radeon RX 6800

Intro

Compare those specs to the Radeon RX 6800, which has a GPU core clock speed of 1700 MHz, and 16384 MB of GDDR6 RAM set to run at 2000 MHz through a 256-bit bus. It also is made up of 3840 SPUs, 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

The GeForce RTX 3070 Ti should in theory perform a little bit faster than the Radeon RX 6800 overall. (explain)

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

Texel Rate

The Radeon RX 6800 is a lot (about 35%) faster with regards to 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%) more effective at anti-aliasing than the GeForce RTX 3070 Ti, and also will be capable of handling higher resolutions while still performing well. (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 largest amount of information (counted in MB per second) that can be transferred across the external memory interface within a second. The number is worked out by multiplying the interface width by its memory clock speed. If the card has DDR memory, it should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the bandwidth is, the faster the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

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

Pixel Rate: Pixel rate is the most pixels the video card can possibly record to its local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the number of Raster Operations Pipelines by the clock 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 lots of other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
