GeForce RTX 3070 Ti vs Radeon RX 6800

Intro

Compare those specs to the Radeon RX 6800, which uses a 7 nm design. AMD has set the core speed at 1700 MHz. The GDDR6 RAM runs at a speed of 2000 MHz on this model. It features 3840 SPUs as well as 240 TAUs and 96 ROPs.

Radeon RX 6800		524288 MB/sec
	Difference: 98611 (19%)

Texel Rate

The Radeon RX 6800 will be quite a bit (approximately 35%) faster with regards to texture 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

If running with a high resolution is important to you, then the Radeon RX 6800 is superior to the GeForce RTX 3070 Ti, but not by far. (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: Bandwidth is the maximum amount of information (counted in megabytes per second) that can be transported over the external memory interface in one second. It is calculated by multiplying the interface width by the speed of its memory. In the case of DDR type RAM, it should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the card's memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are applied per 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 card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card could possibly write to the local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the amount of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate is also dependant on lots of other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
