GeForce GTX 970 vs Radeon RX 6800

Intro

Compare all of that to the Radeon RX 6800, which features a clock frequency of 1700 MHz and a GDDR6 memory frequency of 2000 MHz. It also uses a 256-bit bus, and makes use of a 7 nm design. It is comprised of 3840 SPUs, 240 TAUs, and 96 ROPs.

GeForce GTX 970		224000 MB/sec
	Difference: 300288 (134%)

Texel Rate

The Radeon RX 6800 is much (approximately 274%) more effective at AF than the GeForce GTX 970. (explain)

Radeon RX 6800		408000 Mtexels/sec
GeForce GTX 970		109200 Mtexels/sec
	Difference: 298800 (274%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the Radeon RX 6800 is superior to the GeForce GTX 970, by far. (explain)

Radeon RX 6800		163200 Mpixels/sec
GeForce GTX 970		67200 Mpixels/sec
	Difference: 96000 (143%)

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 data (in units of megabytes per second) that can be transported past the external memory interface in one second. It's calculated by multiplying the card's interface width by its memory clock speed. In the case of DDR type memory, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are processed in one second. This number is worked out by multiplying the total number of texture units of the card by the core speed of the chip. The better the texel rate, the better the video 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 most pixels that the graphics chip could possibly record to the local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate is also dependant on lots of other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
