GeForce RTX 2070 vs Radeon RX 6800

Intro

Compare all that to the Radeon RX 6800, which uses a 7 nm design. AMD has clocked the core frequency at 1700 MHz. The GDDR6 memory runs at a frequency of 2000 MHz on this specific model. It features 3840 SPUs as well as 240 Texture Address Units and 96 Rasterization Operator Units.

GeForce RTX 2070		458752 MB/sec
	Difference: 65536 (14%)

Texel Rate

The Radeon RX 6800 should be quite a bit (more or less 101%) better at AF than the GeForce RTX 2070. (explain)

Radeon RX 6800		408000 Mtexels/sec
GeForce RTX 2070		203040 Mtexels/sec
	Difference: 204960 (101%)

Pixel Rate

The Radeon RX 6800 will be much (approximately 81%) faster with regards to full screen anti-aliasing than the GeForce RTX 2070, and able to handle higher screen resolutions without losing too much performance. (explain)

Radeon RX 6800		163200 Mpixels/sec
GeForce RTX 2070		90240 Mpixels/sec
	Difference: 72960 (81%)

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 (counted in MB per second) that can be moved past the external memory interface in a second. It is worked out by multiplying the card's interface width by the speed of its memory. If the card has DDR RAM, the result should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, 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 number of texture units by the core clock speed of the chip. The better the texel rate, the better the graphics 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 maximum number of pixels that the graphics card could possibly record to the local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of colour ROPs by the clock 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 quite a few other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
