GeForce GTX 1070 vs Radeon RX 6800

Intro

The GeForce GTX 1070 comes with a clock speed of 1506 MHz and a GDDR5 memory speed of 2000 MHz. It also makes use of a 256-bit bus, and uses a 16 nm design. It features 1920 SPUs, 120 Texture Address Units, and 64 Raster Operation Units.

Compare those specifications to the Radeon RX 6800, which has GPU core 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 Stream Processors, 240 TAUs, and 96 Raster Operation Units.

GeForce GTX 1070 262144 MB/sec
Difference: 262144 (100%)

Texel Rate

The Radeon RX 6800 is a lot (more or less 126%) better at AF than the GeForce GTX 1070. (explain)

Radeon RX 6800 408000 Mtexels/sec
GeForce GTX 1070 180720 Mtexels/sec
Difference: 227280 (126%)

Pixel Rate

The Radeon RX 6800 should be much (more or less 69%) better at anti-aliasing than the GeForce GTX 1070, and should be able to handle higher resolutions without slowing down too much. (explain)

Radeon RX 6800 163200 Mpixels/sec
GeForce GTX 1070 96384 Mpixels/sec
Difference: 66816 (69%)

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.

Memory Bandwidth: Bandwidth is the maximum amount of information (measured in megabytes per second) that can be moved past the external memory interface within a second. The number is worked out by multiplying the card's bus width by the speed of its memory. If it uses DDR type RAM, it must be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, 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 amount of texture map elements (texels) that can be applied in one second. This figure is calculated by multiplying the total amount of texture units of the card by the core speed of the chip. The better the texel rate, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second.

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card could possibly write to the local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate also depends on lots of other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
