GeForce GTX 1070 vs Radeon RX 6800

Intro

The GeForce GTX 1070 features a clock speed of 1506 MHz and a GDDR5 memory speed of 2000 MHz. It also uses a 256-bit memory bus, and uses a 16 nm design. It is comprised of 1920 SPUs, 120 TAUs, and 64 ROPs.

Compare all that to the Radeon RX 6800, which comes with core clock speeds of 1700 MHz on the GPU, and 2000 MHz on the 16384 MB of GDDR6 RAM. It features 3840 SPUs along with 240 Texture Address Units and 96 ROPs.

GeForce GTX 1070 150 Watts
Radeon RX 6800 250 Watts
Difference: 100 Watts (67%)

Memory Bandwidth

Theoretically speaking, the Radeon RX 6800 should perform much faster than the GeForce GTX 1070 in general. (explain)

Radeon RX 6800 524288 MB/sec
GeForce GTX 1070 262144 MB/sec
Difference: 262144 (100%)

Texel Rate

The Radeon RX 6800 will be quite a bit (about 126%) faster with regards to AF than the GeForce GTX 1070. (explain)

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

Pixel Rate

If using lots of anti-aliasing is important to you, then the Radeon RX 6800 is the winner, and very much so. (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 data (counted in MB per second) that can be moved over the external memory interface within a second. The number is worked out by multiplying the bus width by its memory speed. If it uses DDR RAM, it should be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be applied per second. This figure is worked out by multiplying the total texture units by the core clock speed of the chip. The higher the texel rate, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card could possibly record to the local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also called 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, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the max fill rate.
