GeForce RTX 3070 vs Radeon RX 6800

Intro

The GeForce RTX 3070 comes with a core clock frequency of 1500 MHz and a GDDR6 memory speed of 1750 MHz. It also features a 256-bit memory bus, and uses a 8 nm design. It is made up of 5888 SPUs, 184 Texture Address Units, and 96 ROPs.

Compare all of that 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 particular card. It features 3840 SPUs as well as 240 Texture Address Units and 96 ROPs.

GeForce RTX 3070 (Unknown) MB/sec
Difference: 524288 (-100%)

Texel Rate

The Radeon RX 6800 will be a lot (approximately 48%) faster with regards to AF than the GeForce RTX 3070. (explain)

Radeon RX 6800 408000 Mtexels/sec
GeForce RTX 3070 276000 Mtexels/sec
Difference: 132000 (48%)

Pixel Rate

The Radeon RX 6800 will be a small bit (approximately 13%) better at full screen anti-aliasing than the GeForce RTX 3070, and will be able to handle higher screen resolutions without losing too much performance. (explain)

Radeon RX 6800 163200 Mpixels/sec
GeForce RTX 3070 144000 Mpixels/sec
Difference: 19200 (13%)

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 MB per second) that can be transported across the external memory interface in a second. It is calculated by multiplying the bus width by the speed of its memory. If the card has DDR type memory, the result should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the memory bandwidth, the faster 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 processed per second. This figure is worked out by multiplying the total number of texture units of the card by the core clock 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 per second.

Pixel Rate: Pixel rate is the most pixels that the graphics card can possibly record to the local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate is also dependant on lots of other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
