GeForce RTX 3070 vs Radeon RX 6800

Intro

The GeForce RTX 3070 has a core clock speed of 1500 MHz and a GDDR6 memory frequency of 1750 MHz. It also makes use of a 256-bit memory bus, and makes use of a 8 nm design. It features 5888 SPUs, 184 Texture Address Units, and 96 Raster Operation Units.

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

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce RTX 3070 220 Watts
Radeon RX 6800 250 Watts
Difference: 30 Watts (14%)

Memory Bandwidth

Theoretically speaking, the Radeon RX 6800 will be -100% quicker than the GeForce RTX 3070 in general, due to its higher bandwidth. (explain)

Radeon RX 6800 524288 MB/sec
GeForce RTX 3070 (Unknown) MB/sec
Difference: 524288 (-100%)

Texel Rate

The Radeon RX 6800 is quite a bit (about 48%) better at 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 is a bit (approximately 13%) better at anti-aliasing than the GeForce RTX 3070, and capable of handling higher screen resolutions while still performing well. (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 max amount of information (in units of megabytes per second) that can be transported across the external memory interface within a second. It's worked out by multiplying the card's interface width by its memory clock 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 anti-aliasing, High Dynamic Range and higher screen resolutions.

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

Pixel Rate: Pixel rate is the most pixels that the graphics chip could possibly write to the local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the number of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate is also dependant on many other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
