GeForce RTX 2070 vs GeForce RTX 2080

Intro

The GeForce RTX 2070 has a core clock frequency of 1410 MHz and a GDDR6 memory speed of 14 MHz. It also features a 256-bit memory bus, and makes use of a 12 nm design. It features 2304 SPUs, 144 TAUs, and 64 Raster Operation Units.

Compare those specs to the GeForce RTX 2080, which uses a 12 nm design. nVidia has set the core frequency at 1515 MHz. The GDDR6 RAM runs at a frequency of 14 MHz on this specific card. It features 2944 SPUs as well as 184 Texture Address Units and 64 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce RTX 2070 175 Watts
GeForce RTX 2080 215 Watts
Difference: 40 Watts (23%)

Memory Bandwidth

Both cards have exactly the same bandwidth, so theoretically they should perform the same. (explain)

Texel Rate

The GeForce RTX 2080 will be quite a bit (more or less 37%) better at AF than the GeForce RTX 2070. (explain)

GeForce RTX 2080 278760 Mtexels/sec
GeForce RTX 2070 203040 Mtexels/sec
Difference: 75720 (37%)

Pixel Rate

The GeForce RTX 2080 will be just a bit (more or less 7%) better at anti-aliasing than the GeForce RTX 2070, and should be able to handle higher screen resolutions without losing too much performance. (explain)

GeForce RTX 2080 96960 Mpixels/sec
GeForce RTX 2070 90240 Mpixels/sec
Difference: 6720 (7%)

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 transferred over the external memory interface in one second. It's worked out by multiplying the card's interface width by its memory speed. If it uses DDR RAM, the result should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the most pixels the video card can possibly record to the local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the number of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate is also dependant on quite a few other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the max fill rate.
