GeForce RTX 2070 vs GeForce RTX 2080

Intro

The GeForce RTX 2070 makes use of a 12 nm design. nVidia has clocked the core speed at 1410 MHz. The GDDR6 memory works at a frequency of 14 MHz on this particular card. It features 2304 SPUs along with 144 Texture Address Units and 64 Rasterization Operator Units.

Compare those specs to the GeForce RTX 2080, which features a core clock frequency of 1515 MHz and a GDDR6 memory frequency of 14 MHz. It also features a 256-bit memory bus, and uses a 12 nm design. It is comprised of 2944 SPUs, 184 Texture Address Units, and 64 ROPs.

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 in theory they should perform exactly the same. (explain)

Texel Rate

The GeForce RTX 2080 is a lot (about 37%) faster with regards to anisotropic filtering than the GeForce RTX 2070. (explain)

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

Pixel Rate

If using high levels of AA is important to you, then the GeForce RTX 2080 is the winner, not by a very large margin though. (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: Memory bandwidth is the largest amount of data (counted in megabytes per second) that can be transferred across the external memory interface in one second. The number is calculated by multiplying the card's bus width by its memory speed. If the card has DDR type RAM, it must be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels the video card could possibly write to the local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the number of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on 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 ability to get to the max fill rate.
