GeForce RTX 2070 vs GeForce RTX 2080

Intro

Compare that to the GeForce RTX 2080, which has a GPU core clock speed of 1515 MHz, and 8192 MB of GDDR6 RAM set to run at 1750 MHz through a 256-bit bus. It also is comprised of 2944 Stream Processors, 184 Texture Address Units, and 64 ROPs.

3DMark Fire Strike Graphics Score

GeForce RTX 2080		26155 points
GeForce RTX 2070		22282 points
	Difference: 3873 (17%)

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 memory bandwidth, so in theory they should perform exactly the same. (explain)

Texel Rate

The GeForce RTX 2080 will be quite a bit (about 37%) more effective 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 should be just a bit (approximately 7%) faster with regards to FSAA than the GeForce RTX 2070, and also should be capable of handling higher screen resolutions while still performing well. (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.

Specifications

Memory Bandwidth: Bandwidth is the max amount of data (counted in MB per second) that can be moved past the external memory interface in one second. It's worked out by multiplying the card's bus width by its memory clock speed. If it uses DDR type 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 number of texture map elements (texels) that can be processed per second. This number is calculated by multiplying the total number of texture units of the card by the core clock speed of the chip. The higher this number, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second.

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card can possibly write to its local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the amount of colour 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 quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
