GeForce RTX 2070 vs GeForce RTX 2080

Intro

Compare that to the GeForce RTX 2080, which has GPU clock speed of 1515 MHz, and 8192 MB of GDDR6 memory running at 1750 MHz through a 256-bit bus. It also is comprised of 2944 Stream Processors, 184 TAUs, 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 have identical performance. (explain)

Texel Rate

The GeForce RTX 2080 will be much (approximately 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 running with high levels of AA is important to you, then the GeForce RTX 2080 is a better choice, though only just barely. (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 largest amount of data (in units of megabytes per second) that can be transferred across the external memory interface within a second. It is worked out by multiplying the interface width by the speed of its memory. If the card has DDR type memory, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the bandwidth is, the better the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be processed per second. This number is worked out by multiplying the total texture units by the core clock speed of the chip. The better the texel rate, the better the graphics 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 could possibly record to its local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate is also dependant on lots of other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
