GeForce RTX 2070 vs GeForce RTX 2080

Intro

Compare all that to the GeForce RTX 2080, which features a GPU core clock speed of 1515 MHz, and 8192 MB of GDDR6 memory running at 1750 MHz through a 256-bit bus. It also is made up of 2944 Stream Processors, 184 TAUs, and 64 Raster Operation Units.

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

Memory Bandwidth

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

Texel Rate

The GeForce RTX 2080 will be quite a bit (more or less 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

If using a high resolution is important to you, then the GeForce RTX 2080 is the winner, but only just. (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 (measured in MB per second) that can be moved across the external memory interface in one second. It's worked out by multiplying the card's bus width by its memory clock speed. In the case of DDR memory, it must be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

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

Pixel Rate: Pixel rate is the most pixels the video card can possibly write to its local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the amount of Raster Operations Pipelines by the clock speed of the card. 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 lots of other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
