GeForce RTX 2070 vs GeForce RTX 2080

Intro

Compare those specs to the GeForce RTX 2080, which has core clock speeds of 1515 MHz on the GPU, and 1750 MHz on the 8192 MB of GDDR6 memory. It features 2944 SPUs along with 184 Texture Address Units and 64 Rasterization Operator Units.

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 a lot (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

If running with a high screen resolution is important to you, then the GeForce RTX 2080 is a better choice, but it probably won't make a huge difference. (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 maximum amount of data (measured in MB per second) that can be moved past the external memory interface in a second. The number is calculated by multiplying the card's bus width by its memory clock speed. In the case of DDR type memory, it must be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

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

Pixel Rate: Pixel rate is the most pixels that the graphics card could possibly record to its local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - aka 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 - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
