GeForce RTX 2070 vs GeForce RTX 2080 SUPER

Intro

Compare those specifications to the GeForce RTX 2080 SUPER, which uses a 12 nm design. nVidia has set the core frequency at 1650 MHz. The GDDR6 RAM runs at a frequency of 1937 MHz on this specific model. It features 3072 SPUs as well as 192 TAUs and 64 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce RTX 2070		175 Watts
GeForce RTX 2080 SUPER		250 Watts
	Difference: 75 Watts (43%)

Memory Bandwidth

In theory, the GeForce RTX 2080 SUPER will be 11% quicker than the GeForce RTX 2070 in general, due to its higher bandwidth. (explain)

GeForce RTX 2080 SUPER		507904 MB/sec
GeForce RTX 2070		458752 MB/sec
	Difference: 49152 (11%)

Texel Rate

The GeForce RTX 2080 SUPER will be much (more or less 56%) more effective at texture filtering than the GeForce RTX 2070. (explain)

GeForce RTX 2080 SUPER		316800 Mtexels/sec
GeForce RTX 2070		203040 Mtexels/sec
	Difference: 113760 (56%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the GeForce RTX 2080 SUPER is the winner, but it probably won't make a huge difference. (explain)

GeForce RTX 2080 SUPER		105600 Mpixels/sec
GeForce RTX 2070		90240 Mpixels/sec
	Difference: 15360 (17%)

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: Memory bandwidth is the largest amount of data (measured in megabytes per second) that can be transported past the external memory interface in one second. It's calculated by multiplying the card's interface width by its memory clock speed. If it uses DDR type RAM, the result should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be applied in one second. This is calculated by multiplying the total amount of texture units by the core clock 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 in a second.

Pixel Rate: Pixel rate is the most pixels the graphics card can possibly record to its local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the number of ROPs 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 output rate is also dependant on quite a few other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
