GeForce RTX 2070 vs GeForce RTX 2080 SUPER

Intro

Compare all that to the GeForce RTX 2080 SUPER, which uses a 12 nm design. nVidia has clocked the core frequency at 1650 MHz. The GDDR6 memory works at a speed of 1937 MHz on this model. It features 3072 SPUs along with 192 Texture Address Units 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 is 11% faster than the GeForce RTX 2070 in general, due to its greater 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 should be much (more or less 56%) faster with regards to AF than the GeForce RTX 2070. (explain)

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

Pixel Rate

The GeForce RTX 2080 SUPER will be just a bit (about 17%) more effective at AA than the GeForce RTX 2070, and will be capable of handling higher screen resolutions more effectively. (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 max amount of data (counted in MB per second) that can be moved past the external memory interface in one second. It is worked out by multiplying the interface width by the speed of its memory. If it uses DDR type RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are applied in one second. This is worked out by multiplying the total texture units by the core 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 applied in a second.

Pixel Rate: Pixel rate is the most pixels the video card could possibly write to its local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called 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 of the card - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
