GeForce RTX 2070 Super vs GeForce RTX 2080 SUPER

Intro

Compare those specifications to the GeForce RTX 2080 SUPER, which comes with a clock frequency of 1650 MHz and a GDDR6 memory speed of 1937 MHz. It also makes use of a 256-bit memory bus, and uses a 12 nm design. It is comprised of 3072 SPUs, 192 TAUs, and 64 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce RTX 2070 Super		215 Watts
GeForce RTX 2080 SUPER		250 Watts
	Difference: 35 Watts (16%)

Memory Bandwidth

Theoretically speaking, the GeForce RTX 2080 SUPER will be 11% faster than the GeForce RTX 2070 Super in general, because of its higher data rate. (explain)

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

Texel Rate

The GeForce RTX 2080 SUPER will be much (more or less 23%) more effective at AF than the GeForce RTX 2070 Super. (explain)

GeForce RTX 2080 SUPER		316800 Mtexels/sec
GeForce RTX 2070 Super		256800 Mtexels/sec
	Difference: 60000 (23%)

Pixel Rate

The GeForce RTX 2080 SUPER should be a little bit (about 3%) more effective at full screen anti-aliasing than the GeForce RTX 2070 Super, and also able to handle higher screen resolutions more effectively. (explain)

GeForce RTX 2080 SUPER		105600 Mpixels/sec
GeForce RTX 2070 Super		102720 Mpixels/sec
	Difference: 2880 (3%)

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 information (counted in megabytes per second) that can be transported across the external memory interface within a second. It's calculated by multiplying the card's interface width by the speed of its memory. If it uses DDR type RAM, the result should be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the faster 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 amount of texture map elements (texels) that are processed in one second. This is worked out 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 texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card could possibly record to the local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. 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 max fill rate.
