GeForce RTX 2060 Super vs GeForce RTX 2080 SUPER

Intro

Compare all that to the GeForce RTX 2080 SUPER, which has a clock frequency of 1650 MHz and a GDDR6 memory frequency of 1937 MHz. It also uses a 256-bit memory bus, and makes use of a 12 nm design. It is comprised of 3072 SPUs, 192 Texture Address Units, and 64 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce RTX 2060 Super		175 Watts
GeForce RTX 2080 SUPER		250 Watts
	Difference: 75 Watts (43%)

Memory Bandwidth

Theoretically speaking, the GeForce RTX 2080 SUPER should perform a little bit faster than the GeForce RTX 2060 Super in general. (explain)

GeForce RTX 2080 SUPER		507904 MB/sec
GeForce RTX 2060 Super		458752 MB/sec
	Difference: 49152 (11%)

Texel Rate

The GeForce RTX 2080 SUPER should be quite a bit (more or less 58%) more effective at AF than the GeForce RTX 2060 Super. (explain)

GeForce RTX 2080 SUPER		316800 Mtexels/sec
GeForce RTX 2060 Super		199920 Mtexels/sec
	Difference: 116880 (58%)

Pixel Rate

The GeForce RTX 2080 SUPER is just a bit (more or less 12%) more effective at anti-aliasing than the GeForce RTX 2060 Super, and also should be capable of handling higher resolutions while still performing well. (explain)

GeForce RTX 2080 SUPER		105600 Mpixels/sec
GeForce RTX 2060 Super		94080 Mpixels/sec
	Difference: 11520 (12%)

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 maximum amount of information (in units of megabytes per second) that can be moved past the external memory interface in one second. It's calculated by multiplying the bus width by the speed of its memory. If it uses DDR type memory, it must be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed in one second. This figure 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 card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card can possibly write to the local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the number of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate also depends on lots of other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
