GeForce GTX 550 Ti 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 RAM runs at a speed of 1937 MHz on this specific model. It features 3072 SPUs along with 192 Texture Address Units and 64 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GTX 550 Ti		116 Watts
GeForce RTX 2080 SUPER		250 Watts
	Difference: 134 Watts (116%)

Memory Bandwidth

Theoretically speaking, the GeForce RTX 2080 SUPER should perform a lot faster than the GeForce GTX 550 Ti in general. (explain)

GeForce RTX 2080 SUPER		507904 MB/sec
GeForce GTX 550 Ti		98496 MB/sec
	Difference: 409408 (416%)

Texel Rate

The GeForce RTX 2080 SUPER will be much (about 1000%) more effective at anisotropic filtering than the GeForce GTX 550 Ti. (explain)

GeForce RTX 2080 SUPER		316800 Mtexels/sec
GeForce GTX 550 Ti		28800 Mtexels/sec
	Difference: 288000 (1000%)

Pixel Rate

The GeForce RTX 2080 SUPER should be quite a bit (more or less 389%) faster with regards to AA than the GeForce GTX 550 Ti, and also should be able to handle higher screen resolutions without losing too much performance. (explain)

GeForce RTX 2080 SUPER		105600 Mpixels/sec
GeForce GTX 550 Ti		21600 Mpixels/sec
	Difference: 84000 (389%)

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 max amount of data (measured in megabytes per second) that can be moved across the external memory interface in one second. It's worked out by multiplying the bus width by the speed of its memory. If it uses DDR type RAM, the result should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip 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 number of colour ROPs by the the core speed of the card. 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 output rate is also dependant on quite a few other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
