GeForce RTX 2080 SUPER vs GeForce RTX 4070 Ti

Intro

Compare those specifications to the GeForce RTX 4070 Ti, which has GPU clock speed of 2310 MHz, and 12288 MB of GDDR6X RAM set to run at 1313 MHz through a 192-bit bus. It also is comprised of 7680 Stream Processors, 240 Texture Address Units, and 80 Raster Operation Units.

GeForce RTX 4070 Ti		554400 Mtexels/sec
GeForce RTX 2080 SUPER		316800 Mtexels/sec
	Difference: 237600 (75%)

Pixel Rate

The GeForce RTX 4070 Ti should be quite a bit (more or less 75%) more effective at AA than the GeForce RTX 2080 SUPER, and also should be able to handle higher resolutions without losing too much performance. (explain)

GeForce RTX 4070 Ti		184800 Mpixels/sec
GeForce RTX 2080 SUPER		105600 Mpixels/sec
	Difference: 79200 (75%)

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 information (counted in megabytes per second) that can be transported across the external memory interface in one second. It's worked out by multiplying the card's interface width by its memory clock speed. If it uses DDR RAM, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the bandwidth is, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are applied in one second. This number is calculated by multiplying the total number of texture units 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 chip could possibly write to the local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the amount of colour ROPs 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 output rate also depends 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 max fill rate.
