GeForce RTX 2080 SUPER vs GeForce RTX 3070

Intro

Compare those specifications to the GeForce RTX 3070, which has GPU clock speed of 1500 MHz, and 8192 MB of GDDR6 memory running at 1750 MHz through a 256-bit bus. It also is made up of 5888 Stream Processors, 184 TAUs, and 96 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce RTX 3070		220 Watts
GeForce RTX 2080 SUPER		250 Watts
	Difference: 30 Watts (14%)

Memory Bandwidth

In theory, the GeForce RTX 2080 SUPER is -100% quicker than the GeForce RTX 3070 overall, due to its greater bandwidth. (explain)

GeForce RTX 2080 SUPER		507904 MB/sec
GeForce RTX 3070		(Unknown) MB/sec
	Difference: 507904 (-100%)

Texel Rate

The GeForce RTX 2080 SUPER is a small bit (about 15%) more effective at AF than the GeForce RTX 3070. (explain)

GeForce RTX 2080 SUPER		316800 Mtexels/sec
GeForce RTX 3070		276000 Mtexels/sec
	Difference: 40800 (15%)

Pixel Rate

The GeForce RTX 3070 will be quite a bit (more or less 36%) better at anti-aliasing than the GeForce RTX 2080 SUPER, and also should be able to handle higher screen resolutions while still performing well. (explain)

GeForce RTX 3070		144000 Mpixels/sec
GeForce RTX 2080 SUPER		105600 Mpixels/sec
	Difference: 38400 (36%)

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 largest amount of data (counted in megabytes per second) that can be transferred across the external memory interface in a second. The number is calculated by multiplying the card's interface width by its memory clock speed. If the card has DDR type RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the memory bandwidth, the faster 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 can be applied per second. This figure is calculated by multiplying the total number of texture units of the card by the core clock speed of the chip. The higher this number, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card can possibly write to the local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of Raster Operations Pipelines by the the core 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 output rate also depends on many other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
