GeForce RTX 2070 vs GeForce RTX 3080

Intro

Compare those specifications to the GeForce RTX 3080, which features a clock frequency of 1440 MHz and a GDDR6X memory frequency of 1188 MHz. It also features a 320-bit bus, and makes use of a 8 nm design. It is comprised of 8704 SPUs, 272 Texture Address Units, and 96 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce RTX 2070		175 Watts
GeForce RTX 3080		320 Watts
	Difference: 145 Watts (83%)

Memory Bandwidth

Theoretically speaking, the GeForce RTX 3080 should perform quite a bit faster than the GeForce RTX 2070 in general. (explain)

GeForce RTX 3080		778547 MB/sec
GeForce RTX 2070		458752 MB/sec
	Difference: 319795 (70%)

Texel Rate

The GeForce RTX 3080 will be much (about 93%) faster with regards to anisotropic filtering than the GeForce RTX 2070. (explain)

GeForce RTX 3080		391680 Mtexels/sec
GeForce RTX 2070		203040 Mtexels/sec
	Difference: 188640 (93%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the GeForce RTX 3080 is superior to the GeForce RTX 2070, and very much so. (explain)

GeForce RTX 3080		138240 Mpixels/sec
GeForce RTX 2070		90240 Mpixels/sec
	Difference: 48000 (53%)

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 information (counted in megabytes per second) that can be transported across the external memory interface in a second. The number is calculated by multiplying the card's interface width by its memory clock speed. In the case of DDR RAM, it should be multiplied by 2 once again. If it uses 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 worked out 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 handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.

Pixel Rate: Pixel rate is the maximum amount of pixels the video card could possibly record to the local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate also depends on many other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
