GeForce RTX 3070 vs GeForce RTX 3080

Intro

Compare all that to the GeForce RTX 3080, which has core speeds of 1440 MHz on the GPU, and 1188 MHz on the 10240 MB of GDDR6X RAM. It features 8704 SPUs as well as 272 Texture Address Units and 96 Rasterization Operator Units.

GeForce RTX 3070		(Unknown) MB/sec
	Difference: 778547 (-100%)

Texel Rate

The GeForce RTX 3080 is a lot (about 42%) more effective at anisotropic filtering than the GeForce RTX 3070. (explain)

GeForce RTX 3080		391680 Mtexels/sec
GeForce RTX 3070		276000 Mtexels/sec
	Difference: 115680 (42%)

Pixel Rate

If running with a high screen resolution is important to you, then the GeForce RTX 3070 is superior to the GeForce RTX 3080, but only just. (explain)

GeForce RTX 3070		144000 Mpixels/sec
GeForce RTX 3080		138240 Mpixels/sec
	Difference: 5760 (4%)

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 (in units of megabytes per second) that can be transported past the external memory interface in a second. It's calculated by multiplying the card's bus width by the speed of its memory. In the case of DDR type RAM, it should be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels the video card could possibly write to its local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the number of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate is also dependant on lots of other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
