GeForce GTX 1080 vs GeForce RTX 3060

Intro

The GeForce GTX 1080 features a GPU clock speed of 1607 MHz, and the 8192 MB of GDDR5X memory runs at 1251 MHz through a 256-bit bus. It also features 2560 SPUs, 160 Texture Address Units, and 64 ROPs.

Compare all that to the GeForce RTX 3060, which comes with GPU core speed of 1320 MHz, and (Unknown) MB of GDDR6 memory set to run at 1875 MHz through a 192-bit bus. It also is comprised of 3584 SPUs, 112 TAUs, and 48 Raster Operation Units.

GeForce GTX 1080 257120 Mtexels/sec
GeForce RTX 3060 147840 Mtexels/sec
Difference: 109280 (74%)

Pixel Rate

The GeForce GTX 1080 is a lot (approximately 62%) better at anti-aliasing than the GeForce RTX 3060, and also capable of handling higher screen resolutions without losing too much performance. (explain)

GeForce GTX 1080 102848 Mpixels/sec
GeForce RTX 3060 63360 Mpixels/sec
Difference: 39488 (62%)

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.

Memory Bandwidth: Bandwidth is the maximum amount of data (in units of MB per second) that can be transported across the external memory interface in a second. The number is worked out by multiplying the interface width by its memory speed. In the case of DDR type memory, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the better 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 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 this number, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second.

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