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 is comprised of 2560 SPUs, 160 TAUs, and 64 ROPs.

Compare all that to the GeForce RTX 3060, which makes use of a 8 nm design. nVidia has clocked the core frequency at 1320 MHz. The GDDR6 memory works at a frequency of 1875 MHz on this card. It features 3584 SPUs along with 112 Texture Address Units and 48 Rasterization Operator Units.

GeForce GTX 1080 327680 MB/sec
Difference: 40960 (13%)

Texel Rate

The GeForce GTX 1080 is quite a bit (more or less 74%) more effective at AF than the GeForce RTX 3060. (explain)

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 full screen anti-aliasing than the GeForce RTX 3060, and should be capable of handling higher resolutions while still performing well. (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: Memory bandwidth is the largest amount of data (counted in megabytes per second) that can be moved across the external memory interface in one second. The number is calculated by multiplying the card's bus width by its memory clock speed. If the card has DDR type memory, it should be multiplied by 2 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 high resolutions.

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

Pixel Rate: Pixel rate is the most pixels that the graphics chip can possibly record to its local memory in a 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 - aka 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 - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
