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 Texture Address Units, and 64 ROPs.

Compare those specs to the GeForce RTX 3060, which features a core clock speed of 1320 MHz and a GDDR6 memory speed of 1875 MHz. It also uses a 192-bit bus, and uses a 8 nm design. It features 3584 SPUs, 112 TAUs, and 48 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce RTX 3060 170 Watts
GeForce GTX 1080 180 Watts
Difference: 10 Watts (6%)

Memory Bandwidth

The GeForce RTX 3060 should theoretically perform just a bit faster than the GeForce GTX 1080 in general. (explain)

GeForce RTX 3060 368640 MB/sec
GeForce GTX 1080 327680 MB/sec
Difference: 40960 (13%)

Texel Rate

The GeForce GTX 1080 should be quite a bit (about 74%) faster with regards to AF than the GeForce RTX 3060. (explain)

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

Pixel Rate

If using a high resolution is important to you, then the GeForce GTX 1080 is a better choice, and very much so. (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 (in units of MB per second) that can be transferred across the external memory interface in a second. The number is worked out by multiplying the card's interface width by its memory speed. If it uses DDR memory, the result should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the card's 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 amount of texture map elements (texels) that are applied in one second. This figure is calculated by multiplying the total texture units of the card by the core clock speed of the chip. The better the texel rate, 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 that the graphics chip could possibly write to the local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the number of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate is also dependant on lots of other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
