GeForce GTX 1080 vs GeForce RTX 2060

Intro

The GeForce GTX 1080 comes with a clock frequency of 1607 MHz and a GDDR5X memory frequency of 1251 MHz. It also makes use of a 256-bit bus, and uses a 16 nm design. It is made up of 2560 SPUs, 160 Texture Address Units, and 64 ROPs.

Compare those specifications to the GeForce RTX 2060, which has a clock speed of 1365 MHz and a GDDR6 memory speed of 14000 MHz. It also features a 192-bit memory bus, and makes use of a 12 nm design. It features 1920 SPUs, 120 TAUs, and 48 ROPs.

Memory Bandwidth: Memory bandwidth is the largest amount of data (in units of MB per second) that can be transported across the external memory interface in a second. It's worked out by multiplying the card's interface width by its memory clock speed. If the card has DDR type memory, the result should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. 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 number of texture map elements (texels) that can be applied per second. This is calculated by multiplying the total number of texture units by the core clock speed of the chip. The better this number, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card could possibly write to the local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate also depends on quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
