GeForce RTX 2080 SUPER vs GeForce RTX 3080

Intro

The GeForce RTX 2080 SUPER comes with a core clock speed of 1650 MHz and a GDDR6 memory frequency of 1937 MHz. It also uses a 256-bit bus, and uses a 12 nm design. It features 3072 SPUs, 192 TAUs, and 64 ROPs.

Compare all of that to the GeForce RTX 3080, which has core clock speeds of 1440 MHz on the GPU, and 1188 MHz on the 10240 MB of GDDR6X RAM. It features 8704 SPUs along with 272 TAUs and 96 ROPs.

Memory Bandwidth: Memory bandwidth is the maximum amount of data (counted in megabytes per second) that can be transported over the external memory interface in one second. It's worked out by multiplying the card's interface width by its memory clock speed. In the case of DDR memory, it must be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

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

Pixel Rate: Pixel rate is the most pixels the graphics card can possibly write to its local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate also depends on lots of other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
