GeForce RTX 3070 vs GeForce RTX 3080

Intro

The GeForce RTX 3070 features a core clock speed of 1500 MHz and a GDDR6 memory speed of 1750 MHz. It also uses a 256-bit memory bus, and makes use of a 8 nm design. It is made up of 5888 SPUs, 184 TAUs, and 96 Raster Operation Units.

Compare those specifications to the GeForce RTX 3080, which comes with GPU clock speed of 1440 MHz, and 10240 MB of GDDR6X memory running at 1188 MHz through a 320-bit bus. It also is made up of 8704 SPUs, 272 TAUs, and 96 ROPs.

Memory Bandwidth: Bandwidth is the largest amount of information (measured in MB per second) that can be transported past the external memory interface within a second. The number is worked out by multiplying the bus width by its memory speed. In the case of DDR type memory, it must be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the better the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are applied in one second. This number is worked out 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 texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second.

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card could possibly record to its local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate also depends on lots of other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
