GeForce RTX 3070 Ti vs GeForce RTX 4080

Intro

The GeForce RTX 3070 Ti comes with a GPU core speed of 1575 MHz, and the 8192 MB of GDDR6X RAM runs at 1188 MHz through a 256-bit bus. It also features 6144 SPUs, 192 TAUs, and 96 ROPs.

Compare that to the GeForce RTX 4080, which has a GPU core clock speed of 2205 MHz, and 16384 MB of GDDR6X memory running at 1400 MHz through a 256-bit bus. It also is comprised of 9728 SPUs, 304 TAUs, and 112 Raster Operation Units.

Memory Bandwidth: Memory bandwidth is the max amount of information (counted in megabytes per second) that can be moved across the external memory interface in one second. It is calculated by multiplying the bus width by the speed of its memory. In the case of DDR RAM, it must be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are applied per 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 in one second.

Pixel Rate: Pixel rate is the maximum amount of pixels the video 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 number of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate is also dependant on lots of other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
