GeForce RTX 2080 vs GeForce RTX 2080 Ti

Intro

The GeForce RTX 2080 makes use of a 12 nm design. nVidia has set the core speed at 1515 MHz. The GDDR6 memory is set to run at a speed of 14 MHz on this particular model. It features 2944 SPUs as well as 184 TAUs and 64 ROPs.

Compare those specs to the GeForce RTX 2080 Ti, which has a clock speed of 1350 MHz and a GDDR6 memory speed of 14 MHz. It also uses a 352-bit memory bus, and makes use of a 12 nm design. It is comprised of 4352 SPUs, 272 TAUs, and 88 Raster Operation Units.

Memory Bandwidth: Bandwidth is the largest amount of information (measured in megabytes per second) that can be transferred across the external memory interface in one second. It is worked out by multiplying the card's interface width by its memory clock speed. If it uses DDR memory, it should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the bandwidth is, 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 can be applied in one second. This number is calculated by multiplying the total number of texture units by the core speed of the chip. The higher the texel rate, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card could possibly record to the local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate also depends on many other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
