GeForce RTX 3080 12 GB vs GeForce RTX 3080 Ti

Intro

The GeForce RTX 3080 12 GB makes use of a 8 nm design. nVidia has clocked the core speed at 1260 MHz. The GDDR6X memory runs at a frequency of 1188 MHz on this specific card. It features 8960 SPUs along with 280 Texture Address Units and 112 Rasterization Operator Units.

Compare those specifications to the GeForce RTX 3080 Ti, which comes with a GPU core clock speed of 1365 MHz, and 12288 MB of GDDR6X memory set to run at 1188 MHz through a 384-bit bus. It also features 10240 SPUs, 320 TAUs, and 112 ROPs.

Specifications

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

Pixel Rate: Pixel rate is the most pixels that the graphics chip could possibly write to the local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - aka 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 of the card - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
