GeForce RTX 3080 vs GeForce RTX 3080 Ti

Intro

The GeForce RTX 3080 has core clock speeds of 1440 MHz on the GPU, and 1188 MHz on the 10240 MB of GDDR6X RAM. It features 8704 SPUs as well as 272 TAUs and 96 Rasterization Operator Units.

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

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

Pixel Rate: Pixel rate is the maximum amount of pixels the video card can possibly write to the local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of Raster Operations Pipelines 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 fill rate also depends on quite a few other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
