GeForce RTX 2080 vs Nvidia Titan Xp

Intro

The GeForce RTX 2080 makes use of a 12 nm design. nVidia has set the core speed at 1515 MHz. The GDDR6 RAM runs at a speed of 1750 MHz on this particular model. It features 2944 SPUs as well as 184 Texture Address Units and 64 ROPs.

Compare those specs to the Nvidia Titan Xp, which features core clock speeds of 1582 MHz on the GPU, and 1426 MHz on the 12288 MB of GDDR5X RAM. It features 3840 SPUs along with 240 Texture Address Units and 96 ROPs.

Specifications

Memory Bandwidth: Bandwidth is the maximum amount of data (counted in MB per second) that can be transported past the external memory interface within a second. The number is calculated by multiplying the card's bus width by its memory speed. If it uses DDR type memory, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, 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 can be applied in one second. This is worked out by multiplying the total texture units of the card by the core 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 processed in a second.

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