Nvidia Titan X vs Radeon RX 6800 XT

Intro

The Nvidia Titan X comes with a clock frequency of 1417 MHz and a GDDR5X memory frequency of 1251 MHz. It also uses a 384-bit memory bus, and makes use of a 16 nm design. It features 3584 SPUs, 224 TAUs, and 96 ROPs.

Compare those specifications to the Radeon RX 6800 XT, which has core speeds of 1825 MHz on the GPU, and 2000 MHz on the 16384 MB of GDDR6 RAM. It features 4608 SPUs as well as 288 Texture Address Units and 128 ROPs.

Specifications

Memory Bandwidth: Memory bandwidth is the maximum amount of information (counted in megabytes per second) that can be transported over the external memory interface in one second. It is worked out by multiplying the interface width by the speed of its memory. If it uses DDR type memory, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be processed per second. This number is worked out by multiplying the total number of texture units by the core clock speed of the chip. The better this number, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip can possibly record to its local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill 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 maximum fill rate.
