Nvidia Titan X vs Radeon RX 6800 XT

Intro

The Nvidia Titan X has a core clock frequency of 1417 MHz and a GDDR5X memory frequency of 1251 MHz. It also uses a 384-bit bus, and uses a 16 nm design. It features 3584 SPUs, 224 TAUs, and 96 Raster Operation Units.

Compare that to the Radeon RX 6800 XT, which makes use of a 7 nm design. AMD has set the core speed at 1825 MHz. The GDDR6 memory works at a speed of 2000 MHz on this specific model. It features 4608 SPUs along with 288 TAUs and 128 Rasterization Operator Units.

Specifications

Memory Bandwidth: Memory bandwidth is the largest amount of information (in units of megabytes per second) that can be moved across the external memory interface within a second. The number is calculated by multiplying the bus width by its memory speed. In the case of DDR type memory, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card could possibly write to the local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the number of colour ROPs by the clock 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 fill rate also depends on quite a few other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the max fill rate.
