Nvidia Titan Xp vs Radeon RX 6800

Intro

The Nvidia Titan Xp makes use of a 16 nm design. nVidia has clocked the core frequency at 1582 MHz. The GDDR5X memory is set to run at a frequency of 1426 MHz on this card. It features 3840 SPUs as well as 240 Texture Address Units and 96 Rasterization Operator Units.

Compare those specifications to the Radeon RX 6800, which uses a 7 nm design. AMD has clocked the core frequency at 1700 MHz. The GDDR6 RAM runs at a frequency of 2000 MHz on this specific card. It features 3840 SPUs along with 240 Texture Address Units and 96 Rasterization Operator Units.

Specifications

Memory Bandwidth: Memory bandwidth is the largest amount of information (measured in megabytes per second) that can be moved across the external memory interface in one second. It's worked out by multiplying the interface width by its memory clock speed. If it uses DDR memory, it must 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 AA, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card can possibly record to the local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate also depends on many other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the max fill rate.
