Radeon R9 Fury X vs Radeon RX 6800

Intro

The Radeon R9 Fury X comes with a core clock speed of 1050 MHz and a HBM memory speed of 500 MHz. It also features a 4096-bit bus, and makes use of a 28 nm design. It features 4096 SPUs, 256 TAUs, and 64 ROPs.

Compare those specs to the Radeon RX 6800, which uses a 7 nm design. AMD has set the core speed at 1700 MHz. The GDDR6 memory is set to run at a frequency of 2000 MHz on this model. It features 3840 SPUs as well as 240 Texture Address Units and 96 ROPs.

Memory Bandwidth: Bandwidth is the largest amount of information (in units of MB per second) that can be transferred across the external memory interface within a second. It's calculated by multiplying the interface width by the speed of its memory. If the card has DDR type RAM, the result should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the faster 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 amount of texture map elements (texels) that can be processed per second. This figure is calculated by multiplying the total texture units of the card by the core clock speed of the chip. The higher the texel rate, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.

Pixel Rate: Pixel rate is the maximum number of pixels the video card could possibly record to the local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the amount 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 rate also depends on many other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the max fill rate.
