Radeon HD 7790 vs Radeon R9 Fury X

Intro

The Radeon HD 7790 makes use of a 28 nm design. AMD has clocked the core speed at 1000 MHz. The GDDR5 memory works at a frequency of 1500 MHz on this specific card. It features 896 SPUs as well as 56 TAUs and 16 Rasterization Operator Units.

Compare all that to the Radeon R9 Fury X, which features core clock speeds of 1050 MHz on the GPU, and 500 MHz on the 4096 MB of HBM memory. It features 4096 SPUs along with 256 Texture Address Units and 64 ROPs.

Memory Bandwidth: Memory bandwidth is the largest amount of data (measured in megabytes per second) that can be transferred past the external memory interface within a second. It's worked out by multiplying the card's interface width by its memory speed. In the case of DDR memory, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the better 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 texture map elements (texels) that can be applied in one second. This figure is worked out by multiplying the total number of texture units by the core clock speed of the chip. The higher this number, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip can possibly record to its local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate also depends on lots of other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
