Radeon HD 7790 vs Radeon RX 5600 XT

Intro

The Radeon HD 7790 makes use of a 28 nm design. AMD has clocked the core speed at 1000 MHz. The GDDR5 RAM runs at a frequency of 1500 MHz on this particular card. It features 896 SPUs along with 56 Texture Address Units and 16 Rasterization Operator Units.

Compare those specs to the Radeon RX 5600 XT, which comes with a clock speed of 1375 MHz and a GDDR6 memory speed of 1500 MHz. It also features a 192-bit bus, and makes use of a 7 nm design. It features 2304 SPUs, 144 TAUs, and 64 ROPs.

Memory Bandwidth: Memory bandwidth is the max amount of information (measured in megabytes per second) that can be moved across the external memory interface within a second. It's calculated by multiplying the interface width by its memory speed. If the card has DDR type RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the bandwidth is, the better the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels the video card can possibly record to the local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate also depends on quite a few other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the max fill rate.
