Radeon HD 7950 vs Radeon RX 5600

Intro

Compare all of that to the Radeon RX 5600, which features GPU core speed of 1375 MHz, and 6144 MB of GDDR6 memory running at 1500 MHz through a 192-bit bus. It also is made up of 2048 Stream Processors, 128 Texture Address Units, and 64 ROPs.

Radeon HD 7950		89600 Mtexels/sec
	Difference: 86400 (96%)

Pixel Rate

If running with high levels of AA is important to you, then the Radeon RX 5600 is a better choice, by far. (explain)

Radeon RX 5600		88000 Mpixels/sec
Radeon HD 7950		25600 Mpixels/sec
	Difference: 62400 (244%)

Please note that the above 'benchmarks' are all just theoretical - the results were calculated based on the card's specifications, and real-world performance may (and probably will) vary at least a bit.

Specifications

Memory Bandwidth: Bandwidth is the largest amount of information (in units of MB per second) that can be transferred past the external memory interface in a second. The number is calculated by multiplying the interface width by its memory clock speed. If the card has DDR type RAM, the result should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and high resolutions.

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

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