Radeon HD 7950 vs Radeon RX 5600

Intro

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

Radeon HD 7950		240000 MB/sec
	Difference: 54912 (23%)

Texel Rate

The Radeon RX 5600 will be quite a bit (about 96%) better at texture filtering than the Radeon HD 7950. (explain)

Radeon RX 5600		176000 Mtexels/sec
Radeon HD 7950		89600 Mtexels/sec
	Difference: 86400 (96%)

Pixel Rate

If running with a high screen resolution is important to you, then the Radeon RX 5600 is a better choice, and very much so. (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 data (counted in MB per second) that can be transferred past the external memory interface in one second. The number is worked out by multiplying the interface width by its memory speed. If the card has DDR memory, the result should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be processed per second. This number is worked out by multiplying the total number of texture units by the core speed of the chip. The better the texel rate, the better the 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 most pixels the graphics card can possibly write to the local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of Raster Operations Pipelines 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 rate is also dependant on lots of other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
