Radeon HD 7950 vs Radeon RX 5600 XT

Intro

Compare that to the Radeon RX 5600 XT, which features a GPU core clock speed of 1375 MHz, and 6144 MB of GDDR6 memory set to run at 1500 MHz through a 192-bit bus. It also is made up of 2304 SPUs, 144 TAUs, and 64 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon RX 5600 XT		160 Watts
Radeon HD 7950		200 Watts
	Difference: 40 Watts (25%)

Memory Bandwidth

Theoretically, the Radeon RX 5600 XT should be quite a bit faster than the Radeon HD 7950 in general. (explain)

Radeon RX 5600 XT		344064 MB/sec
Radeon HD 7950		240000 MB/sec
	Difference: 104064 (43%)

Texel Rate

The Radeon RX 5600 XT will be a lot (approximately 121%) faster with regards to texture filtering than the Radeon HD 7950. (explain)

Radeon RX 5600 XT		198000 Mtexels/sec
Radeon HD 7950		89600 Mtexels/sec
	Difference: 108400 (121%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the Radeon RX 5600 XT is a better choice, by far. (explain)

Radeon RX 5600 XT		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 megabytes per second) that can be transported across the external memory interface in a second. The number is worked out by multiplying the card's bus width by its memory speed. In the case of DDR type RAM, it should be multiplied by 2 once 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 processed per second. This is worked out by multiplying the total texture units by the core speed of the chip. The better this number, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card can possibly record to its local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate is also dependant on lots of other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the max fill rate.
