Radeon HD 7950 vs Radeon RX 5600 XT

Intro

Compare those specifications to the Radeon RX 5600 XT, which has GPU clock speed of 1375 MHz, and 6144 MB of GDDR6 RAM running at 1500 MHz through a 192-bit bus. It also is made up of 2304 Stream Processors, 144 TAUs, and 64 Raster Operation Units.

Radeon HD 7950		240000 MB/sec
	Difference: 104064 (43%)

Texel Rate

The Radeon RX 5600 XT is much (about 121%) more effective at anisotropic 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

The Radeon RX 5600 XT will be quite a bit (approximately 244%) better at AA than the Radeon HD 7950, and should be able to handle higher resolutions without losing too much performance. (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: Memory bandwidth is the max amount of data (in units of megabytes per second) that can be moved over the external memory interface within a second. The number is worked out by multiplying the bus width by its memory clock speed. In the case of DDR RAM, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the most pixels that the graphics card could possibly record to the local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate is also dependant on quite a few other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the max fill rate.
