Radeon HD 7950 vs Radeon RX 5500 XT

Intro

Compare those specifications to the Radeon RX 5500 XT, which features a clock frequency of 1717 MHz and a GDDR6 memory frequency of 1750 MHz. It also makes use of a 128-bit memory bus, and uses a 7 nm design. It is comprised of 1408 SPUs, 88 Texture Address Units, and 32 ROPs.

Radeon RX 5500 XT		130 Watts
Radeon HD 7950		200 Watts
	Difference: 70 Watts (54%)

Memory Bandwidth

Theoretically speaking, the Radeon HD 7950 should perform just a bit faster than the Radeon RX 5500 XT in general. (explain)

Radeon HD 7950		240000 MB/sec
Radeon RX 5500 XT		229376 MB/sec
	Difference: 10624 (5%)

Texel Rate

The Radeon RX 5500 XT is much (more or less 69%) more effective at AF than the Radeon HD 7950. (explain)

Radeon RX 5500 XT		151096 Mtexels/sec
Radeon HD 7950		89600 Mtexels/sec
	Difference: 61496 (69%)

Pixel Rate

If running with a high resolution is important to you, then the Radeon RX 5500 XT is a better choice, and very much so. (explain)

Radeon RX 5500 XT		54944 Mpixels/sec
Radeon HD 7950		25600 Mpixels/sec
	Difference: 29344 (115%)

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 max amount of information (in units of MB per second) that can be moved over the external memory interface in one second. It is calculated by multiplying the card's bus width by its memory speed. In the case of DDR RAM, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the better 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 applied in one second. This number is calculated by multiplying the total texture units by the core clock speed of the chip. The higher the texel rate, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second.

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