Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon RX 5500 XT		130 Watts
Radeon HD 7950 3GB		200 Watts
	Difference: 70 Watts (54%)

Memory Bandwidth

In theory, the Radeon HD 7950 3GB will be 5% faster than the Radeon RX 5500 XT in general, because of its higher data rate. (explain)

Radeon HD 7950 3GB		240000 MB/sec
Radeon RX 5500 XT		229376 MB/sec
	Difference: 10624 (5%)

Texel Rate

The Radeon RX 5500 XT should be much (about 69%) faster with regards to texture filtering than the Radeon HD 7950 3GB. (explain)

Radeon RX 5500 XT		151096 Mtexels/sec
Radeon HD 7950 3GB		89600 Mtexels/sec
	Difference: 61496 (69%)

Pixel Rate

The Radeon RX 5500 XT will be a lot (more or less 115%) better at AA than the Radeon HD 7950 3GB, and also should be capable of handling higher screen resolutions while still performing well. (explain)

Radeon RX 5500 XT		54944 Mpixels/sec
Radeon HD 7950 3GB		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: Memory bandwidth is the max amount of data (counted in megabytes per second) that can be transported past the external memory interface in a second. It's worked out by multiplying the bus width by its memory clock speed. If the card has DDR RAM, it should be multiplied by 2 once again. If it uses 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, HDR and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be processed per second. This is calculated by multiplying the total texture units of the card by the core speed of the chip. The higher 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 number of pixels that the graphics card can possibly write to its local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the number of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate also depends on lots of other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
