Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon HD 7850		130 Watts
Radeon RX 5500		150 Watts
	Difference: 20 Watts (15%)

Memory Bandwidth

The Radeon RX 5500 should in theory be quite a bit faster than the Radeon HD 7850 overall. (explain)

Radeon RX 5500		229376 MB/sec
Radeon HD 7850		153600 MB/sec
	Difference: 75776 (49%)

Texel Rate

The Radeon RX 5500 will be much (more or less 167%) faster with regards to texture filtering than the Radeon HD 7850. (explain)

Radeon RX 5500		146960 Mtexels/sec
Radeon HD 7850		55040 Mtexels/sec
	Difference: 91920 (167%)

Pixel Rate

The Radeon RX 5500 is much (more or less 94%) better at full screen anti-aliasing than the Radeon HD 7850, and should be able to handle higher screen resolutions without losing too much performance. (explain)

Radeon RX 5500		53440 Mpixels/sec
Radeon HD 7850		27520 Mpixels/sec
	Difference: 25920 (94%)

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 largest amount of information (counted in megabytes per second) that can be moved across the external memory interface within a second. It is calculated by multiplying the interface width by its memory clock speed. In the case of DDR type memory, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are applied in one second. This is calculated by multiplying the total texture units of the card 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 one second.

Pixel Rate: Pixel rate is the maximum number of pixels the video card can possibly write to the local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the amount of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate also depends on lots of other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
