Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon HD 4850 512MB		110 Watts
Radeon RX 5600 XT		160 Watts
	Difference: 50 Watts (45%)

Memory Bandwidth

Theoretically speaking, the Radeon RX 5600 XT is 441% quicker than the Radeon HD 4850 512MB in general, due to its greater data rate. (explain)

Radeon RX 5600 XT		344064 MB/sec
Radeon HD 4850 512MB		63552 MB/sec
	Difference: 280512 (441%)

Texel Rate

The Radeon RX 5600 XT will be quite a bit (more or less 692%) more effective at AF than the Radeon HD 4850 512MB. (explain)

Radeon RX 5600 XT		198000 Mtexels/sec
Radeon HD 4850 512MB		25000 Mtexels/sec
	Difference: 173000 (692%)

Pixel Rate

The Radeon RX 5600 XT will be a lot (approximately 780%) more effective at full screen anti-aliasing than the Radeon HD 4850 512MB, and will be able to handle higher screen resolutions without losing too much performance. (explain)

Radeon RX 5600 XT		88000 Mpixels/sec
Radeon HD 4850 512MB		10000 Mpixels/sec
	Difference: 78000 (780%)

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 data (in units of megabytes per second) that can be transported across the external memory interface in one second. It is calculated by multiplying the bus width by its memory speed. If the card has DDR type RAM, it should be multiplied by 2 once 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 AA, HDR and high resolutions.

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

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