Radeon HD 4850 2GB vs Radeon RX 5600 XT

Intro

Compare that to the Radeon RX 5600 XT, which features GPU clock speed of 1375 MHz, and 6144 MB of GDDR6 memory running at 1500 MHz through a 192-bit bus. It also is made up of 2304 Stream Processors, 144 TAUs, and 64 ROPs.

Radeon HD 4850 2GB		63552 MB/sec
	Difference: 280512 (441%)

Texel Rate

The Radeon RX 5600 XT should be a lot (about 692%) more effective at AF than the Radeon HD 4850 2GB. (explain)

Radeon RX 5600 XT		198000 Mtexels/sec
Radeon HD 4850 2GB		25000 Mtexels/sec
	Difference: 173000 (692%)

Pixel Rate

The Radeon RX 5600 XT should be much (more or less 780%) better at AA than the Radeon HD 4850 2GB, and capable of handling higher resolutions without losing too much performance. (explain)

Radeon RX 5600 XT		88000 Mpixels/sec
Radeon HD 4850 2GB		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: Memory bandwidth is the maximum amount of data (in units of MB per second) that can be transferred across the external memory interface within a second. It is worked out by multiplying the interface width by its memory clock speed. In the case of DDR type RAM, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the bandwidth is, 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 texture map elements (texels) that can be applied in one second. This figure is calculated by multiplying the total number of texture units by the core clock speed of the chip. The better the texel rate, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second.

Pixel Rate: Pixel rate is the maximum number of pixels the video card can possibly write to its local memory in a second - measured in millions of pixels per second. Pixel rate is worked out 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 outputting the pixels (image) to the screen. The actual pixel fill rate is also dependant on quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
