Radeon RX 5600 XT		344064 MB/sec
Radeon HD 4830 1GB		57600 MB/sec
	Difference: 286464 (497%)

Texel Rate

The Radeon RX 5600 XT should be a lot (about 976%) better at texture filtering than the Radeon HD 4830 1GB. (explain)

Radeon RX 5600 XT		198000 Mtexels/sec
Radeon HD 4830 1GB		18400 Mtexels/sec
	Difference: 179600 (976%)

Pixel Rate

The Radeon RX 5600 XT should be much (about 857%) faster with regards to FSAA than the Radeon HD 4830 1GB, and will be capable of handling higher screen resolutions better. (explain)

Radeon RX 5600 XT		88000 Mpixels/sec
Radeon HD 4830 1GB		9200 Mpixels/sec
	Difference: 78800 (857%)

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 (counted in megabytes per second) that can be transported across the external memory interface in one second. It's worked out by multiplying the interface width by its memory clock speed. If it uses DDR memory, it should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the faster the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card could possibly record to the local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the amount of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate is also dependant on many other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
