Radeon HD 4830 512MB vs Radeon RX 5600 XT

Intro

Compare all that to the Radeon RX 5600 XT, which uses a 7 nm design. AMD has set the core speed at 1375 MHz. The GDDR6 RAM works at a frequency of 1500 MHz on this specific model. It features 2304 SPUs as well as 144 Texture Address Units and 64 Rasterization Operator Units.

Pixel Rate

The Radeon RX 5600 XT will be a lot (more or less 857%) more effective at FSAA than the Radeon HD 4830 512MB, and should be able to handle higher resolutions without slowing down too much. (explain)

Radeon RX 5600 XT		88000 Mpixels/sec
Radeon HD 4830 512MB		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 maximum amount of data (measured in MB per second) that can be transported across the external memory interface within a second. It is worked out by multiplying the bus width by its memory clock speed. In the case of DDR memory, it must be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

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

Pixel Rate: Pixel rate is the most pixels the video 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 amount of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate also depends on quite a few other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
