Radeon RX 480 vs Radeon RX 5700

Intro

Compare those specs to the Radeon RX 5700, which uses a 7 nm design. AMD has set the core speed at 1465 MHz. The GDDR6 memory works at a frequency of 1750 MHz on this model. It features 2304 SPUs along with 144 Texture Address Units and 64 Rasterization Operator Units.

Radeon RX 480		161280 Mtexels/sec
	Difference: 49680 (31%)

Pixel Rate

The Radeon RX 5700 will be quite a bit (more or less 162%) faster with regards to anti-aliasing than the Radeon RX 480, and should be capable of handling higher resolutions while still performing well. (explain)

Radeon RX 5700		93760 Mpixels/sec
Radeon RX 480		35840 Mpixels/sec
	Difference: 57920 (162%)

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 information (in units of megabytes per second) that can be transported past the external memory interface in a second. The number is calculated by multiplying the card's interface width by its memory speed. If it uses DDR memory, the result should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be 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 video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second.

Pixel Rate: Pixel rate is the maximum amount of pixels the video card can possibly record to its local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of colour 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 output rate also depends on lots of other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
