Radeon RX 480 4GB vs Radeon RX 6800

Intro

Compare those specifications to the Radeon RX 6800, which features a GPU core clock speed of 1700 MHz, and 16384 MB of GDDR6 RAM set to run at 2000 MHz through a 256-bit bus. It also is comprised of 3840 Stream Processors, 240 Texture Address Units, and 96 ROPs.

Radeon RX 480 4GB		229376 MB/sec
	Difference: 294912 (129%)

Texel Rate

The Radeon RX 6800 is much (approximately 153%) more effective at texture filtering than the Radeon RX 480 4GB. (explain)

Radeon RX 6800		408000 Mtexels/sec
Radeon RX 480 4GB		161280 Mtexels/sec
	Difference: 246720 (153%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the Radeon RX 6800 is a better choice, by a large margin. (explain)

Radeon RX 6800		163200 Mpixels/sec
Radeon RX 480 4GB		35840 Mpixels/sec
	Difference: 127360 (355%)

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 largest amount of information (in units of MB per second) that can be transferred past the external memory interface in a second. The number is calculated by multiplying the bus width by its memory speed. In the case of DDR type memory, it must be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the bandwidth is, the faster the card will be in general. It especially helps with AA, HDR and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied per second. This is worked out by multiplying the total texture units of the card 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 applied in one second.

Pixel Rate: Pixel rate is the most pixels that the graphics card could possibly write to its local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of Render Output Units by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate is also dependant on quite a few other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
