Radeon RX 480 vs Radeon RX 5700 XT 50th Anniversary Edition

Intro

Compare those specs to the Radeon RX 5700 XT 50th Anniversary Edition, which makes use of a 7 nm design. AMD has clocked the core speed at 1680 MHz. The GDDR6 memory is set to run at a speed of 1750 MHz on this particular card. It features 2560 SPUs along with 160 Texture Address Units and 64 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon RX 480		150 Watts
Radeon RX 5700 XT 50th Anniversary Edition		235 Watts
	Difference: 85 Watts (57%)

Memory Bandwidth

In theory, the Radeon RX 5700 XT 50th Anniversary Edition is 75% quicker than the Radeon RX 480 in general, due to its higher bandwidth. (explain)

Radeon RX 5700 XT 50th Anniversary Edition		458752 MB/sec
Radeon RX 480		262144 MB/sec
	Difference: 196608 (75%)

Texel Rate

The Radeon RX 5700 XT 50th Anniversary Edition should be quite a bit (approximately 67%) more effective at anisotropic filtering than the Radeon RX 480. (explain)

Radeon RX 5700 XT 50th Anniversary Edition		268800 Mtexels/sec
Radeon RX 480		161280 Mtexels/sec
	Difference: 107520 (67%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the Radeon RX 5700 XT 50th Anniversary Edition is the winner, and very much so. (explain)

Radeon RX 5700 XT 50th Anniversary Edition		107520 Mpixels/sec
Radeon RX 480		35840 Mpixels/sec
	Difference: 71680 (200%)

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 largest amount of data (in units of megabytes per second) that can be transported past the external memory interface in one second. It is worked out by multiplying the bus width by its memory speed. In the case of DDR type memory, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be processed in one second. This number is calculated by multiplying the total texture units by the core speed of the chip. The higher this number, the better the card will be at 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 its local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the amount of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to 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 get to the max fill rate.
