Radeon RX 480 4GB vs Radeon RX 5700 XT

Intro

Compare those specifications to the Radeon RX 5700 XT, which has a clock frequency of 1605 MHz and a GDDR6 memory speed of 1750 MHz. It also features a 256-bit memory bus, and makes use of a 7 nm design. It is comprised of 2560 SPUs, 160 Texture Address Units, and 64 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon RX 480 4GB		150 Watts
Radeon RX 5700 XT		225 Watts
	Difference: 75 Watts (50%)

Memory Bandwidth

Theoretically speaking, the Radeon RX 5700 XT should be 100% faster than the Radeon RX 480 4GB overall, because of its greater data rate. (explain)

Radeon RX 5700 XT		458752 MB/sec
Radeon RX 480 4GB		229376 MB/sec
	Difference: 229376 (100%)

Texel Rate

The Radeon RX 5700 XT should be a lot (more or less 59%) more effective at anisotropic filtering than the Radeon RX 480 4GB. (explain)

Radeon RX 5700 XT		256800 Mtexels/sec
Radeon RX 480 4GB		161280 Mtexels/sec
	Difference: 95520 (59%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the Radeon RX 5700 XT is superior to the Radeon RX 480 4GB, by a large margin. (explain)

Radeon RX 5700 XT		102720 Mpixels/sec
Radeon RX 480 4GB		35840 Mpixels/sec
	Difference: 66880 (187%)

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 maximum amount of information (in units of megabytes per second) that can be transported over the external memory interface in one second. It's calculated by multiplying the bus width by the speed of its memory. If the card has DDR memory, it must be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are processed in one second. This figure 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 applied in one second.

Pixel Rate: Pixel rate is the most pixels the graphics card can possibly write to the local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the amount of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate also depends on lots of other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the max fill rate.
