Radeon RX 470 4GB vs Radeon RX 5500

Intro

Compare all that to the Radeon RX 5500, which has a GPU core clock speed of 1670 MHz, and 4096 MB of GDDR6 RAM set to run at 1750 MHz through a 128-bit bus. It also is comprised of 1408 SPUs, 88 Texture Address Units, and 32 Raster Operation Units.

Radeon RX 470 4GB		120 Watts
Radeon RX 5500		150 Watts
	Difference: 30 Watts (25%)

Memory Bandwidth

Theoretically speaking, the Radeon RX 5500 is 9% quicker than the Radeon RX 470 4GB overall, due to its greater data rate. (explain)

Radeon RX 5500		229376 MB/sec
Radeon RX 470 4GB		211200 MB/sec
	Difference: 18176 (9%)

Texel Rate

The Radeon RX 5500 should be quite a bit (about 24%) better at AF than the Radeon RX 470 4GB. (explain)

Radeon RX 5500		146960 Mtexels/sec
Radeon RX 470 4GB		118528 Mtexels/sec
	Difference: 28432 (24%)

Pixel Rate

The Radeon RX 5500 should be a lot (more or less 80%) better at anti-aliasing than the Radeon RX 470 4GB, and able to handle higher screen resolutions more effectively. (explain)

Radeon RX 5500		53440 Mpixels/sec
Radeon RX 470 4GB		29632 Mpixels/sec
	Difference: 23808 (80%)

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 (counted in MB per second) that can be transferred over the external memory interface in one second. It is calculated by multiplying the card's bus width by its memory clock speed. If the card has DDR memory, it must be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the faster 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 number of texture map elements (texels) that are processed per second. This number is calculated by multiplying the total number of texture units of the card by the core speed of the chip. The better 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 a second.

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