Radeon RX 470 4GB vs Radeon RX 5500

Intro

Compare that to the Radeon RX 5500, which features core clock speeds of 1670 MHz on the GPU, and 1750 MHz on the 4096 MB of GDDR6 memory. It features 1408 SPUs along with 88 TAUs and 32 Rasterization Operator Units.

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

Memory Bandwidth

The Radeon RX 5500 should in theory be a little bit faster than the Radeon RX 470 4GB in general. (explain)

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

Texel Rate

The Radeon RX 5500 will be quite a bit (approximately 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 much (more or less 80%) more effective at anti-aliasing than the Radeon RX 470 4GB, and should be capable of handling higher resolutions without losing too much performance. (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 max amount of data (in units of MB per second) that can be transported across the external memory interface in one second. It is worked out by multiplying the bus width by its memory clock speed. In the case of DDR type memory, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be processed per second. This is worked out by multiplying the total amount of texture units of the card by the core clock speed of the chip. The better this number, the better the graphics 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 that the graphics chip could possibly write to its local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the number of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate also depends on many other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
