Radeon RX 470 vs Radeon RX 5500

Intro

Compare those specs to the Radeon RX 5500, which has a clock speed of 1670 MHz and a GDDR6 memory speed of 1750 MHz. It also makes use of a 128-bit memory bus, and uses a 7 nm design. It is made up of 1408 SPUs, 88 Texture Address Units, and 32 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

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

Memory Bandwidth

Theoretically, the Radeon RX 5500 should perform just a bit faster than the Radeon RX 470 in general. (explain)

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

Texel Rate

The Radeon RX 5500 is a lot (approximately 24%) faster with regards to AF than the Radeon RX 470. (explain)

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

Pixel Rate

The Radeon RX 5500 should be quite a bit (about 80%) more effective at AA than the Radeon RX 470, and also should be capable of handling higher screen resolutions without slowing down too much. (explain)

Radeon RX 5500		53440 Mpixels/sec
Radeon RX 470		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: Memory bandwidth is the max amount of data (in units of MB per second) that can be transferred over the external memory interface in one second. It is worked out by multiplying the interface width by its memory speed. If the card has DDR type memory, it should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the card's 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 calculated by multiplying the total amount of texture units by the core clock speed of the chip. The higher the texel rate, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card can possibly write to the local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate also depends on quite a few other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the max fill rate.
