Radeon HD 3470 512MB vs Radeon RX 550

Intro

Compare those specs to the Radeon RX 550, which uses a 14 nm design. AMD has clocked the core frequency at 1100 MHz. The GDDR5 RAM works at a frequency of 1750 MHz on this specific model. It features 512 SPUs along with 32 TAUs and 16 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

The Radeon RX 550 should theoretically be quite a bit faster than the Radeon HD 3470 512MB overall. (explain)

Radeon RX 550		114688 MB/sec
Radeon HD 3470 512MB		30400 MB/sec
	Difference: 84288 (277%)

Texel Rate

The Radeon RX 550 should be much (about 1000%) better at texture filtering than the Radeon HD 3470 512MB. (explain)

Radeon RX 550		35200 Mtexels/sec
Radeon HD 3470 512MB		3200 Mtexels/sec
	Difference: 32000 (1000%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the Radeon RX 550 is a better choice, by a large margin. (explain)

Radeon RX 550		17600 Mpixels/sec
Radeon HD 3470 512MB		3200 Mpixels/sec
	Difference: 14400 (450%)

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 (counted in megabytes per second) that can be transported over the external memory interface in a second. It is worked out by multiplying the card's interface width by the speed of its memory. If it uses DDR memory, it should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are applied 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 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 most pixels the video card could possibly write to its local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of Render Output Units 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 is also dependant on many other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
