Radeon HD 5570 vs Radeon RX 470

Intro

Compare those specs to the Radeon RX 470, which comes with a core clock frequency of 926 MHz and a GDDR5 memory speed of 1650 MHz. It also uses a 256-bit memory bus, and uses a 14 nm design. It is comprised of 2048 SPUs, 128 TAUs, and 32 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon HD 5570		43 Watts
Radeon RX 470		120 Watts
	Difference: 77 Watts (179%)

Memory Bandwidth

The Radeon RX 470 should in theory be a lot faster than the Radeon HD 5570 overall. (explain)

Radeon RX 470		211200 MB/sec
Radeon HD 5570		28800 MB/sec
	Difference: 182400 (633%)

Texel Rate

The Radeon RX 470 will be quite a bit (more or less 812%) better at texture filtering than the Radeon HD 5570. (explain)

Radeon RX 470		118528 Mtexels/sec
Radeon HD 5570		13000 Mtexels/sec
	Difference: 105528 (812%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the Radeon RX 470 is a better choice, by far. (explain)

Radeon RX 470		29632 Mpixels/sec
Radeon HD 5570		5200 Mpixels/sec
	Difference: 24432 (470%)

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 information (counted in megabytes per second) that can be moved past the external memory interface within a second. It's calculated by multiplying the interface width by its memory speed. If it uses DDR type RAM, it must be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the card's 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 amount of texture map elements (texels) that can be applied in one second. This figure is worked out by multiplying the total amount of texture units by the core speed of the chip. The better this number, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second.

Pixel Rate: Pixel rate is the most pixels that the graphics card could possibly record to the local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the number of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate is also dependant on lots of other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
