Radeon HD 5570 vs Radeon RX 460

Intro

Compare that to the Radeon RX 460, which uses a 14 nm design. AMD has clocked the core speed at 1090 MHz. The GDDR5 RAM works at a frequency of 1750 MHz on this particular card. It features 896 SPUs as well as 56 TAUs and 16 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon HD 5570		43 Watts
Radeon RX 460		75 Watts
	Difference: 32 Watts (74%)

Memory Bandwidth

Theoretically, the Radeon RX 460 should be quite a bit faster than the Radeon HD 5570 in general. (explain)

Radeon RX 460		112000 MB/sec
Radeon HD 5570		28800 MB/sec
	Difference: 83200 (289%)

Texel Rate

The Radeon RX 460 is much (about 370%) more effective at anisotropic filtering than the Radeon HD 5570. (explain)

Radeon RX 460		61040 Mtexels/sec
Radeon HD 5570		13000 Mtexels/sec
	Difference: 48040 (370%)

Pixel Rate

The Radeon RX 460 should be a lot (about 235%) faster with regards to full screen anti-aliasing than the Radeon HD 5570, and also should be capable of handling higher screen resolutions while still performing well. (explain)

Radeon RX 460		17440 Mpixels/sec
Radeon HD 5570		5200 Mpixels/sec
	Difference: 12240 (235%)

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 maximum amount of information (measured in megabytes per second) that can be transferred past the external memory interface within a second. It's calculated by multiplying the card's bus width by its memory clock speed. If the card has DDR type RAM, the result should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are applied per second. This is calculated by multiplying the total texture units of the card by the core speed of the chip. The higher the texel rate, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second.

Pixel Rate: Pixel rate is the most pixels that the graphics chip could possibly record to its local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of Raster Operations Pipelines by the the core 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 quite a few other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
