Radeon HD 5570 vs Radeon RX 460

Intro

Compare those specs to the Radeon RX 460, which features a clock speed of 1090 MHz and a GDDR5 memory frequency of 1750 MHz. It also uses a 128-bit bus, and uses a 14 nm design. It is comprised of 896 SPUs, 56 Texture Address Units, 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 perform much faster than the Radeon HD 5570 overall. (explain)

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

Texel Rate

The Radeon RX 460 should be quite a bit (approximately 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

If using lots of anti-aliasing is important to you, then the Radeon RX 460 is a better choice, by far. (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 MB per second) that can be moved over the external memory interface in a second. The number is worked out by multiplying the card's bus width by the speed of its memory. If it uses DDR type RAM, the result should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card can possibly record to its local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate also depends 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.
