Radeon HD 5570 vs Radeon RX 460

Intro

The Radeon HD 5570 comes with a GPU clock speed of 650 MHz, and the 512 MB of DDR3 memory runs at 900 MHz through a 128-bit bus. It also features 400(80x5) SPUs, 20 TAUs, and 8 ROPs.

Compare all of that to the Radeon RX 460, which features core clock speeds of 1090 MHz on the GPU, and 1750 MHz on the 4096 MB of GDDR5 RAM. It features 896 SPUs along with 56 Texture Address Units and 16 Rasterization Operator Units.

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

Texel Rate

The Radeon RX 460 will be much (approximately 370%) better 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 running with high levels of AA is important to you, then the Radeon RX 460 is superior to the Radeon HD 5570, 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.

Memory Bandwidth: Memory bandwidth is the maximum amount of data (counted in MB per second) that can be transported past the external memory interface in one second. The number is calculated by multiplying the interface width by its memory clock speed. If the card has DDR memory, it should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be processed 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 higher this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second.

Pixel Rate: Pixel rate is the most pixels the video 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 number of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate is also dependant on quite a few other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
