Radeon R9 270 vs Radeon RX 560

Intro

Compare all of that to the Radeon RX 560, which features GPU clock speed of 1175 MHz, and 4096 MB of GDDR5 RAM set to run at 1750 MHz through a 128-bit bus. It also is comprised of 1024 Stream Processors, 64 TAUs, and 16 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon RX 560		80 Watts
Radeon R9 270		150 Watts
	Difference: 70 Watts (88%)

Memory Bandwidth

The Radeon R9 270 should theoretically be quite a bit faster than the Radeon RX 560 overall. (explain)

Radeon R9 270		179200 MB/sec
Radeon RX 560		114688 MB/sec
	Difference: 64512 (56%)

Texel Rate

The Radeon RX 560 should be a little bit (more or less 4%) better at AF than the Radeon R9 270. (explain)

Radeon RX 560		75200 Mtexels/sec
Radeon R9 270		72000 Mtexels/sec
	Difference: 3200 (4%)

Pixel Rate

If using high levels of AA is important to you, then the Radeon R9 270 is the winner, and very much so. (explain)

Radeon R9 270		28800 Mpixels/sec
Radeon RX 560		18800 Mpixels/sec
	Difference: 10000 (53%)

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 information (counted in MB per second) that can be transferred across the external memory interface in a second. It is worked out by multiplying the card's interface width by the speed of its memory. In the case of DDR RAM, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, 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 amount of texture map elements (texels) that can be processed per second. This is worked out 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 graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second.

Pixel Rate: Pixel rate is the most pixels that the graphics card could possibly write to the local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate also depends on lots of other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
