Radeon R7 240 vs Radeon RX 560

Intro

Compare all that to the Radeon RX 560, which comes with a core clock frequency of 1175 MHz and a GDDR5 memory speed of 1750 MHz. It also makes use of a 128-bit bus, and uses a 14 nm design. It features 1024 SPUs, 64 Texture Address Units, and 16 ROPs.

Radeon R7 240		14600 Mtexels/sec
	Difference: 60600 (415%)

Pixel Rate

The Radeon RX 560 will be quite a bit (more or less 222%) more effective at full screen anti-aliasing than the Radeon R7 240, and capable of handling higher resolutions more effectively. (explain)

Radeon RX 560		18800 Mpixels/sec
Radeon R7 240		5840 Mpixels/sec
	Difference: 12960 (222%)

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 largest amount of data (counted in megabytes per second) that can be moved past the external memory interface in a second. It is worked out by multiplying the card's interface width by the speed of its memory. If it uses DDR memory, the result should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels the video card could possibly write to the local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate also depends on quite a few other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the max fill rate.
