Radeon R7 240 vs Radeon RX 560

Intro

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

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon R7 240		30 Watts
Radeon RX 560		80 Watts
	Difference: 50 Watts (167%)

Memory Bandwidth

The Radeon RX 560, in theory, should perform quite a bit faster than the Radeon R7 240 overall. (explain)

Radeon RX 560		114688 MB/sec
Radeon R7 240		28800 MB/sec
	Difference: 85888 (298%)

Texel Rate

The Radeon RX 560 should be much (approximately 415%) better at texture filtering than the Radeon R7 240. (explain)

Radeon RX 560		75200 Mtexels/sec
Radeon R7 240		14600 Mtexels/sec
	Difference: 60600 (415%)

Pixel Rate

If using a high screen resolution is important to you, then the Radeon RX 560 is a better choice, and very much so. (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: Memory bandwidth is the largest amount of information (in units of MB per second) that can be transferred across the external memory interface in one second. The number is worked out by multiplying the interface width by its memory clock speed. If the card has DDR type RAM, it must be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the faster the card will be in general. It especially helps with AA, HDR and high 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 by the core clock speed of the chip. The higher this number, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip can possibly record to its local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the amount of ROPs by the the core speed of the card. 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 many other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
