GeForce GT 240 GDDR5 1GB vs Radeon RX 560

Intro

Compare those specs to the Radeon RX 560, which has a clock frequency of 1175 MHz and a GDDR5 memory frequency of 1750 MHz. It also uses a 128-bit memory bus, and uses a 14 nm design. It is made up of 1024 SPUs, 64 TAUs, and 16 ROPs.

GeForce GT 240 GDDR5 1GB		70 Watts
Radeon RX 560		80 Watts
	Difference: 10 Watts (14%)

Memory Bandwidth

As far as performance goes, the Radeon RX 560 should in theory be quite a bit superior to the GeForce GT 240 GDDR5 1GB overall. (explain)

Radeon RX 560		114688 MB/sec
GeForce GT 240 GDDR5 1GB		54400 MB/sec
	Difference: 60288 (111%)

Texel Rate

The Radeon RX 560 is quite a bit (more or less 327%) more effective at anisotropic filtering than the GeForce GT 240 GDDR5 1GB. (explain)

Radeon RX 560		75200 Mtexels/sec
GeForce GT 240 GDDR5 1GB		17600 Mtexels/sec
	Difference: 57600 (327%)

Pixel Rate

The Radeon RX 560 should be much (approximately 327%) more effective at AA than the GeForce GT 240 GDDR5 1GB, and also able to handle higher screen resolutions more effectively. (explain)

Radeon RX 560		18800 Mpixels/sec
GeForce GT 240 GDDR5 1GB		4400 Mpixels/sec
	Difference: 14400 (327%)

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 data (counted in megabytes per second) that can be moved past the external memory interface in one second. It is calculated by multiplying the bus width by its memory clock speed. If it uses DDR type RAM, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the bandwidth is, the faster 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 are applied per second. This number is calculated by multiplying the total texture units by the core clock 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 in one second.

Pixel Rate: Pixel rate is the most pixels that the graphics card could possibly record to its local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the number of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to 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 bandwidth is, the lower the potential to get to the maximum fill rate.
