GeForce GT 240 GDDR5 1GB vs Radeon RX 560

Intro

Compare those specifications to the Radeon RX 560, which comes with a GPU core 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 made up of 1024 Stream Processors, 64 TAUs, and 16 Raster Operation Units.

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

Memory Bandwidth

The Radeon RX 560 should in theory perform a lot faster than the GeForce GT 240 GDDR5 1GB in general. (explain)

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

Texel Rate

The Radeon RX 560 will be quite a bit (approximately 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

If running with lots of anti-aliasing is important to you, then the Radeon RX 560 is superior to the GeForce GT 240 GDDR5 1GB, by far. (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: Bandwidth is the maximum amount of information (counted in megabytes per second) that can be moved across the external memory interface in one second. It's worked out by multiplying the bus width by its memory clock speed. If it uses DDR type memory, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the bandwidth is, 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 texture map elements (texels) that can be processed per second. This figure is calculated by multiplying the total 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 in one second.

Pixel Rate: Pixel rate is the maximum amount of pixels the video card can possibly write to the local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate also depends on lots of other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
