GeForce GT 240 GDDR5 1GB vs Radeon RX 480

Intro

Compare those specs to the Radeon RX 480, which comes with a GPU core clock speed of 1120 MHz, and 8192 MB of GDDR5 RAM set to run at 2000 MHz through a 256-bit bus. It also is made up of 2304 SPUs, 144 Texture Address Units, and 32 ROPs.

Radeon RX 480		150 Watts
	Difference: 80 Watts (114%)

Memory Bandwidth

As far as performance goes, the Radeon RX 480 should theoretically be much superior to the GeForce GT 240 GDDR5 1GB in general. (explain)

Radeon RX 480		262144 MB/sec
GeForce GT 240 GDDR5 1GB		54400 MB/sec
	Difference: 207744 (382%)

Texel Rate

The Radeon RX 480 should be quite a bit (approximately 816%) more effective at texture filtering than the GeForce GT 240 GDDR5 1GB. (explain)

Radeon RX 480		161280 Mtexels/sec
GeForce GT 240 GDDR5 1GB		17600 Mtexels/sec
	Difference: 143680 (816%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the Radeon RX 480 is a better choice, by a large margin. (explain)

Radeon RX 480		35840 Mpixels/sec
GeForce GT 240 GDDR5 1GB		4400 Mpixels/sec
	Difference: 31440 (715%)

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 (in units of MB per second) that can be moved over the external memory interface in a second. The number is calculated by multiplying the interface width by its memory clock speed. If it uses DDR RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher 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 amount of texture map elements (texels) that can be processed per second. This number is worked out by multiplying the total amount of texture units of the card by the core speed of the chip. The higher this number, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second.

Pixel Rate: Pixel rate is the most pixels that the graphics chip can possibly record to its local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the number of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate is also dependant on quite a few other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
