GeForce GT 240 GDDR5 1GB vs Radeon RX 480

Intro

Compare those specs to the Radeon RX 480, which makes use of a 14 nm design. AMD has set the core frequency at 1120 MHz. The GDDR5 memory works at a frequency of 2000 MHz on this particular card. It features 2304 SPUs as well as 144 Texture Address Units and 32 Rasterization Operator Units.

GeForce GT 240 GDDR5 1GB		70 Watts
Radeon RX 480		150 Watts
	Difference: 80 Watts (114%)

Memory Bandwidth

Performance-wise, the Radeon RX 480 should in theory be a lot better than 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 will be a lot (more or less 816%) faster with regards to AF 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

The Radeon RX 480 is quite a bit (more or less 715%) better at AA than the GeForce GT 240 GDDR5 1GB, and also should be capable of handling higher resolutions better. (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 max amount of data (counted in MB per second) that can be moved over the external memory interface within a second. It is calculated by multiplying the interface width by its memory speed. In the case of DDR RAM, it must be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR 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 texture units of the card by the core speed of the chip. The higher the texel rate, the better the 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 the graphics card could possibly record to its local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - aka 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 max fill rate.
