GeForce GT 240 GDDR5		54400 MB/sec
	Difference: 57600 (106%)

Texel Rate

The Radeon RX 460 2GB should be much (approximately 247%) better at anisotropic filtering than the GeForce GT 240 GDDR5. (explain)

Radeon RX 460 2GB		61040 Mtexels/sec
GeForce GT 240 GDDR5		17600 Mtexels/sec
	Difference: 43440 (247%)

Pixel Rate

The Radeon RX 460 2GB is much (more or less 296%) faster with regards to full screen anti-aliasing than the GeForce GT 240 GDDR5, and also should be capable of handling higher screen resolutions without losing too much performance. (explain)

Radeon RX 460 2GB		17440 Mpixels/sec
GeForce GT 240 GDDR5		4400 Mpixels/sec
	Difference: 13040 (296%)

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 data (measured in MB per second) that can be transferred past the external memory interface in a second. The number is worked out by multiplying the card's interface width by its memory clock speed. If it uses DDR type RAM, the result should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are applied per second. This number is calculated by multiplying the total amount of texture units by the core speed of the chip. The better the texel rate, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card can possibly write to its local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the number of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate is also dependant on quite a few other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
