GeForce GT 230		38400 MB/sec
	Difference: 73600 (192%)

Texel Rate

The Radeon RX 460 2GB should be quite a bit (about 594%) more effective at anisotropic filtering than the GeForce GT 230. (explain)

Radeon RX 460 2GB		61040 Mtexels/sec
GeForce GT 230		8800 Mtexels/sec
	Difference: 52240 (594%)

Pixel Rate

The Radeon RX 460 2GB should be a lot (more or less 296%) more effective at anti-aliasing than the GeForce GT 230, and also able to handle higher resolutions without slowing down too much. (explain)

Radeon RX 460 2GB		17440 Mpixels/sec
GeForce GT 230		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 information (counted in MB per second) that can be moved past the external memory interface within a second. The number is worked out by multiplying the bus width by its memory speed. If it uses DDR type memory, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the memory bandwidth, 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 amount of texture map elements (texels) that are processed per second. This number is worked out by multiplying the total amount of texture units by the core clock speed of the chip. The better the texel rate, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip can possibly write to the local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of Render Output Units 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 rate is also dependant on lots of other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
