Radeon RX 460 2GB		112000 MB/sec
Radeon HD 5750 1GB		73600 MB/sec
	Difference: 38400 (52%)

Texel Rate

The Radeon RX 460 2GB will be a lot (more or less 142%) more effective at anisotropic filtering than the Radeon HD 5750 1GB. (explain)

Radeon RX 460 2GB		61040 Mtexels/sec
Radeon HD 5750 1GB		25200 Mtexels/sec
	Difference: 35840 (142%)

Pixel Rate

The Radeon RX 460 2GB should be much (more or less 56%) more effective at full screen anti-aliasing than the Radeon HD 5750 1GB, and also should be capable of handling higher screen resolutions more effectively. (explain)

Radeon RX 460 2GB		17440 Mpixels/sec
Radeon HD 5750 1GB		11200 Mpixels/sec
	Difference: 6240 (56%)

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 information (in units of megabytes per second) that can be transported over the external memory interface in one second. The number is worked out by multiplying the card's bus width by the speed of its memory. If the card has DDR memory, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied in one second. This figure is worked out by multiplying the total amount of texture units by the core clock speed of the chip. The higher the texel rate, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card can possibly write to its local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the amount of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate is also dependant on lots of other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
