The Radeon RX 560 will be a lot (more or less 194%) better at anisotropic filtering than the Radeon HD 7750. (explain)

Radeon RX 560		75200 Mtexels/sec
Radeon HD 7750		25600 Mtexels/sec
	Difference: 49600 (194%)

Pixel Rate

The Radeon RX 560 is much (approximately 47%) faster with regards to full screen anti-aliasing than the Radeon HD 7750, and will be capable of handling higher resolutions without slowing down too much. (explain)

Radeon RX 560		18800 Mpixels/sec
Radeon HD 7750		12800 Mpixels/sec
	Difference: 6000 (47%)

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: Memory bandwidth is the max amount of data (in units of MB per second) that can be transferred across the external memory interface in one second. The number is calculated by multiplying the card's bus width by its memory clock speed. If it uses DDR memory, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied per second. This figure is calculated by multiplying the total number of texture units of the card by the core clock speed of the chip. The better the texel rate, the better the graphics card will be at handling 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 could possibly write to the local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate also depends on quite a few other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
