Radeon R5 M330		14400 MB/sec
	Difference: 113728 (790%)

Texel Rate

The GeForce GTX 560 should be quite a bit (about 120%) better at anisotropic filtering than the Radeon R5 M330. (explain)

GeForce GTX 560		45360 Mtexels/sec
Radeon R5 M330		20600 Mtexels/sec
	Difference: 24760 (120%)

Pixel Rate

If running with a high screen resolution is important to you, then the GeForce GTX 560 is superior to the Radeon R5 M330, by a large margin. (explain)

GeForce GTX 560		25920 Mpixels/sec
Radeon R5 M330		8240 Mpixels/sec
	Difference: 17680 (215%)

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 maximum amount of information (measured in MB per second) that can be transferred past the external memory interface in a second. It is calculated by multiplying the card's bus width by its memory speed. In the case of DDR type RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the memory bandwidth, the better 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 can be processed in one second. This figure is worked out by multiplying the total number of texture units by the core clock speed of the chip. The higher this number, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip could possibly record to the local memory in a second - measured in millions of pixels per second. The number is worked out 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 rate also depends on many other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
