Radeon HD 5750 512MB		73600 MB/sec
Radeon R5 M330		14400 MB/sec
	Difference: 59200 (411%)

Texel Rate

The Radeon HD 5750 512MB is quite a bit (about 22%) faster with regards to AF than the Radeon R5 M330. (explain)

Radeon HD 5750 512MB		25200 Mtexels/sec
Radeon R5 M330		20600 Mtexels/sec
	Difference: 4600 (22%)

Pixel Rate

If running with a high screen resolution is important to you, then the Radeon HD 5750 512MB is superior to the Radeon R5 M330, by a large margin. (explain)

Radeon HD 5750 512MB		11200 Mpixels/sec
Radeon R5 M330		8240 Mpixels/sec
	Difference: 2960 (36%)

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 data (measured in MB per second) that can be transferred over the external memory interface in a second. It is calculated by multiplying the interface width by its memory clock speed. If it uses DDR memory, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better 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 are processed in one second. This is calculated by multiplying the total texture units by the core speed of the chip. The better the texel rate, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.

Pixel Rate: Pixel rate is the most pixels that the graphics card can possibly write to its local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as 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, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
