Power Usage and Theoretical Benchmarks

Memory Bandwidth

The Radeon HD 5850 should theoretically be a lot faster than the Radeon R5 M330 in general. (explain)

Radeon HD 5850		128000 MB/sec
Radeon R5 M330		14400 MB/sec
	Difference: 113600 (789%)

Texel Rate

The Radeon HD 5850 will be much (about 153%) more effective at anisotropic filtering than the Radeon R5 M330. (explain)

Radeon HD 5850		52200 Mtexels/sec
Radeon R5 M330		20600 Mtexels/sec
	Difference: 31600 (153%)

Pixel Rate

If running with high levels of AA is important to you, then the Radeon HD 5850 is superior to the Radeon R5 M330, and very much so. (explain)

Radeon HD 5850		23200 Mpixels/sec
Radeon R5 M330		8240 Mpixels/sec
	Difference: 14960 (182%)

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 (measured in MB per second) that can be moved past the external memory interface within a second. It is worked out by multiplying the card's interface width by the speed of its memory. In the case of DDR type memory, the result 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 number of texture map elements (texels) that can be processed per second. This is worked out by multiplying the total 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 applied per second.

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card can possibly record to the local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of Render Output Units by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate also depends on many other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the max fill rate.
