Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically speaking, the Radeon R7 250 is 411% quicker than the Radeon R5 M330 overall, because of its higher data rate. (explain)

Radeon R7 250		73600 MB/sec
Radeon R5 M330		14400 MB/sec
	Difference: 59200 (411%)

Texel Rate

The Radeon R7 250 is a small bit (approximately 17%) better at AF than the Radeon R5 M330. (explain)

Radeon R7 250		24000 Mtexels/sec
Radeon R5 M330		20600 Mtexels/sec
	Difference: 3400 (17%)

Pixel Rate

The Radeon R5 M330 should be just a bit (more or less 3%) more effective at FSAA than the Radeon R7 250, and also will be capable of handling higher resolutions better. (explain)

Radeon R5 M330		8240 Mpixels/sec
Radeon R7 250		8000 Mpixels/sec
	Difference: 240 (3%)

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 (counted in megabytes per second) that can be moved past the external memory interface in one second. It is worked out by multiplying the card's interface width by its memory speed. If it uses DDR type memory, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher 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 amount of texture map elements (texels) that are processed per second. This figure is worked out by multiplying the total number of texture units of the card by the core speed of the chip. The better this number, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.

Pixel Rate: Pixel rate is the most pixels that the graphics chip can possibly write to its local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the amount of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate also depends on many other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
