Power Usage and Theoretical Benchmarks

Memory Bandwidth

In theory, the GeForce GTX 480 will be 1132% quicker than the Radeon R5 M330 in general, because of its higher bandwidth. (explain)

GeForce GTX 480		177408 MB/sec
Radeon R5 M330		14400 MB/sec
	Difference: 163008 (1132%)

Texel Rate

The GeForce GTX 480 is much (about 104%) faster with regards to texture filtering than the Radeon R5 M330. (explain)

GeForce GTX 480		42000 Mtexels/sec
Radeon R5 M330		20600 Mtexels/sec
	Difference: 21400 (104%)

Pixel Rate

If using a high resolution is important to you, then the GeForce GTX 480 is a better choice, and very much so. (explain)

GeForce GTX 480		33600 Mpixels/sec
Radeon R5 M330		8240 Mpixels/sec
	Difference: 25360 (308%)

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 (measured in megabytes per second) that can be transferred across the external memory interface within a second. It's calculated by multiplying the card's bus width by the speed of its memory. If it uses DDR RAM, the result should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the bandwidth is, the faster 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 applied in one second. This is worked out by multiplying the total number of 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 in a second.

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