Power Usage and Theoretical Benchmarks

Memory Bandwidth

In theory, the GeForce GTX 480 will be 1132% quicker than the Radeon R5 M330 overall, due to 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 should be much (about 104%) more effective at 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

The GeForce GTX 480 should be quite a bit (about 308%) faster with regards to full screen anti-aliasing than the Radeon R5 M330, and also capable of handling higher screen resolutions without losing too much performance. (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: Bandwidth is the largest amount of data (in units of MB per second) that can be transferred across the external memory interface in one second. The number is calculated by multiplying the card's interface width by its memory speed. If it uses DDR memory, it should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the bandwidth is, 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 number of texture map elements (texels) that are applied per second. This number is worked out by multiplying the total number of texture units of the card by the core speed of the chip. The better the texel rate, the better the 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 the video card could possibly record to the local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate is also dependant on quite a few other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
