Power Usage and Theoretical Benchmarks

Memory Bandwidth

In theory, the GeForce GT 320 should perform quite a bit faster than the Radeon R5 M330 in general. (explain)

GeForce GT 320		25280 MB/sec
Radeon R5 M330		14400 MB/sec
	Difference: 10880 (76%)

Texel Rate

The Radeon R5 M330 will be a lot (approximately 59%) more effective at AF than the GeForce GT 320. (explain)

Radeon R5 M330		20600 Mtexels/sec
GeForce GT 320		12960 Mtexels/sec
	Difference: 7640 (59%)

Pixel Rate

The Radeon R5 M330 should be a lot (approximately 91%) more effective at AA than the GeForce GT 320, and should be capable of handling higher screen resolutions without slowing down too much. (explain)

Radeon R5 M330		8240 Mpixels/sec
GeForce GT 320		4320 Mpixels/sec
	Difference: 3920 (91%)

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 (measured in megabytes per second) that can be moved across the external memory interface in a second. It is worked out by multiplying the card's interface width by its memory clock speed. If it uses DDR RAM, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the better the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are processed per second. This number is worked out by multiplying the total amount of texture units by the core speed of the chip. The better this number, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second.

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card could possibly write to the local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the number of Render Output Units by the the core speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate is also dependant on many other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the max fill rate.
