Power Usage and Theoretical Benchmarks

Memory Bandwidth

The GeForce GT 315, in theory, should perform much faster than the Radeon R5 M330 overall. (explain)

GeForce GT 315		25280 MB/sec
Radeon R5 M330		14400 MB/sec
	Difference: 10880 (76%)

Texel Rate

The Radeon R5 M330 should be a lot (more or less 106%) better at anisotropic filtering than the GeForce GT 315. (explain)

Radeon R5 M330		20600 Mtexels/sec
GeForce GT 315		10000 Mtexels/sec
	Difference: 10600 (106%)

Pixel Rate

If using a high screen resolution is important to you, then the Radeon R5 M330 is the winner, by far. (explain)

Radeon R5 M330		8240 Mpixels/sec
GeForce GT 315		5000 Mpixels/sec
	Difference: 3240 (65%)

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 maximum amount of information (measured in megabytes per second) that can be transferred over the external memory interface in a second. The number is worked out by multiplying the bus width by the speed of its memory. In the case of DDR RAM, the result should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card can possibly write 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 core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate is also dependant on lots of other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the max fill rate.
