Power Usage and Theoretical Benchmarks

Memory Bandwidth

The GeForce GT 220 GDDR3, in theory, should perform quite a bit faster than the Radeon R5 M330 in general. (explain)

GeForce GT 220 GDDR3		32384 MB/sec
Radeon R5 M330		14400 MB/sec
	Difference: 17984 (125%)

Texel Rate

The Radeon R5 M330 is quite a bit (more or less 106%) more effective at texture filtering than the GeForce GT 220 GDDR3. (explain)

Radeon R5 M330		20600 Mtexels/sec
GeForce GT 220 GDDR3		10000 Mtexels/sec
	Difference: 10600 (106%)

Pixel Rate

If using a high screen resolution is important to you, then the Radeon R5 M330 is superior to the GeForce GT 220 GDDR3, by far. (explain)

Radeon R5 M330		8240 Mpixels/sec
GeForce GT 220 GDDR3		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 largest amount of data (in units of megabytes per second) that can be transferred past the external memory interface in one second. The number is calculated by multiplying the bus width by its memory speed. In the case of DDR type memory, the result should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied per second. This figure is worked out by multiplying the total number of texture units by the core clock speed of the chip. The better this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a 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 number is worked out by multiplying the number of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate is also dependant on many other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
