GeForce GT 340		69 Watts
Radeon HD 3650 512MB		78 Watts
	Difference: 9 Watts (13%)

Memory Bandwidth

In theory, the GeForce GT 340 should be quite a bit faster than the Radeon HD 3650 512MB overall. (explain)

GeForce GT 340		54400 MB/sec
Radeon HD 3650 512MB		25600 MB/sec
	Difference: 28800 (113%)

Texel Rate

The GeForce GT 340 is a lot (approximately 203%) faster with regards to anisotropic filtering than the Radeon HD 3650 512MB. (explain)

GeForce GT 340		17600 Mtexels/sec
Radeon HD 3650 512MB		5800 Mtexels/sec
	Difference: 11800 (203%)

Pixel Rate

The GeForce GT 340 will be quite a bit (about 52%) more effective at anti-aliasing than the Radeon HD 3650 512MB, and also should be able to handle higher screen resolutions without losing too much performance. (explain)

GeForce GT 340		4400 Mpixels/sec
Radeon HD 3650 512MB		2900 Mpixels/sec
	Difference: 1500 (52%)

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 max amount of information (in units of megabytes per second) that can be moved past the external memory interface in one second. The number is worked out by multiplying the interface width by its memory speed. In the case of DDR memory, it should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed per second. This is calculated by multiplying the total number of texture units of the card by the core speed of the chip. The higher this number, the better the 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 number of pixels that the graphics card could 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 colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate also depends on lots of other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
