Power Usage and Theoretical Benchmarks

Memory Bandwidth

The Radeon HD 3650 512MB, in theory, should perform quite a bit faster than the Radeon R7 M260 overall. (explain)

Radeon HD 3650 512MB		25600 MB/sec
Radeon R7 M260		16000 MB/sec
	Difference: 9600 (60%)

Texel Rate

The Radeon R7 M260 is a lot (more or less 196%) more effective at anisotropic filtering than the Radeon HD 3650 512MB. (explain)

Radeon R7 M260		17160 Mtexels/sec
Radeon HD 3650 512MB		5800 Mtexels/sec
	Difference: 11360 (196%)

Pixel Rate

The Radeon R7 M260 should be a lot (more or less 97%) better at anti-aliasing than the Radeon HD 3650 512MB, and also able to handle higher resolutions without slowing down too much. (explain)

Radeon R7 M260		5720 Mpixels/sec
Radeon HD 3650 512MB		2900 Mpixels/sec
	Difference: 2820 (97%)

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 max amount of data (in units of megabytes per second) that can be transported across the external memory interface within a second. The number is worked out by multiplying the interface width by its memory clock speed. In the case of DDR RAM, it 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 are applied in one second. This number is calculated by multiplying the total 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 applied in one second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip can possibly write to the local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of colour 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 output rate is also dependant on quite a few other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
