Power Usage and Theoretical Benchmarks

Memory Bandwidth

In theory, the Radeon HD 3650 256MB should perform much faster than the Radeon R7 M260 in general. (explain)

Radeon HD 3650 256MB		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%) faster with regards to anisotropic filtering than the Radeon HD 3650 256MB. (explain)

Radeon R7 M260		17160 Mtexels/sec
Radeon HD 3650 256MB		5800 Mtexels/sec
	Difference: 11360 (196%)

Pixel Rate

If using high levels of AA is important to you, then the Radeon R7 M260 is a better choice, by far. (explain)

Radeon R7 M260		5720 Mpixels/sec
Radeon HD 3650 256MB		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: Bandwidth is the maximum amount of information (in units of MB per second) that can be moved over the external memory interface within a second. The number is calculated by multiplying the interface width by the speed of its memory. If the card has DDR memory, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher 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 number is calculated by multiplying the total amount of texture units of the card by the core clock speed of the chip. The better this number, the better the graphics card will be at 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 its local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the number of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate also depends on lots of other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
