Power Usage and Theoretical Benchmarks

Memory Bandwidth

The Radeon HD 6570 (OEM) 2GB should in theory be a lot faster than the GeForce 940M overall. (explain)

Radeon HD 6570 (OEM) 2GB		64000 MB/sec
GeForce 940M		16000 MB/sec
	Difference: 48000 (300%)

Texel Rate

The GeForce 940M should be quite a bit (approximately 65%) faster with regards to AF than the Radeon HD 6570 (OEM) 2GB. (explain)

GeForce 940M		25728 Mtexels/sec
Radeon HD 6570 (OEM) 2GB		15600 Mtexels/sec
	Difference: 10128 (65%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the GeForce 940M is superior to the Radeon HD 6570 (OEM) 2GB, by a large margin. (explain)

GeForce 940M		8576 Mpixels/sec
Radeon HD 6570 (OEM) 2GB		5200 Mpixels/sec
	Difference: 3376 (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 max amount of data (in units of megabytes per second) that can be transferred past the external memory interface in a second. It is calculated by multiplying the interface width by its memory speed. In the case of DDR memory, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be applied in one 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 the texel rate, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second.

Pixel Rate: Pixel rate is the most pixels that the graphics card can possibly record to its local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of Render Output Units 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 quite a few other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
