Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon HD 6570 (OEM) 2GB		50 Watts
GeForce GTX 965M		60 Watts
	Difference: 10 Watts (20%)

Memory Bandwidth

Both cards have the exact same bandwidth, so theoretically they should perform exactly the same. (explain)

Texel Rate

The GeForce GTX 965M is much (approximately 287%) faster with regards to anisotropic filtering than the Radeon HD 6570 (OEM) 2GB. (explain)

GeForce GTX 965M		60416 Mtexels/sec
Radeon HD 6570 (OEM) 2GB		15600 Mtexels/sec
	Difference: 44816 (287%)

Pixel Rate

The GeForce GTX 965M should be much (about 481%) better at anti-aliasing than the Radeon HD 6570 (OEM) 2GB, and will be able to handle higher screen resolutions without losing too much performance. (explain)

GeForce GTX 965M		30208 Mpixels/sec
Radeon HD 6570 (OEM) 2GB		5200 Mpixels/sec
	Difference: 25008 (481%)

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 largest amount of information (measured in MB per second) that can be transferred over the external memory interface in a second. It is worked out by multiplying the card's bus width by its memory speed. In the case of DDR RAM, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be processed per second. This is worked out by multiplying the total amount of texture units by the core clock speed of the chip. The better the texel rate, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.

Pixel Rate: Pixel rate is the most pixels the graphics card can possibly write to the local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the amount of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate is also dependant on many other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the max fill rate.
