Power Usage and Theoretical Benchmarks

Both cards have the same power consumption.

Memory Bandwidth

The Radeon HD 6570 (OEM) 2GB should theoretically be quite a bit faster than the GeForce 9500 GT 512MB GDDR3 in general. (explain)

Radeon HD 6570 (OEM) 2GB		64000 MB/sec
GeForce 9500 GT 512MB GDDR3		25600 MB/sec
	Difference: 38400 (150%)

Texel Rate

The Radeon HD 6570 (OEM) 2GB should be much (about 77%) more effective at texture filtering than the GeForce 9500 GT 512MB GDDR3. (explain)

Radeon HD 6570 (OEM) 2GB		15600 Mtexels/sec
GeForce 9500 GT 512MB GDDR3		8800 Mtexels/sec
	Difference: 6800 (77%)

Pixel Rate

The Radeon HD 6570 (OEM) 2GB should be a bit (about 18%) more effective at full screen anti-aliasing than the GeForce 9500 GT 512MB GDDR3, and capable of handling higher screen resolutions while still performing well. (explain)

Radeon HD 6570 (OEM) 2GB		5200 Mpixels/sec
GeForce 9500 GT 512MB GDDR3		4400 Mpixels/sec
	Difference: 800 (18%)

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 megabytes per second) that can be transferred across the external memory interface in a second. It's worked out by multiplying the card's bus width by its memory speed. If the card has DDR type memory, it should be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the bandwidth is, the faster 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 number of texture map elements (texels) that are applied per second. This number is worked out by multiplying the total texture units by the core clock 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 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 calculated by multiplying the amount of Render Output Units by the the core speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate is also dependant on many other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
