Power Usage and Theoretical Benchmarks

Both cards have the same power consumption.

Memory Bandwidth

As far as performance goes, the Radeon HD 6570 (OEM) 2GB should theoretically be a lot superior to the GeForce 9500 GT 1GB GDDR3 overall. (explain)

Radeon HD 6570 (OEM) 2GB		64000 MB/sec
GeForce 9500 GT 1GB GDDR3		25600 MB/sec
	Difference: 38400 (150%)

Texel Rate

The Radeon HD 6570 (OEM) 2GB should be quite a bit (more or less 77%) more effective at AF than the GeForce 9500 GT 1GB GDDR3. (explain)

Radeon HD 6570 (OEM) 2GB		15600 Mtexels/sec
GeForce 9500 GT 1GB GDDR3		8800 Mtexels/sec
	Difference: 6800 (77%)

Pixel Rate

The Radeon HD 6570 (OEM) 2GB is just a bit (more or less 18%) faster with regards to AA than the GeForce 9500 GT 1GB GDDR3, and should be capable of handling higher resolutions better. (explain)

Radeon HD 6570 (OEM) 2GB		5200 Mpixels/sec
GeForce 9500 GT 1GB 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: Memory bandwidth is the maximum amount of information (measured in MB per second) that can be transported over the external memory interface in one second. It is worked out by multiplying the card's bus width by the speed of its memory. If the card has DDR RAM, it must be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the better 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 texture map elements (texels) that are applied per second. This figure is worked out by multiplying the total texture units of the card by the core clock speed of the chip. The higher this number, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card could possibly record to its local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of colour ROPs by the the core clock speed. 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 is also dependant on lots of other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
