Power Usage and Theoretical Benchmarks

Both cards have the same power consumption.

Memory Bandwidth

The Radeon HD 6570 (OEM) 1GB should theoretically be a small bit faster than the GeForce 9500 GT 1GB GDDR3 in general. (explain)

Radeon HD 6570 (OEM) 1GB		28800 MB/sec
GeForce 9500 GT 1GB GDDR3		25600 MB/sec
	Difference: 3200 (13%)

Texel Rate

The Radeon HD 6570 (OEM) 1GB should be quite a bit (approximately 77%) better at AF than the GeForce 9500 GT 1GB GDDR3. (explain)

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

Pixel Rate

The Radeon HD 6570 (OEM) 1GB should be just a bit (about 18%) faster with regards to anti-aliasing than the GeForce 9500 GT 1GB GDDR3, and will be capable of handling higher screen resolutions more effectively. (explain)

Radeon HD 6570 (OEM) 1GB		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 max amount of information (counted in megabytes per second) that can be moved over the external memory interface within a second. It's calculated by multiplying the interface width by its memory clock speed. In the case of DDR RAM, it should 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 AA, High Dynamic Range and high resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card could possibly record to the local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the number of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate also depends on quite a few other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
