Power Usage and Theoretical Benchmarks

Both cards have the same power consumption.

Memory Bandwidth

Theoretically speaking, the Radeon HD 6570 (OEM) 1GB will be 13% quicker than the GeForce 9500 GT 512MB GDDR3 in general, due to its higher bandwidth. (explain)

Radeon HD 6570 (OEM) 1GB		28800 MB/sec
GeForce 9500 GT 512MB GDDR3		25600 MB/sec
	Difference: 3200 (13%)

Texel Rate

The Radeon HD 6570 (OEM) 1GB will be quite a bit (about 77%) better at anisotropic filtering than the GeForce 9500 GT 512MB GDDR3. (explain)

Radeon HD 6570 (OEM) 1GB		15600 Mtexels/sec
GeForce 9500 GT 512MB GDDR3		8800 Mtexels/sec
	Difference: 6800 (77%)

Pixel Rate

The Radeon HD 6570 (OEM) 1GB should be a little bit (about 18%) more effective at AA than the GeForce 9500 GT 512MB GDDR3, and able to handle higher screen resolutions without losing too much performance. (explain)

Radeon HD 6570 (OEM) 1GB		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: Memory bandwidth is the max amount of information (in units of megabytes per second) that can be transported past the external memory interface in one second. It's worked out by multiplying the bus width by the speed of its memory. If it uses DDR memory, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip could possibly write to the local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate is also dependant on quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
