In theory, the GeForce GT 230 will be 33% faster than the Radeon HD 6570 (OEM) 1GB overall, because of its higher data rate. (explain)

GeForce GT 230		38400 MB/sec
Radeon HD 6570 (OEM) 1GB		28800 MB/sec
	Difference: 9600 (33%)

Texel Rate

The Radeon HD 6570 (OEM) 1GB is quite a bit (more or less 77%) better at anisotropic filtering than the GeForce GT 230. (explain)

Radeon HD 6570 (OEM) 1GB		15600 Mtexels/sec
GeForce GT 230		8800 Mtexels/sec
	Difference: 6800 (77%)

Pixel Rate

The Radeon HD 6570 (OEM) 1GB will be just a bit (about 18%) better at anti-aliasing than the GeForce GT 230, and able to handle higher screen resolutions more effectively. (explain)

Radeon HD 6570 (OEM) 1GB		5200 Mpixels/sec
GeForce GT 230		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 maximum amount of information (in units of megabytes per second) that can be transferred past the external memory interface in one second. It is worked out by multiplying the interface width by its memory speed. If the card has DDR memory, it should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the card's memory bandwidth, 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 in one second. This is worked out 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 handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second.

Pixel Rate: Pixel rate is the most pixels that the graphics chip could possibly record to its local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate also depends on many other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
