Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically speaking, the Radeon HD 3470 256MB should be 6% quicker than the Radeon HD 6570 (OEM) 1GB in general, because of its higher bandwidth. (explain)

Radeon HD 3470 256MB 30400 MB/sec
Radeon HD 6570 (OEM) 1GB 28800 MB/sec
Difference: 1600 (6%)

Texel Rate

The Radeon HD 6570 (OEM) 1GB is quite a bit (approximately 388%) faster with regards to AF than the Radeon HD 3470 256MB. (explain)

Radeon HD 6570 (OEM) 1GB 15600 Mtexels/sec
Radeon HD 3470 256MB 3200 Mtexels/sec
Difference: 12400 (388%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the Radeon HD 6570 (OEM) 1GB is a better choice, by a large margin. (explain)

Radeon HD 6570 (OEM) 1GB 5200 Mpixels/sec
Radeon HD 3470 256MB 3200 Mpixels/sec
Difference: 2000 (63%)

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.

Memory Bandwidth: Memory bandwidth is the max amount of data (measured in megabytes per second) that can be transported past the external memory interface in a second. It's calculated by multiplying the interface width by its memory clock speed. If it uses DDR type RAM, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the most pixels the video card can possibly write to the local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the amount of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate is also dependant on quite a few other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the max fill rate.
