Radeon HD 3470 512MB 30400 MB/sec
GeForce 9500 GT 512MB GDDR3 25600 MB/sec
Difference: 4800 (19%)

Texel Rate

The GeForce 9500 GT 512MB GDDR3 is a lot (approximately 175%) faster with regards to anisotropic filtering than the Radeon HD 3470 512MB. (explain)

GeForce 9500 GT 512MB GDDR3 8800 Mtexels/sec
Radeon HD 3470 512MB 3200 Mtexels/sec
Difference: 5600 (175%)

Pixel Rate

The GeForce 9500 GT 512MB GDDR3 should be much (about 38%) more effective at anti-aliasing than the Radeon HD 3470 512MB, and capable of handling higher resolutions more effectively. (explain)

GeForce 9500 GT 512MB GDDR3 4400 Mpixels/sec
Radeon HD 3470 512MB 3200 Mpixels/sec
Difference: 1200 (38%)

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: Bandwidth is the largest amount of data (measured in MB per second) that can be moved past the external memory interface within a second. It's calculated by multiplying the bus width by its memory clock speed. If it uses DDR memory, it must be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card can possibly write to its local memory in a second - measured in millions of pixels per second. The figure is calculated 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 outputting the pixels (image) to the screen. The actual pixel output rate also depends on quite a few other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the max fill rate.
