The GeForce GTX 750 Ti should in theory be quite a bit faster than the Radeon HD 3470 512MB in general. (explain)

GeForce GTX 750 Ti		86400 MB/sec
Radeon HD 3470 512MB		30400 MB/sec
	Difference: 56000 (184%)

Texel Rate

The GeForce GTX 750 Ti is a lot (more or less 1175%) faster with regards to AF than the Radeon HD 3470 512MB. (explain)

GeForce GTX 750 Ti		40800 Mtexels/sec
Radeon HD 3470 512MB		3200 Mtexels/sec
	Difference: 37600 (1175%)

Pixel Rate

The GeForce GTX 750 Ti should be quite a bit (approximately 410%) faster with regards to FSAA than the Radeon HD 3470 512MB, and capable of handling higher screen resolutions without slowing down too much. (explain)

GeForce GTX 750 Ti		16320 Mpixels/sec
Radeon HD 3470 512MB		3200 Mpixels/sec
	Difference: 13120 (410%)

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 max amount of information (measured in megabytes per second) that can be moved past the external memory interface in a second. The number is worked out by multiplying the card's bus width by its memory clock speed. If it uses DDR RAM, the result should be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the bandwidth is, the faster the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip can possibly write to its local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number 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 output rate also depends on many other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the max fill rate.
