The GeForce GTX 1050 3GB should in theory perform a lot faster than the Radeon HD 3470 512MB overall. (explain)

GeForce GTX 1050 3GB 86016 MB/sec
Radeon HD 3470 512MB 30400 MB/sec
Difference: 55616 (183%)

Texel Rate

The GeForce GTX 1050 3GB will be quite a bit (approximately 1988%) faster with regards to anisotropic filtering than the Radeon HD 3470 512MB. (explain)

GeForce GTX 1050 3GB 66816 Mtexels/sec
Radeon HD 3470 512MB 3200 Mtexels/sec
Difference: 63616 (1988%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the GeForce GTX 1050 3GB is a better choice, and very much so. (explain)

GeForce GTX 1050 3GB 33408 Mpixels/sec
Radeon HD 3470 512MB 3200 Mpixels/sec
Difference: 30208 (944%)

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 largest amount of information (measured in megabytes per second) that can be moved past the external memory interface within a second. It is worked out by multiplying the interface width by the speed of its memory. If it uses DDR RAM, the result should be multiplied by 2 once 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 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 number 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 texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second.

Pixel Rate: Pixel rate is the most pixels that the graphics card can possibly write to the local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the number of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate is also dependant on lots of other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
