Which is better?

Solution
Better for what?

It's also hard to answer because there are 96cuda and 384cuda versions of the GT630, whereas the GT710 has 192.

I believe the architecture is identical, so the GT630 with 384 cuda cores would be faster.

Having said that these are really only very light "gaming" cards suitable for games that are not very demanding.

If you want it for simple browsing, desktop usage etc then just get whatever is cheapest and has the monitor connections you need (or if you have an iGPU just use that)

GT 630 is definitely better, by all means [especially the kepler variant]
but i wouldn't by both if my focus is for gaming, i would try to get a 750ti / 1030 instead :) or if u can, a 1050 / 1050ti
 


and what conclusion is one supposed to draw from all these links with different results?

Be careful with a lot of those sites as many of them don't even give the full details of the cards they use, and also often just plug in numbers to GUESS at results without even doing actual benchmarks.
 


As you say, there are different versions of the GT630. One of them uses the same GPU as the GT710, the GK208. However, in the GT710 half the chip is disabled, while in the GT 630 it is intact (and the same is true of the GT 730).

There is another GT630 that uses the older GF108 chip and Fermi architecture. It has one quarter as many shaders, but Fermi does run with a shader hot clock that sort of means each shader counts double. The chip is still a lot weaker... but on the other hand, it has twice the memory bandwidth due to a 128-bit bus rather than 64-bit. That will often yield better performance at the end of the day.

And then there's yet another GT630 based on the GK107 chip. It's the same Kepler architecture as the GK208. However, it's a cut-down chip, and in this case it has half as many shaders and twice as many ROPs as the GK208-based GT630. It also has a 128-bit memory bus, which again will be a big advantage in most situations.

Overall it's a mess. OP would need to confirm what the memory bus width is quoted at, or some other detailed specs, because as it stands there's no way to say which GT630 version is on offer, and how it would compare to the GT710.
