Game debate is not the best site to compare hardware (CPUs/GPUs) it does have Decent Spec info on almost any SKU. Though it is known for misinformation. Either way When comparing GPUs from different architectures the outcome it is not relevant. Good example right there with the GT240 GDDR5 and the GT630. Lets say the Kepler one. Yes the GT240 has more texture units and GDDR5 memory. It is not a DX11 capable card, it is based Tesla which is a few architectures back. There is other sites that you can just key in a GPU vs another GPU and get benchmarks that are collected. AnandBench for example. Don't mean to call the site bad or anything as it is useful to an extent. For CPUs though CPU world or Wiki is good.
