Dude, never compare FLOPS of two different architectures and make conclusions from that - PS4/XOne are GCN, 360 is old VLIW5.

Here, this will help, it's represents aggregate of lot of benchmarks for gfx cards, so comparison is pretty easy with it (360 is around 12VP):

Interesting table... now tell me how you calculate this 12VP to 360 GPU?

Because if that table is right the 360 GPU is more close to 18VP than 12VP.

Edit - Just to be clear the 360 GPU is equivalent to Radeon X1800.

No, not really, it is based on similar architecture, specially TMU and ROP, but shader units have more in common with R600 (2xxx) family. If you look at 2600Pro/XT, 360 is basically 2 of those slapped together, but at lower clock and significantly lower combined memory bandwidth. Some math and educated guesstimation are required to get to that number at the end.

Actual performance is higher of course, but considering we can't really measure how much specific customizations play role in final products, taking just vanilla numbers is a good starting point for the sake of discussion (hence, 141VP of 7850 for PS4, and 96VP of 7770 for XOne, though in reality, both solutions perform lot better).
