So 1.8 TFLOP > 8 TFLOp(HD 7990)?

No it will never happen...

What the consoles did better than PC is to use the 1.8 TFLOPS better than 2.5 TFLOPS for example... is is like the console uses 90% of 1.8 FLOPS and a PC uses 50% of 2.5 TFLOPS... there are a lot of overhead in PC not present in consoles.

In raw power the GPU on PC will be always more powerful but the result will just be noticiable in way more powerful GPU like GTX 680, HD 7970, HD 7790, etc...

Anyway the HD 7790 is a dual-gpu that uses Crossfire to work... the Crossfire is even less eficient than SLI... so the unused raw power in this GPU is even bigger than HD 7970 (single-gpu).

I agree with the overhead argument on windows PCs using DX.  Steam and nvidia did an interesting presentation on porting to OpenGL and linux which showed a massive improvement in gaming performance on the same hardware (which is why the Steambox will be linux based).

There may be a small gain from the unified memory as well with the PS4 but it won't make up the considerable lag in graphic performange of the AMD APU line vs current dedicated cards from AMD and NVIDIA.

True. Being quite a PC retrogamer and trying always to build a low power consumption PC, though, I'm very happy anyway of the side effects of all this on near future entry level PCs, my next one will be able to handle very good graphics (for my tastes graphics noticeably better than 7th gen consoles are more than enough) even without adding a dedicated graphics card. Adding one, the APU's GPU could be used as physics accelerator, if both drivers and games will support it.
