total power. Epic games mentioned that number. 1.8 is fine I guess.
edit
Last week Epic Games CEO Tim Sweeney told DICE 2012 attendees that the tech demo of Unreal Engine 3 released last year, called "Samaritan," required 2.5 terraFLOPS to run at a 1920 x 1080 resolution, 30 frames per second and with 48 operations per pixel (that rig was a monster in size too). By comparison, Microsoft's Xbox 360 console is only capable of .25 terraFLOPS, meaning Microsoft will need to generate a new console at least ten times more powerful in order to run the UE3 demo smoothly.
O well Samaritan looked cool...
This is funny thing with using peak SP tf - those are 100% achievements (no card ever gets that). A GPU cannot exceed those limits.
So a 2.5 tfp APU won't be able to handle it. In real world circumstances, even 7 years down the line, a 2.5 tf won't hit it's peak. A really efficient one will probably hit 2tf.
However, Samaritan can be optimised and the demo will probably run on lower specs.
Or a 3 tfp gpu (FMA) such as the GTX 680.
If we could find an inxpensive way to cool these chips down, then maybe, value being thrown out the window (as well as any other kind of budget), you could have had a 680
in a console releasing this year.
