Much of the speculation is embarrassing in this thread.
First, it has some serious decoding power (4 complex-ops or "cops" and in some cases 4+1 decode) and in total a massive front-end to keep up feeding two integer execution units, which more guarantees it's throughput to a single ALU. With that said, singelthreaded performance will not be bad. How it will do in 4+ threads, it will still be better then SMT.
The FPU, it's since long time very clear that it is very powerful and flexible. It will be as good or better than the one in Sandy Bridge.
Also the cacheprefetchers should be very aggressive and some singelthreaded games should see some great speed.
Don't forget the additional performance improvement in total from the Turbomode in 1-4 threaded load, which will give ~15% plus.
Be patient, soon it's here, and also the numbers.
And OBR... I have no word for so much time spent on nothing. Don't write about him.
