The GF is just now getting up and running. It needs time to get everything in order plus they have yet to be able to get HK/MG working. Last report I saw, IBM was having touble with it and I doubt they will just get it down pat. Intel was working on it for quite along time (since before Core 2 came out) so they have the lead there.
We will have to see if anything they "promise" will come. I don't take it as a promise though because that just leads to being let down. I prefer to think of it as things they are going to try to do. But if they can improve the IPC they just might be able to beat out C2Q and give Core i5 a run for its money.
IBM's approach is gate-first HKMG, Intel's is gate-last, so whatever Intel learned probably won't be useable by IBM/AMD. In part, the 1000 degree C annealing process means IBM had to go with a different mix - Intel's wouldn't stand the heat
so to speak.
IIRC games are primarily integer code, so FP improvement (or SSE, etc) wouldn't help much except maybe on some game threads such as physics...
Finally, I doubt AMD could do much for IPC without a substantially different core architecture. You can do some things like throw more cache or high-speed, low latency memory access to reduce bottlenecks, but internal to the core would require far more than just a new stepping.
Finally finally
, one reason why the Core2 march has higher IPC is that it has 4-issue decoders, instead of the 3 that AMD's K8, K10, K10.5, etc use. There are other advantages such as better OoO execution, too, although K10 has made significantly progress there I believe, compared to K8.
