I've read the architecture preview of Bulldozer architecture and it at the same time looks promising compared to the current gen Nehalem architecture but also not so promising regarding the facts that two processing core block will share the same FPU. It looks like their main concern is to create a Processor block with very low power consumption rather than sheer performance. All their preview releases are also displayed exceptionally good Power handling, in fact their current generation 45 nm 6 cores show exceptional good TDP.
I have doubt whether their processors can beat Sandy bridge if Intel has done some thing that truly excels over Nehalem architecture.

agreed, the newer architecture looks good,at least what all i understood, got me a bit excited
The only thing that really suxs - launch date - Q2 2011, LGA 2011 chips will be out by then,god knows what a processor will do with so many pins

The i3's are selling rapidly so amd didn't exactly beat intel in entry level scenario.Same is for the mobile segment. In midrange you have the i5 7 series but 6 series is utter flop.
And in top segment the gulftowns are scorchers but do cost more cause there is no competition. I would be delighted( heck all consumers will) if amd target that and does it successfully which it hasn't done so far. Thats a territory untouched by the competition. So the i7's are still at the top of the food chain whereas thubans give better vfm. Expect bulldozer to spice things of with its advanced threading capabilities and shared FP scheduler, but it has one tough opponent to beat namely SANDYBRIDGE.
@ Ishu gupta
Yes unfortunately Amd doesn't sell well is due to bad rumors. Even in my city people rarely buy amd as the dealer doesn,t encourage them. Same in the laptop segment but expect things to change in the upcoming zacate and ontario platforms.
AMD should market products properly like intel if it want to sway buyers from the opposition's camp.

afaik, Bulldozer is NOT fusion. Bulldozer is a processor and for the first time AMD has made full architectural changes since Athlon 64 aka K8 in 2003. Till now AMD was just making evolutionary changes in that K8 architecture and surviving the fight. This time they are developing a processor completely from scratch. It is just like Intel when they moved from Pentium to Core.
AMD Fusion products (AMD is calling them APUs) as of now are Brazos (Ontario 9W TDP and Zacate 18W TDP) and Llano. Bobcat (CPU of the APU) is for netbooks/low-end notebooks and Zacate has actually raped Intel Atom in benchmarks.
Bulldozer based Fusion products will be out in 2012.

Imagine...netbooks can game too now.
Major win imho.Actually, sharing FPU is the thing which is promising. The two processing core blocks are a single module (bhai-bhai). It is their answer to Intel's hyper-threading and it will be much faster (imo
) but with more die space.It will be like this...a Bulldozer processor which has "4 Bulldozer cores" will be treated by the OS as 8 cores.

In Bulldozer you can see both the threads are getting their own integer scheduler compared to hyper-threading in which they are sharing.

oH OK I get that. So initial batches won't get the apu. Then it will be one on one mano e mano battle between bulldozer and sandybridge to prove whose the leader in pure computation.
Fusion is a part of bulldozer right?
And low end brazos parts have on die graphics which amd calls apu( accelerated processing unit) right?

At the moment, they are different products. Bulldozer is just a processor and Fusion is APU as AMD calls it.
Correct.
the early samples of the zacate have been reviewed, they perform well, the the processor is about 50% faster than the amd neo and in graphics,it matched the ion 2 platform and it seems that it will be much better as those were real early drivers. Hope they come out in Q1 next year...

Well Intel does not tell a hyper threaded core as dual core. It is single core with a thread register to hold two threads. AMD's counter attack would have ben much more interesting if they call their two shared processing cores as one core and a dual core has 2 of these modules.

@Cilus, yes. Intel HT is a virtual thing, kind of. AMD made it real. but how well will it scale in single threaded apps? cause you getting kind of more cores ultimately.
@Ico, Bulldozer is an architecture or its a processor (like Phenom II, Athlon II)? Fusion is will unite GPU + CPU producing APU.
also can anyone clarify which processors of the upcoming Bulldozer family as well as Fusion will be made in 40nm & which in 32nm? the latter Fusion II will be made in 32nm (Krishna, Trinity, Wichita and Komodo.......). but what about the current fusion as well as bulldozer parts?
