Few things.
Some people suggested that BIOS maybe the issue.
Well, boards are final and shipping, nobody in their right mind would ship a board to OEMs and even retail, with a claim about AM3+ compatibility if they would REQUIRE a bios flash after the client gets it.
JF insists that they dont cripple ES.
JF u sure ? Cause that doesnt tell a good story.
Because well, if bios aint broken, and the chip isnt.Its just BAD.
I know, u take as many chips as possible to get ES`s ,so clock wise, they can be very different from final product.
But they should perform clock for clock rather same.
Up until now, all ES`s ive seen had clock for clock very similar performance as the final product.
There were many issues, like low clocks, high volts, high TDP etc etc.But performance wasnt that drastically different.
And you say that AMD has only some basic idea about CPU performance before production ?!
Dont you guys simulate all the logic on these fancy hardware simulators big as hell which can simulate any processor albeit at MUCH lower speeds ?
And shouldnt you know your IPC targets for different workloads when the cpu is still on paper ?
Youre claims are kind of alarming.

@RussC

The thing is, in this day, pure performance doesnt really matter to the 80% of population.
"good enough" is the mantra for todays computing.
And even NOT good enough atom made a killing.
And now AMD makes a killing with zacate.
Simple example, if i offer my girlfriend a new laptop with sandybridge, which will be too slow to play sims 3 without choking, shes not going to be happy.If Llano will do that, shes going to opt for that.
And it doesnt matter that some tasks that she rarely does are going to be slower.Because gaming NEEDS some kind of performance, but with encoding a movie clip she an wait a minute instead of 30secs.
Llano will do good too.Although it needs cpu part to be revamped, but its coming next year.
Only problems may be with desktop/server part as we dont have BD numbers yet.

@Informal

Are there any pics of B1 in action from obr ? i cant find it.

@Jazkat

Trinity uses BD v1 .So the same arch as coming BD for am3+.
