go back one post.

B1 is DVT and not production release.

Just confirmed that B1 IS the stepping on currently available Barcelonas. We won't be seeing B2's until AMD starts ramping up the speeds on quads; as evidenced by Anandtech's EARLY Phenom chip.

But that Dave Graham guy was swearing up and down that B1 had some performance crippling bug, how could they be shipping that? Or is the Dave Graham guy full of crap?

Oh wait, here was his original post on the subject:

So that performance crippling bug that he claimed invalidated the the Coolaler benchies was a bug that impacted a single set of obscure memory bandwidth benchmarks (http://www.streambench.org/) that I'd never even heard of before.

LOL

nope.

BA is the fixed B1 rev that patches AMD errata 281 (stream, int, float performance). No production systems will use B1 chips. PERIOD. straight from AMD's mouth about 30 minutes ago from the field application engineer who has to support this. All review systems that you've seen have utilized a BIOS patch to workaround the errata which does in fact impact performance.

B2 is the mask revision for higher speed parts. AMD will announce these in Q4 and ship for rev. either at the end of Dec. or Jan. these will be 2.5 and 2.6 parts.

cheers,

So we will see a inproved preformace with reatail systems! Good to know I supose that dualcore K10 (Kuma?) will be B2 aswell? Just looked at asus Rd790 borad, looks nice but not "finished" Hope to see a Dual K10 borad from Dfi to, now THAT would rock! In the mean time I just have to play with my new 6400+, hopfully tomorow

If you wanna see the new DFI board for the K10, then you should look here

It seems strange that AMD have been shipping BA chips to customers for a while and then supply bugged B1 chips to the reviewers fixed by a BIOS patch. Something does not add up there.

I have an idea:
Steve and Dave, you 2 guys need to get together for a weekend and I think at the end many issues would be solved.
Dave, weather is probably better in Cal than the monsoon we've had for the last 3 days..
Go west young man, Go west!

I'm a little supprised at this also, but maybe they want to keep true benchmarks secret just a little longer
