B0's show up as "Model 2, Stepping 0"Originally Posted by informal
These results are "Model 2, Stepping 1", i.e., they are B1 results.

So,all pre-B2 were buggy.

We heard that AMD partners has gotten B1-step Barcelona for compatibility testing with better and newer AGESA code compared to the B0-step Barcelona. There is also B2-step Barcelona which is bug free and then BA-step Barcelona for mass production
AMD is LAUNCHING the K10 on the B1 stepping, per everyone else. Then B2 in Q4. At any rate, it is unlikely that B1 has any huge performance bugs. These results fit precisely with what AMD themselves claimed.... up to 10-15% better IPC than the K8. About in the ballpark of Conroe/Kentsfield per clock. Better on some bandwidth-heavy server stuff & HPC, worse on desktop apps.

It is hard to determine what stepping this site is showing, if it is real (my little disclaimer).... but there is a hint.
The CPUID string that CPUID read from BIOS does not read "AMD Opteron processor unknown" or "Engineering Sample (ES)".... AMD uses a special registers, which the BIOS reads and constructs the processor name and model string, and information.... see for example, page 345 http://www.amd.com/us-en/assets/cont...docs/32559.pdf
The CPUID report from Coolaler's site correctly identifies the processor family as 10, and also does not read the CPUID string as anything other than the branded processor name....
Assuming this is not faked (which is well could be), it appears to be the release product.
