After numerous delays the Phenom finally shipped late last year, but suffered an immediate set back due to the TLB errata issue. This certainly didn't help AMD pull off a stellar launch, but the issue has been fixed in the new B3 series K10 CPUs.
“In addition to fixing the TLB race condition, AMD will finally increase the core frequency of the Opteron series on the B3 stepping. After the initial OEM orders are filled, channel vendors like Newegg and TigerDirect will carry the new Opterons in frequencies ranging from 1.8 GHz to 2.4 GHz. Vendor estimates put this e-tailer ship date in early April.”
The Barcelona K10s might end up with a relatively short lifespan as rumors persist that the upgraded 45nm K10, codenamed Shanghai, will ship later this year.
