We know that Barcelona works and runs benchmarks, as we saw back at AMD in May. But the demos that AMD ran were on its own motherboards, not on motherboards from its partners. AMD's partners just recently received their first Barcelona samples, and as expected, the boards require some heavy BIOS work before the new chips will even work.
The motherboard we tested on had minimal HT functionality and wouldn't run at memory speeds faster than DDR2-667; most video cards wouldn't even work in the motherboard. Memory performance was just atrocious on the system, but the motherboard manufacturer we were working with attributed this to a BIOS issue that it expects to be fixed in the very near future.
