Benchmarketing or not, if AMD wants any profit, it can't sell narrow-niche product like A-series Opteron for the same price as wider-niche based-on-existing-tech X-series Opteron. They would want to sell it for $150 at least. But $150 BD-based Opterons are in completely different league performance wise. And even faster $200 Xeon-E3s (e.g. E3-1220 v3) waiting just around the corner.
