*Barcelona shipping in standard/low power are "planned for shipment for launch later this summer"
*Shipping in August for revenue, systems equipped with K10 in September
*"launch up to 2.0 Ghz"
*Higher frequencies in Q4
standard/low power at 1.9-2.0 means that's not the highest clock they could squeeze out of the chips.
Though, this is server, most of us want the Desktop part, comming with "higher frequencies in Q4".
