Intel showed off two Blackford two-way dual-core Xeon systems at Tyan's and Asus' booth at Computex. The one at Tyan's booth was already running for two days and had two dual-core 3.73GHz Xeon 'Dempsey' processors with 1MB L2 cache per core. These upcoming dual-core Xeon processors have a 1066MHz FSB.
The Blackford chipset uses the new LGA771 Xeon processors and gives each socket its own FSB, this means the bandwidth won't be shared by two sockets. Blackford will probably be released within two months. More info and photos at The Inquirer
