Electronista reports that HP has upgraded their workstations with the new Intel Penryn Xeon processors. The new 45-nm Xeon 5200 (dual core) and Xeon 5400 (quad core) processors can be configured in dual-processor configurations (up to 8 cores total).
Yesterday, Lenovo announced their first machines powered by the Intel Xeon 5400 processors. These new Penryn based PCs, however, are not expected to ship until January 2008.
Intel will be officially launching the Penryn processors on November 12th. Apple is expected to adopt the new procesors in a revision to the Mac Pro. The new Mac Pro is rumored to be ready to launch as soon as enough Intel processors become available.
