Intel alters server processor roadmap

Intel announced several changes Monday to its road map for server processors, delaying its first dual-core Itanium 2 processor
and replacing a future multicore Xeon processor with a new design that eliminates the performance penalty of shared connections
to a chipset.
Montecito, the dual-core version of the Itanium 2 processor, will not be available in large volumes until the middle of next
year, instead of the early part of next year as originally planned, said Scott McLaughlin, an Intel spokesman. While preliminary
shipments of the processor are already under way, Intel decided to make a few changes to the chip in order to reach the company's
standard for "production level quality," McLaughlin said, declining to specify the nature of the changes.
But Montecito will no longer ship with Foxton, a sophisticated power-management technology, and the speed of its front-side
bus connection to memory will run at 533 MHz instead of the 667 MHz speed originally scheduled for the design, he said.
Intel also has killed Whitefield, a multicore Xeon processor for servers with four or more processors, McLaughlin said. It
is being replaced by a new processor called Tigerton that will appear in 2007, the same time-frame in which Whitefield was
expected to arrive.
Tigerton processors will use a high-speed interconnect technology that will allow each processor to connect directly to the
server's chipset, McLaughlin said. Current Xeon processors in multiprocessor servers must share a front-side bus connection
to the chipset in order to access data from system memory or I/O, a bottleneck that industry analysts have blamed for the
current performance gap between Intel's server chips and Advanced Micro Devices' Opteron processors.
Intel's next-generation architecture , announced by President and CEO Paul Otellini in August, will be used as the blueprint for Tigerton. This architecture is
based on low-power design principles used to build Intel's Pentium M processor for notebooks.
Whitefield had been expected to help tip the performance battle back toward Intel in 2007, but Tigerton should be even more
powerful, McLaughlin said. AMD has enjoyed favorable reviews from industry analysts, and even companies such as HP, for the
performance of its Opteron server processors as compared to Intel's Xeon chips.
Intel is not specifying exactly how the Tigerton processors will connect to the server's chipset, such as whether they will
use integrated memory or I/O controllers or a next-generation interconnect technology that Intel has vaguely discussed at
previous Intel Developer Forums.
The Caneland platform, or the combination of Tigerton and its related chipset, is not the design that will bring socket compatibility
to Intel's Xeon and Itanium processors, McLaughlin said. Intel wants to make a chipset that can accommodate either a Xeon
processor or an Itanium processor, which will help reduce product development costs for both Intel and its partners. That
compatibility is slated to arrive along with Tukwila, a multicore Itanium 2 processor now scheduled to arrive in 2008 as a
result of the Montecito delay, he said. Intel is still evaluating when its Xeon processors will be designed for that compatibility.
