Intel Demos Dual-Core Itanium 2 Processors.Next Year's IA64 Chips on TrackCategory: CPU by Anton Shilov [ 06/19/2004 | 06:13 PM ]
Intel Corporation showcased a wafer with dual-core Intel Itanium 2 “Montecito” dies at an event in
Dual-Core, DDR2, PCI Express Ahead Montecito will be Intel’s first IA64 chip with two cores and 24MB of L3 cache. In 2003 Intel uncovered plans to implement its special “arbiter” bus into the chip code-named Montecito to manage how the cores collaborate between themselves, how they utilise their processor system bus and the L3 cache. No actual peculiarities of the design have been presented by Intel officials so far, but we can pre-suppose that the “arbiter” bus architecture may be utilised in all multiple-core CPUs from Intel that will come in future.
The Montecito and Intel’s Itanium 2 chips with two processing engine will work using 667MHz Quad Pumped Bus and will feature Intel’s new core-logic for high-end servers code-named Bayshore. The latter is expected to provide support for DDR2 memory and PCI Express interconnection, bringing the latest innovations into the server market. First Wafers Showcased As expected, Intel will produce the Montecito using its 90nm fabrication technology utilizing 300mm wafers. The company demonstrated the first wafers with dual-core Itanium 2 dies, indicating that the prototypes had been manufactured and now Intel may even test the actual dual-core microprocessors.
Each dual-core Itanium 2 “Montecito” with 24MB of cache is expected to contain about 1.7 billion of transistors, about 13 times more than modern Intel Pentium 4 chips include. Shortly Intel is projected to release a faster version of its current incarnation of the Itanium 2 processors – the product code-named In the longer term Intel gears toward processors that contain more than two cores. The first of the company’s multi-core IA64 processors is code-named Tukwila (formerly Tanglewood). Eventually, there will also be a chip code-named Dimona, a yet another multi-core offspring of the Itanium 2. Both are anticipated for release in 2006 and later. Related news
