Product Features

 Eight Core

— Eight complete 64-bit processing cores on one

processor, with two threads per core.

— Each core provides in-order issue and execution

of up to twelve instructions per cycle.

— Includes dynamic domain partitioning and static

hard partitioning.

 Advanced EPIC (Explicitly Parallel Instruction

Computing) Architecture for current and future

requirements of high-end enterprise and technical

workloads.

— Provide a variety of advanced implementations of

parallelism, predication, and speculation,

resulting in superior Instruction-Level Parallelism

(ILP).

 Intel

Hyper-Threading Technology

— Dual Domain Multithreading with independent

front end and back end thread domains providing

hardware support for 2 threads per core.

— Support for Intel

Itanium

Processor New-

Instructions.

 Wide, parallel hardware based on Intel

Itanium

architecture for high performance:

— Integrated on-die LLC cache of up to 32MB;

cache hints for FLC, MLC, and LLC caches for

reduced memory latency.

— 160 general and 128 floating-point registers

supporting register rotation.

— Register stack engine for effective management

of processor resources.

— Support for predication and speculation.

 Extensive RAS features for business-critical

applications, for example:

— Machine check architecture with extensive ECC

and parity protection with firmware first error

handling.

— End-to-end error detection.

— On-chip thermal management and power

management.

— Built-in processor information ROM (PIROM).

— Built-in programmable EEPROM.

—Hot Plug Socket.

— Hot-add and hot removal support.

— Double Device Data Correction (DDDC) for x4

DRAMs, plus correction support of a single bit

error.

— Single Device Data Correction (SDDC) for x8 and

x4 DRAMs, plus correction of a single bit error.

cleanup.

 Two On-die Memory Controllers

— Each memory controller supports two Intel

Scalable Memory Interconnects that operate in

lockstep.

— Support for one Scalable Memory Buffer per Intel

Scalable Memory Interconnect; four Scalable

Memory Buffers per processor.

— High memory bandwidth, thus improved

performance.

— 4.8 GT/s for the Intel

7500 Scalable Memory

Buffer.

— 6.4 GT/s for the Intel

7510 Scalable Memory

Buffer.

 Intel

VT) for

Intel

64 or Itanium

architecture (Intel

Vt-i) 3 -

Virtualization Support Extensions for Intel

Virtualization Technology.

— Reduce virtualization complexity.

— Improve virtualization performance via hardware

optimization.

— Increase operating system compatibility.

 Intel

Cache Safe Technology ensure mainframe-

caliber availability.

— Minimize LLC cache errors.

— Disable cache entries that have become hard

errors.

— Directory Cache covers 33% more cache lines.

— Improve availability.

 High bandwidth Intel

QuickPath Interconnect for

multiprocessor scalability:

— 4 full and 2 half width Intel QPI Links

— 6.4GT/s transfer rate with aggregate data

bandwidth of 28.8 GB/s.

— Systems are easily scaled without sacrificing

performance.

 Features to support flexible platform environments:

— Fully compatible with binaries for the Intel

Itanium processor family with Instruction level

advancements.

— LGA1248 Socket Level compatible with the Intel

Itanium

Processor 9300 Series.

— Bi-endian support.

— Processor abstraction layer eliminates processor

dependencies.
