March 2008
Intel Corporation discussed upcoming leading edge microprocessors and technologies. Intel's 45nm high-k metal gate leading manufacturing technology is enabling the industry to move to multicore processors in all market segments, and Intel discussed future products with four, six, eight and many computing cores coming to the market.
Pat Gelsinger, Intel Senior Vice President and General Manager, Digital Enterprise Group:
Gelsinger disclosed details around Intel's multi-processor (MP) servers based on Intel's 6-core processor codenamed "Dunnington" and Intel's new Itanium processor codenamed "Tukwila." Gelsinger discussed current hot enterprise topics, including virtualization and the new SPEC power benchmark for measuring server energy efficiency, in which Intel-based systems hold all of the top 20 spots. He disclosed a number of technical features on two important products for Intel, Nehalem, Intel's next generation processor family and Larrabee, a future Intel product with many cores.
# Dunnington for Expandable (Multi-Processor) servers -- Intel's current 7300 chipset based platform combined with the Quad-Core Xeon 7300 processor is the industry's virtualization platform of choice for MP servers. Dunnington is socket-compatible with the Caneland platform and will be available in the second half of 2008. Dunnington is the first IA (Intel Architecture) processor with 6-cores, is based on the 45nm high-k process technology, and has large shared caches. Another supported feature is FlexMigration technology, which allows a single compatible virtualization pool that supports live VM (Virtual Machine) migration across both 65nm and 45nm high-k Intel Core™ microarchitecture-based servers and 45nm-based servers. This provides investment protection as well as the option to choose the right server platform to best optimize performance, cost, power and reliability.
# Tukwila delivers performance to the world's most powerful computers -- Tukwila is Intel's next-generation Itanium processor with four cores, 30MB total cache, QuickPath Interconnect, dual Integrated Memory Controller and mainframe-class RAS features. It is the world's first 2 billion transistor microprocessor and is projected to deliver more than double the performance of the current generation Itanium processor.
# Nehalem is Intel's dynamically scalable and innovative new processor microarchitecture -- Nehalem will provide dramatic performance and energy improvements to Intel's current industry-leading microprocessors. Nehalem is scalable with future versions having anywhere from 2 to 8 cores, with Simultaneous Multi-threading, resulting in 4 to 16 thread capability. Nehalem will deliver 4 times the memory bandwidth compared to today's highest-performance Intel Xeon processor-based systems. With up to 8 MB level-3 cache, 731 million transistors, Quickpath interconnects (up to 25.6GB per second), integrated memory controller and optional integrated graphics, Nehalem will eventually scale from notebooks to high-performance servers. Other features discussed include support for DDR3-800, 1066, and 1333 memory, SSE4.2 instructions, 32KB instruction cache, 32KB Data Cache, 256K L2 data and instruction low-latency cache per core and new 2-level TLB (Translation Lookaside Buffer) hierarchy. These technical improvements will result in performance improvements as well as flexibility for a wide range of eventual products based on the Nehalem architecture. Gelsinger also discussed the new Tylersburg platform, which can be configured for both one socket High End Desktop (HEDT) and two socket (HPC and dual processing server) operation.
