Front-end bus architecture of the Swan six core Xeon CPU

Intel has just revealed a bit about the six-core Dunnington in the http://www.aliyun.com/zixun/aggregation/14435.html ">cebit 2008 Meeting" Xeon In the case of MP family processors, Singapore's renowned hardware site Vr-zone.com released a 2008-year Xeon MP processor's planned shipping ratio. Six of the core Dunnington will have a 23% share in the third quarter, which will reach 47% in the fourth quarter. The six core processors surfaced in this "no sign" situation, and we also hope to learn more about the six-core Dunnington Xeon MP family processor at the upcoming Spring 2008 meeting of the IDF.

As a successor to the 65 nm process Tigerton Xeon, the Dunnington Xeon MP processor has a thermal design that consumes no more than 130W of energy, uses the mPGA604 package format, and is compatible with the existing Tigerton Xeon series processors. Dunnington Xeon MP is still affiliated with the Penryn family, based on 45 nm high-k process design, three groups of shared 3MB two cache together to build 9MB, front-end bus frequency 1066MHz, support VT flexmigration virtualization technology, Supports 40bit physical addressing and SSE4 multimedia instruction sets, which will be made up of Caneland platforms with Clarksboro chipsets, mainly for rack-and-dense server domains.

Although the lack of strong competitors at this stage to eliminate the 45 nm process eight core processor reasons for the reason, but it is not good to control the core area and energy consumption is also an indisputable fact. To maintain the competitive edge of AMD's K10 Opteron family processor, Intel Dunnington Xeon MP changed its four core design to more than six sets of cores, plus AMD's "sword-walking Slant" Phenom X3 family, The law of "1-2-4-8" geometric increment of the core number of multi core processing is also broken.

The dispute over the "authenticity" of the core processor has been long-standing. In the early days of the dual-core processor, while the Athlon64 X2 family of AMD had a "real" double core, its system Request queue and crossbar connections were indeed superior, but the relatively high cost made it less than Intel's Pentium The D family came to "success". AMD's phenom family has once again sacrificed "real", but even Intel's Kentsfield/yorkfield is dubbed "glue Quad", but it does not seem to hinder its acceptance of the market, and "authenticity" The argument that there is no yardstick for the core of the issue has been dismissed.

Intel Corporation's six-core Dunnington Xeon MP family will continue to use the Multi-Chip module multi-chip modular design, three sets of dual cores are encapsulated in the same die, and with the 16MB shared three-level cache, respectively, occupy the die Four Corners, In the meantime, the logical bus is connected. At present, the single chip design is severely controlled by the process technology, Multi-Chip module, the application of multi-chip modular design has become more extensive, ATI new flagship display card R700 will also adopt this design.

Intel Corporation Nehalem Microarchitecture Processor will discard the many years of front Side bus FSB connection mode, the new QuickPath interconnect replaced, and Memory module controller, Graphics control unit and Pci-express bus, such as traditional North Bridge function "into" The CPU is not only multi-chip module chip modular design further application, but also marks the six core Dunnington Xeon MP family processors will most likely become the last batch of products using front Side bus FSB, while Intel desktop-level processors may be able to transition directly to the four core Lynnfield, the existing four Core 2 Extreme QX9770 processor will also be very likely to become the Penryn family desktop products of the shoulder tripod.
