"Conroe" is an eighth-generation x86 architecture microprocessor produced by Intel and is their first all-new CPU design since the Netburst architecture of 2000. As of now, little is known about Conroe, but the Conroe architecture will be revealed throughout the Fall Intel Developer Forum (IDF) 2005 (the Fall 2005 IDF is over. Could somebody update this please?). Intel plans to ship Conroe architecture chips codenamed "Allendale" in the latter half of 2006 using the 65nm process.

Technology

The 8th generation processor architecture is a heavily engineered core similar to the Pentium M but designed from the ground up. The data pipeline is 14 stages; a far cry from the 31 of Prescott. The new architecture is a dual core design with linked L1 cache and shared L2 cache.

New technologies included in the design are Macro-Ops Fusion, similar to Micro-Ops Fusion, and a new power saving design; the default stage for all components is minimum speed, allowing the chip to produce a minimum of heat whenever possible. The front side bus for this new architecture is targetted to run at 1333 Mhz for the Woodcrest server and workstation segment and 1066 Mhz for Merom, the mobile variant. Conroe is officially slated to run at 1066MHz, but may well end up at 1333Mhz. Unfortunately, the FSB is the weak link in the new architecture, as it uses the infrastructure installed in the Pentium 4 Era which cannot handle the full bandwidth of dual-channel DDR2 SDRAM. Front Side Bus (FSB) is the term used to describe the CPU data bus. ... Pentium 4 (with hyper-threading) brand logo The Pentium 4 is a seventh-generation x86 architecture microprocessor produced by Intel and is their first all-new CPU design since the Pentium Pro of 1995. ... DDR2 SDRAM (Double Data Rate Two Synchronous Dynamic Random Access Memory) is a computer memory technology that, as of 2005, is becoming the mainstream standard for personal computer memory. ...


Floating point performance is expected to be weaker than that of the Athlon 64/Opteron series of processors due to the shorter pipeline, but other operations are predicted to be much faster, around 30% clock per clock over Netburst. It has been suggested that Athlon 64 X2 be merged into this article or section. ... The AMD Opteron is the first eighth-generation x86 processor (K8 core), and the first of AMDs AMD64 (x86-64) processors, released April 22, 2003. ... The NetBurst Microarchitecture is the name given to the new architecture that succeded the P6 microarchitecture in the x86 family of CPUs made by Intel. ...


Intel says that the power consumption of these new processors is to be extremely low; average use energy consumption is to be in the 1-2 watt range, with TDPs of 65 watts for Conroe and 80 watts for Woodcrest. However, this is subject to change. Merom, the mobile variant, is listed at 35 watts TDP for standard versions and 5 watts TDP for Ultra Low Voltage (ULV) versions. The Thermal Design Point or Thermal Design Power (TDP) represents the maximum amount of power the thermal solution in a computer system is required to dissipate. ...


As predicted, performance advertising has taken a secondary role with Intel, and a new philosophy of "Performance per Watt" is taking center stage. However, integer performance still plays a role differentiating Conroe from its competition. Intel Corporation (NASDAQ: INTC) (founded 1968) is a U.S.-based multinational corporation that is best known for designing and manufacturing microprocessors and specialized integrated circuits. ...


Variations

The Conroe architecture is one of three seperate architectures divided up into mobile, desktop, and server processing solutions.

  • Merom is for mobile processing
  • Conroe is designed for desktops
  • Woodcrest is a server processor

It is uncertain at this time how Intel will continue its brand name heritage in this new architecture. The Celeron brand traditionally represents cores with disabled L2 cache, which may possibly continue in the Conroe architecture which is expected to have between four and eight megabytes of L2 cache. Intel Corporation (NASDAQ: INTC) (founded 1968) is a U.S.-based multinational corporation that is best known for designing and manufacturing microprocessors and specialized integrated circuits. ... 633MHz Celeron A Celeron is any of a large number of different budget x86 microprocessors produced by Intel and marketed as a budget/value CPU line. ...


The Xeon line will likely continue as Woodcrest in 2007 due to back compatibility with Intel's pending Irwindale platform and the strength of the Xeon brand name.

It is known that Conroe will be back compatible with some of the LGA-775 chipsets on the market, but a final brand name for this new chip has not been decided upon. Intels latest Socket for a processor is Socket T, or, LGA 775. ...
