INTRODUCTION
 Seeing the technical difficulties in cranking
  higher clock speed out of the present single
  core processors, dual core architecture has
  started to establish itself as the answer to
  the development of future processors.
 With the release of AMD dual core opteron
  and Intel Pentium Extreme edition 840, the
  month of April 2005 officially marks the
  beginning of dual core endeavors for both
  companies.

TRANSITION FROM SINGLE
CORE TO DUAL CORE
The transition from a single core to dual
  core architecture was triggered by a
  couple of factors.
 Transistor count is one of the reasons that
  drive the industry toward the dual core
  architecture.
 Instead of using the available
  astronomically high transistor counts to
  design a new, more complex

 single core processor that would offer
  higher performance than the present
  offerings.Chip makers have decided to put
  these transistors to use in producing two
  identical yet independent cores and
  combining them in to a single package.
 This is actually a far better use of the
  available transistors, and in return should
  give the consumers more value for their
  money.                                        5
WHAT IS DUAL CORE
PROCESSOR ?
A   dual core processor is a CPU with
  two separate cores on the same die,
  each with its own cache.
 It's the equivalent of getting two
  microprocessors in one.

REQUIREMENT OF DUAL
CORE PROCESSOR
In a single-core or traditional processor
the CPU is fed strings of instructions it
must order, execute, then selectively store
in its cache for quick retrieval.

 When data outside the cache is
required, it is retrieved through the system
bus from random access memory (RAM)
or from storage devices.

 Accessing these slows down performance
  to the maximum speed the bus, RAM or
  storage device will allow, which is far
  slower than the speed of the CPU.
 The situation is compounded when multi-
  tasking.
 In this case the processor must switch back
  and forth between two or more sets of data
  streams and programs. CPU resources are
  depleted and performance suffers.

    Intel's dual-core processor for
    dual processor (DP) servers
    and workstations, delivers a
    new level of energy-efficient
    performance from the
    innovative Intel Core
    microarchitecture,

 environments, 32-bit and 64-bit business-
  critical applications and high-end
  workstations.
 Combined with the Intel 5000 chipset
  family and Fully Buffered DIMM
  (FBDIMM) technology, the Dual-Core Intel
  Xeon processor 5100 series-based platforms
  are expected to deliver up to 3 times the
  performance and 3.5 times the
  performance/watt of previous-generation
  single-core Intel Xeon processors.

DISADVANTAGES
  Dual core processor face a disadvantages
If they both share one front side bus.
 Software needs to be redesigned to work
   specifically with dual core processors.
CONCLUSION
   Those individuals out there who already use software that is
    multithreaded will see the most benefit from the dual
    processors.
   Dual core processors are now available for purchase and
    they are quickly becoming the dominant architecture
     in the industry.
   Look forward to seeing more dual core desktop and laptop
    computers at the retail level ,as well as multi core processors
    coming soon.
    The price for dual core technology is a little more
    expensive, however most people that buy dual core
    technology feel that the power in processing is well worth
    the additional cost.                                        19
