Next-Generation Intel® Microarchitecture
- The i7 Has Landed |
 |
|
A new day, a new dawn and a new era in
the life of Intel bringing to the fore a
whole new concept of computing. When a
product of this nature and magnitude
comes along it most certainly has us
standing up and paying great attention
to what it can bring to the end users
within the professional community. There
have been many rumours of what the i7
can do and cannot do. What it cannot do,
we have not been able to find it as
every which way we turned it showed us
differently.
With a first outing of this magnitude it
means that something special should
grace the new set-up. Notwithstanding,
this is a double first outing as we see
today the exclusive first look at ATI's
FirePro V8700 professional graphics
card. Therefore this is an article which
is going to have many of you out there
reeling at the power of both the i7 with
its supporting X58 chipset mainboard and
the ferocious influence the ATI FirePro
V8700 has to offer.
This
enthusiast motherboard houses the X58
chipset, supporting three DDR3 channels,
LGA1366 socket and ICH10 Southbridge
which has been code-named Smackover. Its
packaged in an ATX form factor desktop
board based on the Intel X58 Express
chipset, 6 SATA (3.0Gb/s) ports storage
capability, 1 PCI, 3 PCI Express* x16, 1
PCI Express x1 IEEE-1394a, Gigabit LAN,
2 eSATA ports, Intel High Definition
Audio supporting 8-channel Dolby*
surround sound. |

If you pop
in a fourth module and occupy all the
slots the DX58SO motherboard won't be
running in quad-channel. It does default
back down to single channel mode, which
in turn has an impact memory bandwidth.
Therefore run with triple channel set-up
when possible. The official support
memory clock speed is 1066MHz, but times
have changed and 1333MHz, 1600MHz and
even 2000MHz memory kits will work on
the platform. But make sure you have the
correct supporting CPU. There are plenty
of supplying these new timing triple
kits. Some are at a great premium.
Plenty of features to behold. Delve into
the bios and its an overclockers heaven.
There are so many variables one could
spend all day covering this, though with
the help of other websites who have
pushed forward the board to day you can
read all about that later in your own
time. For now and today, we have to run
at the stock values as these are the
basic requirements of some of the tests
completed within.
Firstly as its Intel's day we look at a
few of the primary features that Nehalem
has to offer (kind thanks to Intel's
Public Relations here). |
|
Intel's
next-generation microarchitecture
(codenamed "Nehalem") represents the
next step in processor energy
efficiency, performance, and dynamic
scalability. Designed from the ground up
to take advantage of hafnium-based
Intel® 45nm hi-k metal gate silicon
technology, Nehalem will also be the
first to introduce Intel® QuickPath
technology.
Now
performance really does come "on-demand" |
|
• Dynamic
scalability, managed cores, threads,
cache, interfaces, and power for
energy-efficient performance on
demand.
• Design and performance scalability for
server, workstation, PC, and mobile
demands with support for 2-8+ cores
and up to 16+ threads with simultaneous multi-threading (SMT), and
scalable cache sizes, system
interconnects,
and integrated memory controllers.
• Simultaneous multi-threading brings
high-performance applications into
mainstream computing with 1-16+ threads
optimized for a new generation multi-core processor architecture.
• Scalable shared memory of Intel
QuickPath technology features memory
distributed to each processor with
integrated memory controllers and high-speed point-to-point interconnects
to unleash the performance of next-
generation Intel® multi-core processors.
• Multi-level shared cache improves
performance and efficiency by reducing
latency to frequently used data. |

Intel®
QuickPath Technology
Unleashing performance with interconnect
system architecture
Providing point-to-point high-speed
links to distributed shared memory,
Intel® QuickPath technology unleashes
the parallel processing performance of
next-generation Intel® 45nm
microarchitectures (codenamed Nehalem
and Tukwila). These microarchitectures,
built from the ground up, will be the
first to use the Intel QuickPath
interconnect system and can see
significant improvements in overall
performance.
With new Intel QuickPath technology
built into future Nehalem and Tukwila
microarchitectures, each processor core
will feature an integrated memory
controller and high-speed interconnect,
linking processors and other components
to deliver:
• Dynamically scalable interconnect
bandwidth designed to set loose the full
performance of Nehalem, Tukwila, and
future generations of Intel® multi-core processors
• Outstanding memory performance and
flexibility to support leading memory
technologies
• Tightly integrated interconnect
reliability, availability, and
serviceability (RAS) with
design-scalable configurations
for optimal balance of price, performance, and energy efficiency |

Therefore
what does this translate into real terms
that many will be trying to fathom out.
• The Front Side Bus is replaced by a
QuickPath interface. This means that
motherboards must use a chipset that
supports QuickPath.
• The memory controller is on the
processor, not in a separate chip, so
the memory is directly connected to the
processor.
• The memory controller supports three
channels of memory, and each channel can
support one or two DDR3
Dimms. This means that motherboards for the Core i7 have three or six
DIMM slots instead of two or four, and
that
Dimms should be installed in sets of three, not two.
• Intel® Core i7 is a single-die device:
all four cores, the memory controller,
and all cache are on a single die.
• Intel® Core i7 cores re-implement
Hyper-threading. Each of the four cores
can process two threads
simultaneously, so the processor appears to the Operating System as eight
CPUs. |
