Intel's® chipset future
looks brighter than ever
With the introduction of both the Alderwood
and Grantsdale chipsets expected
in Q2 of this 2004, Intel® seems to be fulfilling it's promises of
increased performance and stunning
new technology. Continuing it's tradition of releasing high-end,
mainstream, and cost-sensitive chipsets, they will be releasing the
Alderwood chipset to meet the demands of the high-end market, the
Grantsdale-P and G are aimed at the mainstream market and the
Grantsdale GV and GL are taking care of the cost-sensitive market.
Alderwood
(Northbridge)
Intel's® Alderwood chipset comes as
the successor of the i875P Canterwood Chipset. The i875 chipset was
wildly popular due to it's support of all the latest technologies,
800MHz. FSB, Hyper-Threading, Dual-Channel memory support, and PAT
(Performance Acceleration Technology) which boosted the performance
level above anything attainable by the i865PE chipset.
The Alderwood (i925x) chipset is here
to continue the tradition of Intel "one-upping"
themselves. Like the i875 chipset, the new i925x chipset supports
800MHz. FSB, however it does it in a new format. The Alderwood is
using a LGA-775 socket to do so. LGA-775 (Land Grid Array) is the
latest technology which is being introduced along with the
Grantsdale and Alderwood chipsets and will be on all upcoming
Prescott motherboards. The innovations continue as Intel has chosen
to utilize Dual Channel ECC DDR-II on this motherboard. This
effectively doubles the bandwidth of the memory on the system and
will eliminate bottlenecks that are normally seen on current DDR
motherboards.

Although many
boards will see an increase in latency due to the usage of DDR-II,
the Alderwood has a re-worked bus which will help to eliminate this
phenomenon. For video support, Intel® has eliminated the AGP
bus and advanced to PCI-Express x16 for this chipset. PCI-Express
x16 sets the standard for video performance allowing 4GB/sec
bi-directional (8GB/sec total)! Since Alderwood is a high
performance version of the Grantsdale chipset, using onboard
graphics is not an option, discreet graphics are required, and with
the performance of this board, anything less would be cruel and
inhumane punishment. This chipset has been designed from the ground
up as the premier chipset to support the Intel® Pentium 4 Extreme
Edition.

Grantsdale-P and G
(Northbridge)
Intel® is far from neglecting the
mainstream market with it's soon to be introduced chipsets. The
Grantsdale-P (i915P) and the Grantsdale-G (i915G) chipsets differ
only slightly as the G has integrated graphics, and the P does not,
but besides that they are basically identical. Both chipsets support
the 800MHz. FSB with Hyper-Threading while utilizing the LGA-775
socket type. Dual DDR-II is also supported with the new chipset,
although it is standard DDR-II and not ECC capable. The Grantsdale-P
has PCI-Express x16 support for the latest and greatest graphics
cards such as the ATI R400 and the NVIDIA NV40, while the
Grantsdale-G will allow for PCI Express x16 and also uses integrated
Intel Extreme Graphics 3. The combination on the Grantsdale-G will
allow for multiple monitor configuration. Although on-board graphics
are generally scoffed at by power users, the Intel® Extreme
Graphics 3 will include Pixel Shader 2.0 which will allow it to
fully support the new GUI interface of Microsoft's forthcoming
operating system codenamed "Longhorn".

ICH6 / ICH6-R /
ICH6-W (Southbridge)
With all of the new Northbridge
chipsets arriving, Intel® has also worked hard to bring it's
Southbridge partner up to speed. Intel has not one, but 3 new
Southbridge chipsets to satisfy your every need. The most basics of
the three chipsets is the ICH6. The ICH6 includes support for 4
Serial ATA ports and 1 single UltraATA/100 channel. The ICH6 has
support for 4 PCI Express x1interfaces as well as continuing to
support PCI.
The ICH6-R is the follow on to the
ICH5-R chipset which was the RAID version of the previous
Southbridge unit. The difference in the new chipset is that they
have added more RAID modes, now RAID 0, 1, and 0+1 are all
supported, thanks to a doubling of the previously available Serial
ATA ports.
With the addition of the ICH6-W, you
gain the benefit of built in wireless connectivity. Tri-band support
is fully implemented with 802.11 a/b/g all available to the user.
All
of the ICH6 chipsets will feature Intel® High Definition Audio
(previously known as Azalia) which is the replacement for the AC'97
motherboard audio specification that we've all become familiar with
over the years. This is much more than a mere sound chip though as
it is designed to be an interface for virtually all media codecs on
the system, from audio to DVD, Intel's® new specification is going
to handle them all. With sound said to rival Creative Lab's Audigy2
card, Intel may end up upsetting audio vendors when customers who
would normally invest in external devices end up satisfied with the
quality and flexibility of their onboard audio.
- 4 SATA Ports
- 1 Channel UltraATA/100
- 4 PCI Express x1

- Intel "Matrix RAID" =
RAID 0, 1 (ICH6-R only)

Grantsdale-GV and GL
Looking further into the future, in
Q3 of 2004, Intel® will be introducing the cost-sensitive chipsets
based on the Grantsdale core. The Intel® Grantsdale-GV (i915GV)
will essentially have the same features as the Grantsdale-G chipset,
but with one major exception. The Intel Extreme Graphics 3 on the
motherboard will be the only graphics available. Unlike the
Grantsdale-G there will be no option to use external PCI Express x16
graphics.
The Intel® Grantsdale-GL (i915-GL)
motherboard will be almost identical to the Grantsdale-GV, with the
exception of CPU support. The Grantsdale-GL is designed for use with
the Intel® Celeron processor with the Prescott core and a 533MHz.
FSB. Budget-minded users would be wise to look to this board for
their basic system needs, with the Celeron processor and the value
chipset, this should make a very attractive price-point possible.
- LGA-775 "Socket T"
- 800MHz. FSB (533MHz FSB for the
Grantsdale-GL)
- Hyper-Threading
- ECC DDR-II
