We’ve mentioned before that Intel has no intentions of significantly ramping
up the clock speed of their Pentium 4 processor until the second half of this
year when they introduce the first 90nm Prescott core. The move to 90nm will
provide for smaller, faster and cooler running transistors that will enable
clock speeds of greater than 3.2GHz with relative ease (compared to on the current
130nm core), but until that time comes Intel is relying on improvements on the
platform side of things to keep performance competitive.

Today we’ve
seen the launch of Intel’s brand new flagship chipset — the 875P (previously
known as Canterwood); alongside the 875P, Intel is introducing their newest
flagship desktop processor — the Pentium 4 C. The C designates 800MHz FSB support,
much like the B designated 533MHz FSB support in the early days of the first
533MHz FSB Pentium 4 processors.

Eventually the C designation will fade away, but we’re stuck with it initially
in order to remove any confusion when customers see two identically clocked
processors with different FSB frequencies. You actually won’t have to deal with
that confusion for another several weeks, as the first and only 800MHz FSB Pentium
4 processor being released at this time doesn’t overlap in clock speed with
any other Pentium 4.

The first 800MHz FSB CPU from Intel is the Pentium 4 3.0C which, as you can
probably guess, runs at an even 3GHz — just 66MHz shy of the previous champ.
There will be other 800MHz FSB processors to come, both lower and higher clocked
than today’s 3.0C, but for now this is all Intel is introducing.

Other than 800MHz FSB support, these new C processors will feature Hyper Threading
(HT) and sell for a slight premium ($20 — $40) over other non-HT Pentium 4’s
courtesy of the improved performance provided by HT.

We’ve already provided quite a bit of information on the platform that Intel
is launching with the Pentium 4 3.0C, so be sure to read
our 875P review to get the details before continuing with this review.

Pentium 4 3GHz w/ 800MHz System Bus and Intel’s Canterwood

With the launch of Intel’s new «Canterwood»
chipset, we’re given a new Northbridge and a new Southbridge
to work with, along with all of the latest creature
comforts.  What, no passenger side airbag?


PAT —
Performance Acceleration Technology:

Intel has optimized the performance of the
Canterwood chipset’s memory controller and improved on
latency characteristics in two key areas, DRAM Chip Select
and Memory Controller Access.

There is a resultant 2 clock improvement for
Canterwood, which should help somewhat.  Intel is
calling this «PAT», Performance Acceleration Technology. 
Frankly this feels like a bit of Marketing spin.  We
should also note that for some reason, although we could set
2, 2, 2, 5 timings, for the PC3500 DDR Memory we used in
testing at 400MHz in other boards, we could not get beyond 
2, 3, 3, 5 timings with this new Intel D875PBZ board. 
It seems as though Intel’s new chipset is a little less
forgiving with respect to aggressive memory timings. 
However, we’re sure Memory OEMs will be targeting full
performance with this chipset, so it probably won’t be long
before better memory is available, that can support
aggressive timings like we’ve seen with the i845PE.

CSA — Communications Streaming
Architecture:

Both Canterwood and the upcoming Springdale
chipset share a new Networking technology from Intel called
«CSA».   CSA is essentially a direct link to the
Northbridge System Controller, versus utilizing the PCI bus. 
This allows Intel’s Pro/1000CT MAC/Phy controller direct
access to system memory, with higher overall bandwidth at
266MB/sec, twice that of PCI, as well as reduced CPU
utilization.  The benefits are obvious.

  • Direct Access to System Memory

  • Prioritized Access to GbE traffic

  • 1.5V Interface

  • Low Latency Design

  • 266 MB/s dedicated to Networking I/O

  • Reduced CPU Utilization

  • Better management of simultaneous data
    streams

  • Lower GbE component power

  • Bursts of network traffic handled with
    ease

We had a relatively short window of time to
test this new Intel platform and as a result, we’re not able
to provide you back-up factual analysis to support these
claims.   However, we can report that during testing and
routine use on a 100Mb Ethernet Network, the Pro/1000CT
Controller performed admirably with excellent throughput and
reliability.

Intel’s
Pentium 4 3GHz With 800MHz System Bus
And The i875P «Canterwood» Chipset
More
bandwidth and leading edge desktop technology for the P4

Time certainly does fly when you
are clipping along at 3GHz, doesn’t it?  It has been a
whole 5 months since
Intel
released their last processor speed bump.  Intel
actually let this one ride a little bit it seems.  In
early February, AMD let loose with their new «Barton» core
based

Athlon XP 3000+ (2. 166GHz), in an effort to keep pace
with Intel’s brute force approach to processing.  Don’t
misunderstand us, there certainly is nothing wrong with
«brute force», when it comes to computing.  However,
efficiency is also the name of the game and while it is
impressive to see a 3GHz CPU like the Pentium 4, in mass
production, it’s equally as impressive to see a processor
like the AMD Barton core, keep step with the P4, while
clocked almost 1GHz lower.  The Pentium 4’s super deep
«hyper pipelined» architecture, that allows it to hit such
impressive clock speeds, is also a source of some
inefficiency within the chip.  It seems you can’t
really have your cake and eat it too, because along with
this architecture comes the inherent latency associated with
a deeper pipeline.  Regardless, like all things in
life, there is a balance; a balance between raw clock speed
and processing efficiency.  Intel certainly seems to
have found that balance and like AMD, they are on a
never-ending quest to improve upon the existing
architecture.

Another way to enhance P4
performance, is by providing the CPU with more bandwidth via
associated bus interfaces.  Simply cranking up CPU
clock cycles, will certainly bring you incremental
performance.  However, giving the processor enough
bandwidth to get out to other system resources and
peripherals, is also critical for overall throughput. 
Otherwise you’ll have the equivalent of a jet fueled Funny
Car, sitting in neutral, red-lining the engine and going
nowhere fast.  As such, we’ve witnessed both Intel and
AMD taking System Bus (or Front Side Bus) speeds up a notch
or two, along the way of their respective roadmaps.  At
2.26 and 2.4GHz, Intel took the Pentium 4 to a 533MHz System
Bus, with a Quad Pumped 133MHz reference clock.  This
time around, at 3GHz, Intel gives us an 800MHz System Bus,
with a Quad Pumped 200MHz reference clock.  However, we
are reminded once again, of a lesson taught to us by our
Asian friends, that of «yin and yang», or balance.  To
compliment this extra bus bandwidth Intel also brought forth
Dual Channel DDR400 memory support.  

If this is beginning to sound
like a complete system controller overhaul, you would be
correct.  Along with this new 800MHz System Bus capable
P4, comes Intel’s i875P chipset, more commonly referred to
as «Canterwood».  And while they were at it, Intel
brought many of the peripheral interfaces of their new
chipset, up to snuff as well.  The following is a
HotHardware.Com overview and performance analysis, of
Intel’s new Processor and Desktop Platform, based on their
new Pentium 4 3GHz with an 800MHz System Bus and the D875PBZ
— i875P driven motherboard.

  • 800MHz «Quad Pumped» Front Side Bus
  • Hyperthreading Technology for increased performance

  • . 13 micron manufacturing process
  • 512K on chip, Full Speed L2 Cache

  • 128bit Floating Point/Multimedia unit
  • «Hyper Pipelined» Technology for extremely high
    clock speeds
  • Intel «NetBurst» micro-architecture
  • Supported by the Intel® i875P and i865G chipsets,
    with Hyperthreading support
  • Internet Streaming SIMD Extensions 2
  • Intel® MMX? media enhancement technology
  • Memory cacheability up to 4 GB of addressable memory
    space and system memory scalability up to 64 GB of
    physical memory
  • Support for uni-processor designs
  • 1.525V operating voltage range

Obviously this quick specification list is a
repeat for the most part, with one exception.  Intel’s
new 3GHz Pentium (note the even 3GHz number, rather than
3.06GHz), is now characterized to run on an 800MHz System
Bus with a Quad Pumped 200MHz reference clock and DDR400
Memory Bus.   Who would have thought we would see an FSB
of 200MHz as a «stock» clock speed on any motherboard? 
Ahhh, but technology does roll on, doesn’t it?  This
one enhancement alone should boost performance nicely,
especially in system bandwidth demanding applications.

, according to our tests.

The performance of 4 cores, if any, and performance per core has the greatest impact on the result, since most games do not fully use more than 4 cores.

The speed of caches and working with RAM is also important.

Speed ​​in office use

Performance in everyday work such as browsers and office applications.

The performance of 1 core has the greatest impact on the result, since most of these applications use only one, ignoring the rest.

Similarly, many professional applications such as various CAD programs ignore multi-threaded performance.

Speed ​​in heavy applications

Performance in resource-intensive tasks loading a maximum of 8 cores.

The performance of all cores and their number has the greatest impact on the result, since most of these applications willingly use all the cores and increase the speed accordingly.

At the same time, certain periods of work can be demanding on the performance of one or two cores, for example, applying filters in the editor.

Data obtained from tests by users who tested their systems with and without overclocking. Thus, you see the average values ​​corresponding to the processor.

Different tasks require different CPU strengths. A system with few fast cores and low memory latency will be fine for the vast majority of games, but will be inferior to a system with a lot of slow cores in a rendering scenario.

We believe that a minimum 4/4 (4 physical cores and 4 threads) processor is suitable for a budget gaming PC. At the same time, some games can load it at 100%, slow down and freeze, and performing any tasks in the background will lead to a drop in FPS.

Ideally, the budget shopper should aim for a minimum of 4/8 and 6/6. A gamer with a big budget can choose between 6/12, 8/8 and 8/16. Processors with 10 and 12 cores can perform well in games with high frequency and fast memory, but are overkill for such tasks. Also, buying for the future is a dubious undertaking, since in a few years many slow cores may not provide sufficient gaming performance.

When choosing a processor for your work, consider how many cores your programs use. For example, photo and video editors can use 1-2 cores when working with filtering, and rendering or converting in the same editors already uses all threads.

Data obtained from tests by users who tested their systems both with overclocking (maximum value in the table) and without (minimum). A typical result is shown in the middle, the more filled in the color bar, the better the average result among all tested systems.
