Intel EIST SpeedStep — Phoronix
Written by Michael Larabel in Processors on 16 February 2006. Page 1 of 5. Add A Comment
Nearly seven years ago at the Intel Developer Forum in Palm Springs
California, Intel had first demonstrated Geyserville Technology. This dual-speed
technology, when paired with a 0.18-micron mobile Pentium processor, had offered
a distinct advantage as it was able to run in two processing modes — maximum performance
and battery optimized. Geyserville Technology allowed the processor to run slower
and decrease the voltage when the mobile solution was running off of a battery
(in order to reduce power consumption and allow robust performance without
sacrificing battery life), but when the laptop was then plugged into an AC outlet,
the frequency would return to normal. With the introduction of the Intel Mobile
Pentium 3 processors, the dual-speed Geyserville was renamed to SpeedStep Technology.
Shipping at that time were all sub-1GHz laptops yet SpeedStep/Geyserville proved
to be quite a valuable asset to Intel. Since the Geyserville inception, many
of Intel’s desktop and mobile processing technologies have changed or been
eliminated from the Coppermine 180nm process to Katmai 3D, but what has remained,
however, is Intel’s SpeedStep Technology. During this time SpeedStep
has been revitalized with the ability to have multiple power-states
as well as the changing the frequency depending
upon the computing power needed rather than strictly the power source. This technology can continue to be found in processors from their mobile
Pentium M and Core Duo parts to the desktop Pentium 4’s (600 series) and Pentium
D (excluding 820) CPUs under the name EIST, or rather Enhanced Intel SpeedStep Technology.
Another power innovation on the next-generation Core
Duo processors is Intel Dynamic Power Coordination and Enhanced Intel Deeper
Sleep.
These technologies allow dynamic cache sizing and only sending
power to the specific areas of the processor that it actually needs to compute
a specific operation. The only system requirements for SpeedStep are a supportive
Intel CPU, Chipset, BIOS, and operating system. Enhanced Intel SpeedStep Technology,
the updated technology found in the Pentium 4/D/M processors, are not Chipset
dependent as EIST voltage/frequency selection is software controlled by writing
to the processor MSR’s (Model Specific Registers). While SpeedStep is compatible
with operating systems going back to Microsoft Windows 95, Linux users have
been able to benefit from the technology when using the Linux 2.6 kernel
and cpufreq module. This vast operating system support without the need
for a special software configuration was due to SpeedStep originally being controlled
by toggling the GHI# pin. Intel’s direct competition to SpeedStep Technology
is AMD’s Cool ‘n’ Quiet, which is a fork of their original PowerNow
design.
Similar to as we had done last week when publishing our AMD Cool ‘n’
Quiet Linux investigation, we are back today with our findings from our most
recent SpeedStep investigation using an Intel Pentium M processor and the Linux
2.6.15 kernel with Fedora Core 4. For reference, below is the notebook computer
we had used throughout the testing process of this article as well as the prominent
software versions.
| Intel Pentium M 750 (1.86GHz) |
| IBM R52 18494WU (i915PM + ICH-6M) |
| 2 x 1024MB OCZ DDR2-533 |
| ATI RADEON X300 64MB (dedicated) |
| Toshiba Slim MK1032GAX |
| Fedora Core 4 |
| 2.6.15-1.1831_FC4 (i686) |
| 4.0.0 |
| ATI v8.22.5 |
| 6.8.2 |
Unlike our AMD Cool ‘n’ Quiet tests where we were forced to monitor
the CPU heatsink temperature, due to the lack of LM_Sensors v2.
9.2 detection on both the ASRock 939Dual-SATA2
and Tyan Tomcat K8E-SLI, with our SpeedStep testing we are relying heavily upon
some of the integrated IBM/Lenovo ThinkPad features. The CPU temperature was
monitored through the ThinkPad ACPI system temperature sensors. In addition,
we monitored the power consumption when the notebook was running off its battery
and then again when it was connected to a power outlet. We monitored the present
Wattage rate when the system was running off a battery using the ACPI battery
state, and the Seasonic PowerAngel to monitor the AC adapter Wattage. We dealt
with both the battery and AC power tests, due to the system being designed for
optimal performance (in both Linux and the IBM BIOS) when connected to an outlet,
while additional power management items are enabled when running off the battery.
Even though ATI’s v8.22.5 drivers support PowerPlay, which is similar
to SpeedStep except on the graphics front, we had ran the Mobility X300 64MB
at its standard operating frequencies throughout the entire process.
Similar
to our Cool ‘n’ Quiet piece, we had also performed some compilation benchmarks
to gather its effects on system performance. During the complete testing process,
the ambient room temperature was properly maintained as well as all other constants
and standard Phoronix testing practices. In addition, no external laptop coolers
were used during the testing process. Before moving onto the tests, on the following
pages are a few notes regarding cpufreq and Intel’s SpeedStep as well as information
pertaining to IBM ACPI features.

What is Pentium 4?
Pentium 4 refers to a series of single-core CPUs. The manufacturer of Pentium 4 is Intel. Pentium 4 has an easy operation on desktops, laptops, and entry-level servers.
The Pentium 4 processors were in circulation from 20 November 2000 till 8 August 2008. The architecture of Pentium 4 is NetBurst microarchitecture.
The predecessor of Pentium 4 is Pentium III and the successor of Pentium 4 is Pentium d. The introduction of Pentium 4 had mixed responses from the audience.
There was a dislike among developers for Pentium 4 because it posed a new set of code optimization rules. As expected, however, the new Pentium 4 outperformed the Pentium III in various aspects.
The processors of Pentium 4 consist of an integrated heat spreader.
The heat spreader ensures that there are no significant damages when mounting and unmounting cooling solutions. The bus speed of Pentium 4 is 533 MHz.
The processor base frequency is 2.80 GHz. In addition, there is no provision of an FSB parity. The Pentium d processor allows for the provision of running multi-threaded applications.
The double core model is ideal for the operation of both the client and server processes.
The VID voltage range of Pentium 4 is 1.340V-1.545V. The TDP is 68.4W. The package size of the processor is 35mm*35mm.
However, Pentium 4 doesn’t have turbo boost technology, hyper threading technology, virtualization technology, idle states, and enhanced intel speedset technology. Thus, there are some advantages and disadvantages to the processor.
What is Pentium d?
Pentium d refers to a series of double-core CPUs. The Pentium d processor came into being on 25 May 2005. However, Pentium d was discontinued on 8 August 2008.
The manufacturer of Pentium d is Intel.
The architecture of Pentium d is NetBurst microarchitecture. There are several practical applications of this model of Intel.
The Pentium d processor allows for the provision of running multi-threaded applications. The double core model is ideal for the operation of both the client and server processes.
In addition, pentium d provides services like transcoding of video and audio, photo and video editing, ray tracing, and rendering.
The processor base frequency of Pentium d is 3.40 GHz. The bus speed of Pentium d is 800 MHz. The TDP of Pentium d is 95W. The package size of Pentium d is 37.5mm*37.5mm.
In addition, it offers an idle states provision as well as Enhanced Intel SpeedStep Technology. Thus, there are a multitude of advantages offered.
Since Pentium d has a double core processor, it consumes a significantly large amount of energy. As a consequence, the Pentium d has a high heat generation which adversely impacts its functioning.
The heat generation, therefore, necessitates the installation of a third party cooling system to prevent any major damages.
Main Differences Between Pentium 4 and Pentium d
- Pentium 4 refers to a series of single-core CPUs. In contrast, Pentium d refers to a series of double-core CPUs.
- Pentium 4 has less power requirements. On the other hand, Pentium d consumes a significantly large amount of energy.

Intel D 840 Dual Core CPU
0
1.
Introduction
In our last review concerning Intel’s CPUs, we had tested the flagship Single-core processor from Intel, the 3.73GHz Extreme Edition which was also extremely expensive. This time, we have in our hands the 840 which is a Dual-Core CPU, running at 3.20GHz with 1MB L2 cache. Dual-Core processors are the new generation of CPUs and both Intel and AMD have already released not one, but over three different models.
The one we will review here costs approximately half the money of the P4 3.73GHz Extreme Edition and it is rather interesting to compare their performance. When you are about to get a new processor, most times, money will define which one is the most appropriate for your needs, otherwise we would all purchase the most expensive, thinking that we have also got the best. Is this true however?
| Architecture | 90 nm technology |
| L2 Cache | 2x1MB |
| Clock Speed | 3. 20 GHz |
| Front Side Bus | 800 MHz |
| Chipset | — Intel 955X Express chipset — Intel 945P Express chipset — Intel 945G Express chipset — Intel E7230 Chipset |
| Socket | LGA775 |
| Retail Package |
- Dual-Core: Provides two execution cores in one physical processor allowing the platform to
do more in less time while enjoying smooth interaction with your PC. - Enhanced Intel® SpeedStep® Technology: Available with
the 840 and 830 processors, Enhanced Intel Speedstep
Technology allows the system to dynamically adjust processor
voltage and core frequency, which can result in decreased
average power consumption and decreased average heat
production.
By decreasing power and heat on Desktop PCs,
system builders can (depending on system configurations)
potentially lower acoustics, and even develop more innovative
small form factor designs. Additionally, this feature may help
address power concerns in companies with sites approaching
the limits of bounded electrical infrastructures. Combined with
existing power saving features, Enhanced Intel SpeedStep
technology may provide an excellent balance between providing
power when you need it and conserving it when you don’t. - Execute Disable Bit: This feature, combined with a
supported operating system, allows memory to be marked
as executable or non-executable. If code attempts to run in
non-executable memory the processor raises an error to the
operating system. - Intel® Extended Memory 64 Technology: Intel EM64T provides an enhancement to
Intel’s 32-bit architecture by enabling the desktop processor
platform to access larger amounts of memory.
With appropriate
64-bit supporting hardware and software, platforms
based on an Intel processor supporting Intel EM64T can enable
use of extended virtual and physical memory. - 90nm Process Technology: The 90nm process
technology is the latest in Intel manufacturing and
technology leadership allowing for next generation
transistor advantages, such as strained silicon lattice to
deliver faster transistors and potentially increased performance. - Level 1 Cache: The Pentium D processor features two
16KB data caches. In addition to the data cache, each core
includes an Execution Trace Cache that stores up to 12 K
decoded micro-ops in the order of program execution. This
can increase performance by removing the decoder from the
main execution loop and makes more efficient usage of the
cache storage space since instructions that are branched
around are not stored.
- 2MB Level 2 Cache: The Intel Pentium D processor
based upon Intel 90nm process technology has a 1MB L2
Advanced Transfer Cache for each core (2MB total) improving
overall system performance by allowing each processor core
to have faster access to larger amounts of the most often
used data. - Streaming SIMD Extensions 3 (SSE3): Single Instruction
Multiple Data Extensions significantly accelerates performance
of digital media applications and includes additional
integer and cache ability instructions that may improve other
aspects of performance.

Processor Features & Definitions |
|
| Architecture |
Basic design of a microprocessor. |
| Cache
(MB/KB) |
A temporary storage area for frequently accessed or recently accessed data. Having certain data stored in a cache speeds up the operation of the computer. Cache size is measured in megabytes (MB) or kilobytes (KB). |
| Clock Speed
(GHz/MHz) |
Speed of the processor’s internal clock, which dictates how fast the processor can process data. Clock speed is usually measured in GHz (gigahertz, or billions of pulses per second). |
| Front Side Bus
(GHz/MHz) |
The connecting path between the processor and other key components such as the memory controller hub. FSB speed is measured in GHz or MHz. |
May include process technology and/or other architectural enhancements.The stock cooler that Intel includes in its retail version for the D 840 resembles the one used for the P4 series of processors.
If you look more carefully however, you’ll notice that there are some distinctive differences. The copper base, which exists in all of Intel’s stock coolers, is more voluminous. The fins are also of a different design. This indicates that the heat dissipation required is going to be much greater than in single-core processors. This is something we will check on later.
