5.2 Power Consumption
The goal of this description is to provide a method to calculate the power consumption for the
CP3002 baseboard and for additional configurations. The processor dissipates the majority of
the thermal power.
The power consumption tables below list the voltage and the power specifications for the
CP3002 board and its accessories. The values were measured using an 8-slot passive Com-
pactPCI backplane with two power supplies, one for the CPU, and the other for the hard disk
and the CompactPCI system fans.
The operating systems used were uEFI shell and Windows® XP, 32-bit. The Core™ i7 proces-
sors had Intel® Turbo Boost Technology and Intel® Intelligent Power Sharing enabled. All mea-
surements were conducted at a temperature of 25°C. The measured values varied, because
the power consumption was dependent on the processor activity.
The power consumption was measured using the following processors:
• Intel® Core™ i7-660UE (ULV), 1.33 GHz, 4 MB L3 cache
• Intel® Core™ i7-620LE (LV), 2.0 GHz, 4 MB L3 cache
• Intel® Core™ i7-610E (SV), 2.53 GHz, 4 MB L3 cache
• Intel® Celeron® U3405 (ULV), 1.07 GHz, 2 MB L3 cache
with the following firmware and under the following testing conditions:
• CP3002 in EFI shell
For this measurement the processor cores were active (no power management enabled)
and the graphics controller was in idle state (no application running).
• CP3002 with Windows® XP, 32-bit, processor and graphics controller in idle state
For this measurement all processor cores and the graphics controller were in idle state
(power management enabled and no application running).
• CP3002 with Windows® XP, 32-bit, maximum processor workload with graphics control-
ler in idle state
For this measurement all processor cores were operating at maximum workload and the
graphics controller was in idle state (e.g. dual screen output configuration with no video
application running). These values represent the power dissipation reached under real-
istic, OS-controlled applications with the processor operating at maximum performance.
• CP3002 with Win.® XP, 32-bit, maximum processor and graphics controller workload
These values represent the maximum power dissipation achieved through the use of
specific tools to heat up the processor and graphics controller. These values are unlikely
to be reached in real applications.
The following tables indicate the power consumption of the CP3002 with 4 GB DDR3 SDRAM
memory with ECC (one 2 GB SODIMM module with ECC in each DDR3 SODIMM socket). The
measurements were made with the CP3002 in EFI Shell mode as well as with the Windows®
XP operating system, 32-bit.
Note ...
The power consumption values indicated in the tables below can vary depend-
ing on the ambient temperature or the system performance. This can result in
deviations of the power consumption values of up to 10%.
