Power Consumption

The goal of this description is to provide a method to calculate the power consumption for the
CP3002-RC/CP3002-RA baseboard and for additional configurations. The processor dissi-
pates the majority of the thermal power.
The power consumption tables below list the voltage and the power specifications for the
CP3002-RC/CP3002-RA board and its accessories. The values were measured using an 8-slot
passive CompactPCI backplane with two power supplies, one for the CPU, and the other for
the hard disk.
The operating systems used were uEFI shell and Windows® XP, 32-bit, with Intel® Turbo
Boost Technology and Intel® Intelligent Power Sharing enabled. All measurements were con-
ducted at a temperature of 25°C. The measured values varied, because the power consump-
tion was dependent on the processor activity.
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%.
The power consumption was measured using the following processor:
• Intel® Core™ i7-620LE (LV) processor with ECC, 2.0 GHz, 4 MB L3 cache
with the following firmware and under the following testing conditions:
• CP3002-RC/CP3002-RA 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-RC/CP3002-RA 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-RC/CP3002-RA with Win.® XP, 32-bit, typical processor and graphics controller
workload
For this measurement all processor cores and the graphics controller were operating at
a typical workload. These values represent the power dissipation reached under realistic,
OS-controlled applications with the processor operating at typical performance.
• CP3002-RC/CP3002-RA with Win.® XP, 32-bit, maximum processor and graphics con-
troller 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-RC/CP3002-RA with 4 GB
DDR3 SDRAM in dual-channel mode. The measurements were made with the CP3002-RC/
CP3002-RA in EFI Shell mode as well as with the Windows® XP operating system, 32-bit.
