Power Considerations
5.2
Power Consumption
The goal of this description is to provide a method to calculate the power consumption for the
CP6003-SA baseboard and for additional configurations. The processor and memory dissi-
pates the majority of the thermal power.
The power consumption tables below list the voltage and the power specifications for the
CP6003-SA 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. All measurements
were conducted at a temperature of 25°C. The measured values varied because the power
consumption 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 payload power consumption was measured using the following the 2
sors:
• Quad-core Intel® Core™ i7-2715QE (SV), 2.1 GHz, 6 MB L3 cache
• Dual-core Intel® Core™ i7-2655LE (LV), 2.2 GHz, 4 MB L3 cache
• Dual-core Intel® Core™ i5-2515E (SV), 2.5 GHz, 3 MB L3 cache
with the following firmware and under the following testing conditions:
• CP6003-SA in uEFI shell mode
For this measurement the processor cores were active (no power management enabled),
the graphics controller was in idle state (no application running) and Intel® Turbo Boost
Technology was enabled.
• CP6003-SA 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
(no application running) and Intel® Turbo Boost Technology was enabled.
• CP6003-SA with Windows® XP, 32-bit, maximum processor workload with basic graph-
ics operation
For this measurement all processor cores were operating at maximum workload and the
graphics controller was performing basic operation (e.g. dual screen output configuration
with no 3D graphics application running) while Intel® Turbo Boost Technology was dis-
abled. These values represent the power dissipation reached under realistic, OS-con-
trolled applications with the processor operating at maximum performance.
• CP6003-SA 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 the graphics controller. For this measurement
Intel® Turbo Boost Technology was enabled. These values are unlikely to be reached in
real applications.
The following tables indicate the typical power consumption of the CP6003-SA with 4 GB DDR3
SDRAM in dual-channel mode. The measurements were made with the CP6003-SA in uEFI
shell mode as well as with the Windows® XP operating system, 32-bit.
