Evo Notebook N1005 Series - CPU Subsystem Page

CPU Subsystem
The notebook provides support for the AMD Athlon with QuantiSpeed architecture.
 The Athlon processor uses Organic Pin Grid Array (OPGA) packaging, provides a 266MHz FSB, and is available in the following speeds:
  • 1.4GHz
  • 1.5GHz
  • 1.6GHz
  • 1.7GHz
  • 1.8GHz
Both processors support AMD's PowerNow! Technology. The Windows XP operating system also provides power management and allows you to view the CPU power scheme from the System Properties dialog box.
NOTE: QuantiSpeed Architecture
QuantiSpeed architecture allows the AMD Athlon XP processor to accomplish more instructions per clock cycle (IPC).
NOTE: Organic Pin Grid Array (OPGA)
OPGA packaging technology uses a fiberglass substrate, which provides better performance by lowering the impedance and cost of the package.
NOTE: PowerNow! Technology
AMD's PowerNow! technology extends the notebook's battery life by automatically adjusting the operating frequency and voltage of the processor according to the specific needs of each task. For example, a word processing application requires many fewer cycles than a photo editing program, and thus requires less power. The processor instantly responds to increased or decreased workloads.
NOTE: CPU Power Scheme
Windows XP defines four control policies for processor performance control: 
  • Constant - always runs at lowest performance state (optimized CPU speed)
  • Adaptive - performance state is chosen based on CPU demand (varies between maximum and optimized CPU speed) 
  • Degrade - starts at lowest performance state (optimized), then uses linear performance reduction (stop clock throttling) as the battery discharges 
  • None - always runs at highest performance state (maximum CPU speed)
