The technologies used by Intel for Atom Processor are:
High Performance Technology
-
Intel® Hyper-Threading Technology: Provides performance & support for multi threaded applications enabling increased performance and system responsiveness in multitasking environments by enabling the processor to execute two instruction threads in parallel.
-
Intel® Virtualization Technology: It is a set of hardware enhancements on the Intel® Atom processor series providing the flexibility to run dual operating systems and applications in independent partitions.
-
Intel® Digital Media Boost: Enhanced Performance on Floating Point intensive applications such as CAD tools, 3D & 2D modeling, Video Editing, Digital Music, Digital Photography & Gaming
-
Intel® Smart Cache: Smarter, more efficient cache & bus design thus offering even more efficient data sharing, providing enhanced performance, responsiveness and power savings.
-
Power Optimized Front Side Bus: 533MHz FSB provides increased data bandwidth as compared to prior generations (400MHz) for faster data transfer.
- Enhanced Data Prefetcher: Efficient speculation and loading into L2 cache of data likely to be requested by processor.
Low Power Capabilities
-
Enhanced Intel® SpeedStep® Technology: Allows for better match of performance to application demand.
-
Deep Power Down Technology with Dynamic Cache Sizing: Dynamic Cache Sizing saves power by turning off Cache ways that have had data saved in memory. This power saving feature enables 80-100mW idle power and 160-220mW average power for the processor.
-
Low Thermal Design Power: Lower thermal design power enables thinner, lighter MID devices as it reduces the cooling requirements.
-
Mobile Voltage Positioning: Dynamically lowers voltage based on processor activity to lower thermal design power.
-
Enhanced Deeper Sleep: Saves power by flushing cache data to system memory during periods of inactivity to lower CPU
