microprocessors. Performance tests, such as SYSmark & MobileMark, are measured using specific computer systems, components, software, operations and functions. Any change to any of those factors may cause the results to vary. You should consult other
information & performance tests to assist you in fully evaluating your contemplated purchases, including the performance of that product when combined with other products. Benchmark Source: Intel Corporation - Optimization Notice: Intel’s compilers may or
may not optimize to the same degree for non-Intel microprocessors for optimizations that are not unique to Intel microprocessors. These optimizations include SSE2, SSE3, and SSSE3 instruction sets & other optimizations. Intel does not guarantee the
availability, functionality, or effectiveness of any optimization on microprocessors not manufactured by Intel. Microprocessor-dependent optimizations in this product are intended for use with Intel microprocessors. Certain optimizations not specific to Intel
microarchitecture are reserved for Intel microprocessors. Please refer to the applicable product User & Reference Guides for more information regarding the specific instruction sets covered by this notice. Notice revision #20110804 .

Actionable Wake-Up, Sleep State, Frequency & Temperature Data
Intel® Energy Profiler
 Consolidate wake-ups & save
energy by remaining in a lower
power state for longer periods
of time, leading to longer
battery life
 Optimize fan-less systems

Correctness Tools Increase ROI By 12%-21%1
 Errors found earlier are less expensive to fix
 Several studies, ROI% varies, but earlier is cheaper
Diagnosing Some Errors Can Take Months
 Races & deadlocks not easily reproduced
 Memory errors can be hard to find without a tool
Debugger Integration Speeds Diagnosis
 Breakpoint set just before the problem
 Examine variables & threads with the debugger
Find & Debug Memory & Threading Errors
Memory & Thread Debugger – Intel® Inspector
Debugger Breakpoints
Diagnose in hours instead of months
Intel® Inspector dramatically sped up
our ability to track down difficult to
isolate threading errors before our
packages are released to the field.
