NOTES:
1. This spec is the Thermal Design Power and it is the estimated maximum possible expected power generated in
a component by a realistic application. It is based on extrapolations in both hardware and software technology
over the life of the component. It does not represent the expected power generated by a power virus. Studies
by Intel indicate that no application will cause thermally significant power dissipation exceeding this
specification, although it is possible to concoct higher power synthetic workloads that write but never read.
Under realistic read/write conditions, this higher power workload can only be transient, and is accounted in the
Icc (Max) spec.
2. Pre-silicon specs have a +20% / -10% tolerance.
3. These current levels can happen simultaneously, and can be summed into one supply.
