Symbol
This spec is the Thermal Design Power and 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. Tdie is measured at the top center of the package.
These current levels can happen simultaneously, and can be summed into one supply.
Estimate is only for max current coming through the chipset’s supply balls.
Rail includes PLL current.
Includes maximum leakage.
Calculated for highest future projected frequencies.
Iccmax is determined on a per-interface basis, and all cannot happen simultaneously.
Iccmax number includes max current for all signal names listed in the table.
May vary from CPU as this estimate does not include sense Amps, as they are on a separate rail, or signals
that are CPU specific.
