  > A CPU oldali big.LITTLE szvsz nem kamu.

  igen ..
  valami hasonló újdonság szerepel a programozó doksiban is.

  CPUID Fn8000_0026_EAX_n[N:0] Extended CPU Topology

  31 AsymmetricTopology
  Set to 1 if all components at the current hierarchy level do not report the
  same number of logical processors (NumLogProc).
  30 HeterogeneousCores
  Set to 1 if all components at the current hierarchy level do not consist of
  the cores that report the same core type (CoreType).
  29 EfficiencyRankingAvailable
  Set to 1 if processor power efficiency ranking (PwrEfficiencyRanking) is
  available and varies between cores. Only valid for LevelType = 1h (Core)

  31:28 CoreType
  Reports a value that may be used to distinguish between cores with
  different architectural and microarchitectural properties (for example,
  cores with different performance or power characteristics). Refer to the
  Processor Programming Reference Manual applicable to your product for
  a list of the available core types. Only valid for LevelType = 1h (Core).
  27:24 NativeModelID
  Reports a value that may be used to further differentiate implementation
  specific features. Native mode ID is used in conjunction with the family,
  model, and stepping identifiers. Refer to the Processor Programming
  Reference Manual applicable to your product for a list of Native Mode
  IDs. Only valid for LevelType = 1h (Core).
  23:16 PwrEfficiencyRanking
  Reports a static efficiency ranking between cores of a specific core type,
  where a lower value indicates comparatively lower power consumption
  and lower performance. Only valid for LevelType = 1h (Core).
  15:0 NumLogProc
  Number of logical processors at the current hierarchy level.
