Hello,
I’m puzzled by the report from lstopo about the number of physical cores on an
iMac with
I5-7500. It is specified by Intel as a quad core processor and lstopo reports
only 2 cores:
lstopo
<<
Machine (8192MB total) + NUMANode L#0 (P#0 8192MB) + L3 L#0 (6144KB)
Core L#0
L2 L#0 (256KB) + L1d L#0 (32KB) + L1i L#0 (32KB) + PU L#0 (P#0)
L2 L#1 (256KB) + L1d L#1 (32KB) + L1i L#1 (32KB) + PU L#1 (P#1)
Core L#1
L2 L#2 (256KB) + L1d L#2 (32KB) + L1i L#2 (32KB) + PU L#2 (P#2)
L2 L#3 (256KB) + L1d L#3 (32KB) + L1i L#3 (32KB) + PU L#3 (P#3)

When running system_profiler SPHardwareDataType
I obtain:
