From what I have seen, I think many dual-core i5 CPUs for notebooks support hyperthreading.

The U (ultra-low power) lines are indeed two-core with Hyperthreading. All others are 4 core without.

Okay, that explains it. The only i5-based systems I have used (or still use) are notebooks.

This changed with 8th-gen Intel. The low-powers are now dual-HT/quad/quad-HT i3/i5/i7 [1]/[2]/[3]

Yes, you're right, I was thinking only about desktop CPUs, forgetting the laptop CPUs are different.
