По http://www.intel.com/Assets/en_US/PDF/specupdate/313065.pdf это
либо Xeon 5060 (SL96A), либо 5063 (SL96B) - они, похоже, отличаются
только напряжением питания, что определить сложно (DMI обычно в этом
месте показывает чушь).

Нет, на самом деле процессор один, в котором 2 ядра (cpu cores: 2), но
с гипертредингом (siblings: 4).

Второй сокет есть (если DMI не врёт), но он пустой.
