The i3-3120M is a dual-core processor that simulates two additional processing cores via Hyperthreading, which noticeably improves their utilization in a few applications. Intel omits a clock-increasing Turbo feature so that the CPU has a maximum of only 2.5 GHz available.
The CPU is a member of the lower performance categories in Cinebench. The comparatively good performance in the multi-thread test is due to Hyperthreading.
The modern architecture in a 22 nm structure width ensures low power
