'''Core i3-2312M''' is a [[dual-core]] entry-level performance mobile [[x86]] microprocessor introduced by [[Intel]] in mid-[[2011]]. Fabricated on a [[32 nm process]] based on the {{intel|Sandy Bridge|l=arch}} microarchitecture, this processor operates at 2.1 GHz with a [[TDP]] of 35 Watts. The i3-2312M supports up to 16 GiB of dual-channel DDR3-1333 memory and incorporates Intel's {{intel|HD Graphics 3000}} [[integrated graphics]] operating at 650 MHz with a burst frequency of 1.1 GHz.
This specific model is one of a handful of processors that could be upgraded into a more performant model through Intel's {{intel|Upgrade Service}}. Doing so would turn this "Core i3-2312M" into a "{{\\|i3-2393M|Core i3-2393M}}", increasing the [[cache]] and [[frequency]] for a modest performance gain.
