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 Sandy Bridge 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 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 Upgrade Service. Doing so would turn this "Core i3-2312M" into a "Core i3-2393M", increasing the cache and frequency for a modest performance gain.
Cache[edit]
- Main article: Sandy Bridge § Cache
![]() |
Cache Organization
Cache is a hardware component containing a relatively small and extremely fast memory designed to speed up the performance of a CPU by preparing ahead of time the data it needs to read from a relatively slower medium such as main memory. The organization and amount of cache can have a large impact on the performance, power consumption, die size, and consequently cost of the IC. Cache is specified by its size, number of sets, associativity, block size, sub-block size, and fetch and write-back policies. Note: All units are in kibibytes and mebibytes. |
