Intel · Core i3 · 2011 · LGA1155
The Intel Core i3-2125 is a desktop processor with 2 cores, released in 2011 at an MSRP of $134. It is part of the Core i3 lineup, using the 2nd Gen platform, and fits the LGA1155 socket. Internally, it is built on the "Sandy Bridge" architecture. Thanks to Intel Hyper-Threading, each core can handle two instruction streams simultaneously, yielding a total of 4 threads for improved parallelism. It operates at a fixed 3.3 GHz. Intel manufactures the "Sandy Bridge" silicon on a 32nm process node. Its multiplier is locked, so any overclocking has to come from raising the base clock rather than the multiplier. This processor supports DDR3 memory. With a TDP of 65W, the Core i3-2125 is an efficient chip suitable for modest cooling solutions. Integrated graphics are provided by the HD 3000 solution, so a discrete GPU is not required for display output. The cache hierarchy consists of 32KB/core of L1, 0.5MB of L2, and 3MB of L3 cache.
Unusually ships with the full HD 3000 (GT2) iGPU — one of the very few Sandy Bridge i3 models to do so. Aimed at HTPC and media builds needing better integrated graphics.
