The Intel Core i3-4100U is a mobile processor with 2 cores, launched in June 2013. It is part of the Core i3 lineup, using the Haswell architecture with BGA 1168. Thanks to Intel Hyper-Threading the core-count is effectively doubled, to 4 threads. Core i3-4100U has 3 MB of L3 cache and operates at 1800 MHz. Intel is making the Core i3-4100U on a 22 nm production node using 1,400 million transistors. The multiplier is locked on Core i3-4100U, which limits its overclocking potential.
With a TDP of 15 W, the Core i3-4100U consumes very little energy. Intel's processor supports DDR3 memory. This processor features the Intel HD 4400 integrated graphics solution.
Hardware virtualization is available on the Core i3-4100U, which greatly improves virtual machine performance. Additionally, IOMMU virtualization (PCI passthrough) is supported, so that guest virtual machines may directly use host hardware. Programs using Advanced Vector Extensions (AVX) can run on this processor, boosting performance for calculation-heavy applications.
