The Intel Core i5-2540M was a mobile processor with 2 cores, launched in February 2011. It is part of the Core i5 lineup, using the Sandy Bridge architecture with Socket G2 (988B). Thanks to Intel Hyper-Threading the core-count is effectively doubled, to 4 threads. Core i5-2540M has 3 MB of L3 cache and operates at 2.6 GHz. Intel is building the Core i5-2540M on a 32 nm production process using 624 million transistors. The multiplier is locked on Core i5-2540M, which limits its overclocking capabilities.
With a TDP of 35 W, the Core i5-2540M consumes only little energy. Intel's processor supports DDR3 memory with a dual-channel interface. This processor features the Intel HD 3000 integrated graphics solution.
Hardware virtualization is available on the Core i5-2540M, 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) will run on this processor, boosting performance for calculation-heavy applications.
