The Intel Core i7-3940XM was a mobile processor with 4 cores, launched in September 2012. It is part of the Core i7 Extreme lineup, using the Ivy Bridge architecture with Socket G2 (988B). Thanks to Intel Hyper-Threading the core-count is effectively doubled, to 8 threads. Core i7-3940XM has 8 MB of L3 cache and operates at 3 GHz by default, but can boost up to 3.9 GHz, depending on the workload. Intel is building the Core i7-3940XM on a 22 nm production process using 1,400 million transistors. You may freely adjust the unlocked multiplier on Core i7-3940XM, which simplifies overclocking greatly, as you can easily dial in any overclocking frequency.
With a TDP of 55 W, the Core i7-3940XM consumes typical power levels for a modern PC. Intel's processor supports DDR3 memory with a dual-channel interface. This processor features the Intel HD 4000 integrated graphics solution.
Hardware virtualization is available on the Core i7-3940XM, 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.
