The Intel Core i5-2405S was a desktop processor with 4 cores, launched in May 2011. It is part of the Core i5 lineup, using the Sandy Bridge architecture with Socket 1155. Core i5-2405S has 6 MB of L3 cache and operates at 2.5 GHz by default, but can boost up to 3.3 GHz, depending on the workload. Intel is making the Core i5-2405S on a 32 nm production node using 1,160 million transistors. The multiplier is locked on Core i5-2405S, which limits its overclocking potential.
With a TDP of 65 W, the Core i5-2405S consumes typical power levels for a modern PC. Intel's processor supports DDR3 memory with a dual-channel interface. For communication with other components in the system, Core i5-2405S uses a PCI-Express Gen 3 connection. This processor features the Intel HD 3000 integrated graphics solution.
Hardware virtualization is available on the Core i5-2405S, which greatly improves virtual machine performance. Programs using Advanced Vector Extensions (AVX) can run on this processor, boosting performance for calculation-heavy applications.
