The Intel Core i5-2405S is part of the second generation Intel Core i series processor line up. It is a quad core processor with Intel's turbo boost feature (up to 3.3GHz). The i5-2405S has a higher retail price yet lower frequency; this is because it has a lower power input and a lower thermal output (less heat) than several other models in the Core i5 line. Another reason for the higher price is the integrated HD Graphics 3000 on-die GPU. It is faster than the 2000 model featured on other models. Other advanced functions include virtualization, Idle states, Speed step, AES instructions, and Intel Fast Memory Access. The Intel Core i5-2405S is a good option for desktop builders who are looking for a high performance yet energy efficient qua core processor.
