4GHz, Four Cores
Expected later this month, the 4GHz Core i7-4790K contains 1.4 billion transistors and will be the first Intel processor to run all four cores at that speed. Made with Intel's 22nm process, the eight-thread chip is optimized for overclocking, can reach a maximum of speed of 4.4GHz in Intel's Turbo Boost 2.0 mode and supports two-channel DDR3 memory at 1,600MHz. Also inside is an Intel HD Graphics 4600 GPU running at 1,250MHz. With its latest processors, Intel claims a performance improvement of 291 percent over the Intel Core 2 Quad Q9650 CPU of five to six years ago.
