Product details
The Intel® Core™ i7-7740X is a high-end desktop (HEDT) processor from the “Kaby Lake-X” family, released in 2017. It was a unique and somewhat controversial release because it brought mainstream quad-core architecture to Intel’s enthusiast X299 platform.
Unlike the “Skylake-X” chips released alongside it, the i7-7740X is essentially a highly binned i7-7700K adapted for the LGA 2066 socket, stripped of integrated graphics to allow for better thermal headroom and overclocking.
