Intel Core i7-3770K

Intel 3770K

The Intel Core i7-3770K is the fastest LGA1155 processor for desktop PCs and is based on the Ivy Bridge architecture. Due to Hyperthreading, the four cores can handle up to eight threads in parallel, leading to better utilization of the CPU. Each core offers a base speed of 3.5 GHz, but can dynamically increase clock rates with Turbo Boost up to 3.7 GHz (for 4 active cores), 3.8 GHz (for 2 active cores) and 3.9 GHz (for 1 active core). Furthermore, the "K" series processors offers an unlocked multiplier for easy overclocking.

Ivy Bridge is an enhanced die shrink of the Sandy Bridge architecture with improvements on both GPU and CPU performance. The CPUs are produced in 22nm (versus 32nm Sandy Bridge CPUs) and are the first to introduce 3D transistors for increased energy efficiency when compared to similarly clocked Sandy Bridge processors. Other new features are integrated PCI Express 3.0 and  DDR3(L)-1600 support.

The performance of the Core i7-3770K is slightly above a similarly clocked Sandy Bridge processor due to slight architectural improvements. Therefore, the Core i7-2700K is outperformed by about 10 percent. Compared to AMD's fastest desktop CPU (FX-8350), the Core i7-3770K is significantly faster.

The integrated Intel HD Graphics 4000 GPU offers 16 Execution Units (EUs) clocked at 650 MHz up to 1150 MHz with Turbo Boost. In recent games, the performance is only sufficient for low resolutions and details.

The total power consumption of the CPU, graphics and memory controller is specified by Intel at 77 watts (TDP).
