general information

Intel Core i7-5820K Haswell-E 6-Core Desktop Processor

Punch up the power in everything you do with the Intel Core i7-5820K Desktop Processor. It delivers significant improvement in performance over previous generation processors, resulting in great system performance and responsiveness, strong security, and exceptional virtualization capability.

general information

No-holds-barred Processor Capabilities

The 5th Gen Intel Core i7-5820K Haswell-E processor gives you the performance you need to create and think out of the box. It has up to six cores, and features a dedicated 6 x 256KB KB L2 cache. It runs at a base frequency of 3.3GHz, and can be accelerated to 3.6 GHz, thanks to Intel Turbo Boost Technology 2.0. Intel Hyper-Threading Technology uses resources efficiently, enabling multiple threads to run on each core and increasing processor throughput. Now, you can run multi-threaded applications with noticeably fast speed, and perform multiple tasks with astounding responsiveness and smoothness.

general information

Robust Security

Start up your system safely. The Intel Core i7-5820K Haswell-E processor employs advanced security technologies – including Intel Identity Protection Technology, Intel Data Protection Technology (Intel AES New Instructions), and Execute Disable Bit Technology – to ensure maximum security.

general information

Enhanced Intel SpeedStep Technology

Enhanced Intel SpeedStep Technology is an advanced means of enabling high performance while meeting the power-conservation needs of mobile systems. Conventional Intel SpeedStep Technology switches both voltage and frequency in tandem between high and low levels in response to processor load. Enhanced Intel SpeedStep Technology builds upon that architecture using design strategies such as Separation between Voltage and Frequency Changes, and Clock Partitioning and Recovery.

Thermal Monitoring Technologies

Thermal Monitoring Technologies protect the processor package and the system from thermal failure through several thermal management features. An on-die Digital Thermal Sensor (DTS) detects the core's temperature, and the thermal management features reduce package power consumption and thereby temperature when required in order to remain within normal operating limits

Intel Virtualization Technology

Intel Virtualization Technology for Directed I/O (VT-d) continues from the existing support for IA-32 (VT-x) and Itanium processor (VT-i) virtualization adding new support for I/O-device virtualization. Intel VT-d can help end users improve security and reliability of the systems and also improve performance of I/O devices in virtualized environments.
