Intel Core i7-4820K

The Intel Core i7-4820K is an ideal choice for users who want the highest performance at an affordable price. Compared to the previous generation, Ivy Bridge-E brings a significant increase in overall computing and gaming performance, especially thanks to the four cores utilising the Hyper-Threading technology for simultaneous processing of up to eight threads. Along with an unlocked multiplier and the advantages of the 22nm manufacturing process, these attributes give this processor an excellent price/performance ratio.

Major Core Overhaul

Data access is extremely fast thanks to 10 MB of cache, which ensures immediate response in all applications.

The Ivy Bridge-E processor family also introduces a quad-channel memory controller with a phenomenal maximum transfer rate and a full-fledged quad-channel memory support for the frequency of 1866 MHz. Additionally, the efficient algorithms of the memory controller bring you an incredibly low latency and guarantee high performance even in the most demanding applications.

Automatic Overclocking

The second generation of the Turbo Boost technology boosts the clock frequency up to 3.9 GHz and enables the cores to exceed their stock frequency. The maximum frequency depends on the number of active cores, while the length of the overclocking period depends on the workload and operating environment. The upper frequency limit is determined by reaching threshold values of the four indicators (number of active cores, electric current drawn, power consumption, CPU temperature).

Key Features

  • A high-performance CPU with 8 logical cores
  • Compatible with the LGA 2011 socket 
  • Maximum frequency up to 3.9 GHz
  • Requires a high-quality cooler

This is not news, but despite that, along with the GTX970 in tough games encumbers. about 60%. It did not heat up too much, but it depends on the cooler, since it comes without it.
