Core i7-3820 quad-core desktop processor

The Intel Core i7-3820 is a quad-core desktop processor built on 32nm Sandy Bridge-E architecture. It runs at 3.6GHz with a 3.8GHz Turbo Boost frequency and a 130W thermal design power. The CPU fits the LGA 2011 socket and provides 10MB of L3 cache plus 4 x 256KB of L2 cache.

Suits workstations needing four cores

This processor fits users building an LGA 2011 workstation that relies on four physical cores with Hyper-Threading. It supports quad-channel DDR3 1600 memory and includes virtualization technology for multi-OS environments. Builders who require an included cooler or a lower power envelope should look at other options.

130W TDP dictates cooler choice

The 130W thermal design power is the specification that determines whether this part fits your thermal solution. A compatible LGA 2011 cooler rated for at least this heat output must be sourced separately because the box contains the processor only. Voltage operates between 0.600V and 1.350V under load.

Frågor om den här produkten

Should I pick the 3.6 GHz or 3.8 GHz figure when comparing this Core i7-3820 to other CPUs?

The processor runs at a base frequency of 3.6 GHz and can reach 3.8 GHz with Turbo Boost when thermal headroom allows, so use 3.6 GHz for sustained-load comparisons.

What does the 130 W thermal design power mean for my cooler choice?

A 130 W TDP indicates the heat the cooling solution must dissipate under load; you will need a CPU cooler rated for at least 130 W because none is included in the box.

Which memory standard does the LGA 2011 memory controller support and at what speed?

The integrated controller supports quad-channel DDR3 at 1600 MT/s, so populate four DIMM slots with matching DDR3-1600 modules for full bandwidth.
