Closer Look
The processor we have for review today is the Intel® Core™ i7-3820 processor. It is a 4 core, 8 thread 32nm CPU with a stock speed of 3.60 Ghz featuring 10MB of L3 Smart Cache and a maximum Turbo frequency of 3.80 Ghz. Missing in this edition is the integrated Intel HD Graphics! But the increased memory bandwidth, quad channel memory support, and a built-in 40-lane PCI Express 3.0 controller more than makes up for the lack of the embedded graphics option.
