Core i7-3770K Vs Core i7-3820

- The Core i7-3770K and the Core i7-3820 are processors from different categories and there is little common between them as far as the architecture goes.

- The Core i7-3770K belongs to the newer Ivy Bridge group while the Core i7-3820 is a part of the Sandy Bridge E processors. Notice that Sandy Bridge E is a different from Sandy Bridge – it is a different die, has quad core memory channel.

- The sockets of the two processors are different. The Core i7-3770K will use the LGA1155 socket while the Core i7-3820 needs LGA2011 socket. Expect the motherboard for the i7-3820 to be slightly more expensive.

-In processor performance the Core i7-3770K is slightly better, owing to its improved Ivy Bridge architecture.

-The i7-3770K also comes with integrated Graphics. The Core i7-3820 does not come with any integrated graphics.

Some more details of Core i7-3770K

The Core i7-3770K bumps up the base clock frequency of the Core i7-3700 by 100 MHz. The Suffix K denotes officially unlockable part , and , owing to the 22 nm Ivy Bridge process. Given the same clock frequency, the Ivy Bridge processor is expected to provide 10 to 15% more improvement over the Sandy Bridge processor.

Some more details of Core i7-3820

The Core i7-3820 is DIFFERENT from othe core i7 Sandy Bridge processors. It is a part of the Sandy Bridge E-Series and has a bigger LGA 2011 socket. It will require a different and slightly more expensive motherboard to support LGA 2011 socket. The regular Sandy Bridge processors have Dual Channel DDR3 lanes, while this one has quad core DDR3 lane making the memory transfer fast. The processor has been priced competitively at $285.

The Intel Core i7-3820 is the cheapest Sandy Bridge E processor that will fit in the LGA 2011 socket. It has only 4 cores ( unlike the i7-3960X and i7-3930K that have 6 cores), but has higher base and turbo clock frequencies. In overall, you will be a comparable low threaded ( upto 4 cores) performance. It has quad core memory channel. The Core i7-3820 does not support native overclocking ( it is not a K part). If you are looking at a low cost system, this $294 processor has great potential that could be upgraded to higher processors if required.
