Intel Core i7 3820 review

The four-core version of Intel's extreme CPU lineup

TODO alt text

The Core i7 3820 actually posts some decent scores but it's the Core i7 2700K that makes the best impression thanks to some stellar comparative benchmarks.

In single-threaded applications the straight Sandy Bridge architecture has the edge in our test, showing why the gaming performance is higher as well.
