Intel Core i5-3570K Vs i7-2700K
– The Core i5-3570K belongs to the newer Ivy Bridge series ( launched April 12, 2012), while the Core i7-2700K is an earlier Sandy Bridge processors.
– Both are quad core. However, Core i7-2700K also support Hyperthreading.
– The Core i7-2700K has slightly higher clock frequency. Even though the newer Ivy Bridge is slightly faster ( clock to clock about 10%), the Core i7-2700K has been found to be slightly better in Synthetic benchmark.
– But the main reason of preferring the i5-3570K has to do with its Integrated graphics. The HD Graphics ( called HD 4000) in i5-3570K is about 50% better than the HD Graphics 3000 in Core i7-2700K.

The Core i5-3570K belongs to the Ivy Bridge group of processors which makes significant improvement in the integrated graphics using its HD Graphics 4000. The newer 22 nm manufacturing process promises better power envelope performance. In CPU area, you can expect a 10% performance improvement over Sandy Bridge. At $332, the Core i7-2700K is a good value for money, if you plan on using the processing power it provides. It has a high 3.5 GHz base clock making it great for extreme processing. You will need a good external graphics card, since, the Integrated HD 3000 is not great for high end computing. Some more details of Core i7-2700K
