Sorry for writing in English, but the i5-3570K will use the 4+2 die, as the 4+1 die only has HD2500 graphics. The Spec code for the i5-3570K E0 stepping qualification stage engineering samples is QC1Y, and the Spec code for the production 3570Ks is SR0PM. If you search for either in Intel's MDDS Database, it indicates that the 3570K is based on the "Ivy Bridge-HE-4" die, which is 4+2. The 4+1 die is "Ivy Bridge-HM-4". There are a few processors listed based on that die, but their spec codes haven't yet been identified. Even the i5-3450 (SR0PF) with GT1 graphics is based on the 4+2 die. I suspect that the 4+1 Ivy Bridge-HM-4 die won't come into use until sometime after launch, perhaps around the same time that the dual core Ivy Bridge CPUs come out.
