Intel’s ultra-low-voltage (ULV) SNB has a TDP of 17W, divided between a GPU and two cores. At 700mV, 1.4GHz is the typical operating frequency for these cores.
Each core in our hypothetical processor includes 32KB L1 instruction and data caches and a 256KB Mid-Level (L2) Cache. All cores share a 4MB Last-Level (L3) Cache.
