Again, this is not so simply (black or white). In some reviews (I dont know, if half of reviews or less or more) was 8150 power consumption lower than 1100T at stock. Of course, theris big difference in OC load. 8150 after is near SB-E CPUs. If u saw graphs voltage/power consumption, every chip is horrible in power consumption from some point, depens at voltages. Man must find some compromise between OC and voltage. IB has great power cons., but from some voltage is worse than SB with high voltage.
