It's unrealistic to compare 32 bit and 64 CPUs, produced with the same level of development. Could you provide some examples? Actually I'm comparing two CPUs from the same family. The CPU I'm using for my desktop computer today and the last 32 bit CPU I used for my desktop computer before I switched to 64 bit. My old 32 bit was an Athlon single core 800, 850 or 900 MHz, I don't remember exactly, Socket A, so the consumption was between >= 42.6 W and <= 49.7. My current, newer 64 bit dual core is an Athlon BE-2350, 2100 MHz, Socket AM2, 45 W. >Assume that two CPUs are produced with the SAME technology . >A 64 bit CPU will contain more circuits than a 32 bit CPU , means more >power it will use because amount of power will be proportional to >number of circuit components and length of connection lines . But they are not produced with the same technology, the 32 bit Athlon I mentioned requires 1.70 V or 1.75 V, the 64 bit Athlon I mentioned 1.25 V, they are anyway from the same family, they were just not produced with the same level of development. The slower CPU, slower RAM, different hardware, IDE etc., made the old computer almost half as fast, so it needs to run almost double the time, to reach the same processing power. https://en.wikipedia.org/wiki/List_of_CPU_power_dissipation_figures#AMD_Athlon_64_X2_.2F_Athlon_X2 http://www.anandtech.com/show/557/3 Regards, Ralf
