Power Consumption  

We looked at power consumption of our two testbeds, however AMD is at a bit of a disadvantage here. While our Intel testbed uses the P965 chipset, the AMD testbed uses NVIDIA’s nForce 590 SLI, a far more power hungry platform. The results below are thus better for comparing within platforms and not necessarily useful for drawing AMD vs. Intel comparisons. Note that we did use AMD’s latest 65nm Brisbane core for all of our tests.

At idle we can see that the E4300 system already uses less power than the E6300, and definitely less power than the Pentium D 945.

Total System Power Consumption at Idle

Under load, power consumption is once again reasonable - lower than the E6300. Overclocked, the E6300 uses a bit more power than the X6800 but that’s to be expected.

    Nice OC and I might consider this instead of a E6400. I'll have to wait how the 4MB versions stack up. Also, I'd like to see how it OC's on a Nvidia chipset board. No DS3 for me. Reply

    The 4MB cache and faster FSB is good for performance, but also for raising stock performance from Intel's point of view. The extra cache and more bandwidth enables Core 2 Duo to scale better than the ones that don't. I would like to see E4300 at 800MHz FSB and clocked to say even E6600 speeds to see how it scales but I am expecting too much :P.

    E4300 at 3.38GHz has an FSB of 1500MHz, which is 40% more than the stock X6800.

    From the idle power consumption measurements, it seems to use the new Core 2 Duo steppings that has C1E power consumption of 12W. You can see 8W difference from the normal Core 2 Duos, which are at 20W-22W(20W for E6700 and 22W for others). Reply

    Yeah, but that doesn't matter to 99% of the desktop consumer market. Most only care about power consumption at full load as it is usually a good indication of heat output. Reply

    The only people that care about power consumption are geeks and corporate IT departments. Joe SixPack doesn't know and doesn't care. All they want is a machine that does email, stores porn, and surfs the web. You guys need to get out more often.

    You can be sure even Joe SixPack will notice if turning on his PC sounds like a jet engine starting up, though, and higher power consumption means louder cooling solutions. Reply

    J6P still won't notice because they usually buy low rent Dell's and HP's not, custom built jobs like we have. Like I said, power consumption means nothing to regular computer buyers.
