Overclocking

All three chips here are easily overclockable. The Phenom II X6 1100T could hit 4GHz however not stable enough to make it through our test suite with stock cooling. I ended up at 3.89GHz for the 1100T:

The Athlon II X3 455 proved to be even more potent than the 450 sample I tested last time. I managed a 3.85GHz overclock out of this one:

The 3.85GHz overclock held even when I enabled the chip's disabled 4th core.

Finally the Phenom II X2 565 BE hit an impressive 3.92GHz even with a third core enabled:

While overclocked the best value continues to be the Athlon II X3 455 which now performs like a Clarkdale Core i5. Unlock the fourth core and the Athlon II X3 455 is faster than a Lynnfield Core i5 in threaded applications:

Overclocked - x264 HD Encode Test - 2nd Pass - x264 0.59.819

You do pay the price in power consumption, the added voltage necessary to reach these higher clock speeds manifests in much higher power consumption. Such is the tradeoff with most voltage overclocking:

Overclocked - Idle Power Consumption

Overclocked - Load Power Consumption (x264 HD Pass 1)

    kind of surprised sandy bridge wasn't even mentioned in the conclusions...

    considering these cpus will only be competing with the westmeres for less than a month before sandy bridge is everywhere...

    AMD seems to only be able to compete on price, kind of sad.

    It'll likely not change as long as Intel is >18 months ahead in terms of process technology used in fabrication.

    This opens the door for another article comparing the Sandy Bridge processors (when they will be available) to the current (for now) offerings. I'm too waiting for the Sandy Bridge launch (but I probably won't buy one) Reply

    Intel is still selling C2Ds. What makes you think SB will be everywhere any time soon? Intel are always slow with their new releases (not easy supplying the whole globe I would think). Reply

    Doesn't the US come first? Reply

    Think again... Almost all tech companies release products in Asia first. Reply

    I think there is more to it than just price, Intels issue is how fragmented it's market is right now, I like to start with a cheap build, mid range CPU and know I have upgrade options, if I did an AMD Dual Core right now I know that I can go to a 6 Core later for some great performance when it's economically possible.

    If I go i3, I have very few upgrade options, need a new motherboard for i5, then If I want to move up from there yet another motherboard for i7..

    I personally think this was the worst way to go about covering all areas of the market.

    Except if you went Lynnfield right now, you would already be ahead of AMD's fastest 6-core offering. And much cheaper than buying a $100 processor now, with another $200 processor later.

    And to the other guy, Intel ramps slowly? Uhhh, not really. Core i7 has been around for 2 years now. In its many flavors. The reason Core 2 Duo still sells... It is actually MUCH faster than that Athlon II x3 Anand just tested.

    LOL... no it's not. I really don't know where you got that from. Reply

    Intel E7500, still selling on newegg for $125. AMD Phenom II X2 560 Black Edition is currently $99 yet wins 17 out of 26 tests on anand's own bench, and is about 5% faster overall. So for 20% less you get faster performance, plus the opportunity to unlock a free bonus. But you can bet the intel part still sells 5 times more. Reply
