AMD Athlon II X2 / Phenom II X2 And Low-Power CPU Bonanza

Benchmark Results: Productivity

A lack of threading makes this compression utility less interesting than the new version of WinRAR that follows it. Nevertheless, the Phenom II X2’s first-place finish here is notable. Both of the Intel CPUs perform comparably, and an IPC advantage in favor of the low-power Phenom IIs allows it a win over the 3 GHz Athlon II X2.

The latest beta of WinRAR incorporates 64-bit support and better thread utilization, so again, the two quad-core competitors place first and second (though it’s the low-power Phenom II X4 905e on top this time). A 600 MHz clock rate advantage allows the Phenom II X2 to sneak past the triple-core Phenom II, but the X3 705e does manage a fourth place finish. Both the Athlon II X2 and Pentium E6300 bring up the rear.

Also 64-bit-enabled and thread-aware, 3ds Max 2009 shows a clear proclivity for our quad-core contenders, handing the Core 2 Quad Q8400 a small victory over the Phenom II X4 905e. The tri-core X3 705e takes third place, and the higher-clocked dual-cores fall into place immediately after.

AVG does a great job demonstrating the benefits of multi-core processors, as the scaling from quad- to triple- to dual-core computing is bright as day.

With Photoshop CS4 now in our suite (and loaded with threaded filters), it’s easy to see the benefit in jumping from AMD’s triple- and dual-core chips to its quad-core 905e. Similarly, there’s a huge difference between the Pentium E6300 and Intel’s Core 2 Quad Q8400.

    Maybe if AMD would actually bring out some kind of nehalem competitor instead of flooding the cheapo market with variations of the same chips all over the place. There was Athlon 64 X2, brisbane and windsor, then there was Kuma, which was a phenom with 2 cores disabled. Now we got these new chips which are phenom 2s with 2 cores disabled. Lets put the money into some R&D and get somewhere. It seems like AMDs lost traction. sad.

    The low to mid-price segments are the best selling hardware categories.

    Believe it or not, the $100 bang-for-the-buck graphics cards by far outsell the $500 space heater graphics cards. As with graphics cards, $50-100 CPUs by far outsell the $300-1300 CPUs.

    The market that seems like most of the market - the enthusiasts and gamers - is actually not that much of the market share. Businesses building for performance-per-dollar, low-mid performance factory built home PCs, and people building web or media machines... these together outweigh the enthusiast/gamer market.

    Those Phenom II 905e's and 705e's would be kickass if paired with the upcoming 785g motherboards.
    AMD has some new interesting CPU's.

  • @IronRyan: Why not start your own semiconductor company and show AMD how it's done? Can a similar argument not be applied to Intel's "double cheeseburger" quads, and "single patty" dual-cores? If we even get any non-quad i7/i5s, do you know if Intel won't just do the same thing? In the future, instead of coming up with some lame argument, just post this for each article:

    "Hi, my name's IronRyan, and I like Intel. Go team Intel, yay!!!!!"

    Anyone else see the Athlon X2 and think that if they underclocked and undervolted it they'd finally have a legitimate mobile contender?
    If they can run 4 cores at 2.5ghz and 8mb cache on 65w they should be able to run 2 cores at 2.5 ghz and 2mb cache at less than 32.5w.

    Interesting article...I'm glad you put this against the E6300. I haven't seen much about this chip. It as if Intel just snuck on onto the market. I wonder how high of an overclock you can get with it....

    Onto the article, it seems as if the Phenom II x2 550 BE would a great chip in a value gaming rig. If you could unclock the extra cores and get it stable, you'd be one lucky man. Can't wait till see these on the Egg...

    Quickest Pentium, only one with a 1066 MHz bus, disappointing that it's missing some functionality, though.

    Anyone else reminded of GeForce 2 MX when they see how Intel is positioning its mainstream chips these days? I'm all for differentiating with performance to drive down price (even cutting performance-oriented features, like Hyper-Threading), but don't start shedding the actual capabilities of an architecture to handicap it.

  • I would find the Phenom X2 550 interesting because many of the programs I still run today are singlethreaded.
    These programs benefit more from a higher clockrate than more cores.

    Keeping this in mind, and the fact that an OS doesn't (spectacularly) boot faster with more cores, I think the X2 is a great buy.
    I'm a bit dissapointed at the powerdraw. For a HDTV box you don't necessarily need to buy a Radeon 4850. Perhaps a lower powerdraw (and price) in the 4770 or 4670 will be better.
    To playback full HD (1080p) I suppose a Radeon HD 2900XT would be enough.
    Add office tasks, internetting, some photoshop, and casual gaming on a 22"monitor (1680x1050 pix), and a Radeon 4670 would be enough in most cases.
    If you have a 24" monitor (1920x1200 pix) a Radeon 4770 would do.
    Only when latest gaming is concerned should you go for a Radeon 4870 or a 4890.

    Pro, for an HTPC, you'd be fine with a 4670, more than likely. The challenge will be building a system able to keep that setup cool enough. The Maui box with the 905e was *near-silent* but a discrete card would have wrecked this, and a 4670 is almost too much card to be passively-cooled (a la Ultimate-style) without better airflow in the case.
