AMD Performance Midrange

With Phenom II, an apology is no longer needed when putting together an AMD performance midrange system. While the Phenom was an honest competitor at the price points where AMD chose to compete, the poor overclocking of the AMD Phenom compared to Intel Core 2 Duo and Quad processors was always a nagging reality. Phenom II changes all that, and AMD in 45nm clothes is once again a screaming overclocker. We have reached 3.9-4.0GHz in internal Phenom II testing, which places the Phenom II squarely into Intel Core 2 overclocking territory. The days when AMD meant lots of overclocking headroom have finally returned - at least through the midrange CPUs.

The Phenom II 955 Black Edition at 3.2GHz x4 is the fastest of the currently shipping AMD Phenom II processors. Recently the Phenom II 955BE has been frequently on sale, as it is right now for just $199.95. That is a great price on the flagship Phenom II and it brings tremendous value to the AMD performance midrange system. The Phenom II is very similar in L2/L3 cache configuration to the Intel Core i7, but i7 is clearly the better performer and the fact it sells for more reflects that reality.

We've paired the Phenom II 940 with the MSI 790FX-GD70 motherboard based on the 790FX chipset. While the 790FX is an older chipset than the 790X and 790GX, it still provides features like true dual x16 PCIe slots that are not available in the newer chipsets. Internal testing also shows performance is slightly better with the FX chipset than the newer chipsets, making this board an ideal match to the top 955BE Phenom II.

Since the MSI supports dual-channel DDR3, the motherboard was populated with a 4GB kit of OCZ Platinum AMD Edition. This low-voltage memory is rated at 7-7-7 timings and DDR3-1600 at just 1.65V. It performs well at faster timings and lower voltages at slower speeds. Whether you use it as a stock DDR3 memory or overclock it to its limits, this OCZ memory should provide the headroom you need to bring out the best in this system.

The Phenom II is not the hot CPU you find in the Core i7, but it still benefits from third party cooling - particularly if you plan to overclock. We paired the Phenom II 955BE with the Xigmatek S1283 120mm Rifle that performed well in the lab. At $27 after a $10 rebate, the Xigmatek is also an excellent cooling value. It is the same cooler recommended for the AMD value system.

Other components in the AMD performance midrange system are the same used in the Intel performance midrange. You can find descriptions and thumbnail images of those common components on the next page.

Finally, you should notice that the AMD performance system, using the current top Phenom II and DDR3 memory, is around $150 cheaper than the Intel Core i7 performance midrange system. The reason for this is very simple, namely the Core i7 is a better performing system that is priced accordingly. It just means AMD and Intel are competitively priced these days and the comparative costs of an Intel or AMD CPU is now a good indicator of the relative performance. There are always exceptions to a broad statement like this, but generally pricing and performance are fairly gauged in today's market.

    The idea that the 4870 or the 4890 beats the GTX275 is a FANTASY.

    If you're spending $700.00 to $1,600 dollars and a $15 difference on one of your most important components, the videocard, makes your mind up for you... well...
    ---
    NVidia often has 1 or TWO free games with it at the egg - while the red card far less often has just 1. There's another $50 - or $100, going with Nvidia - because of course with either card that makes it a GAMING system - and one would need some games.
    ---
    I wasn't surprised that EVERY CARD in EVERY SYSTEM recommended was the red rooster card - considering where we are.

    Hiya, for HDD choice you write
    "While there are differences between hard drives, outside of running benchmarks most people aren't likely to notice the difference in performance between Western Digital, Seagate, Samsung, Hitachi, and other major brands." -

    but for memory, you recommend an overclocking memory set, where you could easily save some money (and you don't even give an alternative "for the people that will never want to overclock at all).

    .. I don't see any point in advising only overclocking stuff. Sure one might want to overclock, but in this case you could add something as an alternativ, not recommend the OC stuff in general.
  • Wesley Fink - Monday, July 27, 2009 - link

    Even if you never overclock the low-voltage designs of the memory we recommend in the Guide will perform well and last a last time. You can certainly substitute lower cost and lower spec'ed memory if that better meets your needs.

    Search for a standard like DDR2-800 for the DDR2 systems and DDR3-1066 or 1333 for the Performance mid-range systems. Name brand memory with a real warranty is the better choice - even at the low end. If anything goes wrong quality memory suppliers will replace the bad memory quickly and many better companies offer a lifetime memory warranty.

    In comparing memory at the same price choose the one that has the tighter timings, like 5-5-5 instead of 7-7-7. At the same timings and price the one that is specified with the lower voltage is generally the better choice.
  • nafhan - Monday, July 27, 2009 - link

    I think they recommended overclocking memory because they are recommending overclocking in general at this price point. Notice the processor and motherboard choices are geared towards overclocking as well. If you are definitely NOT going to overclock the value midrange, you could buy cheaper memory, motherboard, and (on the AMD side) a non-black edition CPU. You'd save about $100, and still have a fast, reliable system.
    It might be interesting if they listed a non-overclocking alternative for those parts (Mem, CPU, MB). Although, that may just push things down into the "budget" system range.

    can anyone tell me if the OCZ ModXStream Pro is better than the ENERMAX PRO82+ http://www.newegg.com/Product/Product.aspx?Item=N8...">http://www.newegg.com/Product/Product.aspx?Item=N8... ? they are both about the same price

  • The0ne - Monday, July 27, 2009 - link

    I don't know about the enermax but I've researched before purchasing my OCZ 700W PS. Their lower wattage PS have good reviews except for this one but with the recent updates it's gotten better reviews. It was below average before. Sorry I don't have the link to the website that reviews PS.

    One thing to keep in mind is that if you're not really going to use the max wattage then I wouldn't worry about it. Also, it's best to know your system configuration and try to get a PS with some buffer wattage just in case....you know like when it ages :)
  • Wesley Fink - Monday, July 27, 2009 - link

    Today's price on the OCZ Modular 600W is $50 after a $20 rebate, or an initial cost of $70. The Enermax is a decent PSU, but current cost is $60 after a $50 rebate or an initial cost of $110.

    The OCZ slightly higher power rating, modular design, and 3-year warranty tilt the value toward the OCZ. Both units are 80 Plus certified, and OCZ has an excellent reputation for Customer Service.
  • C'DaleRider - Monday, July 27, 2009 - link

    That OCZ ModXStream isn't even in the same class as the Enermax Pro82+. Interior construction----the OCZ uses Chinese off-brand capacitors while the Enermax uses high quality name brand Japanese capacitors.

    Efficiency----not even a contest, the Enermax by a landslide.

    Voltage regulation and ripple/noise suppression----again, the Enermax trounces the OCZ.

    In all, the OCZ is a mediocre power supply that failed testing when subjected to temps above 40C. On the other hand, the Enermax is better constructed, more efficient, and flew through testing despite being subjected to temps in excess of 40C.

    You make the call.
  • jonup - Monday, July 27, 2009 - link

    First the Enermax comes with $50 MIR. Which is a turnoff for many.
    Second, I just bought OCZ ModXStream Pro 600W (it should ship today) and I did some reading before I bought it. Non of the reviews had an issue with the performance. It performed as rated or better with stable voltages.
    Third, for a midrange system it should be running in less then 400-450. At such output the OCZ if working 2 85-86% efficiency. I am not saying that it is better than the Enermax, but in worst case the OCZ will be behind 1-2% which is immaterial.
  • erple2 - Monday, July 27, 2009 - link

    My system (non-overclocked E6750, radeon 4890, 2 memory sticks etc) eats about 325 W at the wall when running at or near full tilt. Factoring in even the highest efficiency available for my PSU (85%), the system is using about 275W of power. I think that the midrange systems listed here (particularly the lower midrange ones) will be chewing through about 300W at full tilt. So I think that the 600W psu should be more than enough.

    Yes, you can play games with specific efficiencies at specific wattages, but for that you're going to need to see the charts to make that fine-tuned an estimate. But, most power supplies that I've seen reviews for hit max efficiencies between 30 and 60% utilization.

    Also, does that extra few percentage of watts make that much of a difference? I dunno. Turn off a light instead. That will save you more power.
