AMD Value Midrange

Once again the AMD value midrange system is built around the Phenom II 720BE 2.8GHz triple-core CPU. The 720BE is a Black Edition processor, which means it has an unlocked multiplier and can be easily overclocked if you choose. The Phenom II offers better raw performance than the older AMD processors and much better overclocking. With prices as low as $99 for a Phenom II we can no longer recommend anything less for a midrange system. As has been stated many times at AnandTech, the Phenom II performance matches Intel performance through the midrange (i.e. the Core 2 family of processors). Unless you are looking for a top performing and top-priced Core i7 system then you can choose Intel or AMD in the midrange based on price and features.

The Phenom II 720BE is two steps up from the lowest priced Phenom II X2 550BE. The 3.1GHz dual-core 550BE is also an option here, particularly if your primary system use is gaming. For ripping video and intense video processing the tri-core 720BE is a better choice. For just $119 you get an unlocked multiplier, three cores each with 512KB of L2 cache, and the same 6MB L3 cache used in the X4 Phenom II processors. The rated speed is 2.8GHz, which basically makes this an unlocked 920 with a disabled core. In testing we easily reached 3.8GHz, about the same as the most expensive Phenom II, and you will only miss that fourth core in the few applications that actually take advantage of parallel processing. All in all the 720BE is a value buyers dream CPU.

For ultimate overclocking we paired the 720BE with a Xigmatek S1283 Rifle cooler. The Xigmatek cools very well and it's a bargain at $27 after the current $10 rebate. As a bonus, the S1283 also comes with the hardware for mounting on Intel socket 775. An alternative for heavy overclocks is the Tuniq Tower 120. The Tuniq can move a lot of air and it is superb at dropping temperatures in ambitious overclocks, but it can be very noisy at high fan speeds. It has been selling recently for around $50.

The GA-MA790X-UD4P motherboard uses the AMD 790X chipset. The 790X is very similar to the 790GX chipset except it does not provide onboard graphics. It also supports the newest AM3 processors like Phenom II and DDR2 memory. GIGABYTE combines the 790X with the latest AMD SB750 south bridge. This combo provides one x16 slot running at x16, a second x16 slot running at x8, three PCIe x1 slots, and two PCI slots. There are eight SATA 3Gb/s ports a parallel port, along with support for SATA RAID 0/1/5/10, 2600MHz HyperTransport, and maximum memory of 16GB in four slots.

This is one of GIGABYTE's Ultra Durable 3 boards that use extra copper to lower system temps and enhance overclocking. It also features solid capacitors for long life. Memory speeds as high as 1333 are supported at standard settings, and in testing overclocking abilities were top notch. Those looking to squeeze as much performance out of their money as possible will be very pleased with the GIGABYTE at a price of just $110.

The motherboard rear panel provides eight USB 2.0 ports, two Firewire, PS/2 keyboard and mouse ports, both optical and coax SPDIF out, and six audio jacks for the I-Channel onboard audio. In addition there are two USB headers for internal USB and one additional 1394a (Firewire) header. The GIGABYTE 790X board provides plenty of expansion capabilities for a performance AMD system, as well as excellent overclocking capabilities for those who plan to overclock. One caution with this board is that one PCIe card runs at x16, while with two PCIe graphics cards each slot only runs at x8 speed. For dual x16 slots you will need to run a board with the older FX chipset.

DDR2 memory is supported on this GIGABYTE, so the memory is the same OCZ Blade 4GB kit used in the Intel value midrange. If you prefer DDR3 memory then a good alternative is the GA-MA790XT-UD4P at $130. You will also need to substitute DDR3 memory for our DDR2 choice, and you can check out the Intel and AMD performance systems on p.5 and p.7 for some DDR3 recommendations. The actual DDR3 memory cost today is very close to DDR2 costs so there is little penalty for choosing DDR3 instead.

The rest of the component selections are shared between the Intel and AMD value midrange systems. You can find more information on these component choices on p.3, which details the common system components.

Comparing our $1100 systems, performance is a tossup between the AMD and Intel systems. However, just as AMD finally competes in the 45nm midrange space Intel is set to move to a new midrange architecture and the new Socket LGA-1156. Still, no matter how long or short the parity, the Phenom II competition is good for all buyers. With the prices of computer components generally trending down, both our AMD and Intel value midrange system builds give you room to grow. There are plenty of options to customize some of the components to your liking - such as a keyboard or laser gaming mouse, updated graphics, or an even larger monitor.

    >For instance there are hardly any quality power supplies in the 450->550W range that offer 2 6-pin PCIe connectors (a requirement to run >HD 4870/90 and GTX 260/275 cards).

    Like the Seasonic S12II-430 Bronze (1xPCIe-6, 1xPCIe-6+2)?

    In addition, most GPUs come with a Power Cable to adapt the standard Molex to PCIe-6. The recommended MSI HD 4890 comes with two Power Cables.

    The Xbit Labs article clearly states the trend in PC parts power consumption is downward, not upward. Besides, I'd rather not spend US$25 that I didn't have to. I could use that money to upgrade to a Q9400 or an E8500, something I could use rightaway.

    "Like the Seasonic S12II-430 Bronze (1xPCIe-6, 1xPCIe-6+2)? "

    Not real familiar with that brand. Try finding one in the range I mentioned built by Antec, Corsair, OCZ, Thermaltake, or PC Power & Cooling. And 430W? I have that in a five year old P4 system. I don't think so. I'll spend the extra few clams on something future proof, and apparently others agree. If you have to worry about spending another $25 on an $850+ PC build, then maybe you need to reconsider your spending priorities.

    Seasonic can be found providing OEM service on various model lines for: Antec, Corsair, PC Power and Cooling, and of course under their own Seasonic brand. Actually, the PSUs that Seasonic either designs or builds for Antec, Corsair or the old PCP&P are not as high quality as the PSUs they build under their own brand label.

    Thanks for the info Black Jacque. I did not know that, and I now verified that fact. Of all the PS research I did prior to my build, no reviews mentioned that fact. However, I will still stand by spending a little more on a future proof power supply so as one less thing to have to upgrade. My Corsair 750W will take me into next year's planned Lynnfield build and the new DX11 cards with SLI (hopefully).

    the article is one from the "how much power do we need" round that almost every major hardware review site did.

    however it was more or less questioning the need of 700+ W PSUs for the normal systems (i.e. average home PC).

    you have to account also for the usage pattern. this site is aimed at the hardware enthusiasts. they tend to buy informed or tend to change components often. in the first case, they will ignore the PSU recommendation, in the 2nd case, it comes in handy in the future.

    also have a look at power consumption on overclocked components (f.e. CPUs increase quite dramaticaly with added voltage). IIRC the xbitlabs article did not take into account overclocking (I might be wrong, did not read into details there).
  • brybir - Monday, July 27, 2009 - link

    You keep referring to that article and after raeding it I do find it interesting. But all it says is that usage is trending downword. That trend is based on events that have already happened and then assuming what future events will occur with power draw based off similar past events.

    First, just because the trend is in one direction does not mean that it is going to continue that way in the future. That is to say that the past predicts the future which is simply not true.

    Second, it makes sense to me to spend $25 on a larger power supply than I need "right now" so that I do not have to worry about replacing the power supply later on. You can say that the general power draw will decrease over time but in each individual case that is not going to be necessarily true. I just went from a system with a 65W CPU and a ATI 4670 to a 125W CPU and a 4870 OC using the same power supply. Had I bought the power supply that exactly fit my previous system I would now have to buy a new power supply. So in my case buying a larger power supply has been a great idea and will save me from spending another $70 this time around. Who knows, since its a 550W supply maybe it will last me another three years.

    You are joking, right?

    If you understand how the past can predict the future, its no surprise that AMD improved their process and shaved 30W off this part's (AMD Phenom™ II X4 945) power consumption after a bit more than 5-months of production. (BTW, this part costs US$1 more than its 125W sibling at ZZF.)

    Looking into my crystal ball, I predict ~3 GHz 65W quad CPUs by either AMD or Intel within a year.
  • haplo602 - Monday, July 27, 2009 - link

    each system has at least a 2x PCIex16 board, so the higher watt PSU is an "insurance" for future upgrades.

    anyway the builds are unbalanced in my view. they get away with far too cheap displays.

    my current planed build is 1:1 in components vs lcd cost. My total component cost is about 600 euro, the display will cost me around 500 euro :-)

    but I am more looking at photo editing than gaming.

    >so the higher watt PSU is an "insurance" for future upgrades.

    "The recent, excellent Xbit Labs article "PC Power Consumption: How Many Watts Do We Need?" clearly illustrates that 750W PSUs are a waste of money in the mid-range when not going with SLI or Crossfire. This article shows the trend in PC parts is downward in power consumption."

    I can't even accept the idea of adding a second GPU later when they get less expensive. The general trend is the next generation of GPU outperforms the previous generation in Crossfire or SLI at a lower price.
  • erple2 - Monday, July 27, 2009 - link

    I suppose that's true. However, it's also true that the next generation of GPU also tends to consume more power than the previous generation. Normally, not 2x the power, but 20-50% more power isn't unheard of.

    Though, you're right. Buying a power supply strictly because it makes the PSU itself a little bit more future proof doesn't necessarily make that much sense. How often does the midrange buyer upgrade their systems? Every 2 years? 3 years? What's the reasonable lifetime of a PSU? 3 years? 5 years? Is it enough to last through a full upgrade cycle? If the answer is "yes", then it's certainly possible that buying a slightly higher end power supply can be worth it. You pay the extra 25 dollars now, but save 75 dollars for the next upgrade.

    Unless the next generation of chips use less power than the current gen, which I don't think is going to be the case (the only exception that I can think of in the x86 world was the move from Pentium 4 to Core2Duo), then buying a slightly larger power supply than necessary isn't necessarily a bad idea. Now, going with 750 Watts with a non-SLI, non-XFire setup does seem a bit silly.

    If you overclock, I don't know how that impacts the power consumption of the system, either. Maybe a study on that would be interesting?
