AMD Performance Midrange

The introduction of Phenom II has made putting together an AMD performance midrange a joy again. 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 Quad processors was always a nagging reality. Phenom II changes all that, and AMD in 45nm clothes is once again a screaming overclocker. We reached 3.9GHz in our testing for the Phenom II launch with a Phenom II 940 CPU. That same CPU is the starting point for our AMD performance midrange PC.

For detailed information on the Phenom II, please read our AMD Phenom II launch article and the follow-up Phenom II X4 810 and X3 720. The Phenom II 940 at 3.0GHz is the fastest of the currently shipping AMD Phenom II processors, but that will likely change in a few weeks. The Phenom II is very similar in L2/L3 cache configuration to the Intel Core i7. Performance is also similar to comparably priced Intel midrange chips. As the first 45nm AMD processors the Phenom II also overclocks very well, finally approaching the overclocking levels enjoyed by Intel since the introduction of the Core 2 Duo.

The component that made the early Phenom II systems affordable was the Foxconn A79A-S motherboard, which is compatible with AM2+/AM2 and is based on the AMD 790FX chipset. The selling price of this Foxconn A790FX board was $224 just a few months ago. Today it is available for $140, and we have seen it as low as $105 with the rebates that come and go on this board.
 
This Foxconn board offers true dual x16 PCIe slots, which may be important if you plan to run Crossfire. If that is not important and single x16 or dual x8 PCIe will be fine, then you might consider a 790GX board with DDR2 support. These can be easily found for $100 or less, saving $40 to $45 on the system price. Performance is similar to the 790FX, though our Motherboard Editor still recommends the older FX chipset where squeezing the very last bit of performance matters.

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 940 with the Xigmatek Dark Knight, which performed well in the lab. At $40 the Xigmatek is also an excellent cooling value.

Since the Phenom II 940 does not support DDR3, our DDR2+ motherboard was populated with a 4GB kit of OCZ Reaper HPC DDR2-1066. This memory is rated at a fast 5-5-5 at DDR2-1066 and it performs at faster timings and lower voltages at slower speeds. Whether you use it as a stock DDR2-1066 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 case for the Phenom II performance midrange system is the well-regarded Lian Li black all aluminum case. This Lian Li case has a reputation for exceptional quiet with its four 80mm fans with a fan speed controller and the excellent heat dissipation you expect from an all aluminum case. What is unique is the $40 savings on this case through the month of April, which reduces the cost to $100. There is even a side window for those who like a view of their working 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 components on the previous page.

Finally, you should notice that the AMD performance system, using the current top Phenom II and DDR2 memory, is around $180 cheaper than the Intel Core i7 performance midrange system. The reason for this is very simple, and that is that the Core i7 is a better performing system. 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 performance. There are always exceptions to a broad statement like this, but generally pricing and performance are fairly gauged in today's market.
 
You might also consider waiting for the AMD Phenom II high performance CPU that fully supports Socket AM3 and DDR3 memory.  AMD will soon replace the 940 and 920 with updated processors that fully support the latest Phenom II AM3 socket.  Performance of the 940/920 replacements will not likely be better than the current 940/920, but the future Phenom II upgrade path will be cleaner.

    I have the Xigmatek on my recent C2D build and it is fantastic. The pushpin design sucks, but if you opt for them the price is closer to the other more expensive designs (Ultra120, etc.).

    If the Dark Knight (aka 1283V) is anything like the original 1283, it'll be a superb choice. SPCR reviewed the 1283 and found that it cooled essentially as well as a TRUE while being substantially lighter and cheaper.

    Thanks. I think I'll pick up one of these puppies.

    @iAURA: note the addition of monitor, OS, speakers etc. The core system is still around $500.

    I've been looking at memory a lot lately and I'm surprised by the DDR2 choice. There are other kits out there for around the same A/R price with better timings at lower voltages, just seems like you went with a generic choice, not necessarily the best "bang for the buck" as with the other components.

    I'm extremely puzzled by your comment. If you search DDR2-1066 you will not find a single DDR2 kit at Newegg rated better than the 5-5-5 timings of the OCZ and Patriot DDR2 kits. You CAN find faster DDR2-800 kits, but keep in mind that a 5-5-5 rated DDR2-1066 kit can normally run at much faster timings at DDR2-800. So your comment that faster kits are available is simply not correct.

    Second, anyone shopping for memory knows that OCZ Reaper, Corsair Dominator, and Patriot' DDR2 are NOT generic memory choices. The kits we selected are good values, but also great memory kits.

    You need to UNDERSTAND how memory works - not just compare specs that aren't even apples to apples.

    doh! no edit button. re-looked at the pricing and it's not even close to $500 - for the average "enthusiast" though you can usually save on the cost of optical drive, HDDs, etc. pulled from a previous system.

    Even (or especially) the 550W for a value mid range is overkill. I'd go for no more than 400W in those and the 550W (at most) in the performance box. CF/SLI "future proofing" is a silly thing to do for most people.

    $1800 is midrange??? wow, u sure do have money to burn. That's not mid-term on my salary.:0
  • Wesley Fink - Wednesday, April 8, 2009 - link

    As mentioned in the article, if we exclude the stretch to a system with the lowest cost Intel Core i7 our range is $800 to $1600 for a complete system or $740 to $1060 for the basic mid-range box without peripherals. The problem is we would have a difficult time recommending a $1600 Core 2 quad system to a buyer when that is so close to the cost of a well-balanced and better performing Core i7 920 system.

    We also buy and build systems, so we strongly believe the buying context and competitive environment should be strongly considered in a system purchase. If the $1800 Core i7 system is too rich for you then look at the Value Mid-Range systems at less than $800 for the box and about $1150 for a complete system with US and a 24" 1080p LCD. You may also want to take a look at the recent Under $800 system guide with basic boxes at $300 to $500.

    With OS that is - a complete system with Operating System and LCD monitor and speakers and keyboard/mouse.
